Background technique
Pipeline train disengages elimination frictional resistance using suspension technology and ground, using inside close to the pipeline of vacuum
Air drag is greatly decreased in route, to realize train supersonic speed " near-earth flight ".
Suspended pattern can be divided into electrodynamics suspension, electromagnetic suspension, permanent magnet suspension at present.High-speed flight train running speed is fast,
It is required that the control of suspension system is simple as far as possible, float resistance than small, riding stability is high, and existing electromagnetic suspension technology magnetic resistance it is high,
Electrodynamics suspension control system is complicated, cannot meet the requirements.For permanent magnet suspension, conventional rails design is divided into two kinds, and one kind is in vehicle
It is laid with above body, being attracted each other by magnet makes vehicle suspend, and it is another to be laid with track in lower section, made by the mutual repulsion of magnet
Vehicle suspends.The first is high to the Structural strength calls of pipeline and track, and since vacuum pipe size and structural strength have accordingly
Limitation, therefore be laid with track above and be not suitable for high-speed vacuum pipeline train system.Therefore, second of laying orbital fashion is mesh
The mode that preceding high-speed flight train generallys use.
Currently, being laid with Track desigh using permanent magnet suspension and below car body under ultrahigh speed vacuum pipe environment
It is only carried out in thinking or laboratory, tracks of permanent magnetism is routed in support plate.If but used in engineering, due to train
The speed of service is high, and ultrahigh speed state lower railway precision and deformation have a very important role to traffic safety, therefore track is not
Only to guarantee very high precision, and also need to meet millimetre-sized deformation requirements, while ambient temperature in operating conditions
Deng also can when track deformation, this just to Track desigh, processing and construction links bring very big challenge.

Show, so that pipeline is while sealing, it is necessary to bearing track to the load of pipeline and vehicle by when the dynamic load that generates, make
It obtains to the more demanding of pipeline configuration intensity, while increasing the difficulty of seal for pipe joints, so that the difficulty and expense of pipe-line construction
It greatly increases.
Therefore further, to reduce seal for pipe joints difficulty and intensity requirement, track and pipeline are using carrying and sealing function
It can separate design.
The main supporting structure head penetrates in pipeline, and suspension railway system, suspension railway system position are installed in top
Inside pipeline, and there is the gap for being no less than 20mm between pipeline.
It designs in this way, so that pipeline is only subjected to internal and external pressure difference caused by self gravity and vacuum environment, and track
System, the weight of train and operation dynamic loading are undertaken by main supporting structure.In this case, main supporting structure penetrates inside pipeline
The shape that part can be convenient for using cylinder etc. and pipeline seals at wall-through.
Further, using carrying with sealing function separate design, the pipeline by bracket be supported on main supporting structure,
On ground or bridge pier.
The pipeline and main supporting structure is sealed by bellows.
The pipeline includes at least outside bearing pipe and inner seal pipeline.
The carrying of outside bearing pipe and environment resistant corrode, and are made of the higher material of intensity, such as mixed mud, specific to use
Material is determined according to design strength in conjunction with cost；Inner seal pipeline plays sealing function, there is the material system of good seal performance
At, such as carbon steel metal material, specifically determined using material according to design strength, seal request and cost.
If pipeline uses multi-layer piping, when sealing, bellows is intended to each layer pipeline closely coupled respectively, guarantees sealing.
