COMPOSITE PILE, AND CONSTRUCTION METHOD FOR FORMING COMPOSITE PILE

摘要

PROBLEM TO BE SOLVED: To provide a core member capable of transmitting a load into a soil cement column body for achieving friction force between the soil cement column body and the ground.;SOLUTION: A pile core 3 of resin is inserted into the soil cement column body 2 to integrate the soil cement column body 2 with the pile core 3 of resin so as to smooth transmission of the load. The pile core 3 of resin is formed by integrating a straight pipe part 3c with a knot-or spiral-shaped blade 4. The blade is formed to be thicker on the root side than on the tip side, so that the load applied to this composite pile is smoothly transmitted through the pile core 3 of resin and the soil cement 2 to the ground to be dispersed. By utilizing waste plastic for material of the pile core 3 of resin, the device can be useful for promoting formation of a cyclic society.;COPYRIGHT: (C)2002,JPO
