Description
Technical field
The utility model relates to a kind of tunnel smoke discharging structure, relates in particular to the anti-smoke discharging structure of distribution area, a kind of subway station.
Background technology
At present, the distribution form that domestic subway station arranges has six kinds of single branch-cut bridge, double crossover, discrepancy field wire, interconnection, single parking line and two parking lines conventionally.Interconnection, go out admission (section) line and generally by jet blower secondary ventilation is set, discharge fume.The existence of distribution causes that two main track tunnels are communicated with, change or the tunnel of tunnel cross-section are in communication with the outside conventionally, distribution the air distribution that has affected interval accident conditions is set.Ventilation smoke exhaust design to distribution place, considers by following: if distribution length is less than a vehicle commander, can include the smoke evacuation of distribution place fire in station tunnel fire purging mode at present conventionally; If distribution length is greater than a vehicle commander, during the breaking out of fire of distribution place, need to take to arrange the ventilation smoke exhaust measures such as jet blower or half transverse row flue.In the distribution of subway station, single parking line and two parking line are all greater than a vehicle commander conventionally, and the length of the single branch-cut bridge of part, double crossover is also likely greater than a vehicle commander, and left and right line is communicated with.Single branch-cut bridge, double crossover are that train and other vehicles (comprising dynamic disabled vehicle) are turned back temporarily, moved flexibly the distribution arranging, and generally one end arranges separately AT STATION.Parking line is that the train of early dispatching a car next day is parked night, or parks and double as the distribution of temporarily turning back for having the standby train in station of passenger flow outburst.It arranges form three kinds: platform both sides arrange single parking line, single parking line is set platform scope and platform both sides arrange two parking lines.
For single branch-cut bridge, it is little that left and right line is communicated with area, little on the air distribution impact of interval accident conditions.If single branch-cut bridge length is less than a vehicle commander, do not need to take secondary ventilation measure; If single branch-cut bridge length is greater than a vehicle commander, need to consider the ventilation smoke exhaust measure at single branch-cut bridge place, ventilation smoke exhaust measure can be half laterally smoke evacuation or longitudinally smoke evacuation.If but adopting longitudinally smoke evacuation, smoke evacuation direction can only, towards a direction tissue, will certainly cause adverse effect to evacuating personnel.
For double crossover, single parking line and two parking line, it is larger that left and right line is communicated with area, for strengthening normal and emergency ventilation effect, generally need to add in distribution area partition wall and secondary ventilation facility.About partition wall, conventionally there is the form that arranges of single partition wall, two partition wall and three partition walls; About secondary ventilation facility, for example double crossover need arrange jet blower or thrust blower fan secondary ventilation conventionally.Single parking line (setting of platform both sides), generally need arrange jet blower or thrust blower fan is set in termination at parking line place; Single parking line (setting of platform scope) need arrange smoke vent conventionally above parking line, and two ends arrange nozzle or thrust blower fan AT STATION simultaneously; Two parking lines need arrange jet blower at parking line place conventionally, or termination arranges nozzle or jet blower AT STATION.
But because double crossover, single parking line and two parking line structure are special, adopt conventional longitudinal ventilation Tobacco Control mode, can make the air quantity of emergency fan greatly increase, and due to the existence of the large section in distribution area, the as easy as rolling off a log flue gas that causes spreads; Jet blower is set in addition and in the future, has potential safety hazard, may affect normal operation; Secondly adopt longitudinally smoke evacuation, smoke evacuation direction can only, towards a direction tissue, can cause adverse effect to evacuating personnel.
Rational partition wall is set in distribution area, rational Tunnel Ventilation System form and smoke vent to be set at top along distribution length direction, to offer a series of smoke vent openings in smoke vent bottom are a kind of effective tunnel Flue Gas Control Technology, how the control important to flue gas such as the size of partition wall form, Tunnel Ventilation System form and smoke vent opening, spacing, arrange best partition wall form, Tunnel Ventilation System form and best smoke vent opening form, spacing is that Tunnel Ventilation System arranges the important step in structure.
Therefore be necessary to design a kind of anti-smoke discharging structure of novel distribution area, subway station, to overcome the problems referred to above.
