Abstract

The utility model can cut slip casting hole packer and comprises a slip casting pipe connector connected with a slip casting pump, a non mental slip casting pipe connected on the slip casting pipe connector and capable of cutting, a casting fluid hole packing pipe, an inner fixation device and an outer fixation device on the two ends of the slip casting pipe. The slip casting pipe capable of cutting is arranged inside the slip casting hole and a hole packer concreting casting fluid and packing the hole is provided between the inner and the outer fixation devices. The casting fluid hole packing pipe is arranged between a casting fluid filling pipe and a hole packing bag and adopts the non mental casting fluid filling pipe capable of cutting and preventing sparks. The length and the intensity of each component of the slip casting hole packing device capable of cutting can be determined with the consideration of the adhesive force of the casting fluid induration to the casting filling hole walls, the adhesive force of the casting fluid induration to the connecting cast fluid filling pipe and the casting fluid filling pipe capable of cutting, the casting filling pressure and the casting fluid filling and reinforcing area. The slip casting hole packer is characterized by simple structure, capability of cutting, prevention from sparks, convenient use, low cost, great hole packing effects and wide practicality.

Description

Can cut the injection hole sealing device

Technical field

The utility model relates to can cut the injection hole sealing device, is particularly useful for the leading pre-slip casting of high bottle coal, rock stratum stope, driving face, draws out methane, the slip casting when water filling etc. and drill hole wall are broken.

Background technology

High bottle coal, rock stratum stope, driving face are running into geological structures such as tomography, fold, or coal and rock is loose, broken, in back production, tunneling process, need leading pre-slip casting, draw out methane, water filling etc., for prevent to cut Grouting Pipe, water injection pipe produces spark and causes gas explosion, should not produce spark in the process of cutting Grouting Pipe, the cutting Grouting Pipe does not adopt steel pipe, simultaneously, in order to guarantee bigger grouting pressure, connect Grouting Pipe and adopt steel pipe; When drill hole wall is broken, slip casting, draw out methane, water filling etc. is short because of sealed borehole length, slurries, air, water are difficult to sealing of hole from drill hole wall crack seepage.

Summary of the invention

Technical problem: the purpose of this utility model provides and a kind ofly can cut, avoid producing spark, rational in infrastructure, with low cost, handling ease, cut injection hole sealing device easy to use.

Technical scheme: the utility model can cut the injection hole sealing device, it by the Grouting Pipe that is connected with grouting pump, be connected nonmetal Grouting Pipe, slurries hole sealing tube, the internal fixation device and the external fixator that can cut on the Grouting Pipe joint and constitute at Grouting Pipe two, the Grouting Pipe that can cut is located in the injected hole, be provided with the sealing of hole bag that makes the slurry consolidation sealing of hole between the external and internal fixation device, the slurries hole sealing tube is located between Grouting Pipe and the sealing of hole bag; Described nonmetal Grouting Pipe of cutting can be rubber tube or plastic pipe, also can be fibre pipe.

Beneficial effect: the utility model can cut the injection hole sealing device, has taken all factors into consideration to prevent to cut the steel Grouting Pipe and produce spark and cause gas explosion, has adopted the nonmetal Grouting Pipe that can cut, prevent that spark from producing; Take all factors into consideration adhesion stress, the slurry consolidation body of slurry consolidation body and slip casting hole wall simultaneously and be connected Grouting Pipe, the adhesion stress that can cut Grouting Pipe, grouting pressure, grouting and reinforcing scope, determine length and the intensity that to cut each parts of injection hole sealing device; It is simple in structure, can cut, and avoids producing spark, and easy to use, with low cost, sealing of hole is effective, has practicality widely.

Description of drawings

Accompanying drawing is that the utility model can cut injection hole sealing device structural representation.

Among the figure: 1-Grouting Pipe, 2-external fixator, the nonmetal Grouting Pipe of 3-, 4-sealing of hole bag, 5-internal fixation device, 6-hole sealing tube, 7-injected hole.

The specific embodiment

Below in conjunction with accompanying drawing an example of the present utility model is further described:

The utility model can cut the injection hole sealing device; it is by the Grouting Pipe 1 that is connected with grouting pump; external fixator 2; the nonmetal Grouting Pipe 3 that can cut; sealing of hole bag 4; external fixator 5; hole sealing tube 6 is formed; Grouting Pipe 1 the inner is connected with the nonmetal Grouting Pipe 3 that can cut; hole sealing tube 6 is located between Grouting Pipe and the sealing of hole bag 4; internal fixation device 5 and external fixator 2 are located at two of Grouting Pipe; the nonmetal Grouting Pipe 3 that can cut is located in the injected hole 7; external and internal fixation device 5; be provided with the sealing of hole bag 4 that makes the slurry consolidation sealing of hole between 2; slurries enter the country rock deep along the nonmetal Grouting Pipe 3 that can cut; during sealing of hole; slurries are along hole sealing tube filling sealing of hole bag 4; play the sealing of hole effect after the slurry consolidation; can determine sealed borehole length as required, adopt external and internal fixation device 5; 2 determine the length of sealing of hole bag 4, play the effect of protection sealing of hole bag 4 simultaneously.When slip casting or water filling, slurries or water are entered in the coal and rock through Grouting Pipe 1, the nonmetal Grouting Pipe 3 that can cut by grouting pump, and sealing of hole bag 4 length and intensity are determined according to on-site actual situations.

Claims
