石家庄输气管道穿越南水北调总干渠安全影响评估

Assessment of the Security Implications of Shijiazhuang Gas Transmission Pipeline Crossing South-North Water Transfer Main Channel

定向钻是一项专用于修建油气管道穿越工程的新技术。在石家庄输气管道穿越南水北调中线总干渠时拟采用此法施工。结合工程经验和相关理论分析,通过对管道布置、施工方法、以及总干渠衬砌结构特点的分析,对管道穿越工程的安全影响提出了合理可行的评估意见,为专家审查提供参考。

Directional drilling is a new traversing engineering technoogy used for constructing oil gas pipeline,which is introduced in the Shijiazhuang gas transmission pipeline crossing South-North Water Transfer main channel.Combining with the experiences of engineering and making theoretical analysis,reasonable assessment opinions of the security implications of pipeline traversing engineering are proposed to provide reference for assessment of the professionals,which is based on the analyses of piping layout,construction methods and construction features of main channel lining.
