Description

Vacuum pipeline and high-speed train with single pipe double lines and double pipes double lines arranged at intervals

Technical Field

The utility model relates to a vacuum pipeline traffic system technical field especially relates to a vacuum pipeline and high-speed train of single tube double-line and double-barrelled double-line interval arrangement.

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 pipe is not in a complete vacuum state, but air with a certain density exists, the vehicle still has aerodynamic action when running in the pipe, and considering the construction cost of the vacuum pipe, the sectional area of the pipe cannot be much larger than that of the train, so that the train has a 'blocking' effect when running at high speed in the pipe (the ratio of the sectional area of the train to the sectional area of the pipe is called a blocking ratio in the industry), an air compression wave is formed in front of the train running, an expansion wave is formed behind the train, the existence of the compression wave and the expansion wave causes the train to receive obvious aerodynamic resistance even when running in the vacuum pipe, and the compression wave generates high temperature rise, as shown in fig. 10 in particular.

In the case of a fault in a high-speed train running in the vacuum pipeline, the train needs to be stopped and passengers need to be evacuated, and the vacuum pipeline needs to be restored to a normal atmospheric pressure state before the train opens the doors. The vacuum pipeline is required to be restored to a vacuum state after the passengers are evacuated and the train fault is cleared.

At present, there is no engineering implementation and application of vacuum pipeline transportation worldwide, and from the technical solutions disclosed in the relevant information at home and abroad, there are two main solutions for the existing vacuum pipeline structure, the first solution is to design a track in a vacuum pipeline, and two vacuum pipelines are arranged side by side and are respectively used for bidirectional passing trains, as shown in fig. 6 and 7. The second solution is to design two tracks in the same vacuum tube, which are respectively used by trains running in two directions, as shown in fig. 8 and 9. The vacuum line of the prior art construction has several technical disadvantages.

First, in the first solution, due to the limited cross-sectional area of each pipe, there is a significant "choking" effect when the train is running, the running resistance is high and the aerodynamic effects cause a severe temperature rise in the pipes. If the cross-sectional area of the pipe is increased to reduce the blocking effect, the diameter of the vacuum pipe must be increased, and the construction cost of the line must be increased.

Secondly, the second scheme adopts a vacuum pipeline with a larger section, so that the 'blocking effect' of the running of the train is greatly weakened, the air resistance of the running of the train is favorably reduced, and the pneumatic heating phenomenon is also greatly weakened. However, in this scheme, if a train running in one direction breaks down and passengers need to be evacuated, the atmospheric pressure needs to be restored to the whole pipeline, and the normal passing of the train in the other direction is affected.

Third, no matter first scheme or second scheme, the vacuum pipe does not all design push-pull valve and escape opening, and when the train broke down in the course of the operation and needed the passenger evacuation, need to restore atmospheric pressure state with whole pipeline to the passenger can't be evacuated from in the pipeline, only can walk to the head and the tail end of pipeline along the pipeline, influences the efficiency of fleing, and need all restore the vacuum state to whole pipeline after the trouble-shooting again, consumes a large amount of energy, and consuming time very long.

Although the blockage of a train running on a double pipe and double line section is relatively large, the blockage effect is also advantageously reduced due to the shorter length of the double pipe and double line section. To further reduce the choking effect, as shown in fig. 5, communication valves 40 may be provided at regular intervals in the double pipe and double line sections to communicate the left and right vacuum pipes with each other, so that the compression wave generated in front of the train operation can enter the other pipe through the communication valves, thereby reducing the choking ratio.

In order to weaken the pneumatic disturbance action of a train passing through a junction of a single-pipe double-line pipe and a double-pipe double-line pipe, transition sections with certain lengths are arranged at two ends of a double-pipe double-line pipe section, and the section of a pipeline in the transition sections is gradually transited from a double-pipe double-line form to a single-pipe double-line form, as shown in fig. 1. In order to facilitate the transition between the single-pipe double-line pipe section and the double-pipe double-line pipe section, the vacuum pipeline structures of the single-pipe double-line pipe and the double-pipe double-line pipe are designed to be vertically split.

The pipeline structure of the single-pipe double-line pipe section is a vacuum pipeline formed by connecting an upper steel first structure 111 and a lower concrete second structure 112 through bolts 100, and a first rail 12 and a second rail 13 are designed in the vacuum pipeline and are used for a train running in two directions. The pipeline structure of the double-pipe double-line pipe section is formed by connecting an upper steel third structure 211, a steel fourth structure 221 and a lower concrete fifth structure 212 through bolts 100 to form two vacuum pipelines, and a track is designed in each vacuum pipeline.

No matter the vacuum pipeline is a single-pipe double-line or double-pipe double-line vacuum pipeline, the height and width of the vacuum pipeline structure can be designed freely by adopting an upper split type design, the height of the pipeline is increased as required, the vertical rigidity of the pipeline is improved, the transverse size is controlled, the use of steel and concrete materials is reduced, and the floor area of the line is reduced.

In addition, the split type vacuum pipeline is very convenient for construction of elevated road sections, firstly, the concrete structures at the lower parts are sequentially hoisted to the bridge piers 110 by using the bridge girder erection machine, the concrete structures at the lower parts form walking working lines of the bridge girder erection machine, and after the concrete structures at the lower parts are installed, the bridge girder erection machine is used for installing the upper parts in place one by one, so that the engineering construction is very convenient, and the construction cost of the lines is favorably reduced.

To sum up, the utility model provides a vacuum pipeline of single tube double-line and double-barrelled double-line interval arrangement, this vacuum pipeline compare with prior art, and its full play has the advantage of two kinds of current vacuum pipeline schemes, has abandoned its respective shortcoming and not enough, can enough effectively reduce the blocking effect of pipeline, reduces train running resistance and pneumatic temperature rise to when the train break down that moves on single direction needs to resume atmospheric pressure to the pipeline, do not influence the normal current of the ascending train in another direction. Furthermore, the utility model provides a vacuum pipeline can promote passenger safe sparse efficiency effectively, shortens the time that the pipeline resumes the vacuum state again greatly, reduces the energy consumption of evacuation.
