Detailed description of the invention
Seeing Fig. 1 to Fig. 5, the present embodiment provides the short parallel pilot tunnel pressure discharge type ventilation model in a kind of double single file tunnels, hole, bag
Include parallel double-hole tunnel, between the main hole of double-hole tunnel, have garage's transverse passage-way and People's Bank of China's transverse passage-way, the tunnel master of double-hole tunnel
The short parallel pilot tunnel that hole main with tunnel is parallel to each other respectively is offered, outside importing and exporting, in hole, and the entrance of this short parallel pilot tunnel is positioned at tunnel master
At three point that hole is imported and exported, in short parallel pilot tunnel, it is placed with reversible axial flow blower fan；Meanwhile, the car between double-hole tunnel
Row transverse passage-way and People's Bank of China's transverse passage-way also place reversible axial flow blower fan.
In the present embodiment, the second reversible axial flow blower fan 2 is placed in the second parallel pilot tunnel 8 exit, and the 3rd parallel pilot tunnel 9 enters
Placing the 3rd reversible axial flow blower fan 3 at Kou, the 4th reversible axial flow blower fan 4, garage are placed by the 4th parallel pilot tunnel 10 import department
Transverse passage-way 11 places the 5th reversible axial flow blower fan 5, and People's Bank of China's transverse passage-way 12 places the 6th reversible axial flow blower fan 6.Main hole, tunnel
Exchange with there is air-flow between transverse passage-way and parallel pilot tunnel, air quantity reduction after garage's transverse passage-way or People's Bank of China's transverse passage-way (or
Increase), flow velocity reduces (or increase) accordingly, the most just can supplement (or minimizing) air quantity with reversible axial flow regulation blower fan and make
In main hole, tunnel, wind speed is unlikely to change the biggest.
In the short parallel pilot tunnel pressure discharge type ventilation model in single file tunnel, double hole, the air quantity in whole double-hole tunnel keeps flat
Weighing apparatus.Wherein, the first reversible axial flow blower fan 1 takes the gas flowed in the first main hole, tunnel I in garage's lateral road 11 away discharge, the
Two reversible axial flow blower fans 2 are flowed into the gas in People's Bank of China's transverse passage-way 12 by supplementing by the first main hole, tunnel I.3rd reversible axial flow
Blower fan 3 takes the gas in 12 second main hole, tunnel II in People's Bank of China's transverse passage-way away discharge.4th reversible axial flow blower fan 4 will supplement
The gas in garage's lateral road 11 is flowed into by main second main hole, tunnel II.
1 to accompanying drawing 4 can be obtained by air balance principle with reference to the accompanying drawings:
For A point: qa1=qa3, qa2=Q1+Q01；
I.e. first reversible axial flow blower fan 1 takes the gas flowed in the first main hole, tunnel I in garage's transverse passage-way 11 away row
Go out.
For B point: qb1=qb2, qa2=Q2+Q01；
I.e. second reversible axial flow blower fan 2 is flowed into the gas in People's Bank of China's transverse passage-way 12 by supplementing by the first main hole, tunnel I.
For C point: qc2=qb2, qc2=Q3+Q02；

Go out.
For D point: qa3=qd1, qc2=Q4+Q02。
I.e. the 4th reversible axial flow blower fan 4 is flowed into the gas in garage's lateral road 12 by supplementing by the second main hole, tunnel II.
Whole double-hole tunnel is had (turnover air quantity is equal):
Q1+Q3+Q01+qb1+qd1=Q2+Q4+Q02+qa1+qc1
Wherein: Q01、Q02Being respectively the first main hole, tunnel I, the piston air quantity of the second main hole, tunnel II, remaining letter is each
Air quantity in passage.
Piston Action Wind in the short parallel pilot tunnel pressure discharge type ventilation model in single file tunnel, above-mentioned pair of hole is to be moved by vehicle in tunnel
The air-flow produced, Piston Action Wind air force determines according to actual measurement.
In the present embodiment, the first to the 6th reversible axial flow blower fan (1,2,3,4,5,6) uses band winding type synchronous motor
Regulation rotating speed, or use the axial fan of the band dynamic adjusting means of hydraulic servo type blade.Fan blade peace is regulated during work
Dress angular adjustment wind supply quantity.
The power of the first to the 6th reversible axial flow blower fan (1,2,3,4,5,6) should be according to " highway tunnel ventilation illuminates
Design specification determines ", i.e. tunnel space is uninterruptedly taken a breath frequency, 5 times the most per hour；Less or the speciality for the volume of traffic
Tunnel, can use 3～4 times per hour, can suitably increase rate of ventilation under fire condition, simultaneously with the tunnel of longitudinal ventilation,
Wind speed of taking a breath in tunnel is not less than 2.5m/s.
First main hole, tunnel I, the second main hole, tunnel II and garage's transverse passage-way 11 or People's Bank of China's transverse passage-way 12 intersection (A, B, C,
D) place can arrange precipitron, the air of intersection (A, B, C, D) is carried out filtration, purification, so can carry to a certain extent
Air quality in main hole, high tunnel.
In view of described reversible axial flow power of fan has certain restriction, so the length in tunnel need to control in allowed band
In.
In the case of breaking out of fire or emergency episode, owing to the power lighting system of parallel pilot tunnel is independent of tunnel master
Hole, the reliable fresh air that can provide again, therefore parallel pilot tunnel can use as a bicycle road multiple line, become personnel,
The emergency evacuation passage of vehicle and rescue passage.Furthermore it is possible to it is horizontal logical manually or automatically to control garage transverse passage-way 11, People's Bank of China
The air switch in road 12, to ensure security of the lives and property when the fugitive life of personnel or rescue.
