Description
Technical field:
The utility model belongs to constructing tunnel field, is especially a kind of quick grouting device of assembling anchor pole.
Background technique:
In suspension roof support construction, slip casting is essential process, and currently, the deficiency of grouting construction process, is to restrict
One of anchor system performance, anchor-holding force of anchor bolt and critical issue of construction speed, are mainly reflected in the following: 1, slurry reflux
The problems such as, cause the turgor of slip casting insufficient, it is difficult to give full play to the anchoring effect of full grouted anchor pole；During slip casting by
Exist to be easy to cause in slip casting pipe pressure and be embedded to Grouting Pipe and move back and forth, form gas leakage, running pulp phenomenon, grouting pressure cannot expire
Foot requires, and slip casting plumpness around the body of rod is caused to be extremely difficult to design requirement；Simultaneously as gravity causes in certain positions
Slurry stream is lost inside spare anchor bar, to influence the slip casting effect of anchor pole.2, under severe construction environment, operator will reach rule
The construction quality of model, technical operation difficulty are larger；Such as in Tunnel construction, bolt grouting operation is to guarantee construction
An important ring for quality, especially in the case where encountering broken loose weak country rock, it is desirable that country rock section is early closed, and is formed as early as possible
Load -carring arch is effectively to control deflection.Laying orientation according to tunnel anchor pole often has high altitude operation, and slip casting pressure such as vault arch wall
Power is big (being not less than 2.0MPa), when practical mortar depositing construction, it is desirable that each injected hole manual control slip casting entrance, worker's labour are strong
Degree is big, and operation level is difficult to ensure, while construction efficiency is extremely low；3, it by taking Tunnel is constructed as an example, is limited to existing
Bolt grouting structure, at present grouting with plunger are as follows: prepare-connect casting head-booting-shutdown；Each construction location repeats operation, is connecing note
Slurry head and slip casting machine position respectively at least need a people.Since construction environment is narrow, it can not accomplish multiplexing kind concurrent construction, slip casting
Subsequent handling is seriously affected, working efficiency is low, and cost of labor has room for improvement.
Utility model content:
Technical problem to be solved by the utility model is to provide a kind of quick slip castings of assembling anchor pole easy to operate
Device, for the assembling quick grouting device of anchor pole while improving bolt grouting quality, the labour for reducing slip casting worker is strong
Degree realizes rapidly and efficiently mortar depositing construction, reduces labor and materials machine cost, the operation of grouting with plunger is made to be easier to realize standardization, from
And guarantee anchoring effect.
The technical solution of the utility model is to provide a kind of quick grouting device of assembling anchor pole, including hollow
Anchor rod body, grouting stop-valve and Grouting Pipe, further include inside and outside silk connector, variable diameter bidirectional joint and quick union, wherein anchor pole
Body of rod rear end is connect by inside and outside silk connector with grouting stop-valve, and grouting stop-valve is connected by one end of variable diameter bidirectional joint and quick union
It connects, the quick union other end connect setting with Grouting Pipe.
After using the above structure compared with prior art, the utility model has the advantage that since its structure only includes
Anchor rod body, grouting stop-valve and each connector can avoid slurry reflux, guarantee grouting pressure and slip casting turgor, be conducive to abundant
Play the anchoring effect of full grouted anchor pole；And its assembly is simple and fast, and in mortar depositing construction process, filling adaptor and slip casting are set
Standby place, manual operation are easy, it is easier to guarantee every bolt grouting quality, greatly improve construction efficiency；And each connection structure
Easy disassembly is to be detachably connected, and reduces the labor and materials machine consumption in mortar depositing construction process, connector is reusable, with tunnel
For, drilling and grouting with plunger can be parallel.
Preferably, anchor rod body rear end is threadedly coupled with inside and outside silk connector.
Preferably, the front end of anchor rod body is protruded into drilling and is approached to its bottom.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, a kind of quick grouting device of assembling anchor pole, including hollow anchor rod body 3,4 and of grouting stop-valve
Grouting Pipe 5 further includes inside and outside silk connector 6, variable diameter bidirectional joint 7 and quick union 8, wherein 3 rear end of anchor rod body passes through interior
Outer silk connector 6 is connect with grouting stop-valve 4, and grouting stop-valve 4 is connect by variable diameter bidirectional joint 7 with one end of quick union 8, is connect fastly
First 8 other end connect setting with Grouting Pipe 5, is connect by Grouting Pipe 5 with such as slip casting machine of grouting equipment 9, realizes slip casting.
It is all that dismountable connector is connected to due to anchor rod body and grouting stop-valve, between Grouting Pipe, through cleaning after disassembly
It can Reusability.Anchor rod body rear end is threadedly coupled with inside and outside silk connector, and anchor rod body front end outer peripheral surface has external screw thread
Setting.It should be noted that inside and outside silk connector 6, variable diameter bidirectional joint 7 and quick union 8 are commercially available mark product, without special knot
Structure requirement, without special.
In use, after the completion of to 1 armature boring of tunnel surrounding, the front end of anchor rod body is located in drilling 2 and to its bottom
It approaches, 3 rear end of anchor rod body is spirally connected fixation by inside and outside silk connector 6 and grouting stop-valve 4, and 5 one end of Grouting Pipe passes through quick union 8
It is connect with bore one end of variable diameter bidirectional joint 7, the bore other end of variable diameter bidirectional joint is connect with grouting stop-valve 4, forms slip casting
Channel, anchorage length are not less than 50cm as far as possible.Then Grouting Pipe is connect with grouting equipment and carries out slip casting, to can after the completion of slip casting
When dismantling, the inside and outside silk connector of anchor rod body rear end is separated with anchor rod body disassembly.
The apparatus structure is simple, convenient for disassembly and assembly, and using effect is good.Specifically, it can avoid slurry reflux when slip casting, guarantee note
Pressure and slip casting turgor are starched, conducive to the anchoring effect for giving full play to full grouted anchor pole；And its assembly is simple and fast, note
