STEEL PIPE, STEEL PIPE STRUCTURE, AND CONSTRUCTION METHOD OF STEEL PIPE STRUCTURE
To provide a steel pipe, a steel pipe structure, and a construction method of steel pipe structure that can secure bearing capacity performance of pile by suppressing lowering proof stress of bearing ground while reducing press-in resistance in conducting press-in construction of a steel pipe rotated and/or fluctuated, and that can secure horizontal resistance by suppressing lowering horizontal ground spring of steel pipe peripheral surface.SOLUTION: A steel pipe 1 according to the present invention is the steel pipe 1 that is embedded within a ground while excavating the ground by being rotated and/or fluctuated, and includes cutout shape parts 3 at its tip. The cutout shape parts 3 have a function that excavates a ground and forms a circular excavation groove when the steel pipe 1 rotates.SELECTED DRAWING: Figure 1
【課題】回転及び／又は揺動させた鋼管の圧入施工時における圧入抵抗を低減しつつ、支持地盤の耐力低下を抑制して杭の支持力性能を確保するとともに、鋼管周面の水平地盤ばねの低下も抑制して水平抵抗も確保することができる鋼管、鋼管構造体、鋼管構造体の構築方法を提供する。【解決手段】本発明に係る鋼管１は、回転及び／又は揺動させて地盤を掘り進めながら地盤内に埋設される鋼管１であって、先端に切欠き形状部３を有し、切欠き形状部３は鋼管１が回転する際に地盤を掘削して円形の掘削溝を形成する機能を有することを特徴とするものである。【選択図】 図１
