The self-reinforcing inner self-closing pressure-controlling deep hole-sealing grouter comprises a grouting pipe, wherein an external rubber sleeve is sleeved on the grouting pipe, one end of the external rubber sleeve is arranged on a conical sleeve in an abutting mode, the other end of the external rubber sleeve is provided with a pressing pipe in a pressing mode, the outer side of the pressing pipe abuts against a nut, a grout inlet sleeve pipe is fixedly arranged on the inner wall of the grouting pipe, a piston connection piece is arranged inside the grout inlet sleeve pipe in a matched mode, a non-return plug is arranged at the other end of the grout inlet sleeve pipe in a matched mode, a spring is arranged at the rear side of the non-return plug in a pressing mode, a check ring is arranged at the rear side of the spring in a pressing mode, and a grout expanding hole is formed in a lateral wall of a grout outlet of the grouting pipe. The self-reinforcing inner self-closing pressure-controlling deep hole-sealing grouter is widely applied to support roadways and tunnels of a coal mine, and has the advantages of being convenient to install, low in production cost, good in grouting effect, large in sealing hole depth range (400-600), capable of achieving self-reinforcing, inner self-closing and pressure control, and applicable to rock surfaces at any angle.
Description
Technical field
The utility model belongs to mining machinery, exactly is a kind of solid certainly interior dark sealing of hole slurry casting machine of self-closing pressure control that slurries is injected into rock mass, coal body.
Background technology
Anchor notes technology is a kind of new support technology in the colliery tunnel support of developing in recent years, and it inserts roadway surrounding rock with the grouted anchor bar of hollow, and injects the concrete slurries, so that the rock mass physical modification.Be accompanied by the development of technology, for very easily broken soft rock, bolt-grouting support has begun to inject the slurries that have pressure, and it is very inconvenient to use existing grouted anchor bar to inject the slurries that have pressure, is difficult to effectively to overcome slurries and leaks.In addition, after existing grouted anchor bar is inserted rock mass, because the existence of pressure comes off easily.What is more important, along with going deep into of coal mining, soft stratum is more and more common in the tunnel, and soft stratum often outside rock matter is extremely soft, and deep rock matter is harder, and so just the deep layer to grouted anchor bar has fixedly proposed severe problem.
The utility model content
The purpose of this utility model be to provide a kind of easy for installation, cost of production is low, seal depth bounds big (400～600), can be from the slurry casting machine of solid, interior self-closing, pressure control.
For achieving the above object, the utility model is taked following design scheme:
The dark sealing of hole slurry casting machine of self-closing pressure control in solid, include Grouting Pipe, be set with external rubber sleeve on the described Grouting Pipe, external rubber sleeve one end overhead is on tapered sleeve, the external rubber sleeve other end is pressed to be equipped with and is compressed pipe, compress the pipe outside roof pressure nut is arranged, be fixed with into slurry sleeve pipe on the Grouting Pipe inwall, advance to starch and be combined with the piston brace in the sleeve pipe, advance to starch the sleeve pipe other end and be combined with the check plug, side pressure is equipped with spring behind the check plug, and side pressure is equipped with back-up ring behind the spring, and the grout outlet sidewall of Grouting Pipe is provided with the slurries diffusion hole.
Be provided with packing ring between the external rubber sleeve of the described Guan Yuqi of compressing both sides, the nut.
Described advance to starch between sleeve pipe and the Grouting Pipe fix by trip bolt.
The utility model should comprise a Grouting Pipe from the solid interior dark sealing of hole slurry casting machine of self-closing pressure control, have injected hole on the slip casting tube wall, the difference of itself and existing grouted anchor bar is, Grouting Pipe is built-in with piston, piston connects to form successively by advancing to starch sleeve pipe, piston brace, check plug, spring, back-up ring etc., is provided with tapered sleeve and external rubber sleeve at distance grouting port 400～600 places.
By above-mentioned design scheme as can be seen, before slip casting, screw nut, so that external rubber sleeve spreading is realized dark sealing of hole and solid certainly, when band mud jacking liquid injected, slurries promoted check plug and spring, and pipeline is unimpeded, when stopping slip casting, spring promotes the check plug and blocks into slurry sleeve pipe, has so just realized automatic shutoff injected hole, and the slurries that have pressure can not leak.Therefore, the utility model is specially adapted to soft stratum injection band mud jacking liquid in the tunnel, and is simple in structure, easy to use.
Description of drawings
Fig. 1 installs preceding free state figure for the utility model.
Fig. 2 is the utility model working state figure.
Number in the figure be 1. Grouting Pipe, 2. nut, 3. packing ring, 4. external rubber sleeve, 5. tapered sleeve, 6. trip bolt, 7. the slurries diffusion hole, 8. the piston brace, 9. advance to starch sleeve pipe, 10. check plug, 11. springs, 12. back-up rings, 13. pins, 14. compress pipe.
Below in conjunction with drawings and Examples the utility model is described further.
The specific embodiment
Referring to accompanying drawing, the dark sealing of hole slurry casting machine of self-closing pressure control in solid, include Grouting Pipe 1, be set with external rubber sleeve 4 on the Grouting Pipe 1, external rubber sleeve 4 one end overheads are on tapered sleeve 5, external rubber sleeve 4 other ends are pressed to be equipped with and are compressed pipe 14, compress pipe 14 outside roof pressures nut 2 is arranged, be fixed with into slurry sleeve pipe 9 on Grouting Pipe 1 inwall, advance to starch and be combined with piston brace 8 in the sleeve pipe 9, advance to starch sleeve pipe 9 other ends and be combined with check plug 10, the 10 back side pressures of check plug are equipped with spring 11, and spring 11 back side pressures are equipped with back-up ring 12, and the grout outlet sidewall of Grouting Pipe 1 is provided with slurries diffusion hole 7, compress the external rubber sleeve 4 of pipe 14 and its both sides, be provided with packing ring 3 between the nut 2, advance to starch between sleeve pipe 9 and the Grouting Pipe 1 fixing by trip bolt 6.
Grouting Pipe 1 adopts hard material, when band mud jacking liquid injects, promote to move behind the check plugs 10 by advancing to starch sleeve pipe 9, Grouting Pipe is in the open mode slurries and evenly flows in the country rock that Grouting Pipe 1 inserts by the slurries diffusion hole, plays glued breaking surrounding rock, reduces the effect of country rock internal stress.Among the embodiment, advance to starch and be with piston brace 8 in the sleeve pipe 9, check plug 10 is attached to into slurry sleeve port, and slurries flow through from advancing to starch in sleeve pipe 9 hollow tubes.Embodiment also is equipped with external rubber sleeve 4 at Grouting Pipe 1 outer wall, external rubber sleeve 4 usefulness nuts 2, compress pipe 14, packing ring 3 and the tapered sleeve 5 that is fixed on Grouting Pipe 1 outer wall fixing.When Grouting Pipe 1 was inserted in the rock mass, external rubber sleeve 4 can not come off Grouting Pipe because of the tight interlock of its expansion force and country rock, reached certainly fixedly purpose, was fit to inject band mud jacking liquid more.
The utility model is widely used in the supporting in coal mine roadway, tunnel, have easy for installation, cost of production is low, slip casting effect good, seal depth bounds big (400～600), can be from solid, interior self-closing, pressure control, and be applicable to the advantages such as scar of various angles.
