CONNECTED CONCRETE BLOCK BODY FOR ARCH BRIDGE STRUCTURE, AND DECK-TYPE ARCH BRIDGE

摘要

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
