PILE HEAD ISOLATION STRUCTURE AND CONSTRUCTION METHOD THEREOF
To provide a pile head isolation structure and a construction method thereof that further enhance the integrity between a solidification member on which the isolation device is fixed and an existing pile, for suppressing rigid body rotation of the solidification member with respect to the existing pile even more effectively.SOLUTION: An existing pile 2 is fabricated beforehand that has a plurality of reinforcing anchor bolts 5 embedded in a top end portion of cylindrical outer shell concrete 4 disposed inside a steel pipe 3. In the construction process, the existing pile 2 is installed in a ground G and an inner void portion 2a at the pile head is filled with a solidification member 9 to make a top surface of the pile head smooth, at the same time embedding a plurality of vertical reinforcing bars 6 and a plurality of fixtures 8 in the solidification member 9, the vertical reinforcing bars being connected to a top end portion of each of the reinforcing anchor bolts 5 and the fixtures being laid out in a circumferential direction of the pile leaving an interval in between. Furthermore, an isolation device 13 mounted on the top surface of the pile head is fixed on the existing pile 2 through the plurality of fixtures 8.SELECTED DRAWING: Figure 1
【課題】免震装置が固定される固化部材と既製杭との一体性をより高めて、既製杭に対する固化部材の剛体回転をより効果的に抑制できる杭頭免震構造およびその構築方法を提供する。【解決手段】鋼管３の内側に配置した筒形状の外殻コンクリート４の上端部に複数本の補強用アンカーボルト５が埋設された既製杭２を製造しておく。施工工程では、既製杭２を地盤Ｇに打設し、杭頭部の内空部分２ａを固化部材９によって埋めて杭頭部の上面を平坦にし、かつ、それぞれの補強用アンカーボルト５の上端部に接続した複数本の縦補強筋６と、杭周方向に間隔をあけて配置した複数の固定具８とを固化部材９に埋設した状態にする。そして、杭頭部の上面に載置した免震装置１３を複数の固定具８を介して既製杭２に固定する。【選択図】図１
