Description
Technical field
Face the present invention relates to shield tunnel construction technology field, especially a kind of section of jurisdiction for shield tunnel accident rescue
When support meanss.
Background technology
Current China carries out urban rail transit construction on a large scale, and subway tunnel is mostly using the construction of shield machine method.
Level of ground water is high, complex geologic conditions areas carry out constructing metro tunnel, and water leak accident happens occasionally.Once generation shield is saturating
Water accident, may result in water burst in tunnel flooded, shield duct piece it is damaged, even result in whole piece tunnel and destroy, it is likely that can make
Into great economic loss and casualties.
After generation shield water leak accident, if measure is taken not in time, breakthrough control is bad, it is likely that cause accident to be entered
One step expands.Nearby the section of jurisdiction outside soil body is emptied to ultimately result in shield tail, tunnel duct piece at the shield tail destruction and gradually to
After develop, can seriously cause whole piece tunnel to collapse.There is no solution direct well currently for segment damage problem, generally
The method for being utilized in shield machine rear certain distance casting concrete dam body is blocked, while to water filling in closure section,
So that tunnel external and internal pressure reaches balance, the periphery soil body and tunnel structure reach stabilization.
But shield tail nearby cannot be directly supported section of jurisdiction using the method for casting concrete dam body, and also had a lot
It is not enough：First, staff in tunnel must all be withdrawn from during casting concrete dam body, cause scene to lose the scope of operation, it is impossible to again to oozing
Leak source is blocked.
2nd, concrete dam body pours overlong time, and dangerous situation can be caused further to expand, and cause damage increasing.
3rd, it is not direct enough to tunnel duct piece supporting role.Water is filled after the completion of dam body is poured, in tunnel just damaged to tunnel
Play support and stabilization.
Above mentioned problem directly affects the efficiency of speedily carrying out rescue work to shield water leak accident.
The content of the invention
The present invention is intended to provide a kind of form an inflation annulus by fast aeration, it is close to tunnel inner wall, reaches to tunnel
Road section of jurisdiction support and stablize, it is possible to realize in tunnel initial stage dash, and ensure emergency personnel normally turnover for shield
The section of jurisdiction supporting apparatus that tunnel accident is speedily carried out rescue work.
To achieve the above object, the present invention provides following technical scheme：A kind of section of jurisdiction for shield tunnel accident rescue
Supporting apparatus, including support section of jurisdiction air bag mechanism, the support section of jurisdiction air bag mechanism include inner bag and external capsule, inner bag outsourcing
Cover external capsule；Inner bag inner circumferential is provided with three and fills bleeder port, and three are filled bleeder port and are fixed on inner bag by flanged plate.
As further scheme of the invention：The flanged plate is made up of two-layered steel plates, passes through with inner bag and external capsule respectively
Bolt is fastened.
As further scheme of the invention：The external capsule is provided with and the preformed hole for filling bleeder port cooperation.
As further scheme of the invention：The flanged plate is fixedly connected inner bag, external capsule by anchor bolt.
As further scheme of the invention：The inner bag is in integrally annular.
As further scheme of the invention：The bleeder port that fills is provided with charging connector.
Compared with prior art, the beneficial effects of the invention are as follows：Prop up temporarily the section of jurisdiction for being used for shield tunnel accident rescue
Support arrangement forms an inflation annulus by fast aeration, is close to tunnel inner wall, is reached and tunnel duct piece is supported and is stablized, and can
To realize the initial stage dash in tunnel, and ensure that emergency personnel normally passes in and out, with advantages below：First, can realize to shield
Drive end unit tunnel duct piece is quickly supported, and delays tunnel duct piece deformation and failure process；2nd, after equipment is in place, emergency personnel
Can pass through, not influence rescue face in the range of shield machine；3rd, facility of speedily carrying out rescue work is light, with low cost, and repeatable profit
With.
