Description

Split type single-pipe double-line vacuum pipeline structure and magnetic suspension high-speed train using same

Technical Field

The invention relates to the technical field of vacuum pipeline traffic systems, in particular to a split type single-pipe double-line vacuum pipeline structure and a magnetic suspension high-speed train using the same.

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.

The so-called vacuum ducts are not completely vacuum but have a certain density of air, the vehicle still has aerodynamic effects when running in the ducts, and the cross-sectional area of the ducts cannot be much larger than the cross-sectional area of the train in view of the construction cost of the vacuum ducts, so that the train has a "choking" effect when running at high speed in the ducts (the ratio of the cross-sectional area of the train to the cross-sectional area of the ducts is referred to in the industry as the choking ratio). The existence of the blocking effect enables the train to be subjected to obvious pneumatic action even when the train runs in the vacuum pipeline, including pneumatic force and pneumatic temperature rise.

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. 5 to 8, wherein fig. 5 and 6 show the structure of a vertically arranged double-line vacuum pipeline, and fig. 7 and 8 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 two complete circular pipe structures, the basic structure of each large circular pipe is characterized in that a whole circular pipe structure is adopted to form a sealed and sealed space, a rail is built at the bottom in the circular pipe, specifically, as shown in figure 9, the vacuum pipeline of the circular pipe structure is not beneficial to improving the vertical rigidity of the cross section, the occupied area in the horizontal direction is large, the pipeline erection difficulty is large, the two circular pipe structures are horizontally or vertically arranged, only piers are shared, and the construction investment cost of the vacuum pipeline is high.

In addition, in the scheme disclosed by the prior document, only one track is designed in each vacuum pipeline, the cross-sectional area of the pipeline is small, the blocking effect is obvious when a train runs, the running resistance is large, and the temperature in the pipeline is severely increased due to the pneumatic action. If the blocking effect is reduced by increasing the cross-sectional area of the pipeline, the construction cost of the line is increased.

From the above, the two-line vacuum 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, because the cross-sectional area of each pipeline is limited, a remarkable 'blocking' effect exists when the train runs, the running resistance is large, and the temperature in the pipeline rises violently due to pneumatic action. If the blocking effect is reduced by increasing the sectional area of the pipeline, the pipe diameter must be increased, and the construction cost of the line must be increased.
