METHOD OF ARRANGING PILE FOUNDATIONS WITH WIDENING BY METHOD OF CRUSHING Russian patent published in 2017 - IPC E02D5/44 

FIELD: construction.

SUBSTANCE: method of arranging pile foundations, in which a hollow pile with a shank of a detachable tip inserted therein is immersed by the method of crushing into the soil to the design mark, its internal cavity is filled with plastic concrete grout. The top pile cap is fixed in the grillage, and then pressure is created in the pile cavity. Prior to the setting of the plastic concrete grout, a piston is inserted into the inner pile cavity, vertical compressive load transferring the pressure to the upper surface of the concrete grout is applied to it, the amount of the vertical compressive load being greater than the force of immersing the pile by the method of crushing.

EFFECT: reducing the cost, material consumption and time of foundation construction, reducing negative impacts on the soil of the foundation and structure of the building.
