Abstract

The invention provides a fabricated ballastless track system and a construction method thereof. The fabricated ballastless track system comprises prefabricated track plates, a prefabricated base, prefabricated limiting structures, an isolation layer or a supporting seat, elastic buffering cushion layers and an on-site pouring layer, one or more limiting holes are formed in the centers of the prefabricated track plates, the prefabricated base is located on the lower parts of the prefabricated track plates, the prefabricated limiting structures extend into the limiting holes, the isolation layeror the supporting seat is arranged between the prefabricated track plates and the prefabricated base, the elastic buffering cushion layers are arranged between the limiting holes and the prefabricated limiting structures, and the on-site pouring layer is located on the lower part of the prefabricated base and is poured on site to be formed. According to the fabricated ballastless track system, the problems that in the prior art, a track system has poor ability to adapt to offline foundation deformation , and is low in on-site construction efficiency and poor in track structure durability aresolved.

Description

technical field [0001] The invention relates to the technical field of rail transit engineering, in particular to an assembled ballastless track system and a construction method for the assembled ballastless track system. Background technique [0002] The track structure of my country's urban rail transit mainly adopts short bearing block type or long pillow embedded cast-in-place track bed, and the national railway mainly adopts ballastless track types such as CRTS Ⅰ slab type, CRTS Ⅱ slab type and CRTS Ⅲ slab type. Among them, the short support block type, long pillow embedded type, elastic support block type, and double block ballastless track have a large amount of concrete poured on site, and there are disadvantages such as slow construction progress, cracking of the ballast bed, and high labor intensity of workers; CRTSⅠ type slab type, CRTSⅡ type Concrete base, cement-emulsified asphalt mortar layer / self-compacting concrete in slab-type and CRTSⅢ-type slab-type ballas...
