PILE, AND ITS ERECTION METHOD Russian patent published in 2015 - IPC E02D5/52 

FIELD: construction.

SUBSTANCE: pile having a shaft consisting of pile elements with protruding bars in their lower part. A shaft of pile elements is enveloped with an outer cover consisting of a layer of compacted soil with a soil-reinforcing additive. Each pile element has a cylindrical middle part, upper and lower parts in the form of flattened cones, the larger bases of which are represented with bases of the cylindrical part of the pile element; the smaller base of the upper cone is the upper base of the pile element, and the lower base of the lower cone is the lower base of the pile element. An inclination angle of a generatrix of the upper cone to the plane of its larger base is 45-60°. An inclination angle of a generatrix of the lower cone to the plane of its larger base is 65-75°. The lower base of the pile element is equipped with a cylindrical projection, the diameter of which is equal to diameter of the upper base of the pile element, and protruding bars, some ends of which are rigidly fixed in the body of the pile element in a circumferential direction around the cylindrical projection, and the other ones, which are bent to the outside at an angle relative to the axis of the pile element, are located in the outer cover of the pile.

EFFECT: increasing carrying capacity, reducing material consumption and labour intensity.
