A kind of double cabin rubber bag apparatus of self-locking aqueous vapor for tunnel flood-fighting
Technical field
The present invention relates to a kind of baffle device for water in Geotechnical Engineering and Tunnel Engineering.More particularly to a kind of quick place
The double cabin rubber bag apparatus of self-locking aqueous vapor for tunnel flood-fighting of the prominent mud problem of water burst in reason tunnel.
Background technology
With the peace in the construction and operation of the exploitation of the underground space, subterranean railway tunnel, urban pipeline passage etc.
Full problem receives much concern.And there is unavoidably water-bearing layer or rock crack developmentally band in these underground pipings institute Jing regions, construction or
The probability of the problems such as seepage, water burst prominent mud occurs during operation is very big, and the flood in rainy season also happens occasionally.Such accident
The characteristics of be sudden, high harmfulness etc., once occur, gently then flood or burial equipment, blocking tunnel, affect construction speed
And construction plan, it is heavy then cause tunnel cave, cause surface collapse, surface structures is collapsed or is destroyed, cause great property
Life security hidden danger.Therefore, timely and effectively processing method such issues that mud prominent for water burst is increasingly subject to interested party
The attention in face.
At present, the region strong for rock crack development or water penetration is run into during constructing tunnel, generally using cast-in-place
Concrete dam body carries out dash and speedily carries out rescue work, and recycles the methods such as grouting to carry out sealing to percolation zone.This method has the disadvantages that:
(1) invest larger;(2) time cycle is long, it is impossible to meet the larger dangerous situation of water burst speed, does not accomplish have water to block up (3) dash knot
Structure removes difficult, causes tunnel to destroy or affects tunnel safety to use.

, there is seepage, gushing in a kind of double cabin rubber bag apparatus of self-locking aqueous vapor for tunnel flood-fighting of the present invention
Water dashes forward situations such as mud, flood pour in down a chimney when needing promptly to speedily carry out rescue work, first from water pocket one end gas injection port by air injection pipe to airbag aeration
To certain internal pressure so as to which expansion fills up whole tunnel cross-section, plays a part of dash.Placement is surveyed in airbag structure dash unidirectionally to let out
Pressure valve, sets the pressure value of unidirectional pressure relief valve, and when hydraulic pressure is more than the pressure value, water is by unidirectional pressure relief valve via pre-
If pipeline flow into water pocket in, so as to keep air bag one survey hydraulic pressure less than setting value and ensure the stability of air bag.Work as water
After capsule is charged completely, defining can resist the water pocket structure of very big horizontal thrust.The structure may insure to continue to increase in hydraulic pressure
The water-retaining capacity and stability (self-locking effectiveness) of frontal air bag when big.With reference to follow-up slip casting it is stifled ooze, the resolution such as draining,
Form fast and effectively resolution.After improvement terminates, the water (gas) in self-locking rubber bag tank is discharged, just can easily reclaim storage
Deposit.
The sitework geological conditions of report offer should be surveyed (including geology bar around according to the ground of early stage during constructing tunnel
Part, water-bearing layer distribution etc.), if head is higher, the self-locking aqueous vapor for tunnel flood-fighting proposed by the present invention need to be adopted
Double cabin rubber bag apparatus.
A kind of selection of the double cabin rubber bag apparatus storage points of self-locking aqueous vapor for tunnel flood-fighting of the present invention will
Meet following condition:1st, distance construction region is nearer;2nd, storage place is totally smooth, no-sundries, facilitates self-locking rubber bag tank
Access;3rd, cannot be to the hurtful sharp objects of rubber bag tank.Furthermore it is ensured that have sufficient, capable of being conveniently and easily taken charging material
(water, gas) and water pipe etc..
When the prominent mud phenomenon of water burst is run into, rapid a self-locking rubber bag tank should be taken out from storage point, be laid on area to be protected
Before section, gas injection port is connected with air blast (air compressor machine), opens charging valve, fast aeration expands air bag, while noting
Whether early warning has reached critical pressure with air gauge siren for observation.Close to after designing using air pressure after rubber bag tank airbag aeration
Charger, and charging valve is closed, now air bag can effectively play dash effect.When external water pressure exceedes unidirectional pressure relief valve
During threshold values, unidirectional pressure relief valve is opened, and water is flowed into water pocket by unidirectional pressure relief valve, aqueduct, emptying valve etc., water pocket by
Gradually it is filled, water pocket produce larger frictional force with tunnel wall under pressure conducting oneself with dignity and charges, can be common with air bag above
Stable dash is played a part of in effect.After airbag aeration is finished, you can start evacuating people and related equipment, carry out follow-up
Slip casting stifled ooze work.
In the case of conditional, when air bag is installed can by air bag by the anchor pole in anchoring joint and tunnel or other consolidate
Determine facility to couple together, further the stability of increase rubber bag tank.
After improvement terminates, self-locking rubber bag tank is sluiced (gas), checked each position service condition and degree of injury, folding
Poststack is under lock and key, convenient to reuse.
