FIELD: construction.
SUBSTANCE: method to withdraw piles from water area soil includes withdrawal of piles mechanically. Piles are withdrawn with a hydraulic grip, which is installed on a vessel of catamaran type, in the nose part between frames, above the waterline. Ballast reservoirs are filled with water. The vessel is settled to the waterline. The pile is tightly gripped with the hydraulic grip. Water is pumped from ballast reservoirs, and the pile is withdrawn from soil as a result of higher vessel floatability.
EFFECT: reduced labour intensiveness and material intensity of works performance, improved method of piles withdrawal from water area soil.
