PCCP管道的水压试验技术分析

给水管道水压试验是对给水管道施工质量的综合性检验,也是管道工程施工的一个重要工序。当PCCP管路安装技术检查资料完整且逐个接口水压试验已合格后,是否进行全线或分段水压试验,我国尚无标准。在内蒙古呼市的引黄一、二期工程、宁夏宁东引水工程中,管材均为PCCP管,管径为DN2200～DN600,业主首次使用PCCP管材,也无PCCP管道水压试验的技术数据,因此要求施工方对管线进行抽检。现将抽检段管道水压试验进行总结,对试验结果进行分析,以便为今后的施工积累经验。

Water supply pipeline pressure test is a comprehensive test to the construction quality of water supply pipeline, and is also a major process of pipeline construction. When the PCCP pipe installation techniques Checking data is integrity and all interface pressure tests have been qualified, Our country has no standard on whether to do full or sub-hydrostatic test. The pipes using in the one and two projects of Yellow River diversion to Inner Mongolia-Hohhot,Ningxia Ning Dong diversion works are PCCP pipe diameter DN2200-DN600, the first use of PCCP pipe for owners, they had no PCCP pipe pressure test technical data, thus required the construction side to sample the pipeline. Now this paper is to Summarize sampling section of the pipeline pressure ,and analyz the test rcsuhs in order to gain experience for future construction.
