Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit, and in particular relates to a rail transit station and an operation method thereof. Background Art

[0002] In recent years, with the continuous development of urbanization in my country, traffic congestion has become a common problem. As an important part of the comprehensive transportation system, urban rail transit is in the process of vigorous development. However, with the continuous expansion of urban scale, the planned and constructed rail transit lines are getting longer and longer, and some lines are even longer than 80km, resulting in excessively long operation time of urban rail transit and inconvenience in transportation organization.

[0003] For lines that are too long, some cities adopt a model of through-line operation in the short term and segmented operation in the long term; at this time, it is necessary to dismantle the through-line operation and split a line into two sections for independent operation. For lines that need to be dismantled in the long term, it is necessary to study the dismantling plan in advance and make civil engineering reservations during the project implementation. In view of this situation, it is necessary to study a station layout type that allows rail transit to achieve both through-line operation and segmented independent operation, thereby reducing project abandonment and avoiding the impact of line dismantling on operations. Summary of the invention

[0004] The present invention relates to a rail transit station and an operation method thereof, which can at least solve some defects of the prior art.

[0005] The present invention relates to a rail transit station, comprising two sets of station line structures;

[0006] Each set of station line structures includes an effective platform, an in-station main line and an arrival and departure line, wherein the in-station main line and the arrival and departure line share the effective platform and are connected by a first single crossover line, and the first single crossover line is located at the front side of the corresponding effective platform;

[0007] The two effective platforms are arranged opposite to each other, the two main lines in the station are located between the two effective platforms and are connected by two sets of second single crossovers, and the two sets of second single crossovers are respectively arranged at the front side and the rear side of any effective platform.

[0008] As one of the implementation methods, the line spacing between two main lines within the station is ≥4.5m.

[0009] As one of the implementation modes, each set of station line structure also includes a return line, which is connected to the end of the corresponding main line in the station, and the return line is connected to the corresponding arrival and departure line through a switch and a connecting line behind the switch.

[0012] As one of the implementation modes, the end of the arrival and departure line connected to the branch rear connecting line extends to the rear side of the corresponding effective platform.

[0013] The present invention also relates to an operation method of the rail transit station as described above, wherein the rail transit station adopts a segmented operation mode and / or a through operation mode.

[0014] In the segmented operation mode, two sets of station-line structures are used independently, each effective platform serves as the starting and ending station of a section of rail transit line, one of the station main line and the arrival and departure line of each set of station-line structures serves as the entrance line of the corresponding rail transit line, and the other serves as the exit line, and the first single transfer line is used to realize the train turning back before the station;

[0015] In the through-operation mode, the rail transit station serves as a general intermediate station, and the two effective platforms are used by up and down trains respectively. The trains pass through the first single crossover in front of the station and the second single crossover after the station corresponding to the effective platform.

[0016] As one of the implementation modes, each station line structure further includes a return line, the return line is connected to the end of the corresponding station main line, and the return line is connected to the corresponding arrival and departure line through a turnout and a connecting line behind the turnout;

[0017] In the segmented operation mode, the train can also return after the station through the branch connection line and the return line.

[0018] As one of the implementation modes, in the through-operation mode, the return line serves as a temporary fault parking line.

[0019] The present invention has at least the following beneficial effects:

[0020] The rail transit station provided by the present invention, through the unique design of the track layout design of the two sets of station line structures and the single crossover track connection type between the two sets of station line structures, can simultaneously realize the operation mode of rail transit line through operation and segmented independent operation, avoiding the abandonment of the project and the adverse impact on the operation caused by the dismantling of the line.

The turnout connecting line 5 is preferably a curved track, which is convenient for the layout of the track; affected by the width of the effective platform 1, the distance between the station main line 2 and the arrival and departure line 3 of each station line structure is relatively large, generally ≥15m, and the turnout connecting line 5 is preferably a circular arc track with a radius of ≥200m; in addition, it is preferred to ensure that the turnout connecting line 5 does not invade the platform and meets the platform superelevation gradient requirements, then the turnout connecting line 5 and the corresponding effective platform 1 preferably retain a straight line length, that is, the end of the arrival and departure line 3 connected by the turnout connecting line 5 extends to the rear side of the corresponding effective platform 1.

[0027] The operation method of the above-mentioned rail transit station is described below. The rail transit station adopts a segmented operation mode and / or a through operation mode. Specifically:

[0028] In the segmented operation mode, two sets of station-line structures are used independently, each effective platform 1 serves as the starting and ending station of a section of rail transit line, one of the station main line 2 and the arrival and departure line 3 in each set of station-line structures serves as the entrance line of the corresponding rail transit line, and the other serves as the exit line, and the first single transfer line 7 is used to realize the train turning back before the station;

In addition, preferably, in the station structure, in the through operation mode, the reversing line 4 serves as a temporary fault stop line.

[0031] The operation method of the above rail transit station is further explained below through a specific operation example:

[0032] (1) Figure 2 , for ease of description, is defined as follows:

[0033] One set of station-line structures includes a first effective platform 11, a first arrival-departure line 31, a first station main line 21, and a first return line 41. The first return line 41 is connected to the end of the first station main line 21. The first arrival-departure line 31 is connected to the first return line 41 through a first branch-back connecting line 51 and a first switch 61. The first arrival-departure line 31 is connected to the first station main line 21 through a first single crossover line 71.

[0034] Another set of station-line structures includes a second effective platform 12, a second station main line 22, a second arrival-departure line 32, and a second return line 42. The second return line 42 is connected to the end of the second station main line 22. The second arrival-departure line 32 is connected to the second return line 42 through a second fork-back connecting line 52 and a second turnout 62. The second station main line 22 is connected to the second arrival-departure line 32 through a first single crossover line 72.

[0035] The first station main line 21 and the second station main line 22 are both located between two effective platforms 1, and the first station main line 21 and the second station main line 22 are connected by a second single crossover line 1 81 and a second single crossover line 2 82, the second single crossover line 1 81 is located at the rear side of the first effective platform 11, and the second single crossover line 2 82 is located at the front side of the first effective platform 11;

[0036] (2) In the segmented operation mode, the first valid platform 11 is used as the starting and ending station of the first segment, and the second valid platform 12 is used as the starting and ending station of the second segment. The train has two return modes: return before the station and return after the station.

[0037] The running path of the train on the first section of the line turning back before the first effective platform 11 is: the first arrival and departure line 31 (entry) → the first single transfer line 71 → the first effective platform 11 (passengers getting on and off) → the first station main line 21 (exit);

[0038] The running path of the train on the first section of the line turning back after the first effective platform 11 is: the first arrival and departure line 31 (entering the station) → the first effective platform 11 (passengers getting off the train) → the first branch connecting line 51 → the first switch 61 → the first turning line 41 → the first effective platform 11 (passengers getting on the train) → the first station main line 21 (exiting the station);

[0039] The running path of the train on the second section of the line turning back before the second effective platform 12 is: the second arrival and departure line 32 (entering the station) → the first single transfer line 2 72 → the second effective platform 12 (passengers getting on and off the train) → the second station main line 22 (exiting the station);

[0040] The running path of the train on the second section of the line that turns back after the second effective platform 12 is: second arrival and departure line 32 (entering the station) → second effective platform 12 (passengers getting off the train) → second switch back connecting line 52 → second switch 62 → second return line 42 → second effective platform 12 (passengers getting on the train) → second station main line 22 (exiting the station).

[0041] (3) Under the through-train operation mode, the rail transit station serves as a general intermediate station;

[0042] The running route of the upward train passing through the rail transit station is: the first arrival and departure line 31 (entry) → the first single transfer line 71 → the first effective platform 11 (passengers getting on and off) → the second single transfer line 81 → the second station main line 22 (exit);

[0043] The running path of the down train passing through the rail transit station is: the second arrival and departure line 32 (entry) → the first single transfer line 2 72 → the second effective platform 12 (passengers get on and off) → the second single transfer line 2 82 → the first station main line 21 (exit), and the up and down trains do not interfere with each other. In this case, the first return line 41 and the second return line 42 can be used as temporary fault stop lines respectively.

[0044] It can be seen that the rail transit station provided in the embodiment of the present invention, through the unique design of the track layout design of the two sets of station line structures and the single crossover connection type between the two sets of station line structures, can simultaneously realize the operation mode of through operation of the rail transit line and independent operation of the sections, thereby avoiding the abandonment of the project and the adverse effects on the operation caused by the dismantling of the line.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
