Embodiment Construction

[0021] figure 1 It is a cross-sectional view of the integral steel pipe structure. In the figure, 1 and 3 are cable troughs, 2 and 4 are supporting members, 5 is the side wall of the track, and 6 is an integral load-bearing steel pipe (taking a thickness of 25mm as an example).

[0022] The specific implementation of the scheme: according to different division of labor, the cables are classified and buried in the cable trough (1) and the cable trough (3), which greatly saves time for later maintenance. At the same time, the components (2) and (4) can provide support for cable troughs and other facilities, and the I-shaped component (4) can also protect the track sidewall (5) to a certain extent. The integral load-bearing steel pipe (6) can not only bear traffic load and external air pressure, but also play a good sealing function. The program has good overall performance.

[0023] figure 2 It is a cross-sectional view of the steel pipe-main beam combined structure. In the figur...

Abstract

The invention discloses a vacuum high-speed traffic pipeline which comprises a first steel plate and a second steel plate, wherein the cross section of the first steel plate is arc-shaped, and the second steel plate is a flat plate; the left side edge of the first steel plate is connected to the left side edge of the second steel plate, and the right side edge of the first steel plate is connectedto the right side edge of the second steel plate; and a left cable trough and a right cable trough are formed in the inner wall of the pipeline along a radial direction and are respectively positioned at the left and right connecting parts of the first steel plate and the second steel plate. The vacuum high-speed traffic pipeline disclosed by the invention has the beneficial effects that three structure schemes can be formed by expansion, and the gas tightness is good. Different structure schemes can be selected according to different objective conditions, so that materials are saved, and strength characteristics are also fully exerted; and the space utilization ratio of the interior of the pipeline is improved to the maximum extent, and a pedestrian passageway for maintenance personnel to perform overhaul is reserved, so that later maintenance is relatively convenient. The vacuum high-speed traffic pipeline disclosed by the invention also has the characteristics of low cost, high space utilization ratio, resource saving and the like.

Description

Technical field [0001] The invention relates to the technical field of vacuum high-speed transportation, in particular to a vacuum high-speed transportation pipeline. Background technique [0002] In order to meet people's travel needs, convenient, low-energy, high-stability, and ultra-high-speed new vehicles have become the direction of exploration by researchers in the transportation field of various countries, and vacuum high-speed transportation is one of them. Existing transportation modes are all exposed to the atmospheric environment, so that there is atmospheric resistance when vehicles are running. Atmospheric resistance requires energy consumption and at the same time limits the increase in vehicle speed. An effective solution is to make the vehicle run in a vacuum environment with no or little atmospheric resistance, thereby increasing the vehicle speed and reducing energy consumption. This is the vacuum high-speed transportation method. Vacuum high-speed transportat...
