旋挖钻进技术作为一种高效优质的钻进方法近年来被广泛应用于工业和民用工程建设中。通过工程实例,采用牙龙钻头和螺旋钻头相互组合,并调整截齿角度,使用低档位、高转速、静动耦合加载的工艺方法,使旋挖钻进硬岩的工效明显提高,取得了较好的工程和经济效益。
Rotary drilling technology as an efficient and high-quality drilling method in recent years has been widely used in industrial and civil engineering construction. Through the engineering example, using the combination of the tooth driller bit and the helical drill bit, and adjusting the angle of the pick, using low-grade bit, high speed, static and dynamic coupled loading process, the work efficiency of rotary drilling into hard rock is obviously improved, Good engineering and economic benefits.
