摘要： A method for casting a partially-reinforced concrete pile in the ground includes installing an elongate hollow tubular casing in a hole in the ground with an elongate portion of the hole extending downwardly beneath the lower end of the casing. Hardenable fluid concrete is conducted into the hole and casing so as to substantially fill the respective hollow cross-sections thereof. The concrete is permitted to reach a hardened state while the casing remains within the ground, thereby forming a concrete pile partially reinforced by the casing against side-loading in an upper portion of the pile.

摘要： A method for forming a pile by driving a thin-walled pipe is disclosed. A closed-end thin-walled pipe is driven partially into the earth until firm bearing is reached. The partially driven pipe is partially filled with a concrete and the concrete is hardened. A mandrel is inserted into the partially-driven pipe to contact the hardened concrete, and the pipe is driven downwardly further by driving with the mandrel against the concrete until driving is complete. The completely-driven pipe is then cut off and further filled with concrete to the cut-off level. Excess pipe which has been cut off is used to make up further piles.

摘要： An apparatus for forming an in-ground concrete piling includes an elongate hollow mandrel which can be driven into the ground with a pile driver. A cupped foot, having a larger cross-sectional area than the mandrel, is placed beneath the mandrel before it is driven into the ground, and openings located near the bottom of the mandrel permit grout placed in the mandrel to flow into the space between the mandrel and the foot. A hollow sheath which slidably fits over the foot is attached to the bottom of an annular collar which slidably fits over the mandrel, forming a seal to prevent escape of grout from the openings while the mandrel is being filled. In use the mandrel is filled with grout before it is driven into the ground. Thereafter, during driving, the grout flows out of the openings in the bottom of the mandrel into the space around the mandrel, which is created by the foot. The column of grout in the mandrel acts as a static pressure head which forces the grout out of the mandrel into the surrounding space with a high volumetric flow rate as fast as the space is created.
