摘要
以津保铁路大北环线金钟河特大桥跨既有铁路框架墩施工为例,介绍了在场地狭窄、管线复杂、运输繁忙的电气化铁路上、有限的天窗时间内等条件下架设钢横梁的施工技术方法,采取了有效的安装方法,为今后同类框架梁施工提供有益的借鉴。
Taking the frame pier construction of Jinbao Railway North Ring Jinzhonghe Super Large Bridge across the existing railway as an example, the paper introduces the construction technology method for erecting steel beams under conditions of narrow site, complex pipeline, heavy-duty electrified railway and limited sunroof time, and adopts the effective installation method to provide a useful reference for the construction of similar frame beams in the future.
