Abstract:
1. For supporting a foundation, a system for driving a pile into the ground using a drill, comprising: a first member having a first end and a second end, the first end connecting to the drill, the second end having a keyed protrusion; and a second member having an upper portion that includes a hollow pile adapted to receive the first member therein, a lower portion that includes one or more blades along a perimeter of the lower portion, the upper portion connected with the lower portion so as to provide a one-piece fabricated pile, each one of the one or more blades providing a load resisting mechanism though end bearing thereof, the one or more blades (1) configured to hold the pile into the ground, and (2) providing sufficient support for the pile to support a structural member, without one of grout or fluids for ground improvement, the second member having a keyed opening for receiving the keyed protrusion of the first member, the upper portion including a light grade material, the lower portion including a high grade material, the high grade material of the lower portion providing greater rigidity than the light grade material, and the keyed opening disposed in the high grade material of the lower portion so as to drive the one-piece fabricated pile from the lower portion during installation to avoid damage to low grade material of the upper portion of the one-piece fabricated pile with the keyed protrusion of the first member in a mating configuration with the keyed opening of the second member, with the first member in a non-mating configuration from the upper portion of the second member, to provide torque to solely the lower portion.
