PROBLEM TO BE SOLVED: To provide a steel pipe pile which can secure as great a force of skin friction (adhesion) as possible, which has high productivity, and which can secure high bending rigidity for a part requiring the bending rigidity.SOLUTION: A twisted steel pipe pile 1 made by twisting a round or square steel pipe is characterized in that a twist angle at a length interval twice larger in dimension than a pipe diameter is in the range of 90°-180°. A plurality of grout loading/unloading holes, which enable grout to be loaded into/unloaded from a central part space, are made in a pipe wall of an intermediate part of the twisted steel pipe pile 1.SELECTED DRAWING: Figure 1
【課題】極力大きな周面摩擦力（付着力）を確保でき、生産性が高く、また、曲げ剛性を必要とする部分には高い曲げ剛性を確保できる鋼管杭を提供する。【解決手段】丸又は角形の鋼管がねじり加工されたツイスト鋼管杭１であって、管径の２倍の長さ間隔におけるねじり角度が９０°〜１８０°であることを特徴とする。ツイスト鋼管杭１の中間部の管壁に、中心部空間に対するグラウトの出入れが可能は複数のグラウト出入れ孔があけられている。【選択図】図１
