COMPLEX PILE WITH IMPROVED END BEARING CAPACITY AND PILING METHOD OF COMPLEX PILE USING THE SAME

摘要

The present invention relates to a composite pile having an enhanced end bearing capacity and a composite pile embedment method using the same. More specifically, a composite pile having an enhanced end bearing capacity comprises a shoe plate having a protruding unit, which is combined to the lower end and protrudes in the lower outer periphery toward the lower part; a reinforcing band, which is equipped in the lower part; a PC steel wire, which is combined to the shoe plate at the end on one side and is tensioned; a PHC pile where concrete is poured and cured; and an insertion pipe for being introduced into a bearing layer, which is formed to enhance an end bearing capacity by being combined to the end of the PHC pile in a way of being in contact with the outer surface of a protruding unit of the shoe plate and being inserted into the protruding unit, and by passing through slime, which remains in a boring hole by a light blow, and the bearing layer having a weakened force in the lower part of the boring hole and then being mounted on the bearing layer having a high solidity.
