大型河流定向钻穿越特殊碎石土层施工设计研究

Construction Design and Research of Directional Drilling Through Special Gravel Soil in Large River

就大型河流定向钻穿越的施工作业而言,长输管道工程十分关键,可有效保证管线顺利的穿越。结合淠河管道工程,对穿越处的地形勘察设计、施工管道设计展开详细探讨,并针对穿越施工过程中面临的问题提出相应的解决措施,最终取得了良好的施工效果。

As far as the construction ation of directional drilling across large rivers is concerned,long-distance pipeline engineering is very important,which can effectively ensure the smooth crossing of pipelines.Based on the Pi river pipeline project,this paper discusses in detail the topographic survey and design of the crossing and the design of the construction pipeline,and puts forward corresponding measures to solve the problems in the crossing construction,and finally obtains good construction results.
