PROBLEM TO BE SOLVED: To provide a driving auxiliary tool of a steel pipe pile in which a supporting force higher than a capability of a steel pipe driver can be obtained.SOLUTION: A driving auxiliary tool of a steel pipe pile includes a driving auxiliary tool body 10 in which a weight for adding a vertical load can be mounted to a steel pipe pile W driven by the strike of a hammer of a steel pipe driver and the capability of the steel pipe driver can be assisted by the vertical load of the weight. The driving auxiliary tool body 10 includes: a placement part 12 having a slide contact surface 11 coming into slide contact with one side of the steel pipe pile W in the diameter direction, and placing a weight by projecting to the outside in the radial direction from the slide contact surface 11; and fixing means 13 for fixing the slide contact surface 11 while being press-contacted against the steel pipe pile W. The fixing means 13 includes: an arm part 14 extended to the other side in the diameter direction from one end of the slide contact surface 11 in the circumferential direction along the outer circumferential surface of the steel pipe pile W; a screw hole 15 penetrating to the radial direction of the steel pipe pile W in the tip part of the arm part 14; and a bolt member 16 screwed to the screw hole 15, and having the tip abutted with the other side in the diameter direction of an outer circumferential surface of the steel pipe pile W and bringing the slide contact surface 11 into press-contact with one side in the diameter direction of the outer circumferential surface of the steel pipe pile W.
【課題】鋼管杭打ち装置の能力以上の支持力を得ることができる鋼管杭の打ち込み補助具を提供する。【解決手段】鋼管杭打ち装置のハンマの打撃により打ち込まれる鋼管杭Ｗに対し鉛直荷重を付加する錘を装着可能とし、錘の鉛直荷重によって鋼管杭打ち装置の能力を補助する打ち込み補助具本体１０を備える。打ち込み補助具本体１０に、鋼管杭Ｗの直径方向一側に摺接する摺接面１１を有し、かつ摺接面１１より半径方向外方側へ突出して錘を載置する載置部１２と、摺接面１１を鋼管杭Ｗに圧接させた状態で固定する固定手段１３とを備える。固定手段１３に、摺接面１１の周方向一端より鋼管杭Ｗの外周面に沿って直径方向他側に延びる腕部１４と、腕部１４の先端部において鋼管杭Ｗの半径方向に貫通するねじ孔１５と、ねじ孔１５に螺着され、先端が鋼管杭Ｗの外周面の直径方向他側に当接して摺接面１１を鋼管杭Ｗの外周面の直径方向一側に圧接させるボルト部材１６とを備える。【選択図】図２
