PILE HEAD STRUCTURE OF EXISTING PILE, AND PILE HEAD STRUCTURE OF EXISTING PILE AND NEW PILE
To provide a pile head structure of an existing pile, and a pile head structure of an existing pile and a new pile, in which a pile head of an existing pile bears a part of a vertical load of a newly constructed building while effectively suppressing an action of horizontal force during an earthquake.SOLUTION: In a pile head structure 90 of the existing pile, a pile top end surface 14 of an existing pile 10 and a concrete foundation 70 are separated, and there is a first gap 20 between an outer circumferential surface 15 of a pile head 12 of the existing pile 10 and a surrounding ground G. In a pile head structure 100 of an existing pile and a new pile in which the existing pile 10 and a new pile 10A support the concrete foundation 70, the pile top end surface 14 of the existing pile 10 and the concrete foundation 70 are separated, there is a first gap 20 between an outer circumferential surface 15 of a pile head 12 of the existing pile 10 and the surrounding ground G, and a pile head 13 of the new pile 10A is connected to the concrete foundation 70.SELECTED DRAWING: Figure 1A
【課題】既存杭の杭頭が、新設建築物の鉛直荷重の一部を負担しつつ、地震時の水平力が作用することを効果的に抑制されている、既存杭の杭頭構造と、既存杭と新設杭の杭頭構造を提供すること。【解決手段】既存杭の杭頭構造９０は、既存杭１０の杭天端面１４とコンクリート基礎７０とが縁切りされ、既存杭１０の杭頭１２の外周面１５と周辺地盤Ｇとの間に第１隙間２０がある。また、既存杭１０と新設杭１０Ａがコンクリート基礎７０を支持する、既存杭と新設杭の杭頭構造１００は、既存杭１０の杭天端面１４とコンクリート基礎７０とが縁切りされ、既存杭１０の杭頭１２の外周面１５と周辺地盤Ｇとの間に第１隙間２０があり、新設杭１０Ａの杭頭１３がコンクリート基礎７０に結合されている。【選択図】図１Ａ
