摘要
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
After expatiation of the technical difficulties in laying very deep inclinoholes in crumbled rock mass, this paper introduces the method of sleeve drill alternated from grouting to drill hole and the method of grouting by hose pipes bound to inclinopipe from the bottom of high quality very deep inclinohole. Application of both methods helps increase the depth of inclinohole to 82.5 m in crumbled rock mass.
