INCLINED PILE CONSTRUCTION METHOD

PROBLEM TO BE SOLVED: To provide an inclined pile construction method with which a plurality of kinds of inclined holders are not needed to be prepared, further, an inclined holder maximizing a diameter of an insertion hole is not needed to be used and moreover, processes are shortened.SOLUTION: While hanging one end of a rotary press-fitting device 5, a space 10 is formed under the device and while utilizing the space, a slope 11 is formed under the rotary press-fitting device. The slope is formed by turning a pair of holder units 71 which are wedge-shaped while making upper surfaces into slopes from the single-hung-side of the rotary press-fitting device to the same direction while setting front ends of both the holder units ahead, opening an inclined pile passing part corresponding to a dimension of an inclined pile 1 between both the holder units, and inserting the pair of holder units to a top face of a ground 3 at a lower side of the rotary press-fitting device. The rotary press-fitting device is then moved down onto the slope and the pile is rotationally press-fitted.
