Abstract
A kind of tunnel grouting device, it includes three-way elbow, and three terminations of three-way elbow are connected to Grouting Pipe, the first grout outlet and the second grout outlet, valve is provided with Grouting Pipe respectively, and anti-blocking mechanism is provided with the port of the first grout outlet.The utility model can be solved in Tunnel Second Lining Construction, arch crown part often due to discharge pressure not enough and the reason such as concrete gravity produces the inadequate technical problem of cavity, concrete compactness.
Description
Technical field
The utility model belongs to engineering construction device field, particularly a kind of pre-buried grouting device of tunnel vault.
Background technology
Now in Tunnel Second Lining Construction, arch crown part often due to discharge pressure not enough and the reason such as concrete gravity
Produce situations such as empty, concrete compactness is inadequate.Conventional to use pre-buried PVC Grouting Pipes or small steel pipe, the later stage carries out after-teeming slurry, but one
As slip casting effect it is undesirable.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of tunnel grouting device, can solve in the secondary lining in tunnel
Build in construction, arch crown part often due to discharge pressure not enough and the reason such as concrete gravity to produce cavity, concrete compactness inadequate
Technical problem.
In order to solve the above technical problems, technical scheme is used by the utility model：
A kind of tunnel grouting device, it includes three-way elbow, and three terminations of three-way elbow are connected to Grouting Pipe, first respectively
Grout outlet and the second grout outlet, valve is provided with Grouting Pipe, anti-blocking mechanism is provided with the port of the first grout outlet.
Thread is provided with the second grout outlet.
Above-mentioned anti-blocking mechanism is geotextile layer.
Above-mentioned valve is grouting stop-valve.
Using said structure, slip casting steel pipe is connected by the present apparatus by three-way elbow with two-way grout outlet, makes slurries can be from
Fore-and-aft direction injects simultaneously, no slip casting dead angle；Grout outlet parcel geotextile layer prevents slurries and debris from blocking grout outlet；In slurries
Grouting stop-valve is closed after the completion of injection, prevents slurries from spilling；Slurry intensity cuts off exposure secondary lining surface after reaching design requirement
Tube head, tunnel vault position of coming to nothing is injected enough slurries.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is secondary lining filling slip casting cross-sectional view behind；
Fig. 3 is enlarged drawings of the Fig. 2 at B.
Embodiment
Tunnel grouting device as shown in Figure 1, it includes three-way elbow 1, and three terminations of three-way elbow 1 are connected to slip casting respectively
Pipe 2, the first grout outlet and the second grout outlet, valve 3 is provided with Grouting Pipe 2, is provided with the port of the first grout outlet anti-blocking
Fill in mechanism 4.
Thread 5 is provided with the second grout outlet.
The anti-blocking mechanism 4 is geotextile layer.
The valve 3 is grouting stop-valve.
When as shown in Figures 2 and 3, using the present apparatus, using following steps：
1st, three-way elbow, Grouting Pipe, grouting stop-valve etc. are combined into cost grouting device using thread.
2nd, in Second Lining Construction every a segment distance in pre-buried grouting device of arch crown part.
3rd, secondary lining is stripped, and chassis is removed will be injected just by the slurries that design mixture proportion configures by the present apparatus in time afterwards
Space between phase supporting, waterproof layer and secondary lining.
4th, after grouting pressure reaches design pressure, slip casting operation is terminated.
5th, slurry intensity cuts off exposure in the tube head on secondary lining surface in time after reaching design load, is removed only using screw thread
Valve and slip casting tube head are starched, is recycled.
The present apparatus can make tunnel vault position of coming to nothing inject enough slurries.
