Ballastless track structure with large displacement adjustment amount in tunnel
A ballastless track structure with a large displacement adjustment amount in a tunnel aims at achieving the large vertical adjustment amount of the track structure, has the adjustable capacity of accurate positioning and later maintenance, and can better adapt to deformation of an offline foundation. Comprising a track plate fixedly arranged on a tunnel inverted arch, two rows of sleeper blocks are transversely arranged on the track plate at intervals, the track plate is of a prefabricated frame type structure, and positioning grooves are formed in the positions of the sleeper blocks; the sleeper block is an independent prefabricated part, and the middle portion and the lower portion of a main body of the sleeper block are embedded in the positioning grooves in the track plate. The track plate and the sleeper block are detachably installed on the tunnel inverted arch through the connecting component, and the lower end of the connecting component is connected with the tunnel inverted arch in an anchoring mode.
一种隧道内大位移调整量无砟轨道结构，以实现轨道结构的垂向大调整量，且具有精准定位和后期维护的可调整能力，能更好地适应线下基础的变形。包括固定设置在隧道仰拱上的轨道板，轨道板上横向间隔设置有两列轨枕块，所述轨道板为预制框架式结构，在轨枕块位置处设置定位凹槽；所述轨枕块为独立的预制构件，其主体的中部及下部嵌套在轨道板上定位凹槽内。所述轨道板、轨枕块由连接构件可拆卸安装在隧道仰拱上，连接构件下端与隧道仰拱锚固连接。
