Description

Technical Field

[0001] The present invention belongs to the technical field of underground engineering, and specifically relates to a structure for connecting an evacuation platform and a platform in a civil defense section of an underground station, which is suitable for underground stations of urban rail transit, urban rail, magnetic levitation and other projects. Background Art

[0002] Urban rail transit, a green mode of travel, brings people high efficiency, comfort and economy, but it also has certain safety hazards. The safe evacuation of subways is directly related to the life safety of passengers and is an issue that needs to be studied in depth.

[0003] In the rail transit lines that have been put into use, when passengers use the interval evacuation platform to evacuate to the station, the evacuation path between the interval and the platform is usually disconnected. Passengers need to go down from the interval longitudinal evacuation platform to the track area roadbed surface through the steel ladder, and then evacuate to the platform through the stairs set at the end of the platform. Especially at the end of the station where the interval civil air defense door is set, it is necessary to walk a long distance on the roadbed surface. Although the specification requires that the track area roadbed surface is an evacuation cable channel, most domestic rail transit projects do not pay enough attention to the evacuation of passengers on the roadbed surface. For example, a central ditch is set on the roadbed surface, and no cover is set, and silt accumulates in the ditch, making it difficult for passengers to evacuate; the cable pipelines crossing the roadbed are arranged in a messy manner, and the contact rails, beacons and other live equipment close to the roadbed surface bring certain safety hazards to the evacuation of passengers. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a structure for connecting the evacuation platform of the civil defense section of an underground station with the platform, which can improve the safety, continuity and clarity of the evacuation path at the interface between the section and the station platform level, and reduce the safety risks of passengers.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is a structure connecting an interval evacuation platform of an underground station civil defense section with a platform, comprising a platform, a civil defense partition door structure and an interval evacuation platform arranged in a shield interval tunnel on one side of the platform; the civil defense partition door structure is arranged at one end of the platform close to the shield interval tunnel; the civil defense partition door structure comprises civil defense partition door stacks arranged on both sides of the track, and the platform board in the platform and the interval evacuation platform are respectively located on both sides of the civil defense partition door stack; the platform board and the interval evacuation platform are arranged on the same side of the track; the civil defense partition door stack close to the platform board is widened in a direction perpendicular to the track, and a civil defense door is provided on the widened part of the civil defense partition door stack; the platform board extends through the civil defense door to the side of the civil defense partition door stack away from the platform board, and is connected to the interval evacuation platform through a connecting plate.

[0006] Furthermore, the connecting plate is arranged to be inclined downward from the platform plate to the interval evacuation platform.

[0007] Furthermore, the width of the civil air defense partition door after widening is not less than 2400 mm.

[0008] Furthermore, the civil defense partition door structure also includes a civil defense partition door frame and a civil defense partition door, and both sides of the civil defense partition door frame are respectively connected to the civil defense partition door stacks on both sides of the track, and one side of the civil defense partition door is hinged to a side of the civil defense partition door frame away from the platform board.

[0009] Furthermore, the distance between the door frame of the civil air defense partition door and the edge of the tunnel door at one end of the shield section tunnel close to the platform is not less than 1500mm.

[0010] Furthermore, the civil air defense door is a threshold-free steel structure.

[0011] Furthermore, the drainage pipe in the shield section tunnel extends along the connecting plate, and is arranged along the wall at the end of the platform after being bent at the edge of the portal at one end of the shield section tunnel close to the platform, and then passes upward through the middle plate of the platform and is connected to the station hall layer.

[0012] Furthermore, a pipeline crossing area is provided above the platform plate located above the part of the civil air defense door close to the shield section tunnel side and above the section evacuation platform.

[0013] Furthermore, the pipeline crossing area is located no less than 2200 mm above the platform plate and the interval evacuation platform.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The present invention widens the door stack of the air defense partition door near the platform in a direction perpendicular to the track and adds an air defense door on the widened part, so that the interval evacuation platform is smoothly connected to the platform. Passengers can evacuate directly to the platform without going down to the track bed surface, which greatly improves the safety, continuity and clarity of the evacuation path at the interface between the interval and the station platform layer, and reduces the evacuation risk;

[0016] (2) The present invention adjusts the position of the civil air defense partition door structure and ensures that the distance between the door frame of the civil air defense partition door and the edge of the tunnel door at one end of the shield section tunnel close to the platform is not less than 1500 mm, so as to meet the requirements of evacuation width and pipeline turning installation.

[0024] like Figure 1-Figure 2 As shown, this embodiment provides a structure in which an interval evacuation platform of an underground station civil air defense section is connected to a platform, comprising a platform 1, a civil air defense partition door structure 2, and an interval evacuation platform 31 arranged in a shield interval tunnel 3 on one side of the platform 1; the civil air defense partition door structure 2 is arranged at one end of the platform 1 close to the shield interval tunnel 3; the civil air defense partition door structure 2 includes civil air defense partition door stacks 21 arranged on both sides of the track, and the platform plate 11 in the platform 1 and the interval evacuation platform 31 are respectively located On both sides of the civil air defense door stack 21; the platform board 11 and the interval evacuation platform 31 are arranged on the same side of the track; the civil air defense door stack 21 close to the platform board 11 is widened in a direction perpendicular to the track, and a civil air defense door 4 is provided on the widened part of the civil air defense door stack 21; the platform board 11 extends through the civil air defense door 4 to the side of the civil air defense door stack 21 away from the platform board 11, and is connected to the interval evacuation platform 31 through the connecting plate 5. In this embodiment, the civil defense door pier 21 near the platform plate 11 is widened in a direction perpendicular to the track, and a civil defense door 4 is added to the widened part, and the section evacuation platform 31 is connected with the platform plate 11 to the part of the anti-partition door pier 21 facing the shield section tunnel 3 through the connecting plate 5. Passengers can be evacuated directly to the platform 1 through the connecting plate 5 and the civil defense door 4 without going down to the track bed surface, which greatly improves the safety, continuity and clarity of the evacuation path at the interface between the section and the station platform layer, and reduces the evacuation risk.

[0025] Furthermore, the connecting plate 5 is arranged to be tilted downward from the platform plate 11 to the interval evacuation platform 31. Since there is a certain height difference between the interval evacuation platform 31 and the platform plate 11, the interval evacuation platform 31 is connected to the platform plate 11 by an inclined connecting plate 5, so that the passengers on the interval evacuation platform 31 can be evacuated to the platform plate on the side of the civil air defense partition door pier 21 close to the interval evacuation platform 31 through the connecting plate 5.

[0026] Furthermore, the width of the civil air defense partition door pier 21 after widening is not less than 2400mm. In this embodiment, the civil air defense partition door pier 21 close to the platform slab 11 is widened to add a civil air defense door 4 on the civil air defense partition door pier 21, so that the platform 1 is connected with the shield section tunnel 3, and the passengers in the shield section tunnel 3 can evacuate to the platform 1 without going down to the track section roadbed surface.

[0027] Furthermore, the civil defense partition door structure 2 also includes a civil defense partition door frame 22 and a civil defense partition door 23. Both sides of the civil defense partition door frame 22 are respectively connected to the civil defense partition door stacks 21 on both sides of the track, and one side of the civil defense partition door 23 is hinged to the side of the civil defense partition door frame 22 away from the platform plate 11.

[0028] Furthermore, the distance between the door frame 22 of the civil air defense partition door and the edge of the tunnel door of the shield section tunnel 3 at one end close to the platform 1 is not less than 1500 mm, so as to meet the requirements of evacuation width and pipeline turning installation.

[0029] Furthermore, the civil defense door 4 in this embodiment is a civil defense door with a threshold-free steel structure.

[0030] Furthermore, the drainage pipe 6 in the shield section tunnel 3 extends along the connecting plate 5, and is arranged along the wall at the end of the platform 1 after being bent at the edge of the portal at one end of the shield section tunnel 3 close to the platform 1, and then passes upward through the middle plate of the platform 1 and is connected to the station hall layer.

[0031] Furthermore, a pipeline crossing area 7 is provided above the platform 11 located on the side of the civil air defense door 4 close to the shield section tunnel 3 and above the section evacuation platform 31. Furthermore, the pipeline crossing area 7 is located not less than 2200mm above the platform 11 and the section evacuation platform 31. In this implementation, the professional pipelines of each system (power supply, power lighting, FAS / BAS pipelines / bridges) need to be adjusted to a range above 2200mm above the section evacuation platform surface and the platform surface to meet the clear height of the evacuation passage; the power supply cable 71 and bridge, FAS / BAS cable 72 and bridge, power lighting cable 73 and bridge can be arranged as follows: Figure 1 After passing through the pipeline crossing area 7 from above the air defense door 4, the professional pipelines of each system pass down to the pipeline crossing area set below the part of the platform 11 located on the side of the air defense door 4 away from the shield section tunnel 3.

[0032] The present invention takes passenger safety as the main consideration and optimizes the problem of the existing section evacuation platform being disconnected from the platform. Passengers can directly enter the platform from the section evacuation platform, reducing the many safety hazards that exist when passengers go up and down stairs, walk on a long section of the roadbed, and find stairs to the platform in an emergency evacuation state. In addition, the present invention does not affect the project investment. It only optimizes the interface evacuation mode between the section and the station platform through refined design, improves the safety of passenger evacuation, and reduces operational risks. It fully reflects the people-oriented design principle and has excellent application prospects in similar engineering fields.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
