METHOD OF ARRANGING DRIVEN PILE Russian patent published in 2018 - IPC E02D5/60 

FIELD: construction.

SUBSTANCE: method of arranging driven pile, in which a well informed by dipping into the ground of the casing string with a closed lower end to the spreading base layer of soil, fill the casing string with tight or loose material, remove the casing string, generate a broadened base in support of the base layer of soil, immerse the reinforced concrete pile with the penetration of its end into the broadened base. To form the well, a casing string with a self-opening tip is used, the immersion of which is carried out with penetration into the spreading base layer of soil. Filling the casing string is first carried out with a rigid ground material or a rigid concrete mix, and then with loose or rigid ground material. The non-extractable shell-tube, equipped with a rim-nozzle on its lower end, with its penetration into the bearing layer of soil, is penetrated into the ground outside the casing string coaxially with it. When removing the casing string with a self-extracting tip, the shell-tube is simultaneously filled with filling material located in the casing string, followed by immersion of the reinforced concrete pile into the filled shell-tube up and forming a broadened base and enlarged compacted area in base layer of soil in and with increasing density of filling material within the lateral surface of the submerged pile.

EFFECT: increased bearing capacity of pile and pile foundation, reliability of its construction, expansion of the field of application on ground conditions, increased efficiency as a whole.
