静水压试验是对压力输水管道工程中的管道、接头、管件、阀件及镇墩、连通、分水口等附属建筑物的综合验证。在南水北调中线北京段PCCP管道工程施工中,采用全线充水、分段打压的方法对管道各个部件进行了静水压力试验,从而对管道的设计、施工及安装质量进行检验,为管道工程长距离、大口径PCCP管道提供了参考经验。
Hydrostatic pressure test is a comprehensive verification of the pipelines, fittings, fittings, valves and town piers, communication, water diversion and other ancillary buildings in the pressure water pipeline project. During the construction of PCCP pipeline project in Beijing section of midline of South-to-North Water Diversion Project, hydrostatic pressure test was carried out for all components of the pipeline by means of filling with water and segmented pressure across the pipeline to test the design, construction and installation quality of the pipeline, Large-caliber PCCP pipe provides a reference experience.
