REINFORCEMENT OF VERTICAL PILES MADE IN SOIL AND PERCEIVING INDENTATION LOADS Russian patent published in 2012 - IPC E02D5/52 

FIELD: construction.

SUBSTANCE: reinforcement of piles operating for indentation load and made in soil under conditions, where it is not possible to do reinforcement with a single reinforcement frame for the entire depth of reinforcement includes at least two separate serially installed sections of the reinforcement frame, joined ends of which are inserted into a connecting coupling, having the length of at least two diameters of joined frame elements and filled with hardening material during assembly. Sections of the reinforcement frame are sections of serially installed stout rods or sections of thick-walled pipes, ends of which in the joint area are perpendicular to the longitudinal axis of the reinforcement frame. Pipes are inserted into a connection coupling with submersion of sections that reinforce the well into the well, so that inside the connection coupling there is a joint of pipes of sections that reinforce a pile, and the space in the well is filled with a hardening material or sections that reinforce the pile are arranged at least from two serially installed volume reinforcement frames, longitudinal rods of which at the side of the joint are welded to sections of stout rods or sections of thick-walled pipes, which are placed in the connection coupling.

EFFECT: higher reliability of piles, reduction of material intensity.
