CONSTRUCTING FOUNDATION CONCRETE PILE OF SOFT SOIL GROUND

摘要

A concrete pile for foundation work of the soft ground is provided to increase the density and strength of concrete by pouring concrete to a top pile provided with coupling grooves and coupling projections and applying rotary force to the top pile. The concrete pile for foundation work of the soft ground comprises a top pile(10) composed of a body molding frame(2) having many projections(1) to increase the binding strength of concrete against a top pile and a pile molding frame(3) unified on the lower part of the body molding frame, and provided with coupling grooves(11) and coupling projections(12) formed on the outer circumferential surface of the body molding frame to couple with adjacent top piles, and concrete(20) filled in the top pile and provided with a fixing groove(21) to insert a C-shaped clamp to support and fix concrete piles on the ground more strongly. Hereon a rotary roller is fixed to the outer circumferential surface of the top pile and rotated to rotate the top pile to make the concrete placed in the top pile adhered/compressed to an internal wall of the top pile by centrifugal force.
