Novel slab ballastless track structure
The invention relates to a novel prefabricated slab ballastless track structure for high-speed railways and urban rail transit. The novel prefabricated slab ballastless track structure comprises rails, fasteners, prefabricated track slabs, under-slab filling and adjusting layers, a base and limiting bosses, wherein the track slabs are of a middle hollowed-out frame structure (through holes), the bosses (5) are arranged on the base (4) corresponding to the middle through holes of the prefabricated track slabs, and the limiting bosses (5) are single or multiple. The novel prefabricated slab ballastless track structure has the advantages that the pulling stress to the adjusting layers can be reduced, the track slabs bear larger pulling stress and the high-strength large-rigidity functions of the track slabs can be fully performed; since the track slabs are provided with through holes, the manufacturing cost is reduced, the longitudinal temperature stress to the track slabs is also relieved and the warping of the corners of the unit slab track structure is greatly reduced; since the limiting bosses are located in the middles of the track slabs, the replacement of parts such as the track slabs and the repair and treatment such as elevation and deviation correction in case of non-uniform settlement of tracks are facilitated.
