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. A steel plate is retained within each slot by returning bars. When driven into the ground, a mandrel is inserted into the pile body and used to push downwardly an inverted pyramidally shaped actuator which, in turn, forces the steel plates outwardly into the soil stratum, deforming the retainer bars which exert an upward pressure on the plates to maintain the plates against the upper edge of the slot.
