STEEL PIPE PILE, CONSTRUCTION METHOD OF STEEL PIPE PILE, AND BEARING POWER CONFIRMATION METHOD OF STEEL PIPE PILE
To provide a steel pipe pile capable of reducing an influence of an excess pore water pressure when confirming bearing power, a construction method of a steel pipe pile, and a bearing power confirmation method of a steel pipe pile.SOLUTION: A steel pipe pile 1 in which a blade is not formed on a pile peripheral surface for supporting a structure includes: a cylindrical steel pipe pile body 2 made of steel; and a tip closing plate 3 for closing a tip of the steel pipe pile body 2. At the tip closing plate 3, one or a plurality of excessive pore water dissipation holes 3a, 3a communicating with the inside of the steel pipe body 2 are bored, for dissipating the excess pore water pressure when confirming bearing power.SELECTED DRAWING: Figure 3
【課題】支持力を確認する際に過剰間隙水圧の影響を低減することができる鋼管杭、鋼管杭の施工方法、及び鋼管杭の支持力確認方法を提供する。【解決手段】構造物を支持する杭周面に翼が形成されていない鋼管杭１において、円筒状の鋼製の鋼管杭本体２と、この鋼管杭本体２の先端を閉塞する先端閉塞板３と、を備え、この先端閉塞板３に、支持力を確認する際の過剰間隙水圧を消散するための鋼管杭本体２の内部に連通する単数又は複数の過剰間隙水圧消散孔３ａ，３ａを穿設する。【選択図】図３
