Assembly type ballastless track structure
The invention discloses an assembly type ballastless track structure, and mainly relates to the technical field of track traffic. The structure comprises a foundation bed layer, a base plate layer, a damping layer, a ballastless track plate layer and a steel rail which are sequentially arranged from bottom to top, and a plurality of limiting piles are arranged at the top of the foundation bed layer; the base plate layer comprises a plurality of base plates, the damping layer comprises a plurality of elastic vibration isolation pads, the ballastless track plate layer comprises a plurality of ballastless track plates, and the base plates, the elastic vibration isolation pads and the ballastless track plates are all provided with limiting holes matched with the limiting piles. The left end and the right end of the base plate are each provided with a limiting blocking table matched with a ballastless track plate. A plurality of through holes are vertically formed in the elastic vibration isolation pad, elastic columns are arranged in the through holes, and the height value of the elastic columns is larger than the thickness value of the elastic vibration isolation pad; according to the invention, vibration and noise during vehicle driving can be reduced, the demolition range can be reduced, and later operation and maintenance are facilitated.
本发明公开了一种装配式无砟轨道结构，主要涉及轨道交通技术领域；包括自下而上依次设置的基床层、底座板层、减震层、无砟轨道板层、钢轨，所述基床层的顶部设有若干个限位桩；所述底座板层包括若干个底座板，所述减震层包括若干个弹性隔振垫，所述无砟轨道板层包括若干个无砟轨道板，在所述底座板、弹性隔振垫、无砟轨道板上均设有与限位桩相适应的限位孔；所述底座板的左右两端均设有与无砟轨道板相适应的限位挡台；所述弹性隔振垫上竖直设有若干个贯穿孔，在所述贯穿孔内设有弹性柱，所述弹性柱的高度值大于弹性隔振垫的厚度值；本发明能够降低车辆行驶时的振动和噪音，能够减少拆迁范围，且方便后期的运维。
