CROSSING OF 11 KV UNDERGROUND

Amount

Excavation in hard/dense/loose soil beneath the railway track for inserting 150mm dia HDPE pipe for laying of 11KV 35sqmm cable for 50 meter distance by trenchless method at a depth of 3 meters below ground level upto the railways boundary both side at Air Force Station Jandwal. The method used for crossing the HDPE pipe under the railway track is by pushing method (Trenchless) by hydraulic jack or other trenchless method. After pushing the pipe the some length the soil is to be removed and the process is repeated often. The longitudinal alignment and the level of pipe have to be checked after each push if the pipe tends to lift up at jacks end while pushing it has to be rectified by shifting the jacks at bit below the central axis before applying further jack pressure. The force required to push the pipe should be applied gradually to avoid the heaving upto the earth (Embankment). The work will be done with horizontal pushing method. End of the pipe will be closed to make it water proof. It will be ensured that no storm or rain water enter the pipe.
