Impact Ramming

Definition - What does Impact Ramming mean?

Impact ramming is the trenchless method in which a pneumatic hammer attached to an open-ended casing is driven into the ground to create a bore. The cuttings of the hole are trapped within the casing and later removed once the drive is completed.

Impact ramming is also referred to as pipe ramming.

Trenchlesspedia explains Impact Ramming

In impact ramming, the length of pipe installed is limited only by the available space on site. In a limited space, sections of pipe can be fused immediately before installation. This method is commonly used under railways and road embankments with diameters of up to 1.4 meters. It is suitable for all soil conditions except solid rock. This method has limited steering and monitoring capabilities, and is best suited for pipes with little or no bends.
