The invention discloses a longitudinal connection assembly type ballastless track structure and a construction method, and belongs to the field of ballastless tracks. The ballastless track structure comprises a plurality of unit plate modules, a plurality of leveling layers and a track bottom foundation. Each unit plate module comprises a prefabricated unit plate and a plurality of embedded steel pipes, the two ends of each embedded steel pipe extend out of the corresponding prefabricated unit plate, the corresponding embedded steel pipes between any two adjacent unit plate modules are fixedly connected and communicated, and grouting steel pipes and limiting steel pipes are vertically inserted into the embedded steel pipes. The grouting steel pipes and the limiting steel pipes are inserted into the prefabricated unit plates. A plurality of limiting holes are formed in the track bottom foundation at intervals. According to the longitudinally-connected assembly type ballastless track structure provided by the embodiment of the invention, not only is the unit plate modules convenient to carry and convey, but also deformation coordination between the prefabricated unit plates is realized, and the limiting strength of the prefabricated unit plates is greatly improved.
本发明公开了一种纵连装配式无砟轨道结构及施工方法，属于无砟轨道领域领域。所述无砟轨道结构包括多个单元板模块、多个调平层和轨道底部基础。各单元板模块包括预制单元板和多个预埋钢管，各预埋钢管的两端均伸出相对应的预制单元板，任意相邻的两个单元板模块之间相对应的预埋钢管固结且连通，各预埋钢管上竖直插装有注浆钢管和限位钢管，注浆钢管和限位钢管插装在预制单元板上。轨道底部基础上具有多个间隔布置的限位孔。本发明实施例提供的一种纵连装配式无砟轨道结构，不仅便于单元板模块的搬运输送，并且实现预制单元板与预制单元板之间的变形协调，还极大的增大了对预制单元板的限位强度。
