CONSTRUCTION METHOD FOR REINFORCING FOUNDATION GROUND USING PILES WITH EXTENDED HEAD AND EXTENDING DEVICE FOR PILES
The present invention relates to a construction method for reinforcing the pile foundation ground using a head-expanded pile and an expanding device for a head-expanded pile capable of preventing a lower slime from rising upward by closing a gap between the outer surface of a pile and the inner wall of the ground using an expanding device as an expanding body in the lower part of a pile body is expanded while being rotated and cut; and reinforcing the foundation ground of the pile by allowing the expanding device to be supported on the original ground in the outside of a bored hole such that the density of peripheral ground can be increased. The construction method for reinforcing the pile foundation ground using a head-expanded pile according to the present invention uses a head-expanded pile comprising a hollow pipe-shaped pile body and an expanding device coupled to the lower part of the pile body while the diameter is expanded. The construction method comprises: (a) a step of inserting the head-expanded pile in the ground; and (b) a step of closing a part or the whole of a space between the inner wall of the ground and the outer surface of the pile as the expanding body is expanded by inserting a compression body with a conical bottom in a connection member through an upper penetration hole of the expanding device to compress the rear end of a compression part of the expanding body while rotating the expanding body of the expanding device on a central shaft of the pile.
