摘要
阐述CK-60型非开挖地下管线铺设钻机先导孔钻进以及扩孔钻进工艺方法,论证钻进压力、给进速度及地层间的相互关系,确定正确的技术参数值。
In this paper, writers expound the technical way of the precursor holedrilling and extending hole drilling about the CK-60 trenchless drill -rig that make the underground passages laying explore the relationship among the drilling pressure, drillingspeed and the soil layer; then determine the correct technological parameters of thedrilling.
