ABSTRACT:
A pile assembly for supporting a structure after being driven into a soil stratum comprises a pile body having a hollow interior. Two or more slots extend through the pile body at two or more different elevations. A steel plate is positioned within each slot. When driven into the ground, a mandrel is inserted into the pile body and used to push an actuator downwardly which, in turn, forces the steel plates outwardly into the soil stratum.
