Including slip casting pipe, expansion pipe and external hose, the slip casting pipe divide into thread end and trompil end, and the thread end and the expansion pipe of slip casting pipe pass through threaded connection, and the thread end port department of slip casting pipe is equipped with the tray, is equipped with the handle on the tray, is equipped with out grouting holes on the slip casting pipe pipe shaft, expansion pipe pipe shaft one side is equipped with serrated groove, is equipped with the internal thread on the expansion pipe, and expansion pipe one end is equipped with keeps off the thick liquid dish, it is equipped with the rubber circle to keep off between thick liquid dish and the tray, external hose links to each other with the slip casting pipe. The utility model provides an expansion pipe receives extrusion inflation back, can firmly block in drilling to fix the slip casting pipe in drilling, the fender thick liquid dish of expansion pipe bottom can prevent to run the thick liquid, has simplified the slip casting method, has reduced the slip casting cost, has improved slip casting efficiency.
Description
Technical field
The utility model is related to a kind of Grouting Pipe, and in particular to a kind of mining expandable frictional formula Grouting Pipe.
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, install complicated, and relatively costly, reliability is low, it is impossible to meet field demand.
Utility model content
Traditional Grouting Pipe is cumbersome in solve colliery mining process, single function and relatively costly technical problem,
The utility model discloses a kind of mining expandable frictional formula Grouting Pipe.
To solve above-mentioned technical problem, the utility model is employed the following technical solutions：
Mining expandable frictional formula Grouting Pipe, including Grouting Pipe, expansion tube and external hose, the Grouting Pipe is divided into the end of thread
With perforate end, the end of thread and the expansion tube of Grouting Pipe be threaded connection, and the end of thread port of Grouting Pipe is provided with pallet, pallet
Handle is provided with, Grouting Pipe pipe shaft is provided with slurry outlet；The expansion tube pipe shaft side is provided with serrate slot, and expansion tube is provided with interior
Screw thread, expansion tube one end is provided with baffle plate；Rubber ring is provided between the baffle plate and pallet；The external hose and Grouting Pipe
It is connected.
The expansion pipe surface is provided with antiskid particles.
Caliber of the caliber of the end of thread of the Grouting Pipe more than perforate end.
The interior caliber of the expansion tube is slightly less than the outer tube diameter of the end of thread of Grouting Pipe.
The beneficial effects of the utility model are：Expansion tube in the utility model is squeezed after expansion, in serrate slot
Grouting Pipe is fixed in the borehole under effect, expanding the baffle plate of bottom of the tube can prevent running pulp, simplify grouting method, reduce
Grouting cost, improves slip casting efficiency.

Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail：
As shown in Figure 1-Figure 3, a kind of mining expandable frictional formula Grouting Pipe of the utility model, including Grouting Pipe 1, expansion tube 3
With external hose 6,1 point of the Grouting Pipe is the end of thread and perforate end, and the end of thread and the expansion tube 3 of Grouting Pipe 1 are connected by screw thread
Connect, the end of thread port of Grouting Pipe 1 is provided with pallet 5, and pallet 5 is provided with handle 7, and the pipe shaft of Grouting Pipe 1 is provided with slurry outlet 10；
The pipe shaft side of the expansion tube 3 is provided with serrate slot 2, and expansion tube 3 is provided with internal thread, and the one end of expansion tube 3 is provided with baffle plate 4；Institute
State and rubber ring 8 is provided between baffle plate 4 and pallet 5；The external hose 6 is connected with Grouting Pipe 1.The surface of the expansion tube 3 sets
There are antiskid particles 9, increase the friction between expansion tube 3 and body of wall, strengthen Grouting Pipe 1.The end of thread of the Grouting Pipe 1
Caliber of the caliber more than perforate end.The inner side of the expansion tube 3 is provided with screw thread.The interior caliber of the expansion tube 3 is slightly less than slip casting
The outer tube diameter of the end of thread of pipe 1, due to the difference of caliber, is extruded by Grouting Pipe 1, and expansion tube 3 produces expansion, and firmly blocks
In the borehole.
The course of work of the present utility model and using method：
First, expansion tube 3 is inserted into drilling so as to which baffle plate 4 is close to coal and rock wall, afterwards, rubber ring 8 is inserted in swollen
Tube expansion 3 so as to be close to pallet 5, by Grouting Pipe 1 expansion tube 3 is inserted, and by handle 7 Grouting Pipe 1 is rotated so as to logical with expansion tube 3
Cross screw thread to be mutually twisted, due to the difference of caliber, extruded by Grouting Pipe 1, expansion tube 3 produces expansion, and is firmly stuck in brill
Kong Zhong, external hose 6 is accessed afterwards can carry out slip casting.
