摘要
分析了高压盘式封堵作业从开挖封堵作业坑、氮气试压、密闭开孔、旧管线焊接盲板、管线连头作业、管沟回填作业等6个工序的风险,结合实践提出安全控制措施。
This paper analyzed high-pressure disc plugging jobs＇ 150 risks of six processes during the excavation and plugging operation pit, nilrogen pres- sure test, closed portiforium, old pipeline welding with hlankoff plate, piping head job and trench hack- fill operations. Combined practice, we put forward practical safe control measures.
