To provide an easily manufactured enlarged-bottom type steel pipe pile.SOLUTION: An enlarged-bottom type steel pipe pile 1 extends vertically. The enlarged-bottom type steel pipe pile 1 comprises: a circular steel pipe 2 extending vertically, having a pair of cutouts 2a at its lower end edge, and having a clearance hole 2b below; a wing member 3 which has a cylindrical body 31 having a bolt hole 31a corresponding to the clearance hole 2b and having an inner diameter larger than an outer diameter of the circular steel pipe 2, a steel bottom body 32 fixed to a lower end of the cylindrical body 31 by welding, a steel wing body 33 fixed to an outer periphery of the cylindrical body 31 by welding, and a steel material 34 stretched within the cylindrical body 31 and fixed to the cylindrical body 31 by welding, in which both ends of the steel material 34 are arranged in each of the pair of cutouts 2a, and which covers a lower end of the circular steel pipe 2 so that the bolt hole 31a corresponds to the clearance hole 2b; and a bolt 4 screwed into the bolt hole 31a and reaching the clearance hole 2b.SELECTED DRAWING: Figure 1
【課題】製造が容易な拡底型の鋼管杭を提供する。【解決手段】拡底型の鋼管杭１は、鉛直に延びている。この拡底型の鋼管杭１は、鉛直に延びていて、下端縁に一対の切欠き２ａを有していると共に、下方に馬鹿穴２ｂを有している円形鋼管２と、馬鹿穴２ｂに対応するボルト穴３１ａを有し、円形鋼管２の外形よりも大きい内径の筒体３１と、筒体３１の下端に溶接で固定されている鋼製の底体３２と、筒体３１の外周に溶接で固定されている鋼製の翼体３３と、筒体３１の中に掛け渡されて筒体３１の中に溶接で固定されている鋼材３４と、を有し、鋼材３４の両端が一対の切欠き２ａの各々に配置されると共に、ボルト穴３１ａが馬鹿穴２ｂに対応するように円形鋼管２の下端に被せられている翼部材３と、ボルト穴３１ａにねじ込まれて馬鹿穴２ｂに達しているボルト４と、を備えている。【選択図】図１
