Problems solved by technology

The disadvantage of this structure is that the temperature stress of the rail is limited by the bonding of the prefabricated restraining block to the rail and the bonding force of the polymer material to the periphery of the rail bearing groove.
In particular, polyurethane polymer materials are sensitive to temperature, which will lead to poor stability of rail gauge and direction, and cause rail wear
On-site mixing and filling of organic polymer materials has high requirements on ambient temperature, ...

Embodiment 1

[0067] figure 1 Front view of the embedded frame track slab.

[0068] figure 2 Left view for embedded frame track slab.

[0069] image 3 A top view of the embedded frame track slab.

[0070] Such as figure 1 , figure 2 and image 3 As shown, the embedded frame track plate 10 includes: two symmetrically arranged rail bearing grooves 11, rail bearing groove sleeves 12, gauge adjustment bolts 13, rail compression stoppers 14, connecting beams 15, longitudinal anchors Tube 16, longitudinal connecting screw 17 and floor groove 18.

[0071] The rail bearing groove 11 is used to place the steel rail 20, and several rail bearing groove sleeves 12 are arranged symmetrically on both sides of the rail bearing groove 11. Each rail bearing groove sleeve 12 has a gauge adjusting bolt 13 inside, and the rail gauge adjusting bolt 13 A rail compression limiter 14 is arranged between the bolt 13 and the rail 20 . The embedded track slab supports mechanically adjusting and restrictin...

Embodiment 2

[0120] Figure 18 It is a schematic diagram of the embedded track structure on the tram bridge in Embodiment 2.

[0121] Such as Figure 18 Shown is the embedded track structure on the tram bridge. The construction method and procedure are the same as Example 1. The difference is that the construction of the base needs to plant bars on the bridge deck, and the construction of the protective fence needs to be bonded with epoxy resin mortar, etc. Adhesive construction on the bridge deck.

[0122] Variation 2

[0123] Figure 19 It is a schematic diagram of the embedded track structure of the tram embankment section in Modification 2.

[0124] Such as Figure 19 Shown is the embedded track structure of the tram embankment section, and the construction method and procedure are the same as the first example.

Embodiment 3

[0126] Figure 20 It is a schematic diagram of the subway tunnel embedded track structure in Embodiment 3.

[0127] Such as Figure 20 Shown is the embedded track structure of the subway tunnel, the construction method and procedure are the same as the first example, and the base construction method is the same as the second example. The difference lies in that the outer dimension of the track slab is slightly changed, the center of the track bed should be a prefabricated flat plate 103, and the filling of sand and gravel in the track bed is cancelled.

Abstract

The invention discloses an embedded track plate and a track structure comprising the same. The structure comprises the embedded frame track plate, steel tracks, an under-track rubber plate, a filling material, a limiting leveling layer, a base and a track bed base layer, wherein the base is fixed on the track bed base layer; the limiting leveling layer is arranged on the base; the embedded frame track plate is arranged on the limiting leveling layer; the steel tracks are arranged in track bearing grooves of the embedded frame track plate; track gage adjusting screws and steel track compression limiters adjust positions of the steel tracks in the track bearing grooves and fix the steel tracks in the track bearing grooves; the under-track rubber plate is further arranged between the steel tracks and the track bearing grooves; the track bearing grooves are filled with the filling material. The advantage that the track structure can be derived into an on-bridge track structure, a subgrade track structure, a tunnel-inside track structure, a level crossing track structure and a curved track structure according to the difference of using sites is realized.

Description

technical field [0001] The patent of the invention relates to an embedded track slab and its track structure, in particular to the urban tram track structure and subway shock-absorbing and noise-reducing track structure and the technical field of maintenance. Background technique [0002] In the late 1980s, France, Germany, Spain, Belgium, the Netherlands, and Shanghai, China re-opened trams in urban road traffic. The new trams are beautiful in appearance, low in noise, large in capacity, fast in speed, and without repetition Lines, do not use fuel oil, etc., share the advantages of urban ground roads with cars and are called the third generation of new trams. The third-generation trams that have been built in my country include steel-wheeled railcars in Dalian, Shenyang, and Suzhou, rubber-tyred monorails in Zhangjiang High-Tech Zone in Shanghai, and rubber-tyred monorails in Tianjin Binhai New Area. The total mileage is very short, and other cities are under planning or un...
