CONSTRUCTION METHOD OF SUPERSTRUCTURE ON WATER
To provide a construction method of a superstructure on water that can efficiently construct a superstructure without performing a work below precast concrete blocks installed on piles erected on a water bottom ground.SOLUTION: By arranging a plurality of divided members 10 provided with an insertion hole 12 in a line in a circumferential direction of a through hole 3, each of the divided members 10 is supported by supports 14 inserted into the insertion hole 12 so as to slide and rotate along a bottom surface of a precast concrete block 2. By sliding each of the divided members 10 from above the precast concrete block 2 toward an outer peripheral surface of a pile 40, an arc-shaped front end portion 11 of each of the divided members 10 is fitted externally onto an outer peripheral surface of the pile 40. A gap S between the outer peripheral surface of the pile 40 and an inner peripheral surface at the bottom of the through hole 3 of the precast concrete block 2 is sealed by the divided members 10.SELECTED DRAWING: Figure 11
【課題】水底地盤に立設された杭に設置したプレキャストコンクリートブロックの下方での作業を行わずに、効率的に上部工を構築できる水上の上部工の構築方法を提供する。【解決手段】挿通孔１２が設けられている複数の分割部材１０を、貫通孔３の周方向に並べて配設して、挿通孔１２に挿通されている支持具１４により、それぞれの分割部材１０がプレキャストコンクリートブロック２の底面に沿ってスライド移動および回転可能に支持された状態とし、プレキャストコンクリートブロック２の上から、それぞれの分割部材１０を杭４０の外周面に向けてスライド移動させて、それぞれの分割部材１０の円弧状の前端部１１を杭４０の外周面に外嵌めした状態にして、複数の分割部材１０により杭４０の外周面とプレキャストコンクリートブロック２の貫通孔３の下部の内周面との間のすき間Ｓを塞いだ状態にする。【選択図】図１１
