To provide a method for repairing steel pipe piles that can obtain sufficient strength by cutting the damaged section of an existing steel pipe pile, attaching a new steel pipe pile with the same diameter as that of the existing steel pipe pile by means of welding, and filling the inside of the steel pipe piles with a filler.SOLUTION: The method for repairing steel pipe piles includes the steps of: cutting a repair target section 9 of a steel pipe pile 1 that is installed in a water bottom ground; welding a new steel pipe pile 10 with the same diameter as that of the steel pipe pile 1 on the cut steel pipe pile 1 in a circumferential direction; draining water from inside of the steel pipe pile 1; and filling, with a filler, a filling space 21 between the steel pipe pile 1 and a small diameter pipe 11 fixed in the new steel pipe pile 10. The small diameter pipe 11 has at or around its lower end, a sealing section 14 that is provided so as to contact an inner peripheral surface of the steel pipe pile 1. The sealing section 14 divides an inside of the new steel pipe pile 10 and the steel pipe pile 1 into upper and lower sections and receives the filler.SELECTED DRAWING: Figure 3
【課題】既設の鋼管杭の損傷部分を切断し、径が同サイズの鋼管杭を溶接により新たに取り付けて内部に充填材を充填することで、充分な強度を得ることができる鋼管杭の補修方法を提供する。【解決手段】水底地盤に打設された鋼管杭１の補修対象部分９を切断する工程と、切断後の鋼管杭１に鋼管杭１と径サイズが同一である新規の鋼管杭１０を円周方向に溶接する工程と、鋼管杭１の内部を排水する工程と、鋼管杭１および新規の鋼管杭１０内に固定された小径管１１との間の充填空間２１に充填材を充填する工程と、を含み、小径管１１は、下端または下端の近傍において鋼管杭１の内周面に接するように設けられた止水部１４を有し、新規の鋼管杭１０および鋼管杭１の内部で止水部１４が上下を仕切りかつ充填材を受け止める。【選択図】図３
