FIELD: construction.
SUBSTANCE: pile comprises a hollow tubular case with an open lower end and an expander attached to the outer wall of the tubular case. The expander is fixed at the level of the open lower end of the tubular case and is made in the form of a spatial curvilinear structure, the section of which with a geometric plane passing via the vertical axis of symmetry of the tubular case is a trapezoid with bases. All points of trapezoid bases lie on spatial surfaces formed by displacement of trapezoid bases along parametric curves.
EFFECT: provision of vertical submersion of a pile with account of its bearing capacity.
