Description
Technical field
The present invention relates to tunnel construction apparatus fields, and in particular, to one kind be mounted on formwork jumbo and country rock it
Between stopper structure and its installation method.
Background technology
Road and rail tunnel is built frequently with New Austrian Tunneling Method, and engineering method is as follows：Crown is disposed first, and sprays dry-mixed mortar,
Waterproof country rock is formed, then the preset secondary lining framework of steel reinforcement between formwork jumbo and waterproof country rock, finally by the side of pouring
Formula is in waterproof country rock, the secondary lining side poured in advance（That is construction joint side）Secondary lining is formed between formwork jumbo to pour
Build model（About 12 meters or so of the longitudinal length of mould is closed every time）.At secondary lining model side to be poured, due to having
A large amount of vertical exposed reinforcing bars, Guan Mo are more difficult.
Generally use bar shaped plank is axially blocked along ring tunnel, this conventional method has the following problems：（1）For in template
The stopper structure that the end of trolley is laid with, not only heavy workload（It is laid with a circle and usually requires four 8 hours workloads of people）, remove
The problem of mould is also cumbersome, and there is also heavy workloads；（2）Process of deployment complexity bothers, and not only wastes a large amount of timber（Timber
Recycling rate of waterused is low）, and since to imitate fruit poor for the pass of timber, also easily there is a large amount of hole leak source, especially in reinforcing bar
Place is not easy to seal, and the later stage is needed to use other soft object blocking holes, nonetheless, cannot still avoid the occurrence of cement mortar leakage waste
Problem；（3）Mould is closed using plank, needs to fold middle buried water stop along plank, in Guan Mo, so to easily cause
There is the problem of waterstop location dislocation between pouring model in adjacent secondary lining, does not have due water-stagnating effect；（4）Plank
Splash guard below the easy damaged waterproof country rock of corner, causes tunnel leak hidden danger.
Foregoing problems are existing tunnel construction common problems, asking for leak occur simultaneously for present a large amount of tunnels
Splash guard under topic, with country rock when closing mould, which is destroyed, to have some relations.Also have using steel form as the technical solution of end mould plug,
But there are template heaviness, it is not easy to operate the defects of.Such as utility model patent《A kind of Tunnel Second Lining formwork jumbo plug
Plate》（Application number：201520472105.7 ）A kind of bulkhead installed on formwork jumbo is provided, is fixed by bulkhead
Waterstop, and carry out pass molding and block up, but complexity is designed, while there is also be not easy to bypass the problem of appearing reinforcing bar.
Invention content
For aforementioned problem of the prior art, the present invention provides a kind of plugs being mounted between formwork jumbo and country rock
Structure and its installation method can be by plugs using the resilient characteristic of the blowing pressure and multiple elastomeric layers of inflatable layer
Interlayer structure squeezed tight together, reinforcing bar and waterstop thus can be not only exposed in stopper structure, facilitates Guan Moshi
Work prevents waterstop from misplacing, it can also be ensured that in stopper structure, any gap is not present, avoids occurring in model forming
Spillage, while any damage will not be caused to the splash guard under the country rock of top, potential tunnel leak hidden danger can be eliminated.In addition,
The stopper structure also has the characteristics that easy for assemble or unload, component reuse rate is high, simple in structure and at low cost, convenient for real
Border promotion and application.
