非开挖定向钻技术,是20世纪80年代在世界发达国家兴起,我国90年代引进的地下管道(缆线)铺设技术。在我国东部、北部、东南部发达地区得到广泛应用。定向钻施工在非开挖技术行业中,一直是处于领先地位,定向钻进凭借不开挖路面、不阻断交通、不影响环境等优点,日渐广泛的应用于管道(管线)施工中。本文就非开挖定向钻技术在管道施工中的应用做简要阐述。 Trenchless directional drilling technology is the rise of the developed countries in the world in the 1980s and the laying of underground pipelines (cables) in the 1990s. In our eastern, northern, southeast developed area is widely used. Directional drilling has always been a leader in the trenchless technology industry. Directional drilling is increasingly used in pipeline (pipeline) construction due to its advantages of not digging the road surface, not blocking traffic and not affecting the environment. This paper briefly introduces the application of non-excavation directional drilling technology in pipeline construction.
