水上S形鱼腹式景观桥现浇施工技术

The Cast in Place Construction Technology of S Shaped Fishbelly Landscape Bridge above the Water

现代城市桥梁建设对其景观功能要求越来越高,鱼腹式结构因其造型独特、结构优美而被广泛采用,而修建于河道上的景观桥,为创造灵动的美感,往往被设计成优美的曲线,这都给施工单位提出了更高的技术要求。本文以清远市北江市区段南岸绿道工程水上S形鱼腹式景观桥的施工为依托,总结了水上复杂造型的桥梁的现浇施工技术,通过支架平台设计、清水混凝土钢模板设计与制作、模板支撑体系设计等技术成功实施了水上现浇连续景观桥,为类似工程的施工提供参考和借鉴。

As the higher requirements on landscape function of modem city bridge, Fishbelly structure is widely used due to its unique shape and graceful structural appearance. However, the design of the landscape bridge built above the river, which is often designed as beautiful curve for the creation of smart and dynamic, gives higher tech- nical requirements to the construction unit. In this paper, based on the construction of S shaped Fishbelly landscape bridge above the water in the green road and landscape engineering on the south bank of the Qingyuan, the corre- sponding cast in place construction technologies of the bridge with complex appearance above water are summa- rized. Through the design of the platform, the concrete steel formwork and the design of the mouldboard supporting system, the successful implementation of the continuous landscape bridge is achieved, which provides reference for similar engineering.
