Initial situation Natural Gas pipeline installed involving clearing of slopes and covering a 20 intransmission line. The two slopes detailed on this project needed stabilizing toprotect the integrity of the transmission line, personal property and the publicfrom a slope failure. The solution required a cost effective system that couldmeet site challenges and provide safe, eco friendly slopes.
The nailed (anchored) TECCO® System effectively stabilized the slopes protectingthe integrity of the natural gas pipeline, property and the public. The revegetatedslope looks great and is eco-friendly. Grooming of the slope is not a problem andanimals can easily traverse the mitigated area.
Description The solution was 82 000 ft² of anchored TECCO® System utilizing TECCO® G65/3and P33/40 spike plates. Challenges for design and implementation includedaccess to the top of the slope. This was accomplished using a light weight,modular wagon drill for the top down TECCO® installation. The pipeline had to beconsidered during design with anchors strategically placed around the pipeline.Cathodic protection was ensured with properly grouted anchors and installingsleeves through the TECCO® mesh for wiring.
