FIELD: construction.
SUBSTANCE: invention relates to the field of construction and can be used to strengthen shallow foundations of buildings and structures under construction as well as existing buildings and structures during their reconstruction and repair. In the method, the device for the manufacture of a bored tapered pile consists of successively connected rods with a central injection channel, joined by couplings, and a drilling device at the end of the lower rod. Said drilling device is made in the form of a drilling head, consisting of drop-down blades hinged at the end of the lower rod and having a helical profile, as well as openings for feeding the working solution.
EFFECT: technical result consists in increasing the bearing capacity due to the manufacture of a bored tapered pile.
