CONNECTED CONCRETE BLOCK BODY FOR ARCH BRIDGE STRUCTURE, AND DECK-TYPE ARCH BRIDGE
PROBLEM TO BE SOLVED: To provide an easy-to-convey versatile connected concrete block body for an arch bridge structure, which enables a lower block to be installed without sagging by coming off an arc of an arch, and which makes fracture and exfoliation hardly caused by contact between blocks.SOLUTION: In a connected concrete block body for an arch bridge structure, a plurality of arch-stone blocks are integrated together by being connected together by an embedded geogrid, and an opening condition of a clearance between at least the lower end block and the adjacent block can be adjusted by a restraining member.SELECTED DRAWING: Figure 1
【課題】 下端ブロックがアーチの円弧から外れて吊り下がることがなく据え置きでき、ブロック同士の接触による欠損、剥離が生じにくく、搬送が容易で汎用性の高いアーチ橋構造用の連接コンクリートブロック体を提供する。【解決手段】 複数の迫石ブロック同士を、埋設されたジオグリッドで連接して一体化し、少なくとも下端ブロックは隣接ブロックとの隙間の開き具合を拘束部材によって調整可能とした、アーチ橋構造用の連接コンクリートブロック体である。【選択図】 図１
