In conjunction with shown in Fig. 1 and Fig. 2, the embodiment of the application provides a kind of dress administered for multilayer goaf grouting
It sets, including Grouting Pipe 10, the first hole packer 20, slip casting tube head 30 and the second hole packer 40 being sequentially communicated.
At least one injected hole 301 being connected to outside, the first hole packer 20 and the second envelope are distributed on slip casting tube head 30
The maximum outside diameter of hole device 40 is variable.
In the technical solution, Grouting Pipe is connected to outside, to be passed through slurry, the first hole packer 20 and the second hole packer 40
Outer diameter increase may be implemented to block hole, and when outer diameter reduces can from hole be detached from move, to realize again
It is multiple to use, reduce cost.
In addition, the first hole packer 20 and the second hole packer 40 can selectively carry out up and down any goaf by movement
Plugging construction, construction efficiency greatly improve, and the pressure that can not only control each goaf is consistent, can also be according to actual conditions
Different grouting pressures is set for different goafs, and reaches the goaf of requirement for structural strength, it can be selective
Without slip casting, operation is flexible.
The device of this case not only overcomes in the prior art " segmentation pore-forming, downstriker segmenting slip casting " and needs to carry out repeatedly
The existing technical problem of high cost of punching；It also overcomes and is applied existing for the prior art " one-step pore-creating, upstriker segmenting slip casting "
The problem of work period.This case simultaneously may be implemented selectively carry out goaf the advantage of slip casting, reach " 1+1 >
2 " effect.
In conjunction with shown in Fig. 3, in one embodiment, the first hole packer 20 is mutually isostructural device with the second hole packer 40,
Respectively include core pipe 201, spring-backed quill 202 and pressurization mouth 203.

It is formed with medium cavity；Pressurization mouth 203 is communicated in medium cavity.
In one embodiment, spring-backed quill 202 uses rubber tube.
In other embodiments, spring-backed quill 202 can also use other elastic materials, as long as can reach certain simultaneously
Elastic, certain intensity and wearability.
In a preferred embodiment, it is passed through gas-pressurized in dielectric cavity body.
In other embodiments, pressurization mouth 203 can also be passed through liquid medium, as long as spring-backed quill 202 can be driven radial
Expansion, medium select this case to be not intended to limit.
In one embodiment, the pressurization mouth 203 of the first hole packer 20 and the second hole packer 40 is communicated in same pressurizer.
In the technical solution, two hole packers are acted on by a pressurizer simultaneously, it is ensured that the first hole packer 20
With the synchronous working of the second hole packer 40, and cost can be reduced.
In one embodiment, the both ends of slip casting tube head 30 screw thread between the first hole packer 20 and the second hole packer 40 respectively
Connection.
In one embodiment, it is connected through a screw thread between Grouting Pipe 10 and the first hole packer 20.
In the technical solution, between Grouting Pipe and the first hole packer 20, between slip casting tube head 30 and the first hole packer 20, note
It starches and is connected using engagement thread between tube head 30 and the second hole packer 40, not only may be implemented quickly to connect, but also combine sealing
Good sealing function may be implemented in pad.
In conjunction with shown in Fig. 4 and Fig. 5, slip casting tube head 30, including tube body 302 is distributed on the tube body 302 and to be connected to outside
At least one injected hole 301 is respectively arranged with check-valves 303 on each injected hole 301.
In the technical solution, check-valves is in normally off, and the only slurry in slip casting tube head reaches setup pressure value
When, it just opens and starts slip casting operation.
This case can enter slip casting tube head by the check-valves of setting to avoid the underground water in goaf, make stopping slip casting
When industry, smoothly slip casting tube head can be removed.
In one embodiment, multigroup injected hole is distributed in about 30 slip casting tube head, and every group of injected hole respectively includes circular array
Multiple injected holes 301 of column distribution, multiple injected hole 301 are located at sustained height.
In the technical solution, the uniform slip casting of surrounding may be implemented in the distribution of injected hole, ensures grouting quality.
In other embodiments, injected hole can be multiple rows of, when for multilayer, it is preferred to use quincuncial arrangement.
The embodiment of the present application also provides a kind of construction method for the device administered for multilayer goaf grouting, including：
S1, drilling, and through upper and lower multiple goafs；
S2, the second hole packer 40, slip casting tube head 30, the first hole packer 20 and Grouting Pipe are sent into drill successively, and by the
Two hole packers 40, which correspond to, to be waited at the bottom plate rockmass in slip casting goaf, and the first hole packer 20, which corresponds to, waits for slip casting goaf
At top plate rockmass；
S3, by pressurizeing, mouth 203 is passed through medium so that spring-backed quill 202 expands, and realizes mined out to certain layer position in drilling
The closure in non-slip casting region above and below area；
S4, the progress slip casting of slip casting goaf is treated；
S5,202 pressure of spring-backed quill is reduced, the first hole packer 20 and the second hole packer 40 is moved to and next wait for slip casting
Goaf repeats step s3 and s4, until slip casting terminates；
S6, it is passed through clear water from Grouting Pipe, the slurries in Grouting Pipe is squeezed into goaf.
At the end of slip casting, it is also filled with slurry in Grouting Pipe, hole packer and slip casting tube head, if directly pulled out Grouting Pipe
Go out cleaning, then at least there is problem：
One, slurry density is high, and weight is big, and there are problems that slurry waste；
Two, Grouting Pipe is removed from goaf there are the regular hour, and slurry is easy to solidify in the duct, it is difficult to clear
Reason or even Grouting Pipe are cancelled.
In the technical program, at the end of slip casting, slurry can be squeezed by goaf by injected clear water, on the one hand, no
The waste of slurry can be caused, on the other hand, the timely cleaning to pipeline may be implemented, it is at low cost, it is easy to operate.
Another, when slurry is squeezed into goaf by clear water, is also possible to prevent since slip casting hole site is provided with check-valves
The slurry in goaf enters pipeline, ensures that pipeline keeps cleaning.
The device of the invention can carry out " one-step pore-creating, upstriker segmentation suitable for the multilayer goaf being superimposed up and down
Slip casting ".
Operation principle is：It is punched next time by upper so that then multiple goafs pass through the first hole packer through connection
The hole up and down in specific a certain goaf is blocked with the second hole packer, is finally passed through slurry, driving slurry from Grouting Pipe again
Material enters goaf from injected hole.
In conclusion the technical advantage of the present invention includes at least：
1, primary punching is only needed, it is primary to realize to multiple then by the movement of the first hole packer and the second hole packer
The slip casting in goaf works, and reduces punching number and stand-by period, construction cost is low, efficient, short time limit；
2, selective as needed slip casting can be carried out to specific goaf；
3, the grouting pressure in each goaf can be adjusted according to the depth in each goaf, to effectively control slurries
Diffusion length reduces construction cost on the basis of meeting construction quality.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that：Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
Row equivalent replacement；And these modifications or replacements, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
