Bridge track structure based on ballastless track and construction method
The invention discloses a bridge track structure based on a ballastless track and a construction method, and belongs to the technical field of ballastless tracks. The bridge track structure comprises a bridge and a ballastless track. A plurality of limiting bosses arranged at intervals are arranged on the top face of the bridge, and the bridge and the limiting bosses are integrally formed by pouring reinforced concrete. The ballastless track comprises two steel rails, a plurality of fasteners, a plurality of concrete filled steel tube sleepers and a plurality of roadbed slabs which are sequentially arranged from top to bottom, the roadbed slabs are sequentially arranged in the length direction of the steel rails, and each roadbed slab is of a plate-shaped structure formed by cast-in-place concrete among the concrete filled steel tube sleepers. Limiting grooves are formed in the bottom faces of the roadbed slabs through cast-in-place concrete, and the limiting bosses are inserted into the corresponding limiting grooves. According to the bridge track structure based on the ballastless track provided by the embodiment of the invention, stable assembly of the roadbed slab and the bridge can be conveniently realized, so that the construction progress is accelerated.
本发明公开了一种基于无砟轨道的桥轨结构及施工方法，属于无砟轨道技术领域。所述桥轨结构包括桥梁和无砟轨道。桥梁的顶面具有多个间隔布置的限位凸台，桥梁和限位凸台为钢筋混凝土一体浇筑成型。无砟轨道包括从上至下依次布置的两个钢轨、多个扣件、多个钢管混凝土轨枕和多个道床板，多个道床板沿钢轨的长度方向依次布置，各道床板为在多个钢管混凝土轨枕之间现浇混凝土成型的板状结构，且各道床板的底面通过现浇混凝土形成限位凹槽，各限位凸台插装在相对应的限位凹槽中。本发明实施例提供的一种基于无砟轨道的桥轨结构，不仅可以便捷实现道床板和桥梁的稳定装配，从而提高施工进度。
