METHOD OF MANUFACTURING STEEL PIPE PILE WITH PROTRUSION ON INNER SURFACE, CONSTRUCTION METHOD FOR STEEL PIPE PILE, AND STEEL PIPE PILE WITH PROTRUSION ON INNER SURFACE
To enable a protrusion to be easily formed in an arbitrary position on an inner surface of a steel pipe after a foundation pile is driven on site.SOLUTION: A method of manufacturing a steel pipe pile with a protrusion on an inner surface includes the following steps of: forming a recessed groove part 21a on an inner surface 2a of a steel pipe 2 by extending the steel pipe 2 to the outside from the inside in a pipe diameter direction by press working; and attaching a protrusion member 4 to the recessed groove part 21a. The steel pipe 2 and the protrusion member 4 are simultaneously extended to the outside from the inside by press working so as to attach the protrusion member 4 to the inner surface 2a of the steel pipe 2.SELECTED DRAWING: Figure 1
【課題】現場にて基礎杭打設後に鋼管内面の任意の位置に容易に突起を形成することができる。【解決手段】鋼管２をプレス加工により管径方向の内側から外側に押し広げることで、鋼管２の内面２ａに凹溝部２１ａを形成する工程と、凹溝部２１ａに突起部材４を取り付ける工程と、を有し、鋼管２と突起部材４とを同時にプレス加工により内側から外側に押し広げることで、鋼管２の内面２ａに突起部材４を取り付けるようにした内面突起付き鋼管杭の製造方法を提供する。【選択図】図１
