外加电流阴极保护技术在港口工程中的应用

Application of Impressed Electric Current Cathodic Protection to Port Engineering

码头设施的腐蚀状况关系到结构安全和耐久性能。天津港北港池集装箱码头采用计算机远程控制外加电流阴极防腐技术,保护钢管桩和钢筋混凝土结构获得成功。根据工程实例,介绍外加电流阴极保护技术的施工工艺、施工质量控制要点、效果评价,可供港口建设防腐工程参考。

The corrosion state of wharf facilities is related with the safety and durability of the structure. The cathodic protection anti-corrosion technique which combines computer remote control with impressed electric current are applied for the container terminal of North Basin, Tianjin Port. It is succeeded in protection for steel pipe pile and reinforced concrete. The construction technology of impressed electric current protection skill, the key points for controlling construction quality and effec evaluation are introduced. Which can be taken as the reference for the corrosion prevention project of port construction.
