METHOD OF ARRANGING INJECTION PILE Russian patent published in 2017 - IPC E02D5/46 

FIELD: construction.

SUBSTANCE: method for arranging an injection pile, according to which the well arrangement is carried out without excavation by means of pressing an injector pipe with a conical tip consisting of a disk and cutting plates, with simultaneously cutting longitudinal grooves on the well walls and forming a gap between the walls of a well to be made and the injector pipe. After immersing the injector pipe to the design mark, a hardening grout is injected under pressure into it, filling the arranged well with the grout, the soil area around the well and below being compacted. An unperforated injector pipe with a cylindrical widening at the bottom, the ends of which are chamfered towards the injection tube, forming the upper and the lower cones, is pressed into the soil. After immersing to the design mark, the injector pipe is removed from the well, leaving a tip in the well. Injecting the hardening grout is carried out simultaneously with extracting the injector pipe, filling the well with the hardening grout bottom-up. The soil area around the well is compacted while pressing and removing the injection pipe from the well with the surfaces of the lower and the upper cones of the injector pipe widening, respectively. After extracting the injector pipe, a reinforcement framework is immersed into the hardening grout.

EFFECT: increasing the carrying capacity of the foundation, manufacturability of its production in weak soils.
