FIELD: construction.
SUBSTANCE: manufacturing method of an inclined pile with controlled widening involves drilling of a well, installation of a reinforcement framework in the form of a tube, injection of a cement-and-sand solution before controlled swaging of walls of the well throughout the length of annular space. The reinforcement framework is made in the form of an injection tube with two or three zones of injection holes and a rubber shell membrane fixed on its end. Injection holes are made with a diameter of 0.08-0.12d, where d - well diameter, and uniformly located in a staggered order in all zones; in the first zone - at the distance of 4-5d from the end, where the rubber shell membrane is fixed, and in the second and the third ones throughout the injection tube. Injection of the cement and sand solution is performed by means of a rubber hose, on the lower end of which a packer is located, and the upper end is connected to a pump station.
EFFECT: improving carrying capacity of a pile, its manufacturability and controllability of operating parameters.
