Title: Pile foundation
Inventor: GALUSHKO VALENTINA ALEKSANDROV
IPC: E02D27/34
Filed: 1991-09-17
Granted: 1996-03-20
Abstract: FIELD: civil engineering. SUBSTANCE: pile foundation includes foundation mat, a pile, and cylindrical shell composed of three parts along the height. Lower and upper parts of the cylindrical shell are provided with vertical teeth facing each other. The teeth are made in the form of truncated pyramids. Middle part of the shell is multilayered along its height in the form of individual segments with vertical through flat grooves under the teeth connected with vertical pins on one side. Lateral surfaces of the adjacent through flat grooves are perpendicular to one another. Total length of the vertical teeth is equal to the height of the middle part of the shell. Soil sagging results in displacement of upper and lower parts together with the soil. This results in filling through flat grooves in the middle part with teeth of upper and lower parts. Segments become open in the soil under action of teeth, and screwed in to compress it, and to increase cavity between the pile and middle part of the shell. Incompressible material is fed to the shell through vertical grooves originated in external surface of the pile after stabilizing the soil completely. EFFECT: increased bearing capacity of the foundation at the expense of increased surface of the contact between the shell and soil, and at the expense of more strength link between the shell and the pile. 6 dwg, 1 tbl
