Description

A kind of simple and effective rough stone block priming by vacuum bracing means and using method thereof
Technical field
Under the invention belongs to a kind of vacuum condition, reperfusion reinforcement adhesive is injected device and the using method thereof that rough stone block crack reinforces rough stone block.
Background technology
Rough stone block, especially Dali Waste stone material, not only there are many cracks, hole in inside, if not encapsulating is reinforced, when sawing becomes hair plates, is often broken into rubble, causes economic loss but also waste valuable rock material resource.Existing enhancing perfusion technology can reinforce connectivity crack and hole, and non-penetrating property crack and hole are not discharged because of the air in crack, and adhesive is difficult to enter, and have impact on consolidation effect.Priming by vacuum is reinforced, and by encapsulating again after vacuumizing, adhesive can enter in non-penetrating property crack and hole and go, and has superiority in the famine material reinforcing of non-penetrating property crack, hole prosperity.But, the prior art existing defects that priming by vacuum is reinforced, one is use vacuum tank and larger vavuum pump, and one-time investment is more; Two is that rough stone block size is lack of standardization, and is larger-size rectangle, easily causes the waste of adhesive; Three be must repeatedly encapsulating, vacuumize, operation comparatively bother, need to be improved.
Summary of the invention
In the object of the present invention, be to overcome prior art weak point, a kind of simple and effective rough stone block priming by vacuum bracing means and using method thereof are provided.
