FOUNDATION PILE, FOUNDATION STRUCTURE, STRUCTURAL BODY, AND INSTALLATION METHOD OF FOUNDATION PILE
To provide a foundation pile, a foundation structure, a structural body, and an installation method of a foundation pile, improving workability as well as strengthening pull-out resistance of the foundation pile.SOLUTION: A foundation pile 1 penetrated into the ground is provided. The foundation pile 1 is provided with a pipe-like inner pile body 2, a foundation consolidation part 3 formed at a tip part of the inner pile body 2, an outer pile body 4 having a diameter larger than that of the inner pile body 2 and a length shorter than that of the inner pile body 2, being concentrically arranged with the inner pile body 2, and a blade part 5 formed at a tip part of the outer pile body 4 and positioned at a higher position in the ground than that of the foundation consolidation part 3.SELECTED DRAWING: Figure 1
【課題】基礎杭の施工性を高めつつ、引き抜き抵抗をも高めた基礎杭、基礎構造、構造物および基礎杭の施工方法を提供する。【解決手段】地盤に貫入する基礎杭１が提供される。基礎杭１は、管状の内側杭本体２と、内側杭本体２の先端部に形成される根固め部３と、内側杭本体２よりも径が大きく、内側杭本体２よりも短く、かつ内側杭本体２と同心に配置される管状の外側杭本体４と、外側杭本体４の先端部に形成され、地盤中で根固め部３よりも浅い位置にある羽根部５とを備える。【選択図】図１
