Description

Rock powder guiding device for drilling stone relics Technical Field The utility model relates to the technical field of protection and repair of geotechnical cultural relics, in particular to a rock powder flow guiding device for drilling of the geotechnical cultural relics. Background At present, in the protective investigation and repair construction of stone relics, drilling operation is a necessary technical means for acquiring rock mass structural information and implementing anchoring and reinforcement. However, when the traditional drilling process adopts water drill construction, slurry formed by mixing rock powder and cooling water is easy to flow along the surface of the cultural relics in a disordered way, so that serious consequences are that firstly, the slurry permeates into stone pores to cause mineral component corrosion and salt crystallization diseases, secondly, scaling of the dried rock powder is difficult to thoroughly remove, thereby causing surface texture coverage and color pollution of the cultural relics and seriously affecting the authenticity of the cultural relics. With respect to the related art in the above, the inventors consider that there are the following drawbacks: 1. In the prior art, an annular sponge gasket is adopted to wrap a drill bit to absorb slurry, but practice shows that the method has obvious defects, the sponge material loses tightness after being saturated by water absorption, the leakage rate rises exponentially along with the drilling time, and the construction is difficult to develop.
