PIPE CONCRETE PILE WITH REINFORCED BASE AND METHOD OF ITS ERECTION Russian patent published in 2013 - IPC E02D5/38 

FIELD: construction.

SUBSTANCE: pipe concrete pile with a reinforced base comprises an outer metal shell in the form of a pipe with a reinforcement frame made of longitudinal reinforcement rods arranged along the shell contour, filled with concrete. The outer metal pipe shell is made as non-extracted. The pipe-concrete pile additionally comprises a reinforcing element formed from an inner pile, made of a cylindrical part and a driven tip in the form of a truncated cone, and an expansion element formed from a concrete structure of cylindrical shape, divided into segments with the possibility of their displacement in radial direction with a rotation around the horizontal axis, and combined in a mounting position with an inner pile. The inner diameter in the upper part of the expansion element is more than the inner diameter in the lower part.

EFFECT: reduced material intensity and labour intensiveness, higher manufacturability and reliability of design.
