关于PCCP管道安装中出现接头漏水问题的探讨

Exploration on joint leakage occurring in PCCP pipeline installation

针对在PCCP管道安装过程中,管道接头试验出现压力不满足要求及打压出现漏水现象的成因(PCCP管道椭圆度、安装间隙、地基变化、止水胶圈、地下水位变化等)进行了分析,并对处理的一些方法进行了探讨,以保证管道安全运行。

This paper analyzes causes of insufficient pressure and leakage occurring in pipeline joint test of PCCP pipeline installation（PCCP pipeline ellipticity,installation interval,foundation transformation,waterproofing rubber ring,groundwater table transformation and so on）,and explores some treatment methods,with a view to guarantee safe pipeline operation.
