Key aims of Marais technologies
6
Continuous screening of the trench: the layer
• Keeps the geometrical features of the trench
• No material falling while the network is being laid
• No decompaction of the surrounding ground
• Quality of the trench bottom: the shoe
The mechanical laying with the Marais wheel: Advantages against a traditional laying process
Increase Work Quality

Key aims of Marais technologies
7
Laying quality of the network
• Constant depth; the wheel cuts both hard and soft materials
• Constant altimetry and planimetry during the laying of the network
• Compliance with the admissible bending radii all over the laying operation
• Compliance with the cover (constant load applied to the network)
The mechanical laying with the Marais wheel: Advantages against a traditional laying process
Increase Work Quality

Key aims of Marais technologies
Constant and reduced width of the trench
•Constant metric construction cost
•Less materials to be excavated
•Less materials to be backfilled and compacted
•Reduced repair of the surface

Chain trenchers
10
Deep trenches
• Machines dedicated to wide trenches opening
• All machines have a conveyer
• Easy reuse of the excavated materials
• Same machine in soft and hard soils
• Could be adapted to mechanical laying
• Control of the quality of the trench
