Abstract
A method for forming a deep cast-in-place concrete pile in the earth extending to an excessive depth by driving a hollow metallic pipe member having a height to span a substantial fraction of the design depth of the completed pile into the ground for almost its full depth, coupling a connector and hollow tubular driving mandrel to the top of the pipe section, driving the mandrel to advance the pipe section to the design depth while concurrently gravity feeding flowable concrete into the mandrel and pipe member extending therebelow, and withdrawing the mandrel leaving a monolithic concrete pile column encased by the pipe member over its lower portion.
