Problems solved by technology

However, the self-compacting concrete of the filling layer is mixed centrally and transported to the site by tanker for pouring, which results in a large waste and high cost. At the same time, when the organic elastic material of the limit groove under the slab deteriorates and the track structure is destructively damaged, the maintainability is poor.

Embodiment 1

[0045] Such as Figure 1 ~ Figure 4 As shown, a new type of assembled ballastless track structure includes a concrete base 1, on which a plurality of track plates 2 are arranged, and a steel rail 3 is installed on the track plate 2 through a fastener system 4; The upper surface of the concrete base 1 is prefabricated with convex blocks 5 distributed in parallel at equal distances, and several of the convex blocks 5 are arranged along the length direction of the concrete base 1; 5 are provided with the track plate 2 and form a unit, and the outer walls of the two longitudinal ends of the track plate 2 of each unit are respectively provided with draw-in slots 6, and the draw-in slots 6 and the convex stop 5 are set in one-to-one correspondence; the adjacent track plates 2 are independently set and the gap distance is maintained, and an independent detachable adjustment layer is set between the track plate 2 of each unit and the concrete base 1 7. The longitudinal ends of the ad...

Embodiment 2

[0064] The difference between this embodiment and the first embodiment is that an adjustment layer of another structure is provided.

[0065] Such as Figure 5 with Figure 6 As shown, the adjustment layer 7 in each unit is a split structure, including the sub-adjustment layer 701 arranged in half; the distance between the sub-adjustment layers 701 arranged in half is maintained.

[0066] The adjustment layers arranged in this way can be poured separately, and there is no contact between the half adjustment layers 701, forming a horizontal spacing, which can be used as a horizontal drainage ditch 11; avoiding setting up drainage on the concrete base 1 The construction process of the ditch can not only maintain the integrity of the concrete base 1 but also not affect drainage while not affecting the height adjustment and support of the adjustment layer to the track slab 2 .

Embodiment 3

[0068] The difference between the present embodiment and the first embodiment is that another setting method of the convex stopper is provided.

[0069] Such as Figure 7 As shown, the convex block 5 and the concrete base 1 are integrally casted; then grooves are formed around the convex block 5 to merge with the longitudinal drainage ditch to form a complete drainage ditch 11 .

[0070] Such arrangement has not only avoided pouring and forming the convex block 5 separately, but also does not need to set up drainage ditches under the convex block 5, and the construction is more convenient.

Abstract

The invention discloses a novel assembly type ballastless track structure and a mounting method thereof. The novel assembly type ballastless track structure comprises a concrete base, track plates andsteel rails, convex blocking tables which are distributed in parallel at equal intervals are prefabricated on the upper surface of the concrete base. The track plates are arranged between the adjacent convex blocking tables in a clamped mode, and clamping grooves are formed in the outer walls of the two longitudinal ends of each track plate respectively. Every two adjacent track plates are independently arranged, a gap distance is kept between every two adjacent track plates, an independent detachable adjusting layer is arranged between each track plate and the concrete base, receding groovesare formed in the positions, corresponding to the clamping grooves, of the two longitudinal ends of each adjusting layer respectively, and the receding grooves clamp the convex blocking tables. Elastic assemblies are further arranged between the inner sides of the clamping grooves and the convex blocking tables and between the inner sides of the receding grooves and the convex blocking tables. According to the ballastless track structure, the superrelation on curve can be achieved, the construction is easy and convenient, the height of the track plates is easy to adjust, the adjusting layerscan be replaced and maintained, and the later maintenance cost is low.

Description

technical field [0001] The invention relates to the technical field of ballastless track, in particular to a novel assembled ballastless track structure and an installation method thereof. Background technique [0002] At present, my country's ballastless track is mainly divided into double block type and slab type ballastless track. There are two types of double-block ballastless track, CRTSⅠ and CRTSⅡ. The CRTSⅠ double-block type is derived from the Radar 2000 track in Germany. Its appearance is characterized by a protruding rail support on the surface and a section of the rail support on the inner side of the track. The CRTSⅡ double-block type is derived from the Schuplin track in Germany. The appearance feature is that the rail support platform is square instead of arc-shaped. This type of ballastless track is only laid in Zhengxi Passenger Train. CRTS I double blocks are more common. The base is laid in advance, the sleepers are prefabricated, and then several sleeper...
