Track panel type long sleeper embedded ballastless track and construction method thereof
The invention relates to the technical field of rail transit, in particular to a track panel type long sleeper embedded ballastless track and a construction method thereof. The ballastless track comprises a base plate and a cast-in-place roadbed slab arranged on the base plate, and a plurality of sleepers are embedded in the cast-in-place roadbed slab within the unit length; a sleeper track panelis formed among the sleepers through connecting mechanisms, steel rails and fastener systems are installed on the sleepers, the sleepers are connected into a whole through truss reinforcing steel barsto form a track panel type whole structure, track panel assembling and adjusting positioning on site are avoided, and due to the fact that the relative positions of the sleepers are adjusted in advance, when the sleeper track panel is buried in a cast-in-place roadbed slab, a plurality of sleepers can be in place only by one-time adjustment, so that the installation efficiency of the sleepers isgreatly improved, the construction period can be shortened, the cost can be reduced, and meanwhile, the integrity and durability of the ballastless track are further enhanced by the connecting mechanism for forming the track panel type sleepers.
本发明涉及轨道交通技术领域，具体涉及一种轨排式长枕埋入式无砟轨道及其施工方法，无砟轨道包括底座板以及设置在所述底座板上的现浇道床板，所述现浇道床板在单元长度内埋设有多根轨枕，多根所述轨枕之间通过连接机构形成轨枕轨排，所述轨枕上安装有钢轨和扣件系统，采用桁架钢筋将多根轨枕连接成整体，形成轨排式整体结构，避免了现场进行轨排组装及调整定位，由于已经预先调整好轨枕之间的相对位置，在将轨枕轨排埋设到现浇道床板中时，只需要进行一次调整就能实现多根轨枕就位，大幅度提高了轨枕的安装效率，能缩短工期并降低成本，同时，用于形成轨排式轨枕的连接机构进一步加强了无砟轨道的整体性和耐久性。
