FIELD: construction.
SUBSTANCE: method of pile submersion by pressing in includes insertion of a pile pressing plant into a working device, which is installed vertically and pressed in a clamping mechanism, the pile is submerged for the value of travel of the pressing mechanism hydraulic jack piston (up to 1.0 m), the pile is undone in the working device of the plant, stems of the pressing mechanism hydraulic jacks are raised to the upper position (idle running), the pile is again pressed, and the cycle is repeated again until the pile is submerged to the design depth. In layers of dense soils with soil resistance to submersion, exceeding the maximum force of the pressing plant as the minimum speed of submersion is achieved, the pile motion is periodically stopped due to reduction of pressing force to zero value, the pile is withdrawn from soil by the value equal to the length of its side, and then the pile is lowered to the previous level at the minimum pressing force, afterwards the pressing force is increased to the maximum value, and the pile is submerged by the made step of the process cycle of alternating pressing-withdrawal-pressing.
EFFECT: provision of reliability of a process of pile submersion by pressing method through guaranteed reach of a bearing layer via layers of dense soils.
