ABSTRACT:
A method for forming a pile by driving a thin-walled pipe is disclosed. A closed-end thin-walled pipe is driven partially into the earth until firm bearing is reached. The partially driven pipe is partially filled with a concrete and the concrete is hardened. A mandrel is inserted into the partially-driven pipe to contact the hardened concrete, and the pipe is driven downwardly further by driving with the mandrel against the concrete until driving is complete. The completely-driven pipe is then cut off and further filled with concrete to the cut-off level. Excess pipe which has been cut off is used to make up further piles.
