摘要
结合燃气管道非开挖定向钻穿越快速公路的工程实例,分析了定向钻技术决定工程成败的技术关键点,总结了穿越工程中轨迹设计、泥浆配置、管线探测、管材连接、导向钻进、扩孔护壁、回拖等方面的实践经验。
Based on the engineer instance of gas pipeline trenchless installation directional drilling across the the highway project, analyzes the technical decisions of directional drilling technology key to success or failure of the project, summed up in the path through the project design, mud configuration, pipeline detection, pipe connection, oriented drilling, reaming, dragged back to the areas of practical experience.
