长距离输水管线静水压力试验参数设计要点

Key points of parameter design for hydrostatic pressure test of long water delivery pipeline

结合目前国内施工实践经验,对PCCP长距离输水管线静水压力试验参数设计要点进行了总结探讨,重点论述了试验段选定、堵头和后背设计要点,以及试验设施选定、安装设计方法。

Combined with current domestic construction practice, the author summarized the key points ot parame- ter design for hydrostatic pressure test of long water delivery PCCP pipeline, with emphasis put on selection of test- ing section, design of pipe-end plug and backup, determination and assembly of testing facilities.
