结合某联络线一块CRTS-Ⅰ型无砟轨道板换板施工作业实践,通过对施工作业技术和流程的提炼和总结,归纳出在单线桥上通过锯轨、搭建临时作业线路、利用轨道车与平板车拆解作业等关键技术实现轨道板更换。该技术可供区间正线换板参考,同时也可为高速铁路同类无砟轨道养护维修提供参考。 Combined with a CRTS-Ⅰ ballastless track plate replacement operation practice of a certain connecting line, through the refining and summarizing of the construction operation technology and process, it is concluded that by using a saw rail, building a temporary operation line, Flatbed truck dismantling operations and other key technologies to achieve orbital plate replacement. This technique can be used as a reference for changing the front of the section, as well as providing reference for the maintenance and repair of similar ballastless rails in high-speed railway.
