Description
Technical field
This utility model belongs to municipal administration and vcehicular tunnel technical field and in particular to one kind is two-tube municipal under water and highway is long
The ventilating system of big shield tunnel.
Background technology
The selection of submerged tunnel air vent mode, with length of tunnel, traffic flow, running mode, hole environmental requirement, tunnel
The many factors such as construction method are relevant.The tunnel ventilation mode commonly used at present have entirely laterally, half laterally, longitudinal ventilation mode and vertical
To the smoke evacuation of ventilation+emphasis.
Entirely horizontal and semi-transverse ventilation mode need to arrange special air duct and Ventilator Room, and civil engineering costs investment is big, and the later stage divulges information
Running cost is high, can effectively keep backlayering during fire, but because the air-flow that it provides is horizontal, climing with flue gas in tunnel
Prolong direction vertically it is impossible to effective control flue gas is longitudinally spreading along tunnel.
The traffic that longitudinal ventilation mode can give full play to automobile rises pressure (Piston Action Wind), have good to upstream flue gas control
Effect processed, has good flue gas control effect for normal one-way traffic.But under traffic jam and two-direction road operating mode,
The personnel of the upstream and downstream of burning things which may cause a fire disaster evacuation all in need and vehicle, longitudinal direction is distinguished and admirable to be full of the whole Close Tunnel in burning things which may cause a fire disaster downstream by fire smoke
Domain, the personnel escape to downstream and fire suppression bring very big threat, thus longitudinal smoke evacuation system does not ensure that under burning things which may cause a fire disaster
The safety of wind direction driver and conductor.
Longitudinal ventilation+emphasis fume exhausting type, arranges civil engineering smoke duct in tunnel upper, carries out longitudinal ventilation at ordinary times, can
Pressure is risen with the traffic giving full play to automobile, during fire, carries out emphasis smoke evacuation, by opening the multiple exhaust openings near burning things which may cause a fire disaster, just
Nearly impact flue gas discharged vehicular tunnel via smokejack, reduces to staff in tunnel escape to greatest extent.
Based on this, domestic at present a lot of two-tube under water shield tunnels all employ longitudinal ventilation+point type central exhaust substantially
Scheme.Jet blower divides two sections of arrangements (arranging along tunnel two ends) toward middle part, arranges civil engineering smoke duct in shield section simultaneously
And jet blower, lead to shield section larger.The increase of shield section will bring engineering construction difficulty, construction risk and engineering
The increase of cost, constrains application in submerged tunnel of growing up for the shield method to a certain extent.
Utility model content

Connected smoke evacuation ventilating shaft, is provided with smoke exhaust fan and air-valve in described smoke evacuation ventilating shaft；The middle part of described shield tunnel is indulged along tunnel
To being divided into shield a section, shield b section, shield c section successively, described shield a section, the civil engineering smoke duct area equation of shield c section,
Described shield b section civil engineering smoke duct area is 2/5-3/5, described shield b section and the shield of shield a section civil engineering smoke duct area
The two ends open cut of structure tunnel is secretly buried section and is respectively provided with jet blower.
The more excellent area of described shield b section civil engineering smoke duct is the 1/2 of shield a section civil engineering smoke duct area.
Mutually stagger with civil engineering smoke duct position positioned at the jet blower position of described shield b section, described shield b section
Have overlapping in jet blower and shield a section, the projection of shield c section civil engineering smoke duct transverse section.
The beneficial effects of the utility model are:
1st, submerged tunnel draft type of the present utility model is simple, in conventional longitudinal ventilation+emphasis smoke-discharging and ventilating mode
On the basis of, divide, by jet blower, the method that three sections of arrangements, jet blower position and civil engineering smoke duct position mutually stagger, both
Ensure that ventilation and smoke evacuation functional effect, decrease the dimensional requirement to shield section again, reduce engineering construction difficulty and
Construction risk, has saved engineering-built cost；
2nd, this utility model is applied to two-tube municipal administration and highway shield tunnel under water, and tunnel two ends have open cut and secretly bury
Section.
