Overwater cast-in-place arch bridge supporting system and construction method thereof
The invention discloses an overwater cast-in-place arch bridge supporting system and a construction method thereof, and belongs to the field of building construction. The system comprises an arch-shaped net rack, two groups of cast-in-situ bored piles symmetrically arranged on the water bottom left and right, bearing platform foundations fixed to the tops of the cast-in-situ bored piles and abutments fixed to the upper surfaces of the bearing platform foundations. A support frame body is further fixed on the bearing platform foundation on the inner side of each abutment; the two ends of the arched net rack are fixed to the upper surfaces of the two symmetrical support frame bodies respectively, and the whole arched net rack covers the water surface between the two support frame bodies; at least two rows of symmetrical supporting bodies are vertically connected from the bottom surface of the arched net rack to the water bottom; the supporting body comprises a supporting combined frame body, a supporting platform and a steel pipe pile which are sequentially connected, and the bottom end of the steel pipe pile is inserted into the water bottom. According to the system, gravel soil does not need to be backfilled into water and a concrete cushion layer does not need to be poured so that an all-round scaffold and a construction platform can be conveniently erected, the system is environmentally friendly, the cast-in-place arch bridge supporting system can be efficiently erected, the labor amount is reduced, and the quality is guaranteed.
本发明公开了一种用于水上现浇拱桥支撑系统及其施工方法，属于建筑施工领域。本系统包括拱形网架、在水底左右对称设置的两组现浇灌注桩、固定于每组现浇灌注桩顶部的承台基础以及固定于承台基础上表面的墩台；在每个墩台内侧的承台基础上还固定有支座架体；拱形网架的两端分别固定于对称的两个支座架体上表面，整个拱形网架罩在两个支座架体之间的水面上；拱形网架底面至水底竖向连接有至少两排对称的支撑体；支撑体包括依次连接的支撑组合架体、支撑平台和钢管桩，钢管桩的底端插进水底。本系统无需往水中回填碎石土和浇筑混凝土垫层以便于搭设满堂脚手架和施工平台，环境友好，能更高效率地完成现浇拱桥支撑系统搭设，节约劳务用工量，保证质量。
