Placement of steel casing under geographic features such as freeways, canals and railroad tracks to carry water lines, sewer lines, irrigation lines, etc.
Pipe ramming is a two-stage technique for installing steel casings from a bore pit to a reception pit utilizing dynamic energy from a percussion hammer attached to the end of the pipe. A pneumatic device or “pig” is then used to push the spoils into the reception pit.
Pipe diameters range from 6” in diameter and up, and with no limit on linear feet.
