FIELD: construction of pile foundations in civil engineering. SUBSTANCE: installation comprises a casing pipe, a guide pipe installed coaxially therein and forming a space between said pipes for the delivery of friable mixture to the lower edge of the guide pipe, and a stamp with a drive. The latter is made in the form of a diesel-driven hammer. Secured rigidly to the upper part of the casing pipe is a support-loading platform. The holder of the diesel-driven hammer is fastened to said platform while the hammer piston is linked with the stamp by rigid rods interconnected by cross heads. The stamp is capable of reciprocating in the guide pipe. The lower edge of the casing pipe is positioned higher than the lower edge of the casing pipe. EFFECT: improved design. 8 dwg
