Replacing and replacing construction method for ballastless track tunnel base structure
The invention provides a ballastless track tunnel base structure dismounting and replacing construction method which is used for overall dismounting and replacing of CRTS I type plate type, CRTS II type plate type, CRTS III type plate type, CRTS I type double-block type and sleeper embedded type non-operation track structure railway tunnel base structures. Lining pre-reinforcement is carried out, and drainage and cable relocation construction are carried out; rail breaking construction is conducted, then ballastless track plate uncovering construction and line overhead device installation construction are conducted, and a tunnel base structure and a base plate are dismantled and reconstructed; and removing the line overhead device, resetting the ballastless track plate, recovering the line, recovering the ditch cable trough, and accelerating the line.
本发明提出了一种无砟轨道隧道基底结构拆换施工方法，用于CRTSI型板式、CRTSⅡ型板式、CRTSⅢ型板式、CRTS I型双块式和长枕埋入式无作轨道结构铁路隧道基底结构整体拆换，所述方法包括：施工准备；进行衬砌预加固，进行排水与电缆迁改施工；进行断轨施工，之后进行无砟轨道板揭板与安装线路架空装置施工，进行隧道基底结构及底座板拆除和重构；对线路架空装置拆除与无砟轨道板复位、线路恢复、水沟电缆槽恢复、线路提速工序。
