2. Subgrade Protection Measures

2.1 Subgrade Protection

To reduce soil erosion resulted from subgrade filling and excavation and to ensure the safety of the subgrade project, the line of subgrade has been reinforced and appropriate

measures such as retaining wall protection, slope protection by framework or mortar rubble revetment, arched or square slope, planted tank, and new soil grass have been take based on the characteristics of subgrade in different segments. In addition, appropriate drainage system has been designed.

(1) General subgrade slope protection

If the height of the subgrade slope <3.0m, hollow bricks with new soil grass and planted shrubs shall be used; if the height of the slope≥ 3.0m, a layer of two-way geogrid with a limit tensile strength of not less than 25.0kN/m shall be laid every a filling of 0.6m within the width of 3.0m at the outer section of the slope, C25 concrete hollow brick with new soil grass + planted shrubs in water disconnection framework shall be used for slope protection. The main frame shall be 0.6m thick, and C25 concrete masonry shall be used for the water disconnection tank. The interface between the subgrade surface drainage and slope drainage shall be paid attention to. Three-dimensional ecological bags may be considered for the protection of city road segments, scenic areas and ecologically sensitive areas. If the slope of the subgrade height is greater than 8.0m, a different slope rate shall be taken according to the filling height. It is 1:1.5 for the slope of 0 ~ 8.0m, 1:1.75 for the slope of 8.0 ~ 12.0m, and 1:2.0 for the slope below 12 m; and a 2.0m wide platform will be located at 12.0m for the slope. New soil grass and planted shrubs in the hollow bricks in C25 concrete arch water disconnection frame will be used for the slope of 0 ~ 12.0m under the shaller, and dry stone revetment or prefabricated solid block revetment will be used for the side slope below 12.0m.

(2) High subgrade slope protection

If the slope height exceeds 12m, the slope rate is 1:1.5 for 0 ~ 8.0m, 1:1.75 for 8.0 ~12.0m, 1:2.0 for the height below 12 m. A 2.0m-wide platform will be located at 12.0m for the slope. New soil grass and planted shrubs in the hollow bricks in C25 concrete arch water disconnection frame will be used for the slope of 0 ~ 12.0m under the shaller, and dry stone revetment or prefabricated solid block revetment will be used for the side slope below 12.0m. C25 concrete or rubble foot wall of concrete will be positioned at the slope. Gravity retaining wall may be located at some high-fill subgrades with less arable land to reduce the use of farmland.

(3) General graben slope protection

1） For the cutting slope of general clay and all-weathered layer, if the height of the slope is less than 3.0m, hollow bricks with new soil grass and planted shrubs shall be used for protection; if the height is equal to or greater than 3.0m, hollow bricks with new soil grass and planted shrubs in C25 concrete water disconnection frame shall be used for protection.

2） For gravel soil, sandy soil cutting slope, hollow bricks with new soil grass and planted shrubs in C25 concrete arched or square grass window shall be used for protection.

3） For strong-weak weathered soft rock cutting slope whose height is less than 8.0m, hollow bricks with new soil grass and planted shrubs in C25 concrete water disconnection frame shall be used for protection; if the height is greater than 8.0m, hollow bricks with new soil grass and planted shrubs in C25 concrete arch or square grass window shall be used for the lower side slope for protection, hollow bricks with new soil grass and planted shrubs in C25 concrete water disconnection frame shall be used for the most upper side slope for protection.

4） For strong-weak weathered hard rock cutting slope, if the slope height is less than 8.0m,

hollow bricks with new soil grass and planted shrubs in C25 concrete arch or square grass window shall be used for protection; if the height is greater than 8.0m, hollow bricks with new soil grass and planted shrubs in the retaining wall of C25 concrete hollow window shall be used at the bottom, while hollow bricks with new soil grass + planted shrubs in C25 concrete arched or square grass window shall be used at the upper slope for protection.

Weakly- sligthly hard rock cutting: in general, the height of the slope is controlled within 30.0m, and M10 mortar rubbles will be embedded for the slope. Hollow bricks with new soil grass will be used for the protection in the concrete grass window or anchor rod and cable within the framework.

5） In the lots with absence of A, B group packing, if the cutting soil is sand gravel, hard rock, large platform shall be reserved for the foot and side slope of cutting slope, with one level every 8.0 ~ 10.0m, and the slope rate shall be reduced accordingly. C25 concrete grass window shall be used for the slope protection.

6） The types of water disconnection frame slope protection are arch, herringbone and box types. They shall be used based on the soil quality of the slope and the requirement for erosion prevention combined with landscape demand. The spacing between the main frame and the arch shall be 3.0m. For the general soil and soft rock cutting, the main frame is 0.65m thick, and the supporting frame is 0.4m thick; for very soft rock, red clay, swelling (rock) soil cutting, the main frame is 0.8m thick, and the supporting frame is 0.6m thick.

7） Planting tanks in which japanesecreepers and evergreen low shrubs are planted shall be located at the platform of the side trenches in the cutting where retaining wall, pile wall and protection wall are located and the platform from the flooding closed slope lot to the drainage.

(4) Deep cutting slope protection

If the height of soil and soft rock cutting slope exceeds 12.0m, and of hard rock slope exceeds 20.0m, the deep cutting shall be designed, and reinforced protection works shall be set.

1） Gravity retaining wall shall be used in the close of the slope for soil and completely weathered rock cutting, and the height of the retaining wall shall not exceed 4.0m. The measures of slope protection refer to slope subgrade. If the slope height is greater than 15.0m, stratified excavation shall be considered for hierarchical reinforcement or pre- strengthening of the lowest part of the slope.

2） In the lots where the slope height of soft rock cutting and hard weathered rock cutting is not more than 18.0m and there is no adverse impact on the structure surface, retaining wall, concrete window grass slope and framework anchored rod shall be used for protection. The height of the retaining wall shall not be greater than 6.0m. In the lots where the slope height is greater than 18.0m or there is adverse impact of the structure surface or broken lithology, stratified excavation shall be considered for hierarchy reinforcement or pre- reinforcement of the lowest part of the slope, such as prestressed cables, pre-reinforced piles and sheet pile walls. In general, the height of the slope shall be controlled within 25.0m. As the strata of the hard rock along this line is old, the joints are developed and the rocks are crushing, grass window wall shall be used for the slope or the slope shall be closed.

3） The slope rate for excavation of the cutting slope of weakly–slightly weathered hard rock shall be determined based on rock lithology, degree of weathering, level, geological

structure, groundwater and required allocation of earth and stone. If the slope height is not greater than 24.0m and there are no lots with adverse impact on the structure surface, retaining wall, concrete grass window slope, wall and frame anchored rod shall be used for protection, with the height of the retaining wall not greater than 8.0m. If the height of the wall exceeds 6.0m, temporary shotcrete shall be taken for the excavated slope of the back of the wall. If the slope height is greater than 24.0m or there are lots with adverse side effects of structure and broken lithology, stratified excavation shall be considered for hierarchical reinforcement or pre-strengthening of the foot of the slope. The slope height of weak–slight weathered hard rock cutting shall, in general, be controlled within 30.0m. Finishing or pre-split blasting shall be used for the slope within the thickness of 3.0m, and M10 mortar rubbles shall be embedded. Hollow bricks with new soil grass shall be used inside the concrete grass windows or frame anchored rods and cables.

4） Planting tanks in which japanesecreepers and evergreen low shrubs are planted shall be located at the platform of the side trenches in the cutting where retaining wall, pile wall and protection wall are located and the platform from the foot of the flooding closed slope lot to the drainage.

5） In the lots with absence of A, B group packing, if the cutting soil is sand gravel or hard rock, depressed road's extension shall be designed and large platform shall be reserved for the foot and side slope of cutting slope, with one level every 8.0 ~ 10.0m, and the slope rate shall be reduced accordingly. C25 concrete grass window shall be used for the slope protection.

(5) Expansion rock (soil) cutting slope protection

1） The slope design of expansion rock (soil) excavation shall follow the principle of "reduced slope rate, wide platform, reinforced toe, enhanced drainage and appropriate slope protection". The excavation height shall be generally controlled within 15.0m. The rating of the slope height shall not be more than 6.0m. If the slope height of the cutting is less than 10.0m, the slope rate is generally 1:1.75 for weak swelling rock (soil), 1:2.0 for moderate swelling rock (soil), and 1:2.25 - 1:2.5 for strong expansion rock (soil). The width of the slope platform shall not be less than 2.0m for weak expansion rock (soil), and not less than 3.0m for medium and strong expansion rock (soil).

2） If the slope height of the cutting is less than 3.0m, the use of hollow bricks with new soil grass + planted shrubs shall be made for protection; if the slope height is greater than 3.0m but less than 10.0m, the use of hollow bricks with new soil grass and planted shrubs in C25 concrete water disconnection frame (expansion soil) or C25 concrete grass window (expansion rock) shall be made for protection; if the slope height is equal to or greater than 10.0m, a platform in a width of 3.0 ~ 6.0m shall be located at the slope of expansive soil cutting, hollow bricks with new soil grass and planted shrubs in C25 concrete water disconnection frame combined with supporting sewer shall be used for protection; if the slope is equal to or greater than 10.0m, hollow bricks with new soil grass and planted shrubs in framework anchoring rod (or anchoring cable) combined with supporting sewer shall be used for the protection of the slope of expansion rock. The thickness of the main frame of the C25 concrete water disconnection framework shall not be less than 0.8m, and that of the supporting frame shall be 0.6m. The main frame spacing and the spacing between arches is 3.0m.

(6) Loess cutting slope protection

The excavation height of loess cutting slope is commonly controlled within 20.0m. Side-ditch platform in a width of 2.0 ~ 3.0m shall be located at the loess cuttings along the line. M10 cement mortar rubble or concrete solid block masonry shall be used for the platform.

If the cutting slope height H is ≤ 5.0m, concrete hollow bricks with new soil grass and planted shrubs inside shall be used for the slope protection. If the slope height is: 5.0m <H ≤ 16.0m, a small platform in a width of 2.0~3.0m shall be located every a height of 8.0m, and platform drainage ditches shall be located; the slope of the upper Pleistocene strata shall be protected using hollow bricks with new soil grass + planted shrubs in C25 concrete water disconnection framework; in mid Pleistocene strata, the slope shall be protected using C25 concrete space wall (mixed vegetation within). If the slope height exceeds 16.0m, the width of the slope platform shall be 4.0 ~ 6.0m, and drainage ditches shall be located at the platform; the slope shall be protected with hollow bricks with new soil grass and planted shrubs in frame anchoring rod in a length of 8.0m.

(7) Cutting of groundwater development

The slope rate shall be reduced by level 1~2 compared with the groundwater undeveloped section. C25 concrete grassed window or C25 concrete arched water disconnection frame + three-dimensional vegetation network solid soil grass + planted shrubs shall be used. The net frame spacing shall be 2.5m and the main frame shall be 0.8m thick. Water disconnection tank shall be reserved at the top, and supporting sewer in a width of 2.0m and a depth of 2.0~2.5m shall be located every 10.0~15.0m. At the junction of permeable and impermeable sections, a slope platform in a width of 3.0 ~ 5.0m shall be located with drainage ditches in it.

(8) Subgrade drainage works

1) Surface drainage design

① Side ditches, gutters, drains or drainage ditches shall be designed by the slope rate of 1/50, and the top shall be 0.2m higher than the designed water level. The longitudinal slope rate shall not be less than 2‰. The cross-section dimension of water surpassing for drainage facilities shall be calculated based on water flow. The connection with subgrade surface drainage, slope drainage and sub drainage systems shall be paid attention to.

② If the subgrade slope is protected with water disconnection framework, the slope water disconnection tanks on both sides will be the lateral gutters along the subgrade slope. Lateral gutters along the slope shall be located in the lots where C25 precast concrete hollow brick grassed pavement in a depth of 0.2m and a spacing of 10.0m is used.

③ In the lots where cross slope is significant on the subgrade ground, drainage ditches may be located in the top side. If the ground cross slope is not obvious, drainage ditches shall be located on both sides of the subgrade. Drainage plane shall be straight; if a turn is required, its radius shall not be less than 10.0~20.0m, and the length of the gutter shall be determined according to the actual needs. Drains are generally trapezoidal ditches in a bottom width of 0.4m and a depth of 0.6m with a slope rate of 1:1. Cast-in-site C30 reinforced concrete in a thickness of 0.2m shall be used for drainage ditches. The location of drains shall ensure that the water will be led outside the subgrade to prevent it from erosion.

④ C30 reinforced concrete rectangular cover trench shall be used for side ditches in a

bottom width of 0.6m, a height of 0.8m, and a thickness of 0.25m. The drains between the lines in a standard spacing shall have a width of 0.4m, a depth of 0.8m, and a thickness of 0.20m in C30 reinforced concrete masonry. Precast C30 reinforced concrete shall be used for the cover of the side ditch. Trapezoidal side ditch shall be used for non easily weathered hard rock cutting, in a bottom width of 0.4m, a depth of not less than 0.6m and a slope rate of 1:1. M10 cement mortar in a thickness of 0.08m shall be used for the surface, and C25 concrete may be used for embedment at local sections.

⑤ In the lots where cross slope is significant on the subgrade ground, gutters may be located in the top side. If the ground cross slope is not obvious, gutters shall be located on both sides of the subgrade. 0.2m thick in-situ C30 reinforced concrete may be used for the gutters, and M10 mortar rubble shall be used to close the sections from expansive rock (soil), collapsible loess, the top of the bed cutting to the gutter. For the gutter which has the steep slope of the cutting top, rectangular gutter shall be used.

⑥ 0.40m × 0.40m rectangular groove shall be used for the water disconnection ditch at the slope platform for the cutting, and C25 concrete which is used in the slope shall be poured.

⑦ The anti-slope drainage of the tunnel entrance is based on the rigid transition section of the tunnel road, with the cross section of the ditch at the starting position being 0.4m deep. In the deep cutting and the lot with problems of anti-slope drainage（if the depth

of the side ditch is more than 1.50m, and the width more than 0.80m）, and in the valley cutting lots, the addition of culverts and the use of 0.2m thick C30 reinforced concrete drains shall be made to lead the side ditch water out of the subgrade as soon as possible.

2) Base-bed waterproofing and drainage

Collecting well shall be located in the middle of the subgrade for the drainage between the tracks of slab track sections of straight lines and curves lines. The inside diameter of the drainage well is 0.6m, the depth 0.8m, and 0.3m thick cast-in-site C30 reinforced concrete is used. Precast C30 reinforced concrete is used for the cover spaced 50m or so, which are embedded into the drainage channels or side trenches for the slope of subgrade.

3) Groundwater waterproofing and drainage facilities

Drainage facilities such as open ditches, slope support sewers and porous drains shall be located where underground water brings hazards to the subgrade according to its nature and characteristics. Drainage shall be particularly designed for swelling rock (soil) cutting and underground water development cutting.

4) Connection between drainage system and natural system

The drainage system of subgrade main project uses its drains with devices such as wells and settling ponds by being connected to the existing ditches or channels around.

The subgrade slope protection, slope greening measures, drainage works, protective area, quantity and investments of protection, etc taken in the design shall meet water security requirements, and be included in this program investment. For the quantities of soil stripped and corresponding temporary protective measures excluded in the main project list, design will be added to them in the program. Special design of green channel is made for the both sides of the line in the main works, and costs are listed to meet water conservation requirements, but detailed design has not been made in the main engineering. Therefore it is not very targeted and operable, and may not be implemented specifically in the construction process. This soil and water conservation program has detailed design for

the greening sections on both sides of the line, and quantities and investment costs of protection works based on sections have been included.

(1) Temporary block and drainage measures for the subgrade stripped topsoil

During the filling works of the railway subgrade, as the surface soil fails to meet the requirements of subgrade filling in the engineering design, the topsoil must be stripped. The thickness of this surface soil is generally about 30cm. It has high content of humus, featuring good soil fertility, structure and texture. It is suitable for vegetation growth and may be used in the topsoil transformation for the subgrade slope green of grid, station and ballast along the railway.

According to the state of the environment in the project area, combined with the engineering characteristics, the land, woodland and grassland occupied by the subgrade are designed to have topsoil stripping in a strip thickness of 0~30cm, and a temporary stockpiling field is designed every 500~1000m in the land, where the stripped topsoil will be piled up and compacted. Retaining wall made of straw bags will be used as temporary protection at the foot of the outside slope surrounding the stockpiled soil, and other exposed surfaces will be covered with tarpaulin to prevent wind transport. Temporary drains will be dug at the border of the stockpile soil, temporary settling basin will be constructed at the outlet, and connected with the surrounding drainage system, so that the rainfall runoff may be discharged through the outlet and the simple settling basin to prevent soil erosion in the temporary stockpiling field.

The stockpiling height of the temporary stockpiling filed shall not be higher than 3.0m, and the stacked slope rate shall be controlled within 1:1.5. The straw bag retaining wall section shall be a rectangular trapezoidal cross-section in height × top width ×bottom width = 1.0m × 0.5m × 1.5m. When piling, the bags shall be engaged and lapped in a lap length not less than 1/3 of the length of the straw bag. The temporary drains shall be soil drains with a trapezoidal cross-section, whose design specifications are base width of 0.3m, top width of 0.9m, ditch depth of 0.3m and slope rate of 1:1. The ditch base and wall shall be compacted.

The simple settling basin shall have a length of 2.0m, a width of 1.0m, and a depth of 1.5m, with its bottom compacted. A total of 89.57 × 104m3 topsoil used in the new soil grass of subgrade slope are stripped for the subgrade across the line.

3. Protective measures for Station

3.1 Station subgrade protection

The water and soil conservation measures for the station in this project is mainly aimed at

the station subgrade, which are roughly the same as the soil and water conservation

measures for the subgrade. Slope protection of arched frame pavement, hollow bricks with

new soil grass and mortar rubble drainage ditch and porous drain are used for the subgrade.

If the subgrade slope height is less than 3.0m, six-diamond hollow bricks with planted grass

and Amorpha will be used for protection, and a precast concrete drainage tank will located

at both sides of the slope at intervals of 10.0m to connect the horizontal drainage channels

between the tracks; if the slope height is greater than 3.0m, 3×3m C25 concrete arch

framework with water disconnection tank will be used in the slope protection of the

subgrade, and in the framework, six-diamond hollow bricks will be paved with planted grass

and Amorpha. A layer of two-way stretch plastic geogrid (TGSG30-30) will be laid every

0.6m of the vertical height from the foot of the slope to the surface level of the base bed

within the lateral width of 3.0m on both sides of the slope; if the subgrade is filled with weak

weathered and slightly weathered broken rocks, the quantity of new soil shall be added into

the block.

The cutting slope rate shall be 1:1.25~1:1.5 for silty clay, 1:1.25 for gravel soil, and 1:1.25 for loess cutting. For the slope whose height is less than 3.0m, six-diamond hollow bricks with planted grass and Amorpha inside shall be used for protection; for the slope whose height is greater than 3.0m, C25 concrete arch frame paved with six-diamond hollow bricks with planted grass and Amorpha inside shall be used for protection. The stations are open-train layout, and the new sites are ground stations except that Huai An Station is an elevated one. The average earthwork height in plains is h≤ 3m (Huan An Station), 3m <h ≤ 5m (Ulanchabu Station), and in hilly area is 5m <h ≤ 7m (Xingheibei Station). Full sloping dry stone revetment is used for the slope protection of Xinghe Station and Ulanchabu Station, which is not included in the soil and water conservation engineering measures.

3.2 Greening measures in the station area

There are three new stations across the line, with Trunk of treesozi Station and Trunk of treesozi East Station under the construction being integrated for locations. In order to maintain soil and water and beautify the station area environment, to improve ecological environment quality of the station area, and to meet the production and operating conditions, 20% of the new permanent site in the station are greened in line with the principle of multiple green. They are mainly located at the surrounding of the new buildings at each station and other open space available for concentrated green. Trees, shrubs, flowering shrubs and grass are integrated, in a green ratio of 30% by trees, shrubs 30%, flowering shrub 20%, and grass 20%, laid according to the principle of 3×3m for trees and 1 × 1m for shrubs. In the new stations, as Huai An Station is an elevated one, green design is considered for its areas available for green at the roads in the stops. The proportion of shrubs, flowering shrubs and lawns is 30%, 30% and 40% respectively. The shrubs are laid in 1× 1m. A total of 3,523 trees, 34,898 shrubs, 9,532 flowers and 4,958m2 paved turf are planted in the stations across the line.

3.3 Temporary block protection and temporary drainage measures for stripped topsoil in the station area22.25 × 104m3 stripped topsoil in the new stations across the line is used for the latter stage

green in the station. The stripped topsoil will be designed to be piled in the temporary

stockpiling site in the station area, and they will be compacted. Retaining wall made of straw

bags will be used as temporary protection at the foot of the outside slope surrounding the

stockpiled soil, and other exposed surfaces will be covered with tarpaulin. Temporary drains

will be dug at the border of the stockpile soil, temporary settling basin will be constructed at

the outlet of the drains, and connected with the surrounding drainage system.

The stockpiling height of the temporary stockpiling filed shall not be higher than 3.0m, and

the stacked slope rate shall be controlled within 1:1.5. The straw bag retaining wall section

4. Control Measures in the Bridge and Culvert Works Area

4.1 Bridges and culverts set-up and design requirementsThe flood frequency of bridges and culverts is designed to be 1/100 for bridges, and 1/100

for culverts. In principle, one bridge (culvert) is set up for one river (ditch), and the river

channel shall not be compressed, so that the water may go through the bridge in a natural

state; where roads are crossing, interchange may be used; in the farming-intensive areas,

farmland channel shall be located; vertical drains shall be located within the bridge, and

connected with the drainage system in the subgrade so as to lead to the water in the side

ditches of the subgrade to the natural ditches under the bridge. M10 mortar rubble paving

protection shall be adopted.

Permeable soil shall be used to fill the cone packing of the bridge ancillary works and be

compacted, and 35cm thick M20 mortar rubble shall be used in the protection of slope with

a 10cm thick gravel layer located below.

For individual lots where river erosion may be increased due to the set-up of piers,

reinforced subgrade and mortar rubble revetment measures shall be taken to avoid the

river, flood erosion. The bridge foundation excavation shall be made full use of; if it is unable

to use, spoil field shall be selected for concentrated spoil to reduce soil erosion.

The foundation of the main pier crossing the river shall use island or cofferdam construction

and shall avoid flood. Complete cleanup shall be considered after the construction to ensure

the smooth water flow.

4.2 Bridge and culvert protective measures

(1) The flood frequency of 1/100 is used in the design of the bridge and culvert to

maintain the appropriate technical requirements; for the check calculation of extra large

bridge (or large bridge) which is technically complex, difficult to repair or very important,

the flood frequency is 1/300; for the bridge close to the upstream reservoir, check

calculation will be made according to the reservoir dam break flow.

(2) Natural river channel shall be avoided from compress and ditches from change when

crossing the river channel for flood discharge so as to maintain the natural run-off state and

to ensure smooth flow of flood discharge. Streamlined piers shall preferably be used in the

river channel to reduce the water-blocking area of the pier, and avoid increased erosion, as

well as to reduce the impact on the upstream and downstream slopes of the bridge site and

to avoid soil erosion.

(3) Flood discharging capacity is fully considered in the design of the diameter of the

culvert to avoid the water restrain of the culvert caused by the small aperture, resulting in

soil erosion caused by increased downstream erosion.

(4) For the pier located in the ditch or in the water, cofferdam made of straw bags filled

with soil or steel sheet pile cofferdam is used based on the water depth in the construction

and geological conditions, and the protection of the sections where the water level is high

and the foundation layer is strongly permeable shall be paid attention to in the construction.

(5) During the construction, the spoil generated in the bridge foundation construction

shall be knocked into the pile foundation if permitted by conditions; abutment cone slope

shall be protected by M20 cement mortar rubble.

4.3 Temporary protection measures for bridge and viaduct

(1) Temporary measures to deal with bored pile foundation mud for the bridge

To minimize the pollution of the water quality of the rivers along the line by the bridge

drilling mud, bored pile foundation of the bridge crossing river is usually constructed during

the dry season, and mud pump is installed in steel casing barrel to raise the drilling mud to

the land TWA at both ends. The slurry generated during the bored pile foundation

construction shall be temporarily processed to reduce soil erosion during construction.

There are a total of two bridges which cross a river and possess piers in the water in this

project. They are the extra large Yanghe Bridge and extra large No. 4 Daheihe Bridge. Before

the drilling of the piers, one mud pool (seepage control shall be done to the mud pond, and

multiple drilling can be shared) and two settling tanks are built in the temporary

construction site. They are used in series to make the wall protection mud separate from the

ballast. The mud precipitated shall be recycled, and the surface dust and ballast of the

sedimentation tanks shall be dehydrated at the dumping ground. The effluent of the

sedimentation tank discharges into natural rivers through the nearby agricultural irrigation

ditches. During the drilling and the hole cleaning in the pier foundation construction process,

mud cars are used to transport the mud to the designated location. The excavation earth

from mud pools and the sedimentation pond is piled near the pier and compacted. It will be

used in the pier foundation and the backfill of the mud pools and the sedimentation tanks

after the construction.

The volume of each mud pool is designed to be 8m3, and the length, width and depth to be

2m. The volume of each sedimentation tank is designed to be 6m3, the length and width 2m,

and the depth 1.5m.

(2) Temporary block and protection measures for excavation stone earth of the

foundation for bridges and culverts

Soil erosion is likely to occur for the excavation earth of the bridge foundation in the rainy or

windy season. Temporary block and protection measures shall be taken to prevent soil

erosion in the construction process.

After the balance of the excavation earthwork in the bridge foundation along the line in the

project, abandoned earth of 79.00 × 104m3 are resulted. Temporary stockpiling field shall be

set up in the land of the bridge. The temporary stockpiling height shall not be higher than

3.0m, and the pile slope rate shall be controlled within 1:1.5. The straw retaining wall

section shall be set in the form of a rectangular trapezoidal cross-section with height ×top

width× bottom width = 1.0m × 0.5m × 1.5m, and during the piling, the straws shall engage

and lap each other, with the lap length not less than the length of 1/3 of the straw.

Temporary stockpiling soil shall be centralized and piled in straw block protection. After the

construction, timely backfill and clean up shall be made, and extra earth shall be abandoned

in time in the earth fetching field nearby so as to avoid new soil erosion caused by rainfall

runoff or wind erosion.

(3) Protection measures in the construction of water piers

According to the actual situation of the project, water piers shall be set up in the river for the

new bridge across the river. Cofferdam measures shall be taken accordingly for the

foundation in the water according to the river channel, water depth, flow rate and venues.

Straw cofferdam and steel sheet pile cofferdam shall be mainly used to build island in the

construction for the project, and the construction period shall be as far as possible in the dry

season. After the cofferdam is used to build an island in the river, the construction shall be

made in the island, and all waste ballast and waste water generated in the foundation

excavation shall be transported to shore through the island. They will not be leaked into the

river, and will not have a big impact on the water quality. When the construction is complete,

timely removal of the cofferdam shall be made, and all cofferdam facilities shall be

transported to the nearest designated spoil site for storage. They shall neither be dumped in

the river, nor flowed into the river downstream.

5. Control Measures in Tunnel Works Area

There are 25 new tunnels in a length of 59.66km built in this project. The new tunnels are

concentrated in the lots of mountainous and hilly areas. The longest tunnel is Dajianshan

Tunnel in a length of 15,390m. The excavation of these new tunnels seeks early hole, and to

avoid deep cutting or high slope so as to minimize the destruction of the mountain and to

prevent soil erosion.

If the tunnel is longer than 500m, dual-port tunneling will be generally used; if the tunnel

length is less than 500m, single-port tunneling will be generally used. For Grade Ⅳ swelling

rock lots, if the expansion of the rock is medium to strong and the rock is shallow buried, the

method of "temporary invert of three steps " will be used; if the expansion is medium to

strong, the method of " temporary lateral bracket of three steps" will be used; weak

expansion lots shall as far as possible use the "three-step method" to strengthen the lock pin

bolt, and to strengthen the monitoring of measurement, so as to reduce the temporary

support works. For the lots of GradeⅤexpansion rock, the shallow buried section shall adopt

the method of "temporary invert of three steps"; and the deep buried segment may adopt the

method of " temporary lateral bracket of three steps" to reduce the temporary support

works. The ultra-shallow, or seriously pressured lots or sections which have to go through

buildings that require protection shall adopt the method of "CRD"; collapsible loess sections

shall try to use open-cut method, and the lots which require covered tunneling shall use the

method of "CRD".

5.1 Tunnel body protection

Tunnel entrance shall be chosen to minimize the excavation height of the side invert slope to

reduce the excavation, and the destruction of land and vegetation. Top-down stratified

excavation and layered protection shall be taken during the hole earthwork construction. In

case of poor geological conditions, measures to stabilize the side slope and the invert slope

shall be taken. The tunnel waterproofing and drainage shall follow the principle of "the

combination of prevention, disconnection, discharge and block for local conditions and in

comprehensive management", if necessary, the principle of "block-based, limited discharge"

shall be taken. Appropriate control measures shall be taken according to the tunnel length,

weather conditions, the nature and degree of development of groundwater to protect the

ecological environment. Fully enclosed lining of tunnel entrances of soil, swelling rock (soil),

and schist formation is adopted for the protection of side invert slopes at the entrance; the

rest of the stone tunnels shall be protected at the entrances and within 2m of the foot of the

slope. 30cm thick M15 mortar rubble lining shall be used.

Drainage ditches shall be located at the tunnel roof, with the distance of the drainage ditches

from the stone at the top of the slop excavation line not less than 5m. The soil shall not be

less than 10m so as to intercept surface water so that it may be imported into the subgrade

drainage system, thus avoiding the formation of new erosion.

5.2 Tunnel spoil protection

The spoil of the new tunnels totals 958.12×104m3. The spoil field shall be selected to heap

the abandoned spoil based on the factors like topographical conditions near the tunnel along

the line and transport distance.

Retaining wall shall be located at the foot of the slope for the spoil field, and protected by

mortar rubble for the foundation. After the disposable ballast is carried out, reclamation and

afforestation shall be conducted, and waterproofing and drainage facilities shall be equipped

to prevent soil erosion, and reduce the impact from drop ballast on the surrounding

environment.

6. Control Measures in Earth-fetching Area

6.1 Earth-fetching field set-up and optimizations

The earth-fetching fields set up along the line are mainly for the earth fetching of subgrade

and station, and the main type of land is unused land. In the earth excavation works, in the

spirit of the principle of concentrated earth fetching, the construction shall be made in

accordance with the position of earth-fetching field designed. The expansion of the

excavation area is not allowed, and flayer earth is strictly prohibited. The 0~30cm surface of

the earth-fetching field is prohibited to be used as fill. The surface layer shall be cleared and

stacked before earth fetching, and when the earthwork is completed, then they shall be

backfilled to the earth pit. Excavator with a dump truck is used to fetch the earth layer by

layer. It is proposed that if the excavation of soil complies with the requirements of packing,

the slope rate shall be slowed down, and the earth excavation depth may be enhanced to

reduce the project disturbance area. After the completion of the earth fetching, the slope of

the earth field shall be cut in a gradient of 1:1.5, and the slope shall be slowed down to

facilitate construction operations in an economic and safe way in preventing collapse and

soil erosion. Clean, flatting, green and other necessary measures shall be taken. In the next

stage of design, each earth field is required to sign an agreement on fetching and abandoning

of soil with the local Land and Resources Bureau.

6.2 Earth fetching and protection principles

1) The centralized and close earth fetching shall be carried out, and the priority in the

use of the existing earth field shall be made.

2) The selection of the earth field location shall obtain the coordination of the local

government and the soil and water conservation authority. The locacation shall be

determined through the consultation in the unified planning of the soil and water

conservation department based on the local water resources, agricultural

development planning, and environmental construction plan.

3) For the sloping earth field, after earth fetching, the slope of the excavation area shall

be adjusted, the bottom shall be cleaned and leveled, and green measures of shrub

planting shall be taken.

4) For the earth field ready to restore planting, before earth fetching, the surface

mellow soil shall be pushed aside, and leveled back after earth fetching. Reasonable

temporary protective measures shall be taken according to the terrain of the

temporary dump.

6.3 Earth field slope cutting and drainage design

In the excavation and earth fetching, the expansion of the disturbance area shall be avoided,

and the lane in a width of 10m and a longitudinal slope rate of 1:5 shall be reserved for the

access of the earth fetching pit. The lane shall stay in the side facing the construction area,

and the slope rate shall take 1: 1.5. The slope shall be cut by half-dug and half-fill to the limit

of 1/ 2 of the excavation depth. The upper earth of cut slope shall be used to fill the lower

slope, and the fill slope shall be backfilled and compacted layer by layer. To intercept the

slope runoff, and protect the overhead slope formed during earth fetching from directly

impact of wind and water erosion, a retaining ridge in a height of 80cm and a top width of

50cm shall be built beyond the upper sloping shoulder of the earth field, and intercepting

drains shall be located at the outside close to the retaining ridge so that the runoff above the

top of the slope will be channeled to both sides, then discharged to the close ditches. The

intercepting ditch has a bottom width of 0.5m, a top width of 1.5m, and a depth of 0.6m. The

soil ditches of semi-filled and semi- dug section shall be adopted and interior wall shall be

compacted. Base gutters in a bottom width of 50cm, a depth of 50cm, and a top width of 1m

shall be located at 1m outside the foot of the slope. Soil ditches shall be used, and interior

wall shall be compacted. If the slope has two platforms, the platform shall be an invert slop

directing toward interior side, namely, the side of the second slope, so as to create

conditions for the casing and the drainage in the future. Meanwhile, drains shall be located in

the middle platform and the foot of the secondary slope to discharge the slope runoff. The

water in the drains in the middle platform will flow down to lead the rainfall runoff into

natural ditches or the existing drainage ditch system. The drains in the foot of the secondary

slope shall adopt the same design standard with drains at the bottom of the slope.

6.4 Plant protection measures in the earth field

After the fetching in the earth field is completed, and when the engineering measures such as

slope adjustment of excavation area, leveling and cleaning of the underside, casing (casing

source is the topsoil stripped before earth fetching, and the casing thickness is about 30cm),

appropriate plant protection measures shall be taken on the bottom of the fetching pit, side

slope and platform. Through the green initiatives of sowing grass seed, planting shrubs, and

conservation and management measures of watering, fertilizing, and soil moisture to ensure

seedling survival rate, the purposes of soil and water conservation and the erosion control

may be achieved. The shrub spacing is 1 × 1m.

A total of 121.00hm2 rehabilitation area will be adopted for the earth fields across the line,

270,000 shrubs will be planted, and 88.60hm2 grass seed will be spread.

6.5 Temporary protection measures of stripped topsoil in the earth field

Before the fetching in the earth field, the 0~30cm surface layer of mellow soil shall be

scooped and stacked within the earth field. No new temporary area shall be used. The

bottom of the stockpiled soil shall be protected with temporary straw. The surface of the

temporary stockpiling shall be smooth and compacted and covered with a tarp to prevent

the erosion of rain runoff. Temporary soil drains shall be set up around the foot of the

stockpiling slope, so that the water collected may be discharged into the existing drainage

system around to prevent the new soil erosion. After completion of the earth fetching, the

topsoil shall be backfilled and leveled to facilitate the reclamation and revegetation.

A total of 32.40×104m3 topsoil is stripped in the earth fields across the line, with the

temporary block retaining length of 12, 585m, the stripping topsoil covering tarpaulin of

129,600m2, temporary drains of 4401m3, and temporary settling basins of 33.

7. Disposal Sites

7.1 Earth disposal site

There are 18 earth disposal sites, total earth disposed will be 4320700m3, occupying

54.8hm2.

7.2 Tunnel spoils disposal site

There will be 52 spoil disposal sites, total spoils disposed will be 10726400m3, occupying

121.21hm2.

7.3 Design of retaining wall

On the principle of “Firstly retaining and then discarding and retaining by grading”, adopt

mortar flag stone gravity type retaining wall protection for spoil ground.

To decrease active earth pressure, inclined type is adopted for gravity type retaining wall

this time. When designed, height of retaining wall is 4 to 8m. When change occurs on height

of wall, rectigradation transition is adopted for size of wall body; slope ratio of wall back is

1:0.25; wall surface is paralleled with wall back. Retaining wall is adopted for retaining base

of ballast slope. Embedded depth of foundation is not lower than 2.0m. The part below

ground of wall body is made into step-form, to increase stability of wall body; basement is

made into reverse slope, to increase resisting overturning ability of wall body.

100 PVC pipe is embedded for retaining wall body and is used as escape hole, distance is φ

2m×2m. Intercepting ditch and drainage ditch is set at ballast top. Bottom part of ditch must

be backfilled densely. Set one settlement joint each 10m longitudinally for the ditch; width of

joint is 2~3cm. For earthy spoil, filtration bed of crushed stone with width of about 500mm

needs to be set behind wall to facilitate drainage and avoid elapse of fine soil in earth filling.

Set blind drain in the middle of wall body with bigger height.

7.4 Drainage design

Drainage shall be provided at the top and foot of the disposal sites in order to timely discharge

runoff to avoid soil erosion and threats to the retaining wall.

7.5 Design of spoil grounds leveling and earth backing

After spoil is completed, top part of spoil ballast should be leveled. To facilitate recovery of

vegetation, mature soil of certain thickness should be covered onto soil body and buffer top

after leveled; earth backing comes from stripped surface soil of spoil grounds.

7.6 Reclamation and greening design for spoil grounds

After site leveling and earth backing work is completed for spoil, through combining local

actual situation, adopt reclamation measure for spoil grounds occupying fallow land for the

project and adopt protection measure of grass planting and shrub planting for spoil grounds

occupying timberland and not using land.

7.7 Design of temporary retaining measure for stripped surface soil for

spoil grounds

For spoil grounds where vegetation recovery is to be made, before spoil, shovel mature soil

by about 0~30cm of surface and stack them within the scope of spoil grounds without newly

increasing occupied area. Temporary straw bag is adopted for retaining bottom part of

stacked soil. Level and compact surface of temporary stacked soil, use fabric for covering and

build drainage ditch for temporary soil and make rainfall runoff influx before make it be

successfully discharged into surrounding trench and other existing drainage system, to avoid

causing new soil and water erosion. After spoil project is completed, level soil body and

buffer, cover stripped surface soil, to facilitate land reclamation and greening.

8. Access Roads

Because of construction vehicles rolling, surface of construction detour is disturbed,

vegetation is being destroyed and soil and water erosion will be easily produced. Therefore,

we put forward following prevention and treatment measure and suggestions for

construction detour soil and water erosion:

(1) Fully use existing rural road and road as transportation road, decrease quantity and

length of newly built road. For newly built construction detour, reasonably plan strike

direction, length and width of construction detour, decrease disturbance scope on surface,

control soil and water erosion.

(2) When constructing construction detour, through combining relief and existing traffic

condition, we should set it through combining construction of incoming road and rural road

as possible. Adopt road building scheme with small influence of disturbing surface. Decrease

excavation and fill on large scale. Spoil ballast produced from construction detour should be

removed and used for being filled and be allocated and used. Spoil which cannot be allocated

should be discarded into centralized earth-fetching area of main project design.

(3) During building process of road, strengthen retaining measure for excavated

earthwork and slope and avoid entrance of soil and ballast into farmland, to avoid causing

soil and water erosion .

(4) Construction detour should be set within land expropriation scope of railway as

possible. Try to avoid crossing forestry grass land with high coverage rate of vegetation.

(5) Waste earthwork produced from developing construction detour must be timely

cleaned and unitively handled. Do not freely discard because it will provide loose soil source

to soil and water erosion. Strictly regulate drive route of vehicles during construction

process.

(6) After use of construction detour is completed, we should negotiate with local relative

departments according to actual situation. Try to make construction detour used locally and

make it further used as maintenance road of railway. For road which cannot be used, adopt

site control measures of cleaning and leveling according to concrete situation and adopt

plant protection measure of planting shrubs and spreading grass seed for restoration.

After construction is ended, the area needing to be cleaned and leveled is 46.27hm2 for

prevention and treatment of construction detour; the area spreading grass seed reaches

46.27hm2.

9. Prevention and Treatment Measure for Manufacturing and Living Area for

Construction

Because of influence of artificial activities at construction site and camp site, surface

vegetation and soil structure within land use scope of site and camp site will be easily

destroyed, and it will cause losing original soil and water conservation function. Therefore,

following protection measures should be adopted:

(1) When select address for construction site, under the premise meeting principle

of proximity, try to use surrounding idle site or uncropped soil. Build of manufacturing and

living houses at construction site, tools and stone material stacking and material processing

site and arrangement of all other temporary manufacturing and living facilities should be

guaranteed reasonable, tidy and orderly. Try to more use local existing place, avoid

occupying more land caused by casualness of temporary project building and avoid

damaging soil and water conservation function.

(2) Definitely set position and scope of construction site and camp site. Do not freely

expand scope during construction process and not freely change address. Avoid occupying

more land caused by fluidity of engineering construction and clarify environmental

protection responsibility of construction site.

(3) After construction is ended, temporary facilities built during construction

process should be handed to local government through combining opinion from local

government. Clean waste from construction site and camp site surface and carry out

necessary leveling. Adopt vegetation measure of spreading grass for ground which can be

greened and recover its soil and water conservation function.

After construction is ended, adopt cleaning and leveling measure for temporarily occupied

construction site and camp site for the project and involved area reaches 147.99hm2, the

area spreading grass seed is147.99hm2.
