摘要
以施工实践为基础,结合理论分析,提出了一种在岩土锚固工程施工中广泛应用的新型钻探工艺技术———螺旋冲击回转钻进技术。在总结其优点的基础上提出了尚待解决的工艺难题。
Based on the construction practice and the theoretical analysis, the technique for auger-percussive-rotary drilling is defined. It is a new drilling method and is used generally in the anchor engineering of soil and rock. At last, the unresolved questions are suggested.
