Description
Technical field
The invention belongs to subway station fire-fighting domains, and in particular to a kind of overall height gate standard subway station rail top row heat
Systematic collaboration platform fire smoke evacuation system.
Background technique
Currently, the platform smoke exhaust scheme that domestic overall height gate (shield door) standard subway station is widely used is to open vehicle
It stands smoke exhaust fan, tunnel blower and the exhaust fan of both ends public area.Station public area smoke exhaust fan passes through platform public area
Smoke discharging pipe is discharged fume, and exhaust fan and tunnel blower then pass through one group of sliding door for opening shield door end door or head and the tail, will
Platform flue gas is by the collaboration discharge of the area station Gui Hang, with satisfaction " metro design code " (GB 50157-2013) " subway concourse to platform
Stair and staircase mouth at have and can effectively prevent the air-flow that flue gas is crept up, and downdraught is no less than 1.5m/s's
Wind speed " requirement.
Since exhaust fan and tunnel blower will cooperate with platform smoke exhaust, it is therefore necessary to open the one of shield door end door or head and the tail
Group sliding door is to ensure that platform public area flue gas can be smoothly discharged by the area Gui Hang to outdoor.Unlatching shield door increases platform and dredges
Personnel fall the risk in row area of entering the orbit when dissipating, and special staff need to be arranged to open assistance management at shield door, to prevent
Personnel are because flue gas block vision falls row area of entering the orbit, and which increase manual operation loads when fire, delay staff in fire
Escape time when calamity.
Summary of the invention
For at least one of prior art the above defects or improvement requirements, the present invention provides a kind of overall height gates
Standard subway station rail top row hot systems cooperate with platform fire smoke evacuation system, and when fire occurs for platform AT STATION, it is public to open platform
The smoke evacuation system of the big system in area altogether；Each 1 exhaust fan and each 1 tunnel blower for opening station both ends simultaneously, pass through unlatching
Multiple (the every sides 4~8) of rail road side against the wind electronic exhaust smoke valve collaboration platform public area smoke evacuation, in the feelings for being not turned on shield door
Under condition, meet the related request of " metro design code " (GB 50157-2013), improves the evacuation peace of passenger or staff
