开挖斜(竖)井在陡坡处敷设长输管道的施工方法

Method of Lay Down Pipeline with Drilling Inclined/Vertical Well at the Steep Location

在国家重点建设项目义马至郑州输气管道工程建设中 ,首创了在陡坡陡坎处开挖斜(竖 )井敷设管道的施工方法。采用该方法可降低工程造价、节省管道的维修费用 ,同时可保持施工现场原有的地形地貌 ,防止水土流失 。

During the construction project of Yima-Zhengzhou gas pipeline,the method of lay down pipeline with drilling inclined/vertical well at the steep location was used in the first time.It can reduce the costs,save pipeline maitenance expanses and keep the landform & topography,protect soil erosion in the construction site with the method.
