Open area determines according to exhaust smoke level and smoke evacuation wind speed.Electronic exhaust opening smoke evacuation wind speed is generally no greater than 15m/s.Due to electronic smoke evacuation
Mouth quantity greatly reduces, and can be very good the unfavorable region for evading structure.
Set jet blower meaning be：Need to control the jet blower of burning things which may cause a fire disaster point upstream and downstream under fire working simultaneously, it is right
Tunnel vertical wind speed is controlled.In the evacuating personnel stage, general upstream wind speed in 1.5m/s, the reverse wind speed in downstream 0.5~
1m/s, concrete numerical value need calculating analysis to obtain.
Vcehicular tunnel described above is segmented emphasis smoke evacuation system, applied to being related to the main hole of a driving and 1 service tunnel
The arrangement in road.Realize in application, generally be arranged in parallel two main hole of driving a vehicle, and service tunnel is arranged at two main holes of driving
Between, i.e.,：Also include the 2nd main hole 8 of driving；The main main hole 5 of the driving of hole 8 and the 1st of 2nd driving is respectively arranged at the two of service tunnel 3
Side；The 2nd main hole 8 of driving is set and main 5 symmetrical vcehicular tunnel of the hole segmentation emphasis smoke evacuation system of the 1st driving.Now, two drivings
Main hole shares the same main smokejack for being arranged at service tunnel, reduces the setting quantity of main smokejack, reduces system
Cost.And when using traditional smoke evacuation system, when there are two main holes of driving, setting one is required at the top of main hole of each driving a vehicle
Individual main smokejack.Thus the novelty of the present invention is also embodied.
