Description
Technical field
The utility model belongs to tunnel grouting technical field, more particularly, to pipe canopy and retrusive Grouting Pipe.
Background technology
In constructing tunnel field, it is often necessary to exist rockfill, the defective regions such as layer of sand, mud are constructed, such as city underground
Shallow-depth-excavation tunnel is constructed, for this kind of soft stratum constructing tunnel, often there is great technical difficulty and security risk,
In order to comply with the growth requirement in city, it is ensured that constructing tunnel and structure safety, carry out the big Grouting Pipe in rational tunnel with peripherally
Layer grouting and reinforcing is particularly significant.
Utility model content
The technical problem to be solved by the utility model is to：There is provided it is a kind of for safety, slip casting effect is good, efficient pipe
Canopy and retrusive Grouting Pipe.
The utility model also provides a kind of pipe canopy and retrusive Grouting Pipe, the Grouting Pipe are provided with several in the radial direction
Slurry outlet, several slurry outlets are spaced setting along the Grouting Pipe length direction.
As a further improvement of the above technical scheme, several slurry outlets are along the circumferentially-spaced distribution of the Grouting Pipe.
As a further improvement of the above technical scheme, it is also fixed that the pulp hole location is corresponded in the Grouting Pipe
There is thin-walled, in the slurry outlet circumferential direction, the thin-walled blocks described slurry outlet one end.
As a further improvement of the above technical scheme, the Grouting Pipe includes several sub- tube couplings and several connectors, institute
It states connector both ends to be fixedly connected with two adjacent sub- tube couplings respectively, so that several sub- tube couplings are connected with several connectors
Form the Grouting Pipe.
As a further improvement of the above technical scheme, it is fixedly provided with mini-valve tube in the Grouting Pipe, for the note
It starches pipe and carries out slip casting.
The beneficial effects of the utility model：
The pipe canopy and retrusive Grouting Pipe of the utility model, the Grouting Pipe are provided with several slurry outlets in the radial direction,
Several slurry outlets are spaced setting along the Grouting Pipe length direction, and the Grouting Pipe of the utility model is inserted by Grouting Pipe
Injecting treatment is carried out in geology, slip casting effect is more preferable, more efficient, safe.
Description of the drawings
Fig. 1 is the structural schematic diagram of the Grouting Pipe of the utility model；
Fig. 2 is the left view of the Grouting Pipe of the utility model；
Fig. 3 is the partial schematic diagram of pulp hole site in the Grouting Pipe of the utility model.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
The other embodiment that art personnel are obtained without creative efforts belongs to the model of the utility model protection
It encloses.In addition, all connection/connection relations arrived involved in patent, not singly refer to component and directly connect, and referring to can be according to specific
Performance, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each skill in the utility model creation
Art feature, can be with combination of interactions under the premise of not conflicting conflict.
The utility model provides the Grouting Pipe of a kind of pipe canopy and retrusive, as shown in Figure 1-Figure 3, the slip casting of the utility model
Pipe includes several sub- tube couplings 1 and several connector (not shown)s, the both ends of the connector respectively with two adjacent sons
Tube coupling 1 is fixedly connected, and above-mentioned several sub- tube couplings 1 are connected with several connectors and form the slip casting of an entirety between each other
Pipe.
Grouting Pipe has certain wall thickness, several slurry outlets are offered in the radial direction, in Grouting Pipe in Grouting Pipe
2, and on the length direction of Grouting Pipe, the setting of several slurry outlets 2 interval, on the circumferencial direction of Grouting Pipe, several go out
Hole 2 is starched along Grouting Pipe circumferentially, so that the pulp range of slurry outlet 2 can cover the periphery of Grouting Pipe, in the present embodiment, if
The position of dry slurry outlet 2 is circumferentially distributed at Grouting Pipe two-by-two adjacent 120 degree of three positions respectively.
Corresponding to thin-walled 3 is additionally provided at the position of slurry outlet 2 in Grouting Pipe, thin-walled 3 is along the axial direction of slurry outlet 2
One end of slurry outlet 2 is closed, in this way, ensure before slip casting, Grouting Pipe disposed of in its entirety closed state, before slip casting, tunnel
The soil on periphery can not carry out the inside of Grouting Pipe, ensure that the stability of slip casting process, during slip casting, be generated by slip casting
Pressure can punch through thin-walled 3 so that slurry is diffused into Grouting Pipe periphery by slurry outlet 2, to its periphery carry out grouting and reinforcing,
It has more efficient slip casting effect.
The Grouting Pipe of the utility model further includes mini-valve tube (not shown), and mini-valve tube is fixedly arranged on inside Grouting Pipe, note
The process of slurry is completed by using mini-valve tube, during slip casting, by mini-valve tube can easily control the process of slip casting with
And the pressure of slip casting, it is simple for process, it is relatively reliable.
It is to be illustrated to the preferable implementation of the utility model, but the utility model creation is not limited to institute above
Embodiment is stated, those skilled in the art can also make various be equal without departing from the spirit of the present invention
Deformation is replaced, these equivalent deformations or replacement are all contained in the application claim limited range.
