CA 2468358

A pile is installed in a drilled hole in the ground by inserting a tube extending to the bottom and providing on the bottom end of the tube a bottom shoe for compressing material at the bottom of the hole. A drive tool attached to the upper end of the tube applies downward compression and reciprocating rotation forces to the tube. A hammer by-passes the drive tool to apply impact forces to an upper surface of the shoe at the bottom of the tube acting to drive the shoe in downward movement so that the shoe slides downwardly relative to the tube. A radial surface of the shoe causes compressive forces on the material at the bottom of the hole and blades on the radial surface when reciprocated back and forth by the tube cause break up of the compressed material to allow repeated compression and significantly increased supported loads on a pile which is applied with the tube removed and is supported on the shoe.
