FIELD: construction.
SUBSTANCE: device for formation of wells in soil by the method of piercing comprises a hollow working tip of conical shape fixed on the front end of a pressure rod in direction of piercing and a feeding mechanism. In the wall of the hollow working tip there are holes, and on its outer surface there is an elastic impermeable shell fixed to the top and the base of the working tip. The inner cavity of the working tip is tightly connected to the hollow pressure rod, the other end of which is connected with a source of pulsating liquid or gas.
