PILE CONSTRUCTION METHOD BY MULTI SECTION SEGMENT PILE

A pile construction method with nonlinear section is provided to reinforce the ground economically and effectively and to repair and reinforce a lower foundation or a pre-installed structure by designing a high-priced pile reinforcement body more effectively. A pile construction method with nonlinear section comprises the steps of forming a perforated hole to the ground to the appointed depth using a small-sized drill machine and installing a casing(300) to the ground for preventing the breaking of soil inward the perforated hole, and inserting reinforcement bodies(400) of a pile having different sectional sizes according to the depth of the ground to the perforated hole, inserting a perforated pipe(500) to the inside of the casing on the ground and filling up the inside of the casing with a grouting material(600).
