顶进框构桥主要施工技术

文章通过顶进框构桥的施工,详细阐述了其施工流程、施工工艺和关键环节的质量控制,并明确了施工中应注意的事项。着重分析了滑板施工、后背墙分配梁施工、铁路既有线线路加固及顶进四个方面的施工方法,体现了顶进桥与现浇桥的优点:能够最大限度缩短铁路线路加固时间,提高了铁路运营效率,保证了行车安全。通过笔者亲身经历,深入浅出理论与实践相结合,具有很强的可操作性,为提高顶进框构桥施工水平提供了基础资料。

Main Construction Technology of Top Frame Bridge

Through the construction of top frame bridge, this paper described the construction process, construction techniques and critical aspects of quality control in detail, and cleared the precautions in construction, focused on analyzing the construction of the skateboard and the back wall distribution of beam, construction method of existing railway lines reinforcement and four aspects of jacking, reflecting the advantages of top frame bridge and cast bridge： can maximize the reinforcement time of railway line, increase operational efficiency of railway and ensure traffic safety. Through the experience of the author, the paper combined with the theory and practice, which have strong operational ability, and provide the basic data for improving the construction of top frame bridge.
