PROBLEM TO BE SOLVED: To provide a steel pipe construction jig, a steel pipe construction apparatus, and a steel pipe construction method which, when a steel pipe pile with a helical blade formed at the outer periphery of a steel pipe to extend consecutively from its one end toward the other end is press-fitted into the ground fix the pile firmly.;SOLUTION: A steel pipe pile 10 has a steel pipe 12 and a helical blade 14 formed helically at the outer periphery of the steel pipe to extend consecutively from its one end toward the other end, and is revolved and press-fitted into the ground. The steel pipe construction jig has a shaking-stopper member 110 through which the steel pipe pile is put when press-fitted into the ground and, has a height 1.5 times or more the pitch of the helical blade, an inner diameter equal to or larger than the outer diameter of the helical blade, and a cylindrical inner wall surface 114 that comes in contact with or approach the front end of the helical blade when the steel pipe pile is put.;COPYRIGHT: (C)2011,JPO&INPIT
