Dahuofang Reservoir Water Diversion Project belongs to a typical long-distance pipeline project.A large amount of PCCP pipelines are adopted in the project,therefore cathode anticorrosion of pipeline is the key of protecting safe and stable operation of water diversion pipeline in the construction, operation and maintenance process. In the paper, Dahuofang Water Diversion Stage II Project is adopted as an example for briefly introducing pipeline cathode protection principle,main construction measures and its actual operation condition in project.
