摘要
结合工程实例,分析了非开挖水平定向钻进铺管施工中经常产生的卡管、摆管不顺等事故的原因,并提出了在扩孔头与拉管头之间加上铁罩、选择最优泥浆压力等解决方法,实践证明效果良好。
No dig horizontal directional drilling technology is more and more used in communication engineering. The accident usually occurring in construction includes： pipe locked ,the pipe can＇t pulled easily and so on. The paper analysis the reasons and give some suggestion such as adding an iron cover between the extend hole and haul pipe, choose optimization slop pressure.
