Abstract
The utility model discloses a grouting pipe aiming at overcoming the defects of easy sparkle generation, uneven grouting diffusion and grouting pressure reduction in the prior art as a coal mining combine is adopted to directly cut steel tubes. The grouting pipe comprises a grouting pipe joint, a grouting pipe body and an end cap, wherein the front end and the rear end of the grouting pipe body are connected with the end cap and the grouting pipe joint respectively; the grouting pipe body is provided with a grouting outlet; a check ring used for sealing is arranged outside the grouting outlet; and the end cap is tapered. The grouting pipe can be widely applied to the field of grouting on coal mine working faces.
Description
Technical field
The utility model relates to the coal mine work area grouting device, especially a kind of Grouting Pipe.
Background technology
Coal mine work area slip casting in the prior art generally adopts seamless steel pipe as Grouting Pipe, drills through grout outlet on diverse location, slurries is spread in coal body reinforce, and its shortcoming is: coal-winning machine directly cuts steel pipe and is easy to generate spark, has potential safety hazard; Grout outlet causes the slurries diffusion inhomogeneous easily by the cinder shutoff in the boring; If overflow system is set on the grouting pipeline, produce slurry reflux from grout outlet easily, reduced grouting pressure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of Grouting Pipe is provided, and realization can be cut, pressurize and even slip casting.
The purpose of this utility model realizes as follows: comprise Grouting Pipe joint, slip casting body and plug, slip casting body front-end and back-end are connected with plug and Grouting Pipe joint respectively, the slip casting body is provided with grout outlet, and the back-up ring of sealing process has been set outside grout outlet.
In addition, back-up ring is the back-up ring of elastomeric material.
Effect of the present utility model is: guaranteed grouting pressure, the slurries diffusion after the slip casting has evenly improved slip casting diffusion effect and safety, and is easy to use, improved coal mine work area Grouting engineering quality.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, the utility model comprises Grouting Pipe joint 1, slip casting body 2 and taper plug 5, slip casting body 2 front-end and back-end are connected with taper plug 5 and Grouting Pipe joint 1 respectively, according to the grouting and reinforcing scope, the slip casting body is provided with grout outlet 4, the rubber back-up ring 3 of sealing process has been set outside grout outlet 4, has formed closed system.Slip casting body 2 adopts the ABS resin material, and compressive resistance can satisfy instructions for use, the generation of electric spark phenomenon in the time of can avoiding coal-winning machine directly to cut owing to the material reason.
During use, grouting equipment is linked to each other with Grouting Pipe joint 1, under the pressure effect of slurries, grout outlet 4 pulps, rubber back-up ring 3 is opened, slurries boring and country rock in spread, stop slip casting after, rubber back-up ring 3 seals the grouting pressure after the assurance slip casting automatically, and this rubber back-up ring 3 can prevent that scum silica frost from stopping up grout outlet 4 and causing the slurries diffusion inhomogeneous.
