An embedded frame track plate and its track structure

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...

AI Technical Summary

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, moisture, proportioning, mixing and other conditions, and the construction speed is slow. The organic solvents required for equipment cleaning after construction are harmful to the human body.

Moreover, polymer materials are expensive, and the overall cost of the orbital structure is relatively high

If it is necessary to replace the rails, due to the strong adhesive force of the polymer material, it is difficult to remove and the maintenance time is very long, which will seriously affect the normal operation
