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

Embodiment 1

[0038] figure 1 It is a schematic cross-sectional view of a three-hole parallel maglev vacuum tunnel structure shown in a preferred embodiment. Its main structure is an operating tunnel 1 on both sides, a service tunnel 2 in the middle, and a connecting channel 3 between the three tunnels. The three tunnels are set up in parallel, and the relative distance between the tunnels can be adjusted appropriately according to the topographic and geological conditions of the specific project.

[0039] Specifically, the operating tunnel 1 is a prefabricated or cast-in-place reinforced concrete structure, and its shape can be circular or any other shape that can withstand external loads and vacuum additional loads. The interior is a vacuum environment, and it can also be set in combination with actual engineering. The specific vacuum degree and the size of the tunnel need to meet the requirements of the maglev train 6 for headroom, equipment layout and space requirements for passenger ev...

Embodiment 2

[0043] Optionally, in the scheme of the present invention, the arrangement of the equipment can follow the following principles, small equipment or cables are arranged in the running tunnel 1, and the larger equipment arranged along the running tunnel 1 is arranged in the service tunnel 2, which is convenient for heat dissipation and maintenance, Partially penetrating cables or pipes can be arranged in the cable cavity 11 of the filling 10 under the equipment. For other large-scale equipment with large installation intervals, it can be installed in the shaft or inclined shaft according to the actual project. If the ground has conditions, it can be installed on the ground.

Embodiment 3

[0045] Figure 2~Figure 3 It is a schematic cross-sectional view of the vacuum isolation wall 13 at the end of the communication passage 3 in a preferred embodiment, including the vacuum isolation door 7 and two reserved wall-through pipes 14 . Vacuum isolation door 7 can be circular, square and other shapes, and the size can accommodate personnel to pass through when evacuating or overhauling. Reserving the wall-piercing pipe 14 can directly be used as a ventilating pipe by connecting pipes at both ends, and also can wear small-diameter pipes or cables inside.

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 ...
