ABSTRACT:
Load bearing capacity of a pile which is driven into the ground to support any of various structures is markedly increased following an initial period of pile driving. The pile includes a hollow pipe having a lower end region with longitudinal grooves which extend upward from an earth piercing shoe at the base of the pipe. An expansive force is exerted on the lower end region after the initial pile driving to rupture the pipe at the grooves and to bend strips of the pipe material outward for a first distance. Further pile driving bends the strips further outward as downward motion of the strips is resisted by the rim of the shoe and by ground which underlies the strips. This enables use of shorter piles and reduces driving time.
