Fabricated ballastless track and construction method
The invention discloses a fabricated ballastless track and a construction method, and belongs to the field of ballastless tracks. The ballastless track comprises a steel rail, a plurality of fasteners, a plurality of prefabricated slabs, a concrete layer and a track bottom foundation which are sequentially arranged from top to bottom. The multiple prefabricated plates are evenly arranged at intervals in the length direction of the track bottom foundation, and a first steel pipe and a second steel pipe are inserted into the two ends of each prefabricated plate. A plurality of connecting steel bars are inserted in the track bottom foundation at intervals, and the top end of each connecting steel bar is located between every two adjacent prefabricated slabs. The concrete layer is provided with a plurality of limiting bosses, each limiting boss is inserted between every two adjacent prefabricated slabs, the connecting steel bars, the first steel pipes and the second steel pipes are inserted into the corresponding limiting bosses, and the concrete layer and the limiting bosses are integrally formed through reinforced concrete in a cast mode on site. According to the assembly type ballastless track provided by the embodiment of the invention, the overall structural strength of the ballastless track can be improved, and safety accidents are avoided.
本发明公开了一种装配式无砟轨道及施工方法，属于无砟轨道领域。所述无砟轨道包括从上至下依次布置的钢轨、多个扣件、多个预制板、混凝土层和轨道底部基础。多个预制板沿轨道底部基础的长度方向均匀间隔布置，各预制板的两端部插装有第一钢管和第二钢管。轨道底部基础上间隔插装有多个连接钢筋，各连接钢筋的顶端位于相邻的两个预制板之间。混凝土层上具有多个限位凸台，各限位凸台插装在相邻的两个预制板之间，且各连接钢筋、各第一钢管和各第二钢管插装在相对应的限位凸台中，混凝土层和多个限位凸台通过钢筋混凝土现场一体浇注成型。本发明实施例提供的一种装配式无砟轨道，可以提高无砟轨道的整体结构强度，避免引发安全事故。
