既有铁路桥梁改建顶进施工道岔加固技术

Reinforcement Technology for the Jacking Construction Switch of Existing Railway Bridges Reconstruction

近年来,既有铁路桥涵新增或改扩建工程逐年增多,特别是铁路道岔加固及使用D型便梁条件受限的顶进工程。论文结合工程实例,详细阐述既有铁路桥梁改建顶进施工道岔加固技术的施工工艺,为相关工程提供参考。

In recent years, the number of new railway bridges and culverts has been increased or expanded, especially in the case of railway ballast reinforcement and the use of D-shaped beam conditions. Combined with the engineering example, the paper elaborates the construction technology of the jacking switch reinforcement technology for the existing railway bridge reconstruction, and provides reference for the related workers.
