Problems solved by technology

[0005] The purpose of the present invention is to: provide a simple structure, complete functions, fast and convenient construction, high precision, can adapt to the pavement requirements of different foundation treatment forms, can meet the current urban rail transit "green, environmental protection, low energy consumption, impact on residents' lives The prefabricated embedded track slab required by the "small" solution solves the problem that the existing track construction adopts on-site construction, which requires the cooperation of a variety of large-scale construction machinery, occupies a large area of ​​the road, is difficult to organize traffic, is noisy, and has a great impact on the lives of nearby residents. The technical problems of low quality and high energy consumption can effectively solve the problems in the above-mentioned prior art

Embodiment 1

[0047] Example 1 : This track slab is used for independent right of way, mainly used to bear the load of trams and provide urban greening at the same time.

[0048] Such as figure 2 As shown, the prefabricated track slab does not need the necessary sleepers and fasteners on the traditional track slab, and adopts a non-prestressed reinforced concrete structure. The prefabricated track slab is placed on the foundation that meets the requirements of the elastic modulus, assembled and laid along the line, and prefabricated track slabs of different specifications and sizes are laid on different road sections, such as straight lines and curved sections; the track slab is reserved with slots for greening , can achieve the effect of urban greening, consistent with the surrounding environment.

[0049] In this example:

[0050] 1. This track slab is a rail embedded track slab; it is suitable for the section where the rail adopts 59R2 grooved rail and is filled with polymer composi...

Embodiment 2

[0057] Example 2 : This track slab is mainly used for sharing the right of way, and bears the load of trams and cars at the same time.

[0058] Such as image 3 As shown, in order to enhance the structural bearing capacity, the prestressed reinforced concrete structure is adopted. Grouting holes, water collection tanks, pre-embedded adjustment rods, hoisting parts, steel plates, drainage pipes, etc. are reserved for the track slab; asphalt, concrete or other materials consistent with the road surface can be poured on the surface of the prefabricated track slab to be flush with the road surface.

[0059] In this example:

[0060] 1. This track slab is a rail embedded track slab. It is suitable for the section where the rail uses 59R2 grooved rail and is filled with polymer composite materials to lock the rail.

[0061] 2. The concrete strength grade of the track slab is C50. Raw materials such as cement, sand, stone and water used in concrete shall comply with the relevan...

Abstract

The invention discloses a prefabricated embedded type rail plate which comprises prefabricated rail plate body. The prefabricated rail plate comprises a reinforced concrete plate, a rail bearing groove, an embedded steel plate and a reserved port. The rail bearing groove is a structure that a steel rail is embedded into the prefabricated rail plate. The reinforced concrete plate comprises a prestress structure and a non-prestress structure. The embedded steel plate is welded with reinforced steel bars in the reinforced concrete plate. A greening groove opening is reserved on the upper surface of the rail plate, or a pavement layer is positioned on the upper surface of the rail plate. The prefabricated embedded type rail plate is completely different from a rail plate manufactured in site and is prefabricated in factorization standard and installed in a module mode in site. The rail plate is simple in structure, small in maintenance, green and environmental-friendly, reduces effects of engineering construction on existing traffic to the maximum degree, simplifies construction technologies, enhances operability and improves construction speed.

Description

technical field [0001] The invention relates to a track slab, in particular to an embedded track slab which is prefabricated in a factory and modularly installed on site, and belongs to the technical field of urban rail transit. Background technique [0002] As an urban public transportation system, modern trams are being vigorously developed around the world. With the revival of international trams, we are familiar with trams again, and high-tech elements have been integrated into contemporary trams. In my country, modern trams were first applied in Dalian City; after that, Shenyang Hunnan New Area was building 6 tram lines in combination with the development of new cities; in the research and planning of the rail transit network in Suzhou, combined with the characteristics of the city, it was also 6 tram lines have been arranged; Jiaxing plans to arrange 3 tram lines within the urban area when combining the planning and research of the intercity rail transit network; the Sh...
