SET PILE, ASSEMBLY METHOD OF COMPOSITE PILE AND IMMERSION METHOD THEREOF BY METHOD OF ROTARY DRILLING WITHOUT AXIAL LOAD ON UPPER END OF PILE Russian patent published in 2019 - IPC E02D5/52 

FIELD: construction.

SUBSTANCE: group of inventions relates to construction and can be used for construction of foundations, installation of any supports on open ground, in rooms and under water (piers, and so forth), as well as for reinforcement of bearing capacity of any steel screw piles by threading separate support elements on the pile shaft. Assembled pile is assembled of alternating bearing elements-blocks from reinforced concrete or from any other strong solid non-corrosive material in the form of volumetric geometrical figure with through hole of any profile in the centre of bases and ellipsoidal plates-flanges with an offset relative to the centre hole and having deformation edges of the flange in the form of a screw blade, installed on the axis of the rod, of any geometrical profile, on the end of which a rock-destructing tool is fixed, and fixed to rod by welding or any mechanical method, wherein first support element is ellipsoidal plate-flange, and last - reinforced flanging plate.

EFFECT: technical result consists in improvement of carrying capacity of screw piles, increased service life, reduced time of construction due to fast production of foundation due to simple design of composite pile, as well as delivery of pile components to installation place without using oversized equipment.
