Description
Technical field
The present invention relates to tunnel ventilation classes, specifically compound underground ring corridor fire prevention isolation device and method, are applicable in
Fire separation between the quick tunnel of Urban Underground and underground ring corridor.
Background technique
With the national economic development, urban transportation career development is rapid, and City Underground Transportation road construction is also dashed forward therewith to fly
Push ahead vigorously.Underground ring corridor is a kind of novel City Underground Transportation road occurred in recent years, is repaired for connecting each plot garage
Build be located at below road and the underground public passage that is furnished with independent entrance, it is usually annular in shape.
Compound underground ring corridor is often referred to the underground ring corridor combined with the quick tunnel of Urban Underground.The compound underground ring
There is a series of fire fire-fighting in corridor, because the designed driving speed of underground ring corridor is usually 20km/h, and Urban Underground
For the running speed in quick tunnel in 50-60km/h, the two designs fire control smoke exhausting system of the great disparity to tunnel and ring corridor of current speed
System brings problem.
The difference of the fume exhausting type of the quick tunnel of Urban Underground and underground ring corridor will lead to fire smoke and mutually go here and there.Engineering design
The middle fire compartment underground ring corridor is arranged independently of the quick tunnel of Urban Underground, and underground ring corridor is special due to its annular configuration
Property, generally use transversal ventilation system, when fire carries out lateral smoke evacuation, and air flow direction is based on transverse direction；The quick tunnel of Urban Underground
Longitudinal smoke evacuation system is generallyd use under road fire working, the difference of the two fume exhausting type causes the quick tunnel of Urban Underground to occur
When fire, flue gas easily enters underground ring corridor under the action of longitudinal high-speed flow, causes fire spread.Equally, underground ring
When fire occurs for corridor, the flue gas inside ring corridor is easily influenced by the longitudinal air flow in the quick tunnel of Urban Underground, leads to smoke exhaust efficiency
It reduces, effect is deteriorated.
Setting physics is generallyd use to the fire separation in the quick tunnel of Urban Underground and underground ring corridor in traditional design to prevent fires
Roller shutter or water curtain.Using the compound underground ring corridor of physics fire resisting shutter, when fire, fire resisting shutter can really be formed fastly
Effective barrier in fast tunnel and underground ring corridor, but the channel that fire-fighting and rescue vehicle enters scene of fire has also been obstructed simultaneously.It adopts
The compound underground ring corridor being separated with water curtain can solve fire separation simultaneously and ask with what fire-fighting and rescue vehicle passed through
Topic, but need to provide huge fire cistern, to supply the water of water curtain, while also needing to provide for fire water drainage huge
Fire pump room, construction and maintenance cost are big, this is one huge to construction investment economization, engineering design plan (EDP) rationalization
Challenge.
