摘要
基于燃气管道在城市中占据的重要地位,从前期测量放线工作入手,对沟槽开挖、管道安装(运输、防腐、下管、焊接、吹扫、强度试验、阀门井安装)及沟槽回填等施工技术的应用进行了深入分析,总结技术应用要点,为实际的管道安装施工提供参考借鉴。
Based on the important position occupied by gas pipeline in the city, starting with the work of measuring and releasing lines in the early stage, the excavation, pipe installation （transportation, anti-corrosion, down pipe, welding, purging, strength test, valve well installation） Trench backfill and other construction techniques were analyzed in-depth, summarizes the key points of technology applications for the actual construction of the pipeline to provide reference for reference.
