STEEL PIPE PILE FOUNDATION
PROBLEM TO BE SOLVED: To provide a steel pipe pile foundation that prevents complication of construction work and that can obtain relatively high flexural strength near the ground even when constructed in soft ground.SOLUTION: A steel pipe pile foundation for soft ground includes a body part (11) that assumes a cylindrical shape and that has a spiral blade part (14) with a predetermined angle formed on an outer peripheral surface of a lower end. The steel pipe pile having a flange part (12) for connection of a utility pole provided at an upper end of the body part is buried in the soft ground. A compensation part (13), which comprises a cylindrical member (13A) larger in diameter than the body part and a plurality of wing-like connection pieces (13B) provided between an inner peripheral surface of the cylindrical member and an outer peripheral surface of the body part, is provided in an upper part of the body part and at a position lower by a predetermined distance than the flange part.
【課題】工事が複雑にならずかつ軟弱地盤に施工したとしても比較的大きな地際の曲げ耐力が得られる鋼管杭基礎を実現する。【解決手段】円筒状をなし下端部の外周面に所定の角度を有する螺旋状の羽根部（１４）が形成された本体部（１１）を備え、該本体部の上端に電柱接続用のフランジ部（１２）が設けられている鋼管製の杭を軟弱地盤に埋設してなる軟弱地盤用の鋼管杭基礎において、本体部の上部であってフランジ部から所定距離だけ下方の位置に、本体部の径よりも大きな径を有する円筒部材（１３Ａ）と、該円筒部材の内周面と前記本体部の外周面との間に設けられた複数の翼状連結片（１３Ｂ）とを備えた補償部（１３）を設けるようにした。【選択図】図１
