STEEL PIPE PILE WITH SPIRAL BLADE, SOIL CEMENT COMBINATION PILE, AND CREATION METHOD THEREOF
To provide a soil-cement combination pile capable of maintaining integrity between steel pipe piles and soil-cement columns even when the displacement in the horizontal direction becomes large due to a relatively large horizontal force acting thereon.SOLUTION: A soil-cement combination pile P is formed by inserting a steel pipe pile with spiral blade 1, which has a steel pipe pile body 10 and one or more spiral blades 20 attached to the steel pipe pile body 10, into soil-cement pillar 2 created in ground G. An upward protrusion 22, which is protruding upward from the upper surface 21 of the spiral blade 20, is provided along the outer circumference of the spiral blade 20.SELECTED DRAWING: Figure 4
【課題】ソイルセメント合成杭に比較的大きな水平力が作用して水平方向における変位が大きくなっても、鋼管杭とソイルセメント柱体との一体性を維持する。【解決手段】ソイルセメント合成杭Ｐは、鋼管杭本体１０と鋼管杭本体１０に取り付けられた一つ以上の螺旋状羽根２０とを有する螺旋状羽根付鋼管杭１を、地盤Ｇ中に造成されるソイルセメント柱体２に挿入することにより形成したものであって、螺旋状羽根２０の上面２１から上方へと突出する上方突起２２を、螺旋状羽根２０の外周に沿って設ける。【選択図】図４
