Description
Technical field
The present invention relates to tunnel ventilation technical field is and in particular to single file tunnel short parallel pilot tunnel pressure discharge type in a kind of pair of hole leads to
The method of wind and model.
Background technology
Enter into the middle and late stage in 20th century, with the continuous progress of scientific and technical theory and industrial manufacturing level, tunnel leads to
Wind technology is also developed rapidly, successively occur in that transverse ventilation, semi-transverse ventilation, jet blower longitudinal ventilation mode,
Hole is concentrated feeding formula, is concentrated many force ventilation modes such as discharge formula, vertical shaft blow and exhaust, substantially meets dilution car tail
Gas, improves the needs of sanitary standard.
With the raising of each side standard, different problems also immediately come, and the ventilation scale in tunnel gradually have impact on tunnel
Subject construction, its put into loss also increasing, arrange create Highway Tunnel Ventilation System " repair and must rise, can not afford "
Contradiction, has had become as a difficult point of highway industry, and at this stage, the ventilating engineering cost of long highway tunnel is larger, necessarily
The bottleneck of restriction vcehicular tunnel development is become on degree.Extra-long Highway Tunnel ventilation adopts vertical shaft Network Ventilation, wherein sets
Standby and civil engineering costs accounts for the large percentage of total cost, required expense often to square being directly proportional of length of tunnel, and tunnel builds up
Running cost after being open to traffic also pay wages huge, thus explore tunnel ventilation the great economic worth of energy saving optimizing problem and society meaning
Justice.On the premise of meeting Road Tunnel Safety requirement, reduce related electromechanics as far as possible and purchase and run disbursement, or strive
Find optimal equilibrium point between the two, try hard to be safety, science, green, this will be that following vcehicular tunnel construction needs for a long time
Faced by probing direction.
Make a general survey of the differentiation of various countries' highway tunnel ventilation mode, draft type experienced by transversal ventilation in last century middle and late stage
Development course to longitudinal ventilation.Using double holes one-way traffic more than modern major long tunnel, draft type frequently with full jet machine,
The longitudinal ventilation mode of the perpendicular multiple combination such as (oblique) well, axial flow blower.And, explore the wind solving tunnel and transverse passage-way junction
The control of speed change and to control the energy consumption of blower fan in minimum be also those skilled in the art's focus of interest.
Content of the invention
The defect existing for above-mentioned prior art or deficiency, it is an object of the invention to, a kind of pair of hole single file tunnel is provided
The method of the short parallel pilot tunnel pressure discharge type ventilation in road and model.
In order to realize above-mentioned task, the present invention takes following technical solution：
The method of the short parallel pilot tunnel pressure discharge type ventilation in a kind of pair of hole single file tunnel is it is characterised in that the method is in double holes tunnel
The main hole in tunnel in road respectively opens up, outside importing and exporting, the short parallel pilot tunnel that hole main with tunnel is parallel to each other, the entrance of this short parallel pilot tunnel
At three point that the main hole in tunnel is imported and exported, in short parallel pilot tunnel, it is placed with reversible axial flow blower fan；Meanwhile, in double holes tunnel
Garage's transverse passage-way between road and People's Bank of China's transverse passage-way also place reversible axial flow blower fan, are ensureing that two main tunnels, garage are horizontal logical
On the premise of required airflow sum in road and People's Bank of China's transverse passage-way is not more than its maximum allowable ventilation sum, by adjusting reversible axle
Flow type fan ventilation size and make in tunnel unstable airflow everywhere, and the parallel pilot tunnel in the exit by the main hole of double-hole tunnel
At exhaust outlet, the wind in tunnel is discharged.
According to the present invention, the airflow direction in the main hole in described tunnel is consistent with wagon flow direction, and there is Piston Action Wind, tunnel master
There is air-flow between garage's transverse passage-way in hole or People's Bank of China's transverse passage-way and parallel pilot tunnel to exchange, horizontal logical through garage's transverse passage-way or People's Bank of China
Behind road, air quantity is decreased or increased, and flow velocity accordingly reduces or increases, and now just adjusts reversible axial flow blower fan to supplement or to reduce wind
Amount makes wind speed in the main hole in tunnel be unlikely to change too big so that the air quantity in whole double-hole tunnel keeps balance.
Described Piston Action Wind is the air-flow being produced by vehicle motion in tunnel, and Piston Action Wind air force determines according to actual measurement.

There is (turnover air quantity is equal) to whole double-hole tunnel：
Q1+Q3+Q01+qb1+qd1=Q2+Q4+Q02+qa1+qc1
Wherein：Q01、Q02It is respectively the first tunnel main hole I, the piston air quantity in the main hole in the second 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 above-mentioned pair of hole single file tunnel is to be moved by vehicle in tunnel
The air-flow producing, 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) is using band winding type synchronous motor
Adjust rotating speed, or using the axial fan with hydraulic servo type blade dynamic regulation device.Fan blade peace is adjusted 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》, that is, tunnel space uninterruptedly take a breath frequency, not preferably less than per hour 5 times；For the volume of traffic is less or speciality
Tunnel, can suitably increase rate of ventilation using 3～4 times per hour, use the tunnel of longitudinal ventilation simultaneously under fire condition,
