Automatic reciprocating type static pressure steel pipe pile machine

Abstract

The invention discloses an automatic reciprocating type static pressure steel pipe pile machine, which comprises an annular jack, wherein the annular jack is arranged on the outer cylindrical surface of a steel pipe pile in a sleeving way; the top of a cylinder body of the annular jack is fixedly provided with an upper part flange used for being connected with an anchor rod anchored on a concrete substrate; a lower part flange used for being connected with an annular steel pipe clamping device is fixedly arranged at the bottom of a piston of the annular jack; the inner cavity upper section of an outer steel ring arranged in the annular steel pipe clamping device connected under the lower part flange is a conical ring-shaped cavity section; at least two clamp sheets used for clamping a tile-shaped structure of the steel pipe pile are arranged in the conical ring-shaped cavity section; the outer side surface of the clamp sheets is of a conical structure matched with the conical ring-shaped cavity section; a clamp piece jacking device is arranged in the cylindrical cavity section of the outer steel ring positioned under the installing clamp piece. The automatic reciprocating type static pressure steel pipe pile machine solves the problems that an ordinary static pressure pile machine occupies a great space, and is difficult to be used in transformation reinforcement engineering; meanwhile, the automatic reciprocating type static pressure steel pipe pile machine well solves the problem of poor verticality of the pressure pile.

Description

technical field [0001] The invention relates to a static pressure pile driver equipment applicable to the field of engineering construction, in particular to an automatic reciprocating static pressure steel pipe pile driver which uses hydraulic static pressure to press steel pipe piles into foundations. Background technique [0002] Steel pipe piles and prefabricated reinforced concrete pipe piles are two common forms of foundation piles in engineering construction at present. Among them, steel pipe piles are widely used in reconstruction and reinforcement projects because of their lightness and convenience for welding. [0003] The equipment that presses steel pipe piles into the foundation through hydraulic static force is called static pressure steel pipe pile machine, and the equipment that hammers steel pipe piles through hydraulic hammering or gravity and kinetic energy is called pile driver. [0004] The static pressure pile machine currently on the market is a very ...

AI Technical Summary

Problems solved by technology

Under this kind of engineering background, the method of burying anchor rods on the existing structural foundation (usually reinforced concrete foundation) is often used to provide counter force for construction work, but the crane cannot enter the work site due to the narrow construction environment. Tall pile driver supports are also inaccessible
