![]() RLA – Richmond Line Alliance – Jan 2010 |
Trenchless crossing of three culverts/creeks in the rail corridor - 10 pipes at each crossing together with 6 ULXs (various pipe sizes & multipulls). The Directional Drill was set up 50m from the centre of each culvert and receive holes 50m the other side of the culvert; this was to avoid any site run off entering to water courses. The 100m distances utilised the full roll of PE pipe thus eliminating any wastage. 2 x 140mm PE Electrical Conduits Culvert crossing 100m, 4 x 125mm PE Electrical Conduits Culvert crossing 100m, 4 x 110mm PE Comms Conduits Culvert crossing 100m.
