A platform transfer system for a subway station with separated left and right lines

Abstract

The present invention relates to a platform transfer system for a left-right separated subway station, comprising an upper station platform layer, a lower station platform layer and a connecting passage, wherein the lower station platform layer is provided with a right track of the lower station and a left track of the lower station on both sides; wherein: a down channel is provided in parallel in a dark excavation channel for constructing the right track of the lower station, and a first partition wall is provided between the down channel and the right track of the lower station; an up channel is provided in parallel in a dark excavation channel for constructing the left track of the lower station, and a second partition wall is provided between the up channel and the left track of the lower station, and the up channel and the down channel are respectively connected to the connecting passage. The present invention divides the transfer passage into two, namely, an up channel and a down channel, which are parallel to the left and right tracks of the lower station, thereby solving the problem that the existing transfer passage needs to be separately provided between the two tracks of the lower station, resulting in the risk of construction of three caverns with a small clearance.

Description

Technical Field

[0001] The invention relates to the field of urban rail transit, and in particular to a left-right line separated subway station platform transfer system which can effectively avoid the construction of multiple caverns with small clearance. Background Art

[0002] With the continuous development of urban rail transit and the increase of urban population, convenient transfer between subway lines has become more and more important in the design of subway stations. At the same time, in order to avoid the inconvenience caused to urban residents by traffic relief and pipeline relocation, more and more underground subway stations are adopted in urban rail transit design. Due to the limitations of underground stations, they cannot adopt heterogeneous designs like open-cut stations, so the transfer form of underground stations is relatively simple.

[0003] At present, in left-right line separated subway stations, when platform transfer passages are used between different lines, a separate passage needs to be constructed for transfer. This transfer passage is parallel to the two track sections of the lower line, which then causes the problem of small clear distance construction of three chambers. In addition, the construction is difficult, risky, has a long overall period and high project cost. Summary of the invention

[0004] Based on the problem of small clearance construction of three chambers when a transfer passage parallel to the lower track section needs to be separately set up at present, the present invention provides a left-right separated subway station platform transfer system which merges the upward and downward passages into the lower track section while reducing one transfer passage chamber, thereby realizing the upward and downward diversion of transfer passengers.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a left-right line separated subway station platform transfer system, including an upper station platform layer, a lower station platform layer and a communication channel for connecting the upper station platform layer and the lower station platform layer; wherein:

[0006] The right track of the lower station and the left track of the lower station are respectively arranged on both sides of the platform layer of the lower station; an upward channel is arranged in parallel in the concealed channel used for constructing the right track of the lower station, and a first partition wall is arranged between the upward channel and the right track of the lower station; a downward channel is arranged in parallel in the concealed channel used for constructing the left track of the lower station, and a second partition wall is arranged between the downward channel and the left track of the lower station; the upward channel and the downward channel are respectively connected to the connecting channel.

[0007] In the above scheme, the communication passage includes a transfer staircase and a track staircase connected to each other, the staircase hole of the transfer staircase is opened on the platform plate of the upper station platform layer, and the track staircase extends to the lower station platform layer.

[0008] Furthermore, the staircase hole of the transfer staircase is opened in the middle of the platform slab of the upper station platform layer.

[0009] Furthermore, the upper station right track and the upper station left track are respectively provided on both sides of the platform plate of the upper station platform layer, the transfer stairs extend downward to the bottom of the upper station track bottom plate, and the cross-track stairs pass closely through the upper station right track.

[0010] Furthermore, the transfer staircase includes an exit staircase and an entrance staircase arranged in parallel, the exit staircase is connected to the over-track staircase and the upward passage in sequence; the entrance staircase is connected to the over-track staircase and the downward passage in sequence, and railings are respectively provided between the exit staircase and the entrance staircase and between the over-track staircase.

[0011] Compared with the prior art, the present invention has the following advantages and effects:

[0012] 1. The present invention divides the platform transfer passage into two, namely, an upward passage and a downward passage; wherein, the downward passage and the right track of the lower station share a dark-cut passage, and are separated from each other by a first partition wall; the upward passage and the left track of the lower station share a dark-cut passage, and are separated from each other by a second partition wall; during construction, only the dark-cut caverns of the left track of the lower station and the dark-cut caverns of the right track of the lower station need to be excavated, which effectively reduces the setting of transfer passages arranged in parallel with the left and right track areas of the lower subway station in the existing multi-line transfer subway station, thereby avoiding the problem of construction of three-chamber small-clearance passages, reducing construction risks, shortening construction periods, and reducing project costs.

[0013] 2. The present invention eliminates the passenger transfer passage separately provided in the platform layer of the lower subway station, and divides the transfer passage into two by appropriately increasing the track section of the lower line section, thereby reducing construction risks and costs. Through the guidance of signboards, a one-way circulation of passenger flow can be achieved, ensuring the diversion of passenger flow into uplink and downlink, thereby improving the safety of passenger transfer and the comfort of riding, and having a high engineering promotion value.

[0014] 3. The present invention proposes a new transfer concept, which can reduce the size of dark excavation with large spans and multiple chambers while separating the up and down passenger flows, thus meeting both the requirements of construction safety and the needs of fire safety.
