Description
[0001] The present invention relates to the technical field of rail transit ventilation and smoke discharge, and in particular, relates to a fire ventilation and smoke discharge system and method for a station hall of a separated island subway underground station.
[0002] Due to limited space inside a city, most subway stations of an urban area are underground stations. Operation safety of an underground station is a very prominent problem. Casualties caused by diffusion of smoke and toxic substances generated by combustion inside a subway station and a subway tunnel are of the most harm. Subway fire is much more harmful than fire of a ground building. Once subway fire occurs, losses caused are generally very large, and it is mainly reflected as: firstly, thick smoke and large smoking volume are caused by incomplete combustion due to insufficient oxygen of the underground station. Meanwhile, there are less entrances and exits for subway, such that a large amount of smoke can flow out only from one or two openings, resulting in a slow speed of flow of air with ground. “Air suction” effects of underground openings enable a part of smoke flowing outside to be suctioned back by openings, resulting in suffocation easily. Secondly, the number of exits communicating subway and ground are limited, passengers inside subway are of large number and crowded, such that evacuation is slow. Once a fire occurs, it is possible to cause mass injuries and deaths. Therefore, an effective ventilation and smoke discharge system has a very significant meaning for reduction of casualties.
[0003] A conventional subway station platform is mainly divided into an island platform and a side platform. However, at present, some subways are built along an urban overhead. Since pillars of the overhead obstruct large-scale excavation of a road, a station integrated with a station hall and a platform cannot be built. The direct method to solve the problem is to increase burial depth of the subway station. However, the method significantly increases excavation difficulties and cost. Another solution is to arrange two rail tunnels, platforms and station halls respectively at two sides of pillars of the overhead and to excavate channels between pillars for shuttling with each rail tunnel, station and station hall. A station of such type is generally referred to as an separated island station. At present, there has not been a generally approved effective ventilation and smoke discharge method for the station of such type.

This can effectively prevent smoke from spreading toward a smoke-proof partition that is not on fire. Using an elaborate fire mode can significantly improve smoke discharge efficiency, realize targeted smoke discharge and effectively reduce ineffective smoke discharge.

[0057] As shown in Fig. 1, embodiments of the present invention provide a fire ventilation and smoke discharge system for a station hall of a separated island subway underground station, wherein the station hall of a separated island subway underground station comprises two station halls that are separated from each other, each of the station halls comprising two adjacent smoke-proof partitions, which communicate with opposing smoke-proof partitions of another station hall through channels, wherein each of the smoke-proof partitions is provided with an air supply sub-system and a smoke discharge sub-system in a one-tone-one correspondence manner, an air supply pipe of the air supply sub-system is arranged in a smoke-proof partition corresponding to the air supply sub-system and a channel in communication with the smoke-proof partition; and a smoke discharge pipe of the smoke discharge sub-system is arranged in a smoke-proof partition corresponding to the smoke discharge sub-system and a channel in communication with the smoke-proof partition.
[0058] Specifically, the two station halls are respectively a first station hall Al and a second station hall A2. The first station hall Al comprises two adjacent smoke-proof partitions, which are respectively a first smoke-proof partition C1 and a second smoke-proof partition C2; and the second station hall A2 comprises two adjacent smoke-proof partitions, which are respectively a third smoke-proof partition C3 and a fourth smoke-proof partition C4. The first smoke-proof partition C1 is in communication with the third smoke-proof partition C3 through a first channel B1, and the second smoke-proof partition C2 is in communication with the fourth smoke-proof partition C4 through a second channel B2.
[0059] The first smoke-proof partition C1 is provided with a corresponding first air supply sub-system and a corresponding first smoke discharge sub-system, wherein a first air supply pipe K1 of the first air supply sub-system is arranged in the first smoke-proof partition C1 and the first channel B1 and it can be disposed in a T shape.

The first smoke discharge pipe L1 is evenly provided with a plurality of smoke discharge outlets.
[0060] Similarly, the second smoke-proof partition C2 is provided with a corresponding second air supply sub-system and a corresponding second smoke discharge sub-system, wherein a second air supply pipe K2 of the second air supply sub-system is arranged in the second smoke-proof partition C2 and the second channel B2 and it can be disposed in a T shape. The second air supply pipe K2 is evenly provided a plurality of air supply outlets. The second air supply pipe K2 can be disposed relative to the first air supply pipe K1. A second smoke discharge pipe L2 of the second smoke discharge sub-system is also arranged in the second smoke-proof partition C2 and the second channel B2 and it can also be disposed in a T shape. The second smoke discharge pipe L2 is evenly provided with a plurality of smoke discharge outlets. The second smoke discharge pipe 12 can be disposed relative to the first smoke discharge pipe LI.
[0061] The third smoke-proof partition C3 is provided with a corresponding third air supply sub-system and a corresponding third smoke discharge sub-system, wherein a third air supply pipe K3 of the third air supply sub-system 1s arranged in the third smoke-proof partition C3 and the first channel B1 and it can be disposed in a T shape. The third air supply pipe K3 is evenly provided a plurality of air supply outlets. The third air supply pipe K3 can be disposed relative to the first air supply pipe K1. A third smoke discharge pipe L3 of the third smoke discharge sub-system is also arranged in the third smoke-proof partition C3 and the first channel B1 and it can also be disposed in a T shape. The third smoke discharge pipe L3 is evenly provided with a plurality of smoke discharge outlets. The third smoke discharge pipe L3 can be disposed relative to the first smoke discharge pipe L1.
[0062] The fourth smoke-proof partition C4 is provided with a corresponding fourth air supply sub-system and a corresponding fourth smoke discharge sub-system, wherein a fourth air supply pipe K4 of the fourth air supply sub-system is arranged in the fourth smoke-proof partition C4 and the second channel B2 and it can be disposed in a T shape. The fourth air supply pipe K4 is evenly provided a plurality of air supply outlets. The fourth air supply pipe K4 can be disposed relative to the second air supply pipe K2 and the third air supply pipe K3 respectively. A fourth smoke discharge pipe L4 of the fourth smoke discharge sub-system is also arranged in the fourth smoke-proof partition C4 and the second channel B2 and it can also be disposed in a T shape. The fourth smoke discharge pipe LA is evenly provided with a plurality of smoke discharge outlets. The fourth smoke discharge pipe LA can be disposed relative to the second smoke discharge pipe L2 and the third smoke discharge pipe L3 respectively.
[0063] The fire ventilation and smoke discharge system for a station hall of a separated island subway underground station provided by embodiments can effectively decrease the length of the air supply pipe and the smoke discharge pipe, reduce wind resistance and improve air supply and smoke discharge efficiency by respectively providing one smoke discharge sub-system and one air supply sub-system at two ends of each station hall. Compared with the prior smoke discharge for fire at a public area of the station hall in the current subway design, the smoke discharge fan in the station hall can be started when fire occurs, for natural air supply through entrances and exits of the station. However, the separated island station comprises two station halls, and station halls of two sides are of far distance, such that no matter to which side the smoke discharge fan of the public area is arranged, an air pipe needs to pass a long distance for extending to another side, and the air pipe connecting the two sides can only be arranged in a connecting channel of the station halls at two sides (as rock and soil are at other positions). This further increases the length of the air pipe and wind resistance significantly, which are not advantageous for smoke discharge during fire. If fire occurs to one end of the station, air rate of smoke discharge at another end of the station totally wastes, and air supplemented at entrances and exits is not sufficient, resulting in further reduction of smoke discharge efficiency. Moreover, the two stations halls in the separated island station are of far distance, such that it is much more difficult for supplementing air naturally with entrances and exits of the station hall at one side that is not on fire. In embodiments, one air supply sub-system and one smoke discharge sub-system are respectively disposed at two ends of each station hall. Since the area of a single station hall of the separated island station is smaller than that of a public area a conventional island station hall, thus air supply force and smoke discharge force required for the air supply sub-system and the smoke discharge sub-system in embodiments is smaller. While not significantly increasing purchasing cost of equipment, smoke discharge efficiency can be significantly improved by a more elaborate ventilation and smoke discharge mode.
[0064] Further, as shown in Fig. 1, a top between the two smoke-proof partitions of the station hall and a top in the middle of a channel are both provided with a smoke screen respectively, and the air supply pipe and the smoke discharge pipe both extend to the smoke screen. Specifically, the middle of the first station hall Al, i.e. a top between the first smoke-proof partition C1 and the second smoke-proof partition C2 is provided with a first smoke screen D1; the middle of the second station hall A2, i.e. a top between the third smoke-proof partition C3 and the fourth smoke-proof partition C4 is provided with a second smoke screen D2; a top in the middle of the first channel B1 is provided with a third smoke screen D3; and a top in the middle of the second channel B2 is provided with a fourth smoke screen D4. More specifically, the first smoke screen D1, the second smoke screen D2, the third smoke screen D3 and the fourth smoke screen D4 can be fixed or movable smoke screens, which are mainly made of nonflammable materials and mounted under ceilings or floor slabs or hidden in ceilings. Lateral flow of smoke under ceilings of buildings can be effectively blocked through smoke screens and by cooperating with smoke discharge pipes, smoke screens are advantageous to improve smoke discharge effects inside smoke-proof partitions, so as to play a positive role in ensuring people’s lives and properties.
[0065] Further, as shown in Fig. 1, each air supply sub-system comprises an air supply pavilion, an air supply fan, an air supply silencer and an air supply pipe that are connected in order, and each smoke discharge sub-system comprises a smoke discharge pavilion, a smoke discharge fan, a smoke discharge silencer and a smoke discharge pipe that are connected in order.
[0066] Specifically, the first air supply sub-system comprises a first air supply pavilion

[0087] More further, the method further comprises a third fire mode, wherein when fire finders in three adjacently provided smoke-proof partitions alarm, the third fire mode is executed; the third fire mode comprising:
[0088] starting smoke discharge sub-systems of three smoke-proof partitions that alarm, and closing smoke discharge sub-systems of a smoke-proof partition that does not alarm; and simultaneously starting air supply sub-system of the smoke-proof partition that does not alarm, and closing air supply sub-systems of the three smoke-proof partitions that alarm.
[0089] Specifically, the third fire mode is divided into a first second third smoke-proof partition fire mode M9, a first second fourth smoke-proof partition fire mode M10, a first third fourth smoke-proof partition fire mode M11 and a second third fourth smoke-proof partition fire mode M12 according to different smoke-proof partitions.

[0090] If smoke is detected only in the first smoke-proof partition C1, the second smoke-proof partition C2 and the third smoke-proof partition C3 after a fire occurs, the first second third smoke-proof partition fire mode M9 is executed, that is, starting the first smoke discharge sub-system, the second smoke discharge sub-system and the third smoke discharge sub-system for discharging smoke; and simultaneously starting the fourth air supply sub-system for air supply to form an air flow from a region that is not on fire to a region that is on fire, so as to effectively prevent smoke from spreading to a smoke-proof partition that is not on fire.
[0091] More specifically, the specific operations of the first second third smoke-proof partition fire mode M9 are: starting the first smoke discharge fan H1, starting the fourth air valve 14, starting the fifth air valve IS, closing the sixth air valve 16, starting the second smoke discharge fan H2, starting the tenth air valve 110, starting the eleventh air valve I11, closing the twelfth air valve 112, starting the third smoke discharge fan H3, starting the sixteenth air valve 116, starting the seventeenth air valve I17, closing the eighteenth air valve I8, starting the fourth air supply fan E4, starting the nineteenth air valve 119, starting the twentieth air valve 120, closing the twenty-first air valve 121, stopping all other fans and closing all other air valves.
[0092] More further, the method further comprises a fourth fire mode, wherein when fire finders in four smoke-proof partitions alarm, the fourth fire mode is executed; the fourth fire mode comprising:
[0093] starting smoke discharge sub-systems of four smoke-proof partitions, closing air supply sub-systems of four smoke-proof partitions and using an gateway of the station hall for supplementing air.
[0094] Specifically, the specific operations of the fourth fire mode, i.e. a total station hall fire mode M13, are: starting the first smoke discharge fan H1, starting the fourth air valve 14, starting the fifth air valve IS, closing the sixth air valve 16, starting the second smoke discharge fan H2, starting the tenth air valve 110, starting the eleventh air valve 111, closing the twelfth air valve I12, starting the third smoke discharge fan H3, starting the sixteenth air valve 116, starting the seventeenth air valve 117, closing the eighteenth air valve 118, starting the fourth air supply fan H4, starting the twenty-second air valve 122, starting the twenty-third air valve 123, closing the twenty-fourth air valve 124, stopping all other fans and closing all other air valves.
[0095] It should be noted that fire generally starts from a certain smoke-proof partition firstly. It is not necessary to execute other fire modes if timely smoke discharge can be ensured by executing the first fire mode. If timely smoke discharge cannot be ensured by executing the first fire mode, smoke will spread to other smoke-proof partitions that are adjacent thereto. If smoke spreads to a smoke-proof partition of one side only, the second fire mode is executed. If the second fire mode still fails to satisfy smoke discharge requirements, the third fire mode is executed. If smoke spreads to smoke-proof partitions of two sides simultaneously, the third fire mode is directly executed. If the third fire mode still fails to satisfy smoke discharge requirements, the fourth fire mode is executed.
[0096] More further, the method further comprises:
[0097] when smoke spreads to more smoke-proof partitions and causes fire finders of other smoke-proof partitions to alarm in a process that is being executed in a fire mode,
continuing to execute a current fire mode.
[0098] after receiving a feedback signal indicating successful execution of the current fire mode, executing another fire mode with an interval of 10s-60s; or
[0099] after failing to receive a feedback signal indicating successful execution of the current fire mode following 1-2min, directly executing another fire mode.
[00100] Specifically, mature electric control devices are adopted as the air supply fans, the smoke discharge fans and air valves etc. in the ventilation and smoke discharge system, such that feedback signals of four states: starting in place, closing in place, starting, and closing, can be sent to a comprehensive control room. Thus, when a central control room receives “starting in place” signals sent by all electric control devices required for input in correspondence to the current fire mode, and “closing in place” signals sent by all electric control devices that need to be closed, it means successful execution of the current fire mode. In this case, the current fire mode is maintained continuously, and another fire mode is executed after an interval of 10s-60s. If feedback signals of one or some electric control devices are not received or the feedback signals received are not in conformity with the current fire mode in the process of executing the current fire mode, it means possible occurrence of faults to these electric control devices, indicating incomplete success of execution of the current fire mode. Thus, another fire mode is directly executed following 1min-2min. More specifically, a control panel in the comprehensive control room may adopt a PLC control system for real-time collection of operation states of each electric control device and perform central control over starting-closing of each electric control device. Meanwhile, timing instructions can be used to control automatic association between fire modes. In embodiments, a plurality of fire modes are dynamically started by setting an interval starting time. When a fire alarming system defects spreading of smoke to other smoke-proof partitions, the control system may automatically link corresponding fire modes for targeted smoke discharge, so as to effective decrease ineffective smoke discharge.
[00101] With a specific embodiment as an example for description, for example, when the first smoke-proof partition fire mode M1 is being executed, the fire finder in the second smoke-proof partition C2 alarms, in which case the system should continue to execute the first smoke-proof partition fire mode M1. Following 30s of receiving a feedback signal indicating successful execution of the first smoke-proof partition fire mode M1, the system starts execution of the first second smoke-proof partition fire mode M5. If failing to receiving a feedback signal indicating successful execution of the first smoke-proof partition fire mode M1 following 2min during which the fire finder in the second smoke-proof partition C2 alarms, the first second smoke-proof partition fire mode M5 is executed directly.
[00102] More further, as shown in Fig. 2, the ventilation and smoke discharge system further comprises a fire mode operation dial 10, the fire mode operation dial 10 being integrated with a start button 20 for executing a fire mode. The method further comprises: when an emergency situation of fire occurs to a station hall, starting a corresponding fire mode by the start button 20. Specifically, the fire mode operation dial 10 can be an integrated back panel (IBP in abbreviation), which is placed in the comprehensive control room of the subway station. When an emergency situation of fire occurs to a station hall or a fault occurs to the automatic association starting system, a station worker can manually start a corresponding fire mode according to fire location so as to reduce operation difficulties of the station worker, lower possibility of the station worker’s operational error, speed up starting of the fire mode, improve smoke discharge effects of fire and reduce casualties. The priority of the start button 20 1s higher than the automatic control system.
[00103] Through the above embodiments of the present invention, it can be seen that the present invention provides a fire ventilation and smoke discharge system and method for a station hall of a separated island subway underground station, wherein the fire ventilation and smoke discharge system for a station hall of a separated island subway underground station can effectively decrease the length of the air supply pipe and the smoke discharge pipe, reduce wind resistance and improve air supply and smoke discharge efficiency by respectively providing one smoke discharge sub-system and one air supply sub-system at two ends of each station hall. Meanwhile, the fire ventilation and smoke discharge method divides two station halls into four smoke-proof partitions. When fire occurs to one or more smoke-proof partitions, an air flow from a region that is not on fire to a region that is on fire is formed by starting the air supply sub-systems of the diagonal or adjacent smoke-proof partition. This can effectively prevent smoke from spreading toward a smoke-proof partition that is not on fire. Using an elaborate fire mode can significantly improve smoke discharge efficiency, realize targeted smoke discharge and effectively reduce ineffective smoke discharge.
[00104] It should be noted that the foregoing embodiments are merely intended for describing the technical solutions of the present invention, but not for limiting the present invention. Although the present invention is described in detail with reference to the foregoing embodiments, a person of ordinary skill in the art should understand that they may still make modifications to the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features thereof. However, these modifications or replacements do not depart the substance of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
