ABSTRACT:
Apparatus for simultaneously driving two parallel pile members that function to raise and reposition building foundation structures. The apparatus consists of a foundation support member, a frame assembly removably attached to the foundation support member, and a hydraulic ram and pile gripping assembly supported within said frame assembly. Alternately, the apparatus consists of a founation support member, a pile gripping assembly and a hydraulic ram removably interconnected between said foundation support member and said pile gripping assembly. As the hydraulic ram is actuated, the pile gripping assembly grips the pile members upon the start of downward movement relative to the pile members and completion of the stroke drives the pile members into the earth to a predetermined point of resistance. The apparatus then functions to raise and reposition the foundation after which the foundation is held in place by the pile members.
