浅谈既有铁路升级改造中的无缝线路施工及封锁控制

Discussion on the Construction and blockage Control of Seamless Track in Upgrading and Rebuilding of Existing Railway

在国家铁路路网质量提升过程中,为满足线路提速的需要,普速既有铁路的改造施工任务大量增加,作为铁路既有线改造工程当中常使用的一项施工技术,无缝线路施工技术在施工工艺以及施工方案等方面有着相对特殊的要求。本文将通过具体工程实例,对既有铁路无缝线路改造工艺、方案、封锁安全管理控制作一简要阐述,以便相类似的工程借鉴。

In the process of improving the quality of the national railway network,in order to meet the need of increasing the speed of the railway line,the reconstruction and construction tasks of the existing railway lines have been greatly increased,as a construction technology often used in the existing railway line reconstruction projects.The construction technology of seamless track has relatively special requirements in construction technology and construction scheme.In this paper,through concrete engineering examples,the reconstruction technology,scheme,blockade safety management and control of the existing railway seamless track will be briefly described in order to draw lessons from similar projects.
