摘要
预应力钢筒混凝土管(PCCP)是当前国内供水工程推广的新技术。因长期埋设在土壤中,PCCP管中的钢构件不可避免会发生腐蚀,其最佳防蚀的方法是阴极保护。本文结合国内外的实践经验,介绍了南水北调工程北京段PCCP管实施阴极保护的情况,以期为国内其它PCCP管的建设应用提供借鉴。
Prestressed concrete cylinder pipe （PCCP） is a new technology for water supply project. To avoid the corrosion of steel structures （steel cylinder and pre-stressing wire） embedded in soil, cathodic protection （CP） technology should be the best method. Based on the practical experience at home and abroad, the design and test results of cathodic protection for PCCP in south-to-north water transfer engineering are introduced.
