复杂铁路站场内线路架空加固施工技术

摘要

结合贵港市解放路下穿铁路框架桥工程 D 型便梁架空加固运营铁路施工，介绍了复杂铁路站场内一次架空多股道、小半径曲线线路、道岔岔尾段和道岔整体架空等不同施工条件下的线路架空施工技术，重点对线路架空技术条件、实际做法和施工注意事项进行了阐述，希望为同类工程施工提供参考依据。%Combined with the construction of D-type movable beam overhead reinforcing the existing railway in the project of Jiefang Road,Guigang underpassing the railway frame bridge,this paper introduces the line overhead construction tech-nology for complex railway station yard under different conditions such as one-time overhead of multiple tracks,small radius curve lines,overall overhead of the turnout and its end,and focuses on explaining the technical requirements and actual practice of line overhead,and construction points for attention,hoping to provide a reference basis for the construction of similar engineering.
