Description
Technical field
It the utility model is related to a kind of Grouting Pipe, and in particular to termination friction expanding fluid filling tube.
Background technology
The development work of underground coal mine, is acted in tunneling process by mine pressure, and roadway surrounding rock produces broken, plasticity
Circle scope constantly increases, and original prop can not be supported effectively, and tunnel needs frequently to overhaul.Therefore, to tunnel
Country rock body carries out grouting and reinforcing, can be cementing integral by broken rock mass, so as to improve bearing capacity of the wall rock, reduces and overhauls frequency
Rate, and existing Grouting Pipe, installation is complicated, and cost is higher, and reliability is low, it is impossible to meets field demand.
Utility model content
To solve the technical problem that traditional Grouting Pipe is cumbersome, function is single and cost is higher in the mining process of colliery,
The utility model discloses termination friction expanding fluid filling tube.
In order to solve the above technical problems, the utility model uses following technical scheme：
Termination rubs expanding fluid filling tube, including Grouting Pipe, expansion sleeve and extension tube attached, at the port of described Grouting Pipe one end
Provided with pallet, sealing gasket is provided between pallet and Grouting Pipe, the other end of Grouting Pipe is provided with thread head, set on the pipe shaft of Grouting Pipe
There is injected hole；Expansion sleeve and thread head are connected by rope of pulling back, and expansion sleeve is provided with antislip ring, on the pipe shaft of expansion sleeve
Provided with opening, on the one hand the cooperation of expansion sleeve and thread head makes Grouting Pipe and drilling combination closer, on the other hand work as construction
During completion, Grouting Pipe can be pulled out by rope of pulling back and expansion sleeve carries out secondary use.
The pallet is provided with and screws handle, screws handle and is provided with skid-proof rubber, fixing card is provided with the outside of pallet.
The interior caliber of the expansion sleeve is slightly less than the external diameter of thread head, after thread head is screwed into expansion sleeve, in screw thread
In the presence of head, expand in sleeve inlay bur hole, antislip ring increase expansion sleeve and the frictional force of drilling, make the two chimeric tighter
Close, the inner tube of expansion sleeve is provided with anticollision layer, the service life of the setting increase Grouting Pipe of anticollision layer.
Described rope of pulling back is steel wire rope.
The beneficial effects of the utility model are：Expansion sleeve in the utility model is squeezed after expansion, in antislip ring
In the presence of Grouting Pipe fixed be additionally provided with rope of pulling back in the borehole, on expansion sleeve, after slip casting is completed, can pass through to pull back and restrict
The utility model is subjected to recycling, grouting method is simplified, reduces grouting cost, improves slip casting efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the profile of expansion sleeve.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As Figure 1-Figure 2, the utility model discloses termination friction expanding fluid filling tube, including Grouting Pipe 6, expansion sleeve
3 and extension tube attached 12, pallet 9 is provided with one end port of Grouting Pipe 6, and sealing gasket 8, slip casting are provided between pallet 9 and Grouting Pipe 6
The other end of pipe 6 is provided with thread head 5, and the pipe shaft of Grouting Pipe 6 is provided with injected hole 7；Expansion sleeve 3 is with thread head 5 by pulling back
Rope 4 is connected, and expansion sleeve 3 is provided with antislip ring 2, and the pipe shaft of expansion sleeve 3 is provided with opening 1, expansion sleeve 3 and thread head 5
Cooperation on the one hand make Grouting Pipe with drill combination it is closer.
Expansion sleeve in the utility model is squeezed after expansion, and Grouting Pipe is fixed on into drilling in the presence of antislip ring
In, rope of pulling back is additionally provided with expansion sleeve, after slip casting completion, the utility model can be reclaimed by profit again by rope of pulling back
With simplifying grouting method, reduce grouting cost, improve slip casting efficiency.
The pallet 9 is provided with and screws handle 10, screws handle 10 and is provided with skid-proof rubber, the outside of pallet 9 is provided with fixing card
11。
The interior caliber of the expansion sleeve 3 is slightly less than the external diameter of thread head 5, after thread head 5 is screwed into expansion sleeve 3,
In the presence of thread head, in the insertion drilling of expansion sleeve 3, antislip ring 2 increases Grouting Pipe and the frictional force of drilling, makes the two chimeric
It is closer.
The opening 1 is tooth form opening.
Described rope 4 of pulling back is steel wire rope.
The course of work and application method of the present utility model：
First, after expansion sleeve 3 being gently enclosed on into thread head 5, Grouting Pipe 6 is inserted into drilling, rotation screws handle 10,
Expansion sleeve 3 is set to be mutually twisted with Grouting Pipe 6 by thread head 5, because the internal diameter of expansion sleeve 3 is slightly less than the thread head of Grouting Pipe 6
5, by the extruding of thread head 5, expansion sleeve 3 produces expansion, and firmly blocks in the borehole, accesses slip casting flexible pipe 12 afterwards
Slip casting is carried out, after the completion of slip casting, rotates backward and screws handle 10, expansion sleeve 3 is separated with Grouting Pipe 6, Grouting Pipe 6 drops swollen
Expansion set pipe 3, expansion sleeve 3 can be pulled out together.
