ABSTRACT:
The specification discloses a in situ cased pile and method for constructing same under the footing of a building. The invention is particularly suited to the stabilization of building footings in regions of unstable soil subject to uplift or subsistence. The cased pile extends through the unstable soil to a region of stable soil, and rests thereon. An enlarged pile footing in the stable soil is used. The movement of the unstable soil is isolated from the pile by means of a casing or tubular sleeve which surrounds the casing. A method of forming this structure in situ, without removing the unstable soil, is also disclosed. In the practice of this method a self-propelled soil displacing mole forms a hole in the subsoil and draws down a steel tube (15) to line the hole. The mole is withdrawn, a PVC or cardboard tube (16) is slid down the lined hole, and the lined hole is filled with concrete. The mole is re-run to produce a pile footing (17) and is again withdrawn. The resulting in situ cased pile is thereby isolated from frictional engagement with the subsoil to avoid heave.
