PROBLEM TO BE SOLVED: To solve the problem that a strength that concrete or the like which is filled in the inside of a steel pipe pile or in between an H section steel pile and a boring hole holds is neglected. SOLUTION: A bottom cover (10) is welded to the lower end of a steel pipe pile (6). A reinforcement (8) is wound up on the whole peripheral face of the steel pipe pile (6) at every equivalent pitch and welded. The steel pipe pile (6) attached with a bottom cover (10) is hung by a winch or the like and erected in the boring hole (5). Mortar (7) or the like is filled into the inner/outer peripheries of the erected steel pipe pile (6). After curing of the filler, a steel pressurizing plate (11) having one size smaller inner diameter than the steel pipe pile (6) is put on the cured mortar (7) or the like and a bolt (14) or a nut (15) is fastened to pressurize from one side of the ground surface side.
