HELICAL PILE HAVING STRUCTURE FOR PREVENTING BUCKLING, AND CONSTRUCTING METHOD THEREOF

摘要

The present invention relates to a helical pile having a structure to prevent buckling, which is provided to prevent buckling of a pile body due to overburden load which is loaded on the helical pile which supports a load from the ground by having the front end of the pile body inserted into the ground, wherein, rotary wings are provided on the front end of the pile body, and when the pile body rotates, the twisted shape of the rotary wings makes the front end of the pile body penetrate the ground, and is provided to improve the surface friction force and front end bearing power of the helical pile; and a construction method thereof. The construction method of the helical pile according to the present invention comprises: a step for vertically arranging a helical pile for the front end of the helical pile to face the ground; a step for installing a pile body and an outer casing in the ground by using a motor to rotate the pile body and the outer casing so that the front end penetrates the ground; and a step for forming a buckling reinforcing unit by placing concrete in a gap between the outer casing and the pile body.
