Description
Technical field
The present invention relates to tunnel smoke discharging structure technical fields, more particularly to a kind of subway tunnel ventilating system.
Background technique
" continuous length is greater than 60m to " metro design code " (GB50157-2013) the 28.4.4 articles regulation, but is not more than
The running tunnel of 300m and totally-enclosed lane preferably use natural draught system；When unconditionally using natural draught system, mechanical row should be set
Cigarette " causes this end to be frequently present of this currently, the equipment section length that equipment centralized end often occurs in domestic subway station is too long
Continuous length is greater than 60m but no more than 300m and the unconditional running tunnel for using natural draught system, for such running tunnel, mesh
The mechanical smoke extraction scheme that preceding country's subway is widely used has following two:
Scheme one: rail right above the running tunnel adds smoke outlet on road against the wind, makes the smoke outlet added distance should
The horizontal distance of running tunnel is no more than 30m, and smoke outlet form is the normally opened smoke outlet of manual adjustable.When normal operation, institute
Mouth is kept it turning on the smoke outlet and rail added against the wind, is opened station exhaust fan, is added smoke outlet using on rail against the wind road
It distributes when mouth excludes train dwelling against the wind with rail to the heat in tunnel；When in this running tunnel fire occurs for train, open
Station exhaust fan, using add smoke outlet and the rail on rail against the wind road, mouth is discharged fume against the wind.The program implements more convenient, skill
Art difficulty is lower, but the smoke outlet because being added is the normally opened smoke outlet of manual adjustable, and is located at the proximal end in rail road against the wind, is caused
The rail top tuyere air volume for being located at rail road distal end against the wind under normal operation operating condition is substantially reduced, and then leads to the row of station heat-extraction system
The thermal efficiency reduces.
Scheme two: rail right above the running tunnel adds smoke outlet on road against the wind, makes the smoke outlet added distance should
The horizontal distance of running tunnel is no more than 30m, and smoke outlet form is the normally closed smoke outlet of electric adjustable.When normal operation, increase
If smoke outlet remain turned-off, mouth is kept it turning on rail against the wind, open station exhaust fan, against the wind using the rail on rail against the wind road
Mouth excludes to distribute when train dwelling to the heat in tunnel；When in this running tunnel fire occurs for train, station heat extraction is opened
Blower opens simultaneously the normally closed type smoke outlet added, and using add smoke outlet and the rail on rail against the wind road, mouth is discharged fume against the wind.
The program is because the smoke outlet added is closed in normal conditions, is not in that scheme one leads to station heat extraction system like that therefore
The case where thermal discharge efficiency of system reduces；However, leading to its inspection because the electronic smoke outlet added is located exactly at the surface of route
It repairs highly inconvenient.
