Embodiment 2

[0083] Such as Figure 5 Shown, the second embodiment of the present invention a kind of supporting beam track structure of external guide magnet, with the magnetic levitation railway track of the present invention, can solve the track track of rail in laying stage, the adjustment problem of gauge, and solve in Correction of the track when subgrade settlement occurs during the operation phase can reduce the construction cost of rail laying and the later operation management cost. The fastener system fixes the rail on the track plate, which can adjust the track, and the backing plate in the fastener system can be used for dynamic and static adjustment of the track, which can accurately adjust the track. The track slab is a two-way prestressed track slab, and a CA mortar cushion or asphalt layer is set on the lower layer of the two-way prestressed track slab, which can make a transition between the track slab and the base plate. The two-way prestressed track slab is adopted, and...

Embodiment 3

[0086] Such as Image 6 Shown, the third embodiment of the present invention a kind of guide magnet built-in type maglev train rail transit system, comprises car body 90, uses the maglev railway track of the present invention, not only can solve the track gauge, the gauge of rail in laying stage The problem of adjustment, as well as solving the problem of rectifying the track when subgrade settlement occurs during the operation phase, can reduce the construction cost of rail laying and the later operation management cost. Moreover, it can also reduce the construction noise and the noise during the operation of the maglev transportation system. By controlling the noise generated by the maglev guidance system on the inner side of the track slab to the greatest extent, and then controlling the noise of the guidance system from spreading outward, the impact on the maglev railway during operation is reduced. The influence of the surrounding environment. The maglev railway rail tra...

Embodiment 4

[0089] Such as Figure 7 As shown, the fourth embodiment of the present invention is a kind of guide magnet built-in type maglev train rail transit system, including car body 90, with the maglev railway track of the present invention, the adjustment of the track length and gauge of the rail in the laying stage can be solved Problems, as well as solving the problem of correcting the track when subgrade settlement occurs during the operation phase, can reduce the construction cost of rail laying and the later operation management cost. The fastener system fixes the rail on the track plate, which can adjust the track, and the backing plate in the fastener system can be used for dynamic and static adjustment of the track, which can accurately adjust the track. The track slab is a two-way prestressed track slab, and a CA mortar cushion or asphalt layer is set on the lower layer of the two-way prestressed track slab, which can make a transition between the track slab and the base pl...

Abstract

The invention discloses a track deformation adjusting device and magnetic levitation railway tracks applying the same. The track deformation adjusting device comprises a track plate base, a track plate, a boss and an adjusting unit module. The track plate is arranged on the track plate base and provided with track bearing ditches which are used for mounting the steel tracks and fastener systems. The magnetic levitation railway tracks comprise a first side edge retaining wall and a second side edge retaining wall which are fixed to the railway track surface of a bearing beam, and the first sideedge retaining wall, the second side edge retaining wall and the railway track surface of the bearing beam form a U-shaped structure. According to the track deformation adjusting device and the magnetic levitation railway tracks applying the same, the track journey and the track gauge of the steel tracks at the laying stage are adjusted, the tracks are corrected during subgrade settlement at theoperating stage, and thus the laying construction cost and the later-period operating managing cost of the steel tracks are reduced; and noise can be reduced, escape tunnels and maintenance tunnels can be additionally formed, a magnetic levitation railway track traffic system is improved, and the safety guarantee capacity and the maintenance efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail deformation adjustment device and a maglev railway track using the device. Background technique [0002] At present, ballastless track technology is generally used in the roadbed of high-speed railways in my country. The ballastless track is fast and stable, but the subgrade of the ballastless track must be kept on a uniform level, and excessive settlement cannot occur during high-speed rail operation. The key to laying and operating ballastless track technology is to deal with the settlement of the subgrade. Therefore, in order to ensure the safety and comfort of the high-speed rail operation, the ballastless track has very strict requirements on the subgrade settlement after construction. The laying of the ballastless track must be analyzed and evaluated to meet the requirements. Check the settlement degree of the roadbed. [0003] In the curved section of...
