FIELD: construction engineering. SUBSTANCE: in device, reduced consumption of compressed air is achieved because air distributor is located coaxially with membrane and this allowed for reducing length of compressed air supply lines. Device for sinking elongated articles into ground has two systems of passages for delivery and discharge of compressed air from pneumatic chamber. Inlet and outlet passages are located at both sides of movable bush and coaxially with bush. Discharge passages are made in membrane and are periodically closed by striking mass. EFFECT: higher efficiency. 5 cl, 4 dwg
