Description

Split type double-pipe double-line vacuum pipeline structure with perspective effect

Technical Field

The invention relates to the technical field of vacuum pipeline traffic systems, in particular to a split type double-pipe double-line vacuum pipeline structure with a perspective effect.

Background

For mass transportation vehicles running at high speed, no matter an airplane or a high-speed rail, the main running resistance of the vehicles is air resistance, the air resistance limits the speed increase, and huge energy consumption is formed.

At present, the vacuum pipeline transportation does not enter the engineering implementation and application stage worldwide, and from the technical solutions disclosed in the related information at home and abroad, the conventional common double-line pipeline structure is specifically shown in fig. 6 to 9, wherein fig. 6 and 7 show the structure of a vertically arranged double-line vacuum pipeline, and fig. 8 and 9 show the structure of a horizontally arranged double-line vacuum pipeline. The cross section shapes of the two types of double-line vacuum pipelines are both two complete circular pipe structures, the basic structural characteristic of each large circular pipe is that a sealed and closed space is formed by adopting the whole circular pipe structure, and a track is built at the bottom of the circular pipe, and the two types of double-line vacuum pipelines are particularly shown in figure 10. The vacuum pipeline of this kind of pipe structure is unfavorable for improving sectional vertical rigidity to horizontal direction area is big, and the pipeline erects the degree of difficulty big, and two pipe structures present level or vertical arranging, have only shared the pier, and the general construction investment cost who sees this kind of vacuum pipeline is high.

In addition, the pipelines introduced in the disclosed information have no perspective effect, passengers cannot browse scenery outside the window in the vehicle, no visual experience is available, and the possibility of space claustrophobia to part of passengers is provided for long-time riding in a closed invisible space.

From the above, the two-wire pipe in the prior art has the following disadvantages in use.

First, the large circular pipes forming the two pipelines in the prior art can only share the bridge pier, and the bridge part cannot share the bridge pier, so that the construction cost of only part of the bridge pier can be saved compared with two single lines.

Second, the strength properties of concrete materials and steel are not fully exploited for each pipe. The action load on the pipeline when a vehicle runs in the vacuum pipeline is mainly vertical, so that the section of the pipeline is required to have high bending rigidity in the vertical direction, the horizontal direction does not need too high rigidity, and the bending capacities of the whole circular steel pipe in the vertical direction and the horizontal direction are the same and unreasonable. In addition, the section geometry of the concrete part cannot be designed too high due to the limitation of the round pipe, more materials are distributed in the horizontal direction, the vertical rigidity of the pipeline is insufficient, the horizontal rigidity is excessive, and the strength performance of the materials is not fully utilized.

Thirdly, construction at elevated bridge sections is difficult. The vacuum pipeline is made into a section with the length of dozens of meters when in use, the vacuum pipeline is installed on a viaduct by using bridging equipment, the upper side of the pipeline of the whole circular pipe structure is arc-shaped, only one layer of steel plate is arranged, the dead weight of a bridge girder erection machine cannot be borne, particularly the double-line pipeline form which is vertically arranged is more difficult to construct, and the construction cost is high as a result of the great difficulty in engineering construction.

Fourth, the line footprint of a two-wire pipeline construction is large. Particularly for the double-line pipeline form arranged horizontally, because the transverse and vertical dimensions of each large circular pipe are the same, in order to increase the bending vertical rigidity, the diameter of the circular pipe must be increased, and the increase of the transverse dimension increases the floor area of the vacuum pipeline circuit, thereby increasing the line construction cost.

Fifthly, each pipeline of the existing double-line pipeline structure has no design in the aspect of visual effect, even if a porthole is designed on a vehicle, a passenger can see only a dark space in the pipeline through the porthole, the passenger can not take a very good visual experience, and the possibility of space claustrophobia of the passenger who takes a part for a long time can be avoided.
