Description
Technical field
The invention belongs to tunnel and the aeration technology field in underground construction tunnel, more particularly to a kind of traffic tunnel, subway
Or the natural ventilation system and method in underground construction tunnel.
Background technology
Existing tunnel and subway etc. are all whether to lean on air blower and air exhauster to solve in construction or in operation
Certainly ventilating problem, all it was tunnel internal to be aerated using forced exhaust mode, it is necessary to be set in tunnel multiple big in the past
Type ventilating fan.That is, Large Copacity ventilating fan is set at certain intervals in tunnel top, by interim exhaust mode, by tunnel
The foul atmosphere and dust in portion etc. are discharged to the outside.
Ventilating fan needs to be horizontally disposed with along tunnel direction in tunnel top center, it is ensured that the discharge directions of ventilating fan are consistent.
But the method for setting multiple large-scale ventilating fans to be discharged to the outside the air of tunnel internal and dust in tunnel top,
Even if multiple ventilating fans start simultaneously, tunnel internal air can not be also discharged to the outside sometimes.
If traffic tunnel（Operation tunnel）Or underground construction length of tunnel is longer, even if ventilating fan is to tunnel internal air
It is exhausted, inner air can only also move limited distance, and just warp-wise tunnel is overall before next ventilating fan is reached
Diffusion, causes next ventilating fan can not receive the inner air that a ventilating fan is brought, discharges it to outside, this
Sample, ventilating fan can only substantially be such that inner air is circulated on the periphery in the setting field of ventilating fan, cause it is stuffy, together
When the longer blower fan of distance power it is bigger, the quantity of unit is more, and China is the big country in individual more mountain areas, length, the quantity in tunnel
All it is No. 1 in the world, more than 3000 meters of delimitation is super long tunnel only by taking vcehicular tunnel as an example, and China just builds before the end of the year 2012
Into at 441,1984.8 kilometers of cumulative length, 1000-3000 rice long tunnels are 3304.4 kilometers of cumulative lengths at 1944, railway
Tunnel ten thousand metres（10 kilometers）More than for super long tunnel, China just has 70 many places , Sui expanding economy will also be unlimited
Increase, the subway in city is also more and more, increasingly longer, capital expenditure is greatly increased around ventilation problem, leads in operation
Wind expense is also high, by taking the freeway tunnel of mud mountain as an example, 10 kilometers of long tunnels, and 6000 square metres of Ventilator Room, blower fan
Power total amount is 6400 watt thousand, in order to meet the requirement of air quantity, has beaten 4 ventilation inclined shafts again, wherein a most long inclined shaft is exactly
1500 meters, it is exactly 9,340,000 yuan to be often only the ventilation electricity charge, in order to ensure that ventilation uninterruptedly also standby in hole will be more than power of fan
Generator, thus present tunnel ventilation mode not only increase pressure and difficulty of construction to construction investment and return enterprise operation
In add cost, reduce benefit, the year ventilation of every kilometer of mud mountain tunnel takes more than 100 ten thousand yuan.
In addition, existing tunnel piercing and other underground jobs generally press wind and exhausting using machinery strength, run into perhaps
More problems, for example, it is big apart from remote resistance, blasting fume, dust, row is not gone out, cause anoxic blasting fume poisoning etc., this series of problems
Serious hinders construction and operation, and substantial amounts of equipment and substantial amounts of oil, electric energy have been put into order to solve existing ventilation problem
Consumption, though so also fail to it is thorough solve the problems, such as, the disaster such as blasting fume poisoning, anoxic, gas, dust explosion happens occasionally,
Various countries fail to break new road in face of this world's common point problem, simply the nothing in the quantity of equipment, on power, in automation
The input of limit, result are only to see that the unrestricted increase problem of input cannot but solve at all, grow operating cost one and grow again, thing
Therefore constantly occur, it is that thinkable method of ventilation is all done under reality, but it is ineffective, people, which generally both know about, is
The air drag of the Nature gives the difficulty come with road ventilation strip, and the resistance without going to consider the Nature could change into ventilation
Power, adopt the key point how flowing resistance being converted into, useful power is the present invention.
The content of the invention

Footpath and length；
(2) the one end of traffic tunnel 9 sets " L " type natural ventilation system, and blowdown stack 1 and main ventilation intake line 5 is closed
Connection, in the presence of the internal-external temperature difference of traffic tunnel 9, pressure difference, the effect of the suction inlet of main ventilation intake line 5 in negative pressure
Under cigarette, dirt and hot gas is increased automatically, be inhaled into main ventilation intake line 5, discharged by blowdown stack 1, fresh air is from hole
Mouth enters to be combined with the hot-air of vehicle discharge, is produced convection current, the pollution air very first time is discharged from blowdown stack.
As shown in figure 3, a kind of natural ventilation system using traffic tunnel, subway or underground construction tunnel of the present invention
The method of ventilation in underground construction tunnel is：
(1) the diameter of blowdown stack and height and main ventilation intake line 5 are set according to the length of traffic tunnel 9 or subway
Diameter and length；
(2) the interposition of traffic tunnel 9 or subway sets T-shape natural ventilation system, is pushed up in traffic tunnel middle part
Portion's excavating shaft 10, general height more than 30 meters, the upper end of blowdown stack 1 through and out vertical shaft 10 outside, lower end respectively with
The main ventilation intake line 5 of both sides is connected, in the presence of traffic tunnel internal-external temperature difference, pressure difference, cigarette, dirt and hot gas it is automatic on
Rise, after the suction inlets of the two main ventilation intake lines 5 connect respectively with blowdown stack sucks, then discharged by blowdown stack,
Fresh air enters from two holes to be combined with the hot-air of vehicle discharge, is produced convection current, is made the pollution air very first time from discharge
Chimney is discharged.
The present invention can also use and set " L " type gravity-flow ventilation system respectively at the both ends in traffic tunnel or underground construction tunnel
System, its method of ventilation are same as above.
As depicted in figs. 1 and 2, a kind of gravity-flow ventilation using traffic tunnel, subway or underground construction tunnel of the invention
The method of ventilation in the underground construction tunnel of system, it is characterised in that：In underground construction tunnel one end, " L " type gravity-flow ventilation system is set
System, by blowdown stack 1 with main ventilation intake line 5 is closed connects, main ventilation, which is responsible for mouth suction inlet and acted with driving, synchronously to be stretched into
Into underground construction tunnel, all the time at the top of operation field, gas in underground construction tunnel is made by the suction function of suction inlet
In body suction ventilation supervisor 5, discharged by blowdown stack 1.
As shown in figure 4, when traffic tunnel, the super speciality of subway or underground construction tunnel, when buried depth degree is special deep, do not possess vertical shaft
Ventilation condition, while hole is height-limited, can not install major diameter main ventilation intake line 5 and be solved using segmented exhaust method
Super long tunnel ventilating problem, described natural ventilation system using two or more than two blowdown stacks 1 and with blowdown stack 1 one
