METHOD OF MANUFACTURING STEEL PIPE SHEET PILE
PROBLEM TO BE SOLVED: To provide a method of manufacturing a steel pipe sheet pile, which enables deformation of a spiral steel pipe to be suppressed when the steel pipe sheet pile is manufactured from the spiral steel pipe.SOLUTION: In a steel pipe sheet pile, a joint is attached to a spiral steel pipe in which a belt-like steel plate is spirally bent and in which width-direction edges of the adjacent steel plates are welded together. A method of manufacturing the steel pipe sheet pile includes a shot peening step of applying shot peening to the spiral steel pipe, and a joint attachment step of attaching the joint to the spiral steel pipe by welding after the shot peening step.
【課題】スパイラル鋼管を用いて鋼管矢板を製造する際に、スパイラル鋼管の変形を抑えることができる鋼管矢板の製造方法を提供する。【解決手段】帯状の鋼板が螺旋状に曲げ加工され、隣接する鋼板の幅方向の縁同士が溶接されてなるスパイラル鋼管に、継手を取り付けてなる鋼管矢板の製造方法であって、スパイラル鋼管にショットピーニングを行うショットピーニング工程と、ショットピーニング工程後に、継手をスパイラル鋼管に溶接して取り付ける継手取付工程と、を備える。【選択図】図６
