在阐述了破碎岩体中超深测斜孔埋设的技术难点后 ,提出了破碎岩体中测斜孔造孔的“跟浆套钻”工艺以及高质量超深测斜孔埋设的“软管跟管孔底压浆”工艺。这 2种埋设技术的应用使得破碎岩体中测斜孔的埋设深度达到 82 .5 m
After elaborating the technical difficulty of embedment of ultra-deep measured oblique holes in broken rock mass, the paper puts forward the technology of “heel-grouting” and “high-quality ultra-deep diagonal hole buried” Pipe bottom grouting "process. The application of these two kinds of embedding techniques makes the depth of the inclinometer hole in the crushed rock mass reach 82.5 m
