Problems solved by technology

[0003] On the one hand, high-speed maglev trains run on rails, and it is difficult to set up rescue channels. If the train breaks down in the elevated section, how to rescue becomes one of the primary problems. There is also a technical solution for setting up steel support rescue channels between the track beams in the double-track section. , but the steel bracket is easy to rust and difficult to maintain
[0004] On the other hand, in order to ensure the smoothness of the track and the installation accuracy of the lattice components, the track beam needs to be manufactured with high precision of the whole hole beam, and the precision control needs to be at the millimeter level. As a load-bearing structure, the track beam is large in size and heavy in weight, causing processing It is very difficult and requires high-precision installation at the same time, it is difficult to hoist, and the construction is difficult, resulting in a substantial increase in the cost of the project

Abstract

The invention discloses a high speed electromagnetic suspension track structure. The high speed electromagnetic suspension track structure comprises a base, a filling layer and a track board; the baseis located at the bottom of the track structure, serves as a transmission component for support upper part load and force, and transmits the upper part load to a bridge, roadbed or tunnel; the trackboard is located at the top of the track structure, serves as a support and guiding structure of a high speed maglev, and is used for achieving track holding operation of the maglev; and the filling layer is arranged between the base and the track board, plays a role of adjusting space coordinates of the track board, and is used for achieving high precision mounting of the track board. According to the high speed electromagnetic suspension track structure, function parts of the track structure are separated from a spandrel girder to be arranged individually, and can be directly arranged on thebridge, on the roadbed or in the tunnel, the two ends of the track structure can serve as rescue channels to solve the challenge of rescue, the track board is only needed to be machined and manufactured in a high precision mode, construction below the track board can be controlled to be constructed according to conventional accuracy, difficulty of construction can be effectively lowered, and theconstruction cost is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of high-speed maglev rail transit, and in particular relates to a high-speed maglev rail structure, which is suitable for high-speed maglev rail transit with a maximum speed of over 600 km per hour. Background technique [0002] Compared with the wheel-rail system, the biggest difference between the high-speed maglev system and the wheel-rail system is that the high-speed maglev vehicle runs on the rail. The existing technology uses a track beam with integrated beam and rail as the supporting structure and guiding structure of the maglev train. The track beam also has a load-bearing beam. And the function of the track, the domestic Shanghai high-speed maglev operation line uses this kind of track beam. [0003] On the one hand, high-speed maglev trains run on rails, and it is difficult to set up rescue channels. If the train breaks down in the elevated section, how to rescue becomes one of the primary proble...
