PIPE RAMMING

Placement of steel casing under features such as highways and railroad tracks to carry water, sewer, irrigation lines.

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 used to push the spoils into the reception pit. Pipe diameters range from 200mm diameter and up to 4,000mm and with no limit on linear metres.

Advantages:

• Fast, effective clean out

• Several methods available

• Cuts down on set up time
