Abstract
The utility model provides a kind of miniature slip casting closing device, comprises the rubber stopper of plug in slip casting aperture, it is characterized in that rubber stopper is provided with Grouting Pipe and stack, at the bottom of described stack extends the hole of injected hole.Its function is in the time that teeming slurry in rock cave cave is repaired; do not produce additonal pressure; in repair process, joint fissure can not expanded because of cleavage stress, can effectively protect sandstone rock cave cave to withstand on and reinforce the infringement that causes top, cave historical relic information (engraving or mural painting) in repair process because of construction disturbance.
Description
Technical field
The utility model relates to top, a kind of sandstone rock cave cave disease peeling prosthetic device, relates in particular to a kind of miniature slip casting closing device.
Background technology
When crack appears in top, rock cave cave, cave wall, as reinforced not in time, easily peel off and come off, cause the event of hurting sb.'s feelings.Particularly on part sandstone rock cave, have mural painting, as the Dunhuang Caves, they are historical relics, are also tourist attractions, You Keduo, and Ren Liu great, as top, renovation reinforced rock cave cave not in time, once occur that stone drops, not only damages historical relic, and easily causes personal injury.
Current rock mass recovery technique, the general mode that adopts boring pressured post grouting is to infusion and binding material in injected hole and crack, and grouting pressure is generally 0.2Mpa ~ 0.6Mpa.Because grouting pressure is large, in the improvement that is applied to sandstone rock cave shallow peel disease, because slip casting has increased cleavage fracture stress in crack, the aggravation of the disease that often easily causes scaling off even comes off, and causes and repairs infringement.Particularly for the rock cave as historical relic or engraving, top layer occurs that crack easily causes the disease that scales off, because volume and weight is little, high to construction disturbance susceptibility, even if do not adopt slip casing by pressure, as long as in slip casting process, the air in injected hole cannot be discharged, in crack, form additional cleavage stress, easily cause the not full and crack propagation of slip casting to damage.
Summary of the invention
The purpose of this utility model is to provide a kind of miniature slip casting closing device that additional cleavage stress, crack can not be expanded that makes not produce in the slip casting process of top, sandstone rock cave cave disease peeling reparation.
The utility model is achieved like this.A kind of miniature slip casting closing device, comprises the rubber stopper of plug in slip casting aperture, it is characterized in that rubber stopper is provided with Grouting Pipe and stack, at the bottom of described stack extends the hole of injected hole.
Further preferably, described stack connects a negative pressure device.
Further preferably, described Grouting Pipe connects the manual filling gun that advances.
Further preferably, the described manual gun rack that advances filling gun to comprise a upper side opening, manual pushing ram is equipped with in one end of gun rack, and the other end is installed slip casting needle tubing; Dismountable slurry pipe is installed in gun rack, and the piston end of manual pushing ram is positioned at slurry pipe, and slip casting needle tubing communicates with slurry pipe, and the pin place of described slip casting needle tubing is provided with rubber sleeve, and rubber sleeve is close to sealing Grouting Pipe.
Technique effect of the present utility model is: while reparation on top, rock cave cave, can not produce additional cleavage stress, in repair process, joint fissure can not be expanded, and can effectively protect engraving or the mural painting on sandstone rock cave rock mass top layer.By negative pressure device, can further improve repairing effect.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the manual schematic diagram that advances syringe described in the utility model.
The manual pushing ram 10. slip casting needle tubings of 1. rock cave rock mass 2. rubber stopper 3. Grouting Pipe 4. stack 5. negative pressure device 6. rubber sleeve 7. gun rack 8. slurry pipe 9. in the drawings.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, a kind of miniature slip casting closing device, comprise rubber stopper 2, the injected hole aperture of rubber stopper 2 jam-pack rock cave rock mass 1, it is characterized in that rubber stopper 2 is provided with the Grouting Pipe 3 of φ=6.0mm and the stack 4 of φ=2.0mm, at the bottom of described stack 4 extends the hole of injected hole, described stack 4 connects a negative pressure device 5.
Described Grouting Pipe 4 can connect the manual filling gun that advances as shown in Figure 2, the described manual gun rack 7 that advances filling gun to comprise a upper side opening, and manual pushing ram 9 is equipped with in one end of gun rack 7, and the other end is installed slip casting needle tubing 10; The dismountable slurry pipe 8 of the interior installation of gun rack 7, the piston end of manual pushing ram 9 is positioned at slurry pipe 8, and slip casting needle tubing 10 communicates with slurry pipe 8, and the pin place of described slip casting needle tubing 10 is provided with rubber sleeve 6.
