Three-hole parallel magnetic levitation vacuum tunnel structure

Abstract

The invention discloses a three-hole parallel magnetic levitation vacuum tunnel structure. The structure comprises running tunnels on the two sides and a service tunnel on the middle. The running tunnels and the service tunnel are connected through a connection channel, the interiors of the running tunnels are vacuum environments, the bottoms of the running tunnels are in under-rail filling, a magnetic levitation rail beam is placed on the filling face, a magnetic levitation train runs on the magnetic levitation rail beam, the interior of the service tunnel is the normal pressure environment,the bottom of the service tunnel is in filling under equipment, equipment needed by magnetic levitation running is placed on the filling face, other spaces serve as evacuation channels, one end of theconnection channel communicates with the running tunnels, the other end of the connection channel communicates with the service tunnel, and a vacuum isolation wall and a vacuum isolation door are arranged on the connecting position of the communication channel and the running tunnels. The low-vacuum environment can be ensured, the ground space use can be reduced, adaptation to the terrain is high, the tunnel structure with good passenger evacuation, personal inspection and equipment arranging capacity is achieved, and meanwhile, practicability, safety and economy are all considered.

Description

technical field [0001] The invention belongs to the technical field of vacuum pipeline maglev transportation, in particular to a three-hole parallel maglev vacuum tunnel structure. Background technique [0002] With the gradual improvement of the domestic high-speed rail backbone network, high-speed rail passenger transport has gradually matured and has become an important form of transportation that supports the development of my country's transportation industry. With the needs of national economic development, people's demand for long-distance, fast and convenient transportation has further increased. [0003] Comparing the high-speed high-speed rail and airplane transportation, the high-speed rail runs at 250-350km / h, and the airplane runs at 600-800km / h. There is still a considerable speed range between the two, and there is a lack of transportation to fill the gap. To meet people's demand for fast transportation. [0004] As the most potential transportation form at ...

AI Technical Summary

Problems solved by technology

[0005] At present, the research on low-vacuum pipelines is mainly based on short-distance experimental lines on the ground, and there are many restrictive factors in engineering applications: 1. Long-distance ground lines occupy surface space, especially in large cities. Construction is difficult; 2. Due to the climate The influence of factors is large, and the temperature change causes the longitudinal expansion and deformation of the pipeline, which is difficult to solve in engineering; 3. The noise and vibration generated by the ground line will still affect the surrounding environment

Therefore, the study of underground pipelines in the form of tunnels has obvious advantages, but the current research is still less involved
