大口径城市供水管道的清管器除垢实验

For large caliber city descaling experiments of water supply pipeline pigging

结合大连市某输水干线维修改造工程实例,介绍了供水管道的清洗施工方案,并阐述了清管器的设计要求,通过现场试验,对该清洗方案进行了分析评价,为类似问题的研究积累了经验。

Combining with the maintenance and reconstruction projects of some water-supply artery of Dalian City,the paper introduces the cleaning construction scheme for the water-supply pipelines,illustrates the design requirements for the cleaning device,and analyzes and evaluates the cleaning scheme according to the site experiment,so as to accumulate experience for similar problems.
