| 摘 要： | 导／定向钻进是一种技术密集型、对环境无害的地下管线铺设技术。通过综合经济比较分析，说明了导／定向钻进技术在管径大、埋深大的条件下所具有的明显经济优势。通过对国内外现有技术水平的比较，分析了我国在该技术发展规模、工程应用领域、新型高技术含量、钻机的工作性能等方面存在较大的差距。认为我国应在钻机的机电液一体化、施工过程自动化控制、配套泵组及泥浆系统、钻进规划软件开发等方面作进一步深入研究。

| Abstract: | The technique of underground pipeline laying with guided/directional drilling is technologically intensive and eco-friendly. Obvious economic advantage of trenchless construction technique of big diameter and great depth is proposed in the comprehensive economic comparison. Comparing the technological level home and abroad, the development in the aspects of developing scale, application field, the content of high technology and drill performance is much needed to improve. It is suggested to do further research in electromechanical liquid u nification of drill, automation control in construction, accessory pumps and mud system, and the development of drill program software, in order to satisfy the requirement of the economic construction development of our coun try. |
