Abstract
The utility model discloses a device for preventing a tunnel secondary lining vault from disengaging, and belongs to the technical field of tunnel construction. The device for preventing the tunnel secondary lining vault from disengaging comprises a grouting pipe and an exhaust pipe. The grouting pipe and the exhaust pipe are fixedly arranged on the vault in the longitudinal direction and are tightly attached to a water-proof layer, a plurality of small holes are arranged on the pipe walls of the grouting pipe and the pipe walls of the exhaust pipe respectively, the grouting pipe stretches out of a secondary lining end head, and the exhaust pipe extends to the secondary lining end head. The device for preventing the tunnel secondary lining vault from disengaging has the advantages that the structure is simple, air in the vault can be fully exhausted during grouting, a fully filled vault with grouting can be guaranteed, the vault can be prevented from disengaging effectively, the secondary lining grouting effect is more dense than a traditional secondary lining grouting, and construction quality is improved greatly.
Description
Technical field
The utility model relates to a kind of prevention tunnel double-lining vault device that comes to nothing, and belongs to tunnel construction technology field.
Background technology
It is the insoluble secondary lining quality common fault of constructing tunnel that vault comes to nothing always.Traditional construction method is that two lining Grouting Pipe are vertically buried underground, buries negligible amounts (only three) underground, and Grouting Pipe spacing is excessive, causes in concreting process, and vault air cannot be got rid of totally, and concrete can not enrich vault, and formation is come to nothing.
Summary of the invention
For the above-mentioned defect existing in prior art, the utility model provides a kind of prevention tunnel double-lining vault device that comes to nothing, and its easy construction, can effectively avoid vault to come to nothing.
The utility model is achieved by the following technical solution: a kind of prevention tunnel double-lining vault device that comes to nothing, it comprises Grouting Pipe and stack, described slurry pipe and stack are longitudinally fixedly installed on vault and are close to waterproofing course, on the tube wall of described Grouting Pipe and stack, all offer some apertures, described Grouting Pipe is stretched out two lining terminations, and described stack extends to two lining terminations.
In the utility model, the Grouting Pipe longitudinally arranging can be carried out abundant slip casting to the gap of arch crown, and the stack longitudinally arranging can fully be discharged the air of vault, and vault is enriched in assurance slip casting completely.
In order to guarantee slip casting and exhaust effect, the spacing between described Grouting Pipe and stack is 3～5cm.
Aperture on described Grouting Pipe and stack tube wall is quincunx distribution.
Described Grouting Pipe and stack are the pvc pipe of Φ 30mm, and the diameter of described aperture is 0.5cm, and the center to center distance of adjacent two apertures is 20cm.
The utility model is simple in structure, in slip casting process, the air of vault fully can be discharged, and guarantees the completely substantial vault of slip casting, effectively prevents that vault from coming to nothing, and more traditional two lining slip casting effects are more closely knit, greatly improved construction quality.In addition, while utilizing the utility model to carry out vault backfill grouting, can synchronize and carry out with lining construction, without setting up separately operation platform, more traditional mortar depositing construction be more convenient, timely, and save time, laborsaving.
Accompanying drawing explanation
Fig. 1 is the boring schematic diagram of the Grouting Pipe/stack in the utility model;
Fig. 2 is the longitudinal section schematic diagram in the utility model specific embodiment;
Fig. 3 is the schematic cross-sectional view in the utility model specific embodiment;
In figure, the 1st, aperture, the 2nd, waterproofing course, the 3rd, space, the 4th, Grouting Pipe, the 5th, cocycle secondary lining, the 6th, the lining cutting of this circulation secondary, the 7th, lining trolley template, the 8th, lining trolley end mould, the 9th, stack.
The specific embodiment
Also by reference to the accompanying drawings the utility model is further described below by embodiment:
As shown in drawings, a kind of prevention tunnel double-lining vault device that comes to nothing, it comprises Grouting Pipe 4 and stack 9, described slurry pipe 4 and stack 9 are all longitudinally fixedly installed on vault, and are close to waterproofing course 2.On the tube wall of described Grouting Pipe 4 and stack 9, all offer some apertures 1, described Grouting Pipe 4 is stretched out two lining terminations, and described stack 9 extends to two lining terminations.
In the present embodiment, described Grouting Pipe 4 and stack 9 are the pvc pipe of Φ 30mm, two tube pitch 3～5cm.Aperture 1 on two tube walls is all quincunx being uniformly distributed, and the diameter of the aperture 1 on tube wall is 0.5cm, and the center to center distance of adjacent two apertures 1 is 20cm.Grouting Pipe 4 and stack 9 are fixedly welded on vault by fixed strip, and fixed strip can adopt splash guard conventional on building site.
When the utility model uses, first make Grouting Pipe and stack, again Grouting Pipe and stack fixed strip are fixedly welded on to vault having hung after splash guard and nonwoven, then concrete is built in assembling reinforcement, after concrete initial set follower head template removing, carries out slip casting.In the time that grouting pressure reaches 0.2Mpa or stack pulp, represent that vault slip casting completes.Vault backfill grouting can be synchronizeed and carry out with lining construction, without setting up separately operation platform, more traditional grouting process is more timely and save time, laborsaving, and more traditional two lining slip casting effects more closely knit.
Other parts in the present embodiment adopt prior art, do not repeat them here.
