Description
Technical field
This utility model relates to technical field of tunnel construction, is specifically related to a kind of for tunnel per-fore pouring liquid with small pipe
Device.
Background technology
In constructing tunnel, V level country rock typically takes advance support, and advance support typically uses grouting with small pipe to weakness
Body country rock carries out pre-reinforcement process, to guarantee to excavate safety.Note must be installed in ductule termination before per-fore pouring liquid with small pipe
Slurry mouth, connects ductule and Grouting Pipe by grouting nozzle.Current grouting nozzle mounting means is all slightly larger than little by one piece of diameter
The circular seal steel plate Site Welding of catheter outer diameter, in the end of ductule, opens the hole of a Φ about 20 in the middle of sealing steel plate,
The grouting nozzle of Φ 20 is welded again at hole.Adding up according to site operation, the time that each grouting nozzle welds with ductule about needs 5
About minute, the construct ductule quantity of each circulation of conventional bore tunnel mostly more than 40, the time of grouting nozzle welding
Being about about 200min, therefore this operation consumes the plenty of time, has had a strong impact on Tunnel Construction Schedule.And each slip casting
Mouth cannot be reused after welding with ductule, causes certain waste, improves construction cost.
Summary of the invention
The purpose of this utility model is to provide a kind of quick grouting device for tunnel per-fore pouring liquid with small pipe, improves
Tunnel Construction Schedule, improves construction benefit, the most reusable, reduces waste, cost-effective.
The technical solution of the utility model is as follows:
A kind of quick grouting device for tunnel per-fore pouring liquid with small pipe, it is characterised in that: include a sleeve, described set
The internal diameter of cylinder, more than the external diameter of advanced tubule, the wall of sleeve is evenly arranged with 3 screws around the same section of sleeve hoop, often
Individual screw is spirally connected a puller bolt；One end nozzle welding of sleeve is greater diameter than the circular sealing steel plate of sleeve outer diameter, institute
State and offer an injected hole in the middle of sealing steel plate, at described injected hole, weld the grouting nozzle of an internal diameter and injected hole equal diameters, institute
State sleeve, injected hole and the axis coinciding of grouting nozzle three.
This utility model greatly reduces the set-up time of per-fore pouring liquid with small pipe mouth.The conventional grouting nozzle single set-up time
Needing about 5min, calculate with the ductule quantity 40 of the conventional each circulation of bore tunnel, the time of grouting nozzle welding is about
For about 200min, and this utility model single set-up time only needs 30s, and 40 grouting with small pipe mouths are installed and only needed about
20min, substantially increases the construction speed of advanced tubule, shortens constructing tunnel circulation time, improves constructing tunnel effect
Rate.
This utility model simple in construction, reusable, after a Grouting Pipe slip casting completes, can pull down and note for the next one
Slurry pipe slip casting, has saved cost, has improve economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model；
Fig. 2 is the structural representation of this utility model another kind embodiment；
Fig. 3 is the occupation mode schematic diagram of a kind of embodiment of this utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, this utility model includes a sleeve 1, and the internal diameter of described sleeve 1 is more than outside advanced tubule
Footpath, sleeve wall is evenly arranged with 3 screws around the same section of sleeve hoop, and each screw is spirally connected a puller bolt 2；Sleeve 1
The welding of one end nozzle greater diameter than the circular sealing steel plate 3 of sleeve outer diameter, offers a slip casting in the middle of described sealing steel plate 3
Hole 4, welds the grouting nozzle 5 of an internal diameter and injected hole equal diameters, described sleeve 1, injected hole 4 and note at described injected hole 4
The axis coinciding of slurry mouth 5 three.
The effect of puller bolt is when this utility model uses, and is fixed by the advanced tubule inserted in sleeve.Fig. 1 institute
In the embodiment shown, it is that one section of sleeve hoop is provided with puller bolt 2.In embodiment shown in Fig. 2, it is around liner ring
Two sections are provided with puller bolt 2, advanced tubule can be made to fix during use relatively reliable.
When this utility model is embodied as, for making advanced tubule front end and sleeve seal, can seal at sleeve 1 inner close fitting
The rubber seal 6 of one annular is set at steel plate 3 inwall.
When this utility model is embodied as, described sleeve diameter determines according to advanced tubule external diameter, current conventional section
The advanced tubule external diameter of Tunnel Design is generally Φ 42, in a specific embodiment of the present utility model, can be selected for wall thickness
Φ 54 sleeve of 3.5cm, length 10-20cm；Sealing steel plate uses the circular steel plate of diameter of phi 56 thickness 1cm, and centre is opened
The injected hole of Φ 20；Grouting nozzle uses the seamless steel pipe of internal diameter Φ 20, and about length 10cm, grouting nozzle exists with sealing steel plate
It is welded to connect at injected hole；Being uniformly arranged 3 screws running through sleeve wall around the same section of sleeve wall hoop, puller bolt uses
3 M16 type high-strength bolts, are screwed onto in 3 screws of sleeve in advance.
During as it is shown on figure 3, this utility model uses, advanced tubule 7 end is inserted in sleeve 1, and it is close to hold out against rubber
3 puller bolts 2 are inwardly tightened by seal 6, make sleeve 1 fix with advanced tubule 7.During slip casting, grouting nozzle 5 is connected note
Slurry pipe can carry out slip casting.After serosity initial set, unscrew puller bolt 2, this utility model is pulled down, can weigh in next circulation
Multiple use.
