在八屋—长春输气管线佟家窝堡北穿越河道时,采用定向钻孔技术。本文阐述了冬季定向钻孔穿越超宽河道基底砂层的设计要点、施工工艺。
In the construction of passing through under of the river,northern part of Tongjiawopu,Bawu-changchun gas pipeline,we adopted directional drilling technology.The paper summarized the main point of design,directional hole drilling technology in winter in the work site.
