The invention provides a track beam structure covered with metal film and a split vacuum pipeline with the same. The track beam structure is connected with the upper structure of the pipeline to form a pipeline body, the pipeline body has an airtight vacuum pipeline cavity, and the track beam structure includes : Track beam body, the track beam body includes a first side wall, a second side wall and a track bottom structure, the second side wall is arranged in parallel with the first side wall, and the track bottom structure is arranged between the first side wall and the second side wall Between the first and second side walls, electrical coils are provided; the metal film is closely attached to the overall outer side of the track beam body, and the metal film is used to bear the effect of the atmospheric pressure difference between the inside and outside of the pipe body. The tensile stress generated on the outside of the track beam body and the air tightness of the track beam structure are improved. The technical solution of the present invention is applied to solve the technical problems of low structural strength, high line construction cost, large floor space and difficult construction of the vacuum pipeline in the prior art.
Description
technical field [0001] The invention relates to the technical field of magnetic levitation vacuum pipeline transportation systems, in particular to a track beam structure covered with a metal film and a split-type vacuum pipeline having the same. Background technique [0002] For high-speed public transportation, whether it is an airplane or a high-speed rail, the main resistance of its operation is air resistance. Air resistance limits the speed increase and also forms huge energy consumption. In order to increase the speed, people have already proposed vacuum The concept of pipeline + magnetic levitation, in order to reduce the air resistance of vehicle operation, the vehicle is enclosed in a vacuum pipeline to eliminate air resistance, and magnetic levitation technology is used to replace wheels and rails to eliminate mechanical friction resistance. [0003] The so-called vacuum pipeline is actually not an absolute vacuum state, but a certain density of air exists in the ...
