Pipe Ramming

Pipe Ramming is useful for pipe and casing installations under railways and roads in shallow depths, flowing sands, gravel or other areas where other methods may cause surface settling or heaving. Containing the spoil in the casing minimizes the potential for surface settlement. This process uses pneumatic percussive blows to drive the pipe through the ground.

The leading edge of the pipe is open and allows for less friction against the soil with a cutting shoe and lubrication, this directs the spoil into the pipe. The spoil is then removed by auger, compressed air or water jetting depending on the size of the casing.
