構築方法。3. A slide base is slidably mounted on an upper portion of a saddle provided with a clamp for gripping an existing steel pipe pile at a lower portion, and is vertically movably provided at a front end of a mast erected on the slide base. In a method for constructing a steel pipe pile using a pile press-in / pull-out machine having a chuck rotatably provided on an arm, a clamp is held on an existing steel pipe pile to fix the pile press-in / pull-out machine, and a pair of opposed ridge connection portions is provided on the outer periphery. After the steel pipe pile having the above is sandwiched by the chuck and pressed while being rotated, the ridge connection portion is stopped at a position not interfering with the rotation of the ridge connection portion of the steel pipe pile to be press-fitted next, and then slid. After moving the base forward by one pitch of the steel pipe pile, holding a new steel pipe pile in the chuck, lowering the chuck while rotating it and press-fitting it to an appropriate depth, with the press-fit of the steel pipe pile temporarily stopped, Grabbed by the clamp at the front end After rotating the installed steel pipe pile and abutting the ridge connection part on the ridge connection part of the adjacent steel pipe pile at the rear part to determine the welding point between the ridge connection part and the steel pipe pile, After releasing the clamp that is gripping and raising the clamp together with the saddle to move forward, the clamp is lowered together with the saddle to grip the existing steel pipe pile, and the chuck is lowered again to move the steel pipe pile to the existing steel pipe pile. A method for constructing a steel pipe pile wall, which comprises press-fitting the same height as, and welding a welded portion determined by abutting a ridge connecting portion of the adjacent steel pipe pile.

A clamp for holding a plurality of steel pipe piles is vertically provided at a lower portion of a saddle, a slide base and a mast are provided at an upper portion thereof, and the arm is attached to a front portion of the mast and is rotatable at a tip of an arm. In the pile press-fitting / extracting machine including a chuck, a clamp provided at a front end portion of the clamps is rotatably formed.
