Description

Technical Field

[0001] The invention relates to the technical field of subway facilities, and in particular to an evacuation structure in a subway. Background Art

[0002] In recent years, urban subways have gradually developed into the preferred method to solve the increasingly tense urban traffic problems due to their high passenger capacity, punctuality, safety and convenience. With the continuous densification of subway lines in major cities, the number of train failures and fires has gradually increased, which has put forward higher requirements for interval evacuation in emergency and fire conditions. How to quickly evacuate people in the interval and effectively avoid major safety accidents is an urgent problem to be solved.

[0003] At present, the interval evacuation platform is generally disconnected 10m outside the station end wall, and the interval down-track stairs are set at the end of the interval evacuation platform to the track bed. People evacuate along the track bed to the inside of the station, and then go up to the equipment area walkway through the stairs at the end of the equipment area in the station, and then evacuate to the station hall level. Subway stations generally have civil defense emergency cover functions. Interval civil defense partition doors are set at one end of the station. In extreme cases, when a train catches fire and the train loses power at the civil defense door, the width of the civil defense door of the general urban subway interval partition door is 3.8m (the width of the subway car type A is 3.0m, and the width of the type B car is 2.88m). The gap between the car and the civil defense door of the type A car is only 0.4m, and the gap between the car and the civil defense door of the type B car is only 0.46m, which does not meet the minimum 0.55m evacuation width requirement in the "Metro Design Code" GB50157-2013. In order to solve the problem of insufficient width at the civil air defense door, some cities have widened the civil air defense door to 4.2m. Although this meets the evacuation width of the train stopped at the civil air defense door, passengers still need to go down the stairs from the section evacuation platform to the roadbed, cross the civil air defense threshold and track drainage ditch, which is inconvenient for passengers to evacuate. Summary of the invention

[0004] The purpose of the present invention is to provide an evacuation structure in a subway, which improves the convenience of passenger evacuation and enhances the safety of passengers during evacuation.

[0030] like Figures 1 to 3 As shown, according to an embodiment of the present invention, there is provided an evacuation structure in a subway, wherein a tunnel and a subway station are provided in the subway, and the evacuation structure in the subway includes an interval evacuation structure and a wiring area evacuation structure. Above the subway tunnel is a ground plane 7, the subway station has a platform slab 4, the position between two adjacent subway stations is a subway interval (referred to as the interval), and the interval evacuation structure includes: an interval evacuation platform 3, the interval evacuation platform 3 extends along the length direction of the subway tunnel and is connected to the side wall of the subway tunnel, the interval evacuation platform 3 extends to connect with the platform slab 4, and the width of the interval evacuation platform 3 is ≥600mm, which fully meets the requirements for the evacuation width. The material of the interval evacuation platform 3 in the subway interval is prefabricated RPC material, and the material of the interval evacuation platform 3 inside the station is a cast-in-place concrete structure.

[0031] Preferably, when a subway section partition door 2 is provided at the end position of the subway station, the evacuation structure also includes: a civil air defense evacuation door 1, which is provided on the door frame wall at the end position of the subway station. When the civil air defense evacuation door 1 is opened, the section evacuation platform 3 and the platform board 4 are connected. When the subway section partition door 2 is closed, the subway station section can be closed. The subway station and the section are used as civil air defense emergency shelters. Generally, a subway section partition door 2 is provided above the main line at the end of the station. When the subway section partition door 2 is closed, the subway section can be closed to achieve the effect of closed protection. In order to ensure that the section evacuation platform 3 at the subway section partition door 2 is connected to the platform board 4, a civil air defense evacuation door 1 should be added above the platform board 4. After the civil air defense evacuation door 1 is added, even if a subway section partition door 2 is provided at the end of the station, the section evacuation platform 3 can still be connected to the platform board 4.

[0032] Preferably, the interval evacuation structure also includes a ramp 6, and a section of the interval evacuation platform 3 connected to the platform 4 is set as a ramp 6. The ramp 6 connects the interval evacuation platform 3 and the platform 4 to the interval evacuation platform. The interval evacuation platform 3 is sloped within the interval range. By setting the ramp 6, the interval evacuation platform 3 is connected to the platform 4, thereby avoiding the need to set steps to facilitate passenger evacuation.

[0033] Preferably, the interval evacuation structure also includes an interval down-rail staircase 5, which is connected to the platform 4. Passengers can evacuate through the interval down-rail staircase 5. In addition, since there are subway tunnels on both sides of the platform 4, corresponding interval evacuation platforms 3 and civil air defense evacuation doors 1 will be set corresponding to each subway tunnel. In some cases, passengers can evacuate through other civil air defense evacuation doors 1.

[0034] Preferably, the civil air defense evacuation door 1 is a single-leaf two-way force-bearing protective closed door; the height of the single-leaf two-way force-bearing protective closed door is 2m, and the width of the single-leaf two-way force-bearing protective closed door is 0.9m.

[0035] Preferably, the civil air defense evacuation door 1 is a double-leaf one-way force-bearing protective closed door; the height of the double-leaf one-way force-bearing protective closed door is 2m, and the width of the double-leaf one-way force-bearing protective closed door is 0.8m.

[0036] Preferably, the distance between the upper end of the interval evacuation platform 3 and the rail surface of the subway track is 800 mm to 900 mm.

[0037] Preferably, the length of the ramp 6 is 5m to 7m. To facilitate evacuation, the slope of the ramp 6 must be no greater than 1:12. The height difference between the interval evacuation platform 3 and the platform slab 4 is not very large. Generally, the length of the ramp 6 can meet the slope requirements within the range of 5m7m, such as 5m, 5.5m, 6m, 6.5m, and 7m, so that the slope of the ramp 6 is convenient for passenger evacuation and avoids the setting of steps. The interval evacuation platform 3 is generally about 850mm higher than the rail surface, and the platform slab 4 is about 1050mm higher than the rail surface. The height difference between the two is about 200mm. The length of the ramp 6 is preferably 6m. The ramp 6 connected to the interval evacuation platform in the interval can make the interval evacuation platform 3 and the platform slab 4 smoothly connected within the range of 6m, which is convenient for passenger evacuation.

[0038] like Figure 4-Figure 7 As shown, preferably, the station distribution area has a station floor, the distribution area track passes through the station distribution area, and the distribution area evacuation structure includes a distribution area evacuation platform 8, a platform underrail staircase 9, an evacuation path 10 and an equipment area end staircase 12; the distribution area evacuation platform 8 is arranged along the line centerline in the length direction, the distribution area evacuation platform 8 extends along the length direction of the subway tunnel and is connected to the side wall of the subway tunnel, the distribution area evacuation platform 8 is arranged along one side of its width direction to the subway train vehicle limit value, and the upper end of the platform underrail staircase 9 is connected to the end of the distribution area evacuation platform 8; the evacuation path 10 is arranged on the station floor, and the two ends of the evacuation path 10 are respectively connected to the lower end of the platform underrail staircase 9 and the equipment area end staircase 12.

[0039] In the above embodiment, a wiring area evacuation platform 8 is added to the subway wiring area. The length direction of the wiring area evacuation platform 8 is set along the center line of the line. The width of the wiring area evacuation platform 8 should meet the evacuation requirements. One side of the wiring area evacuation platform 8 along the width direction is set to the vehicle limit value. At the same time, the distance between the upper end surface of the wiring area evacuation platform 8 and the track surface of the wiring area track is close to the distance between the bottom surface of the vehicle's carriage and the track surface, that is, the height of the upper end surface of the wiring area evacuation platform 8 should be close to the bottom surface of the vehicle's carriage, so that passengers can step onto the wiring area evacuation platform 8 from the vehicle. For example, for a subway type B vehicle, the distance between one side of the wiring area evacuation platform 8 along its width direction and the center line of the line is 1.6m. The starting point of the wiring area evacuation platform 8 is connected to the wiring area evacuation platform 8 in the station section (the position between two adjacent subway stations is the subway section), and the end of the wiring area evacuation platform 8 is provided with a platform under-track staircase 9, so that passengers can enter the station floor from the wiring area evacuation platform 8. An evacuation path 10 is arranged on the station floor, and the two ends of the evacuation path 10 are respectively connected to the lower end of the platform lower rail staircase 9 and the equipment area end staircase 12, so as to facilitate the evacuation of passengers. The evacuation structure of the wiring area of ​​the subway station solves the problem that the wiring area of ​​the conventional station has no wiring area evacuation platform 8, which not only effectively avoids the risk of passengers jumping from the carriage when the subway vehicle loses power in the wiring area, but also facilitates the evacuation of passengers and improves the evacuation efficiency.

The wiring area evacuation platform 8 is a cast-in-place concrete structure, and the height of the wiring area evacuation platform 8 is 850mm higher than the rail surface, which means that the distance between the center plane of the wiring area evacuation platform 8 and the rail surface is 850mm. The other side of the wiring area evacuation platform along the width direction is the side connected to the side wall of the subway tunnel, and the handrail 14 is connected to the side wall of the subway tunnel.

[0041] The width of the wiring area evacuation platform 8 is not less than 600 mm, and this width range is convenient for passengers to walk on the wiring area evacuation platform 8. A railing handrail 14 is set above the other side of the wiring area evacuation platform 8 along the width direction, and the railing handrail 14 is 900 mm higher than the upper end surface of the wiring area evacuation platform 8, so that it is convenient for passengers to use the railing handrail 14 when walking, ensuring the safety of passengers during evacuation.

[0042] In order to solve the problem that when passengers are evacuating along the evacuation path 10, there are connecting rails such as point rails, guide rails, wing rails, and guard rails at the turnout, which hinders the evacuation of passengers and poses a safety hazard, in one embodiment of the present invention, a wiring area ramp 11 is also included. The wiring area ramp 11 is set at the position where the evacuation path 10 passes through the wiring area track, and the wiring area ramp 11 can be used to travel from one side of the wiring area track to the other side. The wiring area ramp 11 is set at the position where the evacuation path 10 passes through the wiring area track, and is set on both sides of the wiring area track rails, so that the evacuation path 10 is smoother, which greatly improves the evacuation efficiency of the station wiring area, effectively avoids major safety accidents, and realizes barrier-free evacuation.

[0043] Preferably, in order to facilitate construction and make the evacuation path 10 smoother, in one embodiment of the present invention, the wiring area ramp 11 is prefabricated with concrete, the bottom end of the wiring area ramp 11 is in contact with the station floor, the height of the wiring area ramp 11 is the same as the height of the wiring area track, the wiring area ramp 11 includes a first side slope 111, a second side slope 112 and a platform 113, the first side slope 111 and the second side slope 112 are respectively located on the outside of the two outermost rails in the wiring area track, the platform 113 is located inside the wiring area track, and the ends of the first side slope 111 and the second side slope 112 extend to the drainage ditch respectively. Among them, the first side slope 111 and the second side slope 112 are respectively located on the outside of the two outer rails, and the first side slope 111 and the second side slope 112 both have a certain slope, which is convenient for passengers to walk. Preferably, in one embodiment of the present invention, the longitudinal sections of the first side slope 111 and the second side slope 112 are right-angled trapezoids. In addition, the platform body 113 is located inside the wiring area track, and the steel rails inside the wiring area track all pass through the platform body 113. The height of the platform body 113 is the same as the height of the steel rails in the wiring area track, so that the smoothness inside the wiring area track is better and barrier-free evacuation can be achieved. Preferably, in one embodiment of the present invention, the wiring area track includes two steel rails, and no steel rails inside the wiring area track pass through the platform body 113, so the cross-section and longitudinal section of the platform body 113 are both rectangular.

[0044] In order to solve the problem that passengers need to cross the drainage ditch when evacuating along the evacuation path 10, which poses a safety hazard, in one embodiment of the present invention, a cover plate 13 is also included, and the cover plate 13 is arranged above the drainage ditch of the distribution area track. The cover plate is arranged above the drainage ditch through which the evacuation path 10 passes, so that the evacuation path 10 is smoother, further improving the evacuation efficiency of the station distribution area, effectively avoiding major safety accidents, and realizing barrier-free evacuation. Preferably, in order to make the structure more stable, in one embodiment of the present invention, the width of the cover plate 13 is 200 mm and the thickness of the cover plate 13 is 50 mm.

[0045] In order to more clearly define the evacuation path 10 and facilitate the evacuation of passengers, in one embodiment of the present invention, a reflective strip 101 is provided along the evacuation path 10. By providing the reflective strip 101 along the evacuation path 10, the evacuation path 10 can be clearly defined, the evacuation of passengers can be facilitated, and the evacuation efficiency can be improved.

[0046] In order to enhance the lighting on the evacuation path 10 and facilitate the evacuation of passengers, in one embodiment of the present invention, a plurality of lighting devices are arranged along the evacuation path 10. By installing lighting devices along the evacuation path 10, the lighting within the evacuation path 10 can be increased to facilitate the evacuation of passengers. Preferably, in order to provide better lighting within the evacuation path 10, in one embodiment of the present invention, the lighting device is installed 2.5m away from the station floor so that the illumination within the evacuation path 10 is not less than 5lx.

[0047] In order to facilitate passengers to evacuate along the evacuation path 10, in one embodiment of the present invention, a plurality of evacuation indications are provided along the evacuation path 10.

At the same time, it solves the problem of safety hazards caused by the need to cross the wiring area track rails and drainage ditches when evacuating along the evacuation path 10, making the evacuation path 10 smoother, greatly improving the evacuation efficiency of the wiring area, effectively avoiding major safety accidents, and realizing barrier-free evacuation.

[0049] The interval evacuation structure solves the problem of discontinuity between the interval evacuation platform 3 and the platform slab 4 by connecting the interval evacuation platform 3 with the platform slab 4. Even if a subway interval partition door 2 is provided at the end of the station, the interval evacuation platform 3 can still be connected with the platform slab 4.
