公路30m箱梁预制施工方法探讨

Study of the Prefabricated Construction Methods of Highway 30m Box Girder

文章以广西河池市金城江五桥项目为例,通过改变箱梁内模结构,并采取相应砼浇筑顺序,从根本上解决了箱梁底板砼浇筑质量难以保证的问题,供其他类型梁体预制参考与借鉴。

With the example of Jinchengjiang No.5 Bridge in Hechi,Guangxi,the paper solves the quality problems in pouring concrete into box girder baseplates by changing the internal mold structure of box girder and the order of concrete pouring, for the reference of similar projects.
