Description
Technical field
The invention belongs to tunnel smoke controlling technical fields, more particularly, to a kind of high hermetic type smoke outlet device.
Background technology
Continuous with the volume of traffic increases and the increasing of running speed, density, in addition the special construction of super long tunnel and
Environmental condition easily causes traffic accident in tunnel and induces the accidents such as fire.And tunnel fire hazard is usually associated with high temperature, flue gas
Suffocate, On The Deterioration of Visibility Over, causes escape difficult and short time inside and outside rescue is hard to reach scene and work of suing and labouring is unfolded.Cause
This, tunnel fire hazard accident often results in casualties, economic loss, property destruction.
Fire causes a main cause of casualties heaviness to be that flue gas fails to detach discharge in time and personnel is caused to stop up
Breath, and tunnel internal space relative closure, smoke evacuation path is limited, and how when fire, which effectively solves smoke evacuation just, becomes reduction personnel and hinder
It dies, the most critical factor of property loss.For this purpose, China《Highway tunnel ventilation Lighting Design specification》Clearly propose：" Design of ventilation
When must take into consideration fire countermeasure, length is more than 1500m and the larger tunnel of the volume of traffic is considered as smoke evacuation measure ".
Usually normal operation phase uses longitudinal ventilation pattern in the tunnel of European and American developed countries' significant proportion, and fire is discharged fume
Then use smokejack central exhaust pattern.It is domestic in terms of the understanding of Tunnel Fire smoke evacuation relative to European and American developed countries,
Not yet cause enough attention, the exploratory stage is also to the research of fire smoke evacuation.
According to《Code for fire protection design of buildings》The regulation that the 12.3.2 articles of GB50016-2014 is more than 3000m for length
And the unconditional urban transportation tunnel longitudinally discharged fume using segmentation, preferably use emphasis fume exhausting type.Which passes through on tunnel top
Smokejack is arranged in portion or side, and the electronic smoke outlet of (usually in 60m or so) setting spaced apart is arranged at smokejack both ends
Flue gas is discharged tunnel, illustrated such as Fig. 1 institutes by smoke exhaust fan, electronic smoke outlet when fire near opened smoke-discharging wind turbine and burning things which may cause a fire disaster
Show.
The smoke outlet being arranged on tunnel field, smokejack at present is generally discharged fume by the Multiblade that atlas number is 07K103-1
Mouth is designed：The smoke outlet is made of multistage blade, and unlatching and the pass of smoke outlet are realized by four-bar mechanism driving blade
It closes.Tunnel smokejack need to generally set one group of smoke outlet every 60 meters, and usually smoke outlet is closed, and fire when fire occurs
Several groups of smoke outlets near point are opened.
But there is big blade gaps area, poor sealing, leak out seriously in Multiblade smoke outlet in actual use
Defect, the electronic smoke outlet inleakage of code requirement is no more than 700m3/h·m2, currently on the market sealing performance preferably produce
Product can control inleakage in 200m3/h·m2Left and right, however it remains more serious air leakage phenomena.Smoke outlet leaks out serious meeting
And cause smoke exhaust fan smoke exhaust efficiency low, for major long tunnel, since smoke outlet is large number of, smoke evacuation system may be caused
System failure, serious harm is brought to tunnel structure and evacuating personnel.
