STEEL PIPE PILE, PRESS-FITTING METHOD OF THE SAME, AND STEEL PIPE PILE CONTINUOUS WALL
PROBLEM TO BE SOLVED: To satisfactorily press-fit a steel pipe pile into the ground by sufficiently reducing friction of an inner circumferential surface and an outer circumferential surface of the steel pipe pile using fluid material.SOLUTION: A steel pipe pile 10 has multiple inside/outside connection holes 11 formed in the peripheral surface. In a process of rotating and press-fitting the steel pipe pile into the ground, a portion of water ejected from an outlet e disposed in the inside or the outer circumferential surface side of the steel pipe pile 10 is made to flow to an opposite side peripheral surface of the steel pipe pile 10 through the inside/outside connection hole 11. Accordingly, the steel pipe pile 10 is rotated and press-fitted into the ground while an appropriate amount of water is made to flow on both sides of an inner circumferential surface and an outer circumferential surface of the steel pipe pile 10, respectively. Thereby, the steel pipe pile 10 can satisfactorily be rotated and press-fitted into the ground, while the friction due to the soil and sand working on the steel pipe pile 10 is reduced by water flow.SELECTED DRAWING: Figure 1
【課題】流体物により鋼管杭の内周面及び外周面の摩擦を十分に低減し、鋼管杭を地盤に良好に圧入する。【解決手段】その周面に複数の内外連絡孔１１が形成されている鋼管杭１０を地盤に回転圧入する過程で、鋼管杭１０の内部又は外周面側に配設されている吐出口ｅから吐出した水の一部が、内外連絡孔１１を通じて鋼管杭１０の逆側周面へ流動するので、鋼管杭１０の内周面と外周面の両面にそれぞれ適量の水を流しながら、鋼管杭１０を地盤に回転圧入させることで、鋼管杭１０に作用する土砂などによる摩擦を水流によって低減しつつ、鋼管杭１０を地盤に良好に回転圧入することを可能にした。【選択図】図１
