FIELD: construction.
SUBSTANCE: invention relates to construction and can be used during sinking of pile by vibration-rotation indentation with resistance of soil exceeding maximum force of indenting plant. Method of sinking of pile into soil consists in pile loading into indentation mechanism and its rigid fixation in clamping device, sinking of pile into soil by means of mechanism of pressing by stroke amount of its hydraulic cylinders rods, loosening of the pile in clamping device and lifting indentation mechanism at no-load at height of stroke of its hydraulic cylinders rods, further rigid fixation of pile and its sinking, at that, actions aimed at sinking of pile into soil are performed in cycles. Preliminarily on soil surface under pressing mechanism coaxially to sinking pile rotational oscillations vibrodriver should be installed with through central hole, which upon reaching of dense soil layer by pile after no-load of indentation mechanism should be lifted until nearest face of indentation mechanism, pile should be rigidly fixed in vibrodriver opening and its immersion sinking should be performed in vibration-rotation mode of indentation during action of torques till design depth.
EFFECT: technical result consists in improvement of reliability of pile sinking into soil at its resistance exceeding maximum force of indentation due to prevention of development in pile deformations dangerous to its body integrity.
