| 中文摘要:与常规的槽探和回转钻进相比，利用冲击钻探方法进行地质土壤取样具有取心效率高、取样质量高、对环境破坏小等优点。 为此研制了一种轻便型的冲击取样钻机。通过对冲击原理分析，钻具设计以及拔管器结构分析计算，经过多次设计验证，并在2次现场试用的基础上，进行了不断改进。实践证明该钻机取样效率高，土壤原状保持程度好，能满足高质量土壤取样施工的技术要求。 |

| Abstract:Comparing with conventional trenching exploration and rotary drilling, geological soil sampling by percussion drilling has the advantage of high core recovery, high sampling quality and less damage to the environment. A portable percussion drill rig was designed with continuous improvements made through the analysis of the impact principle, the design of the drilling tool and the analysis and calculation of the structure of the pipe puller multiple design verifications, and twice field trials. Practice has proved that the percussion sampling drill rig can work with high efficiency with hi-fi soil samples, which can meet the technical requirements of high-quality soil sampling works. |
