FIELD: construction.
SUBSTANCE: invention relates to construction, particularly to construction of pile foundations. Screw pile includes shaft with tip at one end and functional head rigidly fixed on the other end, containing spiral sections. Pile shaft is made from metal strip, deformed throughout the length in the form of solid spiral. Pile tip is pointed on its end, which makes 45-60° and has tapered face at an angle of 45°. Submersible into soil part of the pile shaft is made with faces tapered at an angle from 20 to 80° to the axis of pile shaft.
EFFECT: technical result - reduction of pile material consumption, labour intensity and energy intensity of its production, higher reliability.
