PCCP阴极保护技术在辽西北供水工程中的应用

摘要

During the construction of the Liaoning Northwest of water supply project, in order to reduce the external medium of prestressed steel wire and steel cylinder of PCCP pipeline electrochemical corrosion damage, the sacrificial anode protection technology of cathodic protection method is applied to the construction of the PCCP Project. The project adopts protection measures of zinc anode of PCCP pipeline. The criteria, scheme, inspection of the cathodic protection method and the relevant attentions during the construction concerned are introduced herein in order to provide reference for popularize the cathodic protection technology for the construction of PCCP pipeline.%在辽西北供水工程施工中，为了减轻外部介质对PCCP管道中预应力钢丝和钢筒的电化学腐蚀破坏，采用了牺牲阳极法阴极保护技术，本工程对PCCP管线采用锌阳极保护措施；文章结合PCCP管道自身结构特点，介绍了本工程阴极保护技术所采用的保护准则、保护方案、施工方法及检测技术等，为PCCP管道阴极保护技术的推广应用提供借鉴与参考。
