摘　　要：管道沟槽回填作为市政排水工程设计及施工的重要组成,其安装质量不仅影响管道寿命,还影响市政道路路基路面质量,但现行给排水专业的施工验收规范对实际操作缺乏指导性,且不符合道路专业最新规范要求。论文研究了刚性管道和柔性管道在不同埋深情况下规范对管道沟槽回填做法的具体要求,分析了给排水和道路专业规范要求存在差别的原因,并提出了针对不同情况的具体做法。As an important component of municipal drainage engineering design and construction,pipeline trench backfilling not only affects the service life of pipelines,but also affects the quality of municipal road subgrade and pavement.However,the existing construction acceptance standards in the water supply and drainage profession lack guidance for practical operation and do not meet the latest requirements of road professional standards.The paper studied the specific requirements for pipeline trench backfilling practices in different burial depths for rigid and flexible pipelines,analyzed the specific reasons for the differences in professional specifications for water supply and drainage and roads,and proposed specific practices for different situations.
