Fabricated ballastless track based on dry connection and construction method thereof
The invention relates to the technical field of railway tracks. According to the fabricated ballastless track based on dry connection and the construction method of the fabricated ballastless track, on-site pouring amount is reduced on the premise that precision is guaranteed, track laying efficiency is improved, and carbon emission is reduced. According to the technical scheme, the fabricated ballastless track based on dry connection is characterized by comprising a base layer, prefabricated units fixed to the base layer and longitudinally connected, and rails fixed to the prefabricated units; each prefabricated unit comprises a track plate, a vibration reduction rubber cushion layer, an isolation layer and a base plate which are sequentially arranged from top to bottom. The base plate is fixed on a base layer through a positioning anchor rod; the track plates are fixed to the base plate through the limiting check blocks, and every two adjacent track plates are in longitudinal weak connection through the anchoring limiting stoppers. The limiting check blocks are fixed to the side face of the track plate through the transverse limiting anchor rods and fixed to the top face of the base plate through the vertical limiting anchor rods. A rail bearing table is arranged on the top face of the rail plate.
本发明涉及一种铁路轨道技术领域。目的是提供一种基于干式连接的装配式无砟轨道及其施工方法，以实现在保障精度的前提下减少现场浇筑量，提升铺轨效率，降低碳排放。技术方案是：一种基于干式连接的装配式无砟轨道，其特征在于：该无砟轨道包括基层、固定在基层上且纵向连接的预制单元、固定在预制单元上的铁轨；所述预制单元包括由上而下依次设置的轨道板、减振橡胶垫层、隔离层、底座板；所述底座板通过定位锚杆固定在基层上；所述轨道板通过限位挡块固定在底座板上，相邻两个轨道板之间通过锚固限位器实现纵向弱连接；所述限位挡块通过横向限位锚杆与轨道板侧面固定并且通过垂向限位锚杆与底座板顶面固定；所述轨道板的顶面设有承轨台。
