Patent ID: 6848864

Claim:
A process of leveling a structure by installing interlocked segmented underpinning piles for supporting the structure upon the earth comprising the steps of: (a) driving a first concrete pile segment into unexcavated earth a desired distance from the structure, the first pile segment comprising: (i) upper and lower substantially flat surfaces, and a first central axis of rotation; (ii) a first connector embedded in the first pile segment, positioned along the first central axis of rotation, the first connector having a coil; (b) interlocking a second concrete pile segment with the first pile segment, the second pile segment comprising: (i) upper and lower substantially flat surfaces, and a second central axis of rotation; (ii) a second connector embedded in the second pile segment, positioned along the second central axis of rotation, and extending at least from the second pile segment's upper surface to the lower surface, the second connector having a coil, a rod, and a plurality of bars, the plurality of bars connecting the coil and the rod; (c) wherein during step “b” the second connector engages the first connector by rotating the second pile segment around the second central axis of rotation until the lower surface of the second pile segment contacts the upper surface of the first pile segment; and (d) driving the second pile segment a desired distance into the earth.
