Abstract:
A multi-section pile apparatus, comprising:a) a lowermost anchor that is configured to be driven into a soil mass by rotation, the anchor having a helically threaded portion; b) a plurality of pile sections that are connectable end-to-end at joints, the pipe sections and joints having hollow bores, a lowermost of the pile sections being connectable to the top of the anchor; c) an internal drive that fits inside of the pile sections, the drive including enlarged sections that snugly fit the bores of the joints between respective pile sections, each joint being occupied by an enlarged section of the drive; d) wherein the enlarged section and the joints are configured with non-annular surfaces that enable torque to be transmitted from the drive to the pile sections; e) the lower end portion of the drive having a connector that enables a connection to be made between the lower end portion of the drive and an upper end portion of the anchor; and f) the combination of pile sections and joints being continuously hollow so what fill material added to the uppermost pile section enables all of the pile sections to be filled with fill material.
