Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] Figure 5 with Image 6 The existing ballastless track configuration is shown. refer to Figure 5 , the existing ballastless track structure includes three main structural layers, the track slab 10, the CA mortar adjustment layer 40, and the base 30, which are sequentially arranged from top to bottom. The track slab 10 adopts a prestressed reinforced concrete structure, and the base 30 adopts reinforced concrete structure. The advantage of the CA mortar adjustment layer 40 is that it can be easily maintained and replaced. However, since the CA mortar adjustment layer 40 cannot connect the track plate 10 and the base structure layer 30 as a whole, the structure of the ballastless track has poor integrity and cannot meet the needs of improving Requirements for track seismic performance. refer to Figure 5 with Image 6 , in order to constrai...
