FIELD: construction.
SUBSTANCE: in a screw pile comprising a tubular shaft connected with a working element, having cutting elements and a tip in the form of a truncated back taper, the working element is made in the form of a cylindrical end cutter from solid concrete with a reinforcement frame and cutting elements in the amount of two diametrally arranged and opposite plates with front cutting edges, plates are fixed on the reinforcement frame at the angle of 35-40° to the end surface of the cutter, at the same time the ratio of plate width to the outer diameter of the cutter makes from 0.15 to 0.2, and through channels are made above plates in the cylinder for discharge of the cut soil.
EFFECT: development of a screw pile with improved structural and building characteristics.
