ERECTION METHOD OF DRIVEN PILE Russian patent published in 2015 - IPC E02D5/34 

FIELD: construction.

SUBSTANCE: oscillations are obtained by means of a vibrator installed on a column of a screw shell. Essence of the invention consists in the fact that an erection method of a driven pile, which involves formation of a well by rotation of the screw shell at its being loaded by pressure, compaction of the well walls at reverse rotation of the screw shell, supply of working material through the well head along outer surface of the screw shell at reverse rotation with further compaction of working material, removal of the screw shell at its being loaded by pressure by pulling the screw shell out of the well by compacted working material; before the working material is supplied, it is moistened till humidity is 27-32%, thus bringing its consistency to soft and plastic. A vibration mode is activated at reverse rotation of the screw shell.

EFFECT: increasing density of working material of a pile due to high-frequency oscillations.
