Ballastless turnout insertion method for uninterrupted traveling
The invention relates to a ballastless turnout inserting method for uninterrupted traveling. According to the method, the existing operation line base plate is widened to be matched with the base plate inserted into the turnout, construction of the inserted turnout plate type ballastless track base plate can be completed under the condition that running is not interrupted, the influence on existing line operation is small, the safety risk is controllable, the constructability is high, and the engineering quality is good; existing operation line base plates do not need to be chiseled away in the whole construction process, meanwhile, the newly-inserted turnout track unit is the same as an existing operation line ballastless track unit, the existing line track structure is reserved as much as possible, the turnout inserting and laying construction cost is greatly saved, and the construction period is shortened; the inserted ballastless turnout adopts a factory prefabricated turnout plate, the on-site concrete pouring workload is greatly reduced, the construction time is saved, meanwhile, a self-compacting concrete layer under the plate adopts a quick-hardening early-strength material, and smooth passing of a train during skylight point time construction operation is guaranteed.
本发明涉及一种不间断行车的无砟道岔插入方法。本发明中通过帮宽既有运营线底座板，使之与插入道岔的底座板相匹配，可实现不中断行车条件下完成对插入道岔板式无砟轨道底座板的施工，对既有线运营影响较小、安全风险可控、施工性较强、工程质量有；本发明施工全过程无需凿除既有运营线底座板，同时新插入道岔轨道单元与既有运营线无砟轨道单元相同，最大可能保留既有线轨道结构，极大节省了插铺道岔施工成本，缩短了施工周期；本发明中插入的无砟道岔采用工厂预制道岔板，大幅度减少了现场混凝土浇筑工作量，节省了施工时间，同时板下自密实混凝土层采用快硬早强材料，保证了天窗点时间施工作业期间列车的顺利通行。
