STEEL PIPE PILE AND CONSTRUCTION METHOD FOR STEEL PIPE PILE
To prevent deformation during excavation to maintain a function of excavation bits.SOLUTION: A steel pipe pile (10) comprises: a steel pipe body (11); and plate-like excavation bits (12) that are attached on an end surface (11E) of the steel pipe body (11) at angles (θ1, θ2) to circumferential tangents of the steel pipe body (11). The excavation bit (12) includes at least one set of an inner bit (121) and an outer bit (122) having at least a partial overlap in the circumference direction of the steel pipe body (11).SELECTED DRAWING: Figure 1
【課題】掘削時の変形に対抗して掘削ビットの機能を維持する。【解決手段】鋼管本体（１１）と、鋼管本体（１１）の端面（１１Ｅ）に鋼管本体（１１）の周方向接線に対して角度（θ１，θ２）をもって取り付けられる板状の掘削ビット（１２）とを備える鋼管杭（１０）において、掘削ビット（１２）が、鋼管本体（１１）の周方向について少なくとも部分的な重なりを有する少なくとも１組の内側ビット（１２１）と外側ビット（１２２）とを含む。【選択図】図１
