A.V. VESELOV(S PILE AND METHOD OF ITS CONSTRUCTION Russian patent published in 2015 - IPC E02D5/50 

FIELD: construction.

SUBSTANCE: invention can be used in designs of piles intended for the arrangement of pile foundations and methods of construction of such piles. The pile consists of one leading (1) and multiple line (2) pile elements of an identical length and broadenings (3) around the line (2) elements. The leading (1) and line (2) elements consist of cylindrical upper parts (5) with an identical diameter and of lower parts (6) in the form truncated cones. The leading (1) element is fitted with a tubular element (7) which is coaxially protruding from the upper base of its cylindrical part (5). The line (2) elements have internal longitudinal coaxial cylindrical channels (8) for the accommodation of a guiding pipe (9). For the construction of the pile a well which is pre-drilled in the ground is filled with a ground-cementing solution, then the leading pile element is lowered into it up down to the required depth. A portion of a cement-and-sand solution is added into the well, the first line pile element is lowered until its installation on the leading pile element. The second and the subsequent line pile elements are lowered into the well until installation on the previous line pile element with adding into the well of a portion of the cement-and-sand solution before lowering of each line pile element until the achievement of the required pile length.

EFFECT: pile and the method of its construction provide unification of lengths of the components of the pile body, increase of the level of the ground compaction at the construction of the piles, improvement of the adhesion of the pile surface with the surrounding ground and increase of the bearing area of the pile on the soil base due to the fabrication of the pile consisting of the leading and line pile elements of the identical length and broadenings from the cement-and-sand mix around the line pile elements.
