摘要
本文报道在淡水环境中采用铝合金和镁合金复合式牺牲阳极对钢管桩进行阴极保护的可行性研究。分别检测了安装3组、4组或5组复合牺牲阳极后,钢管桩1天和7天的极化电位,评估了该方案的实际保护效果,确定了较为合理的镁合金与铝合金牺牲阳极的用量和比例。
It was a feasibility study of cathodic protection for steel pipe pile in fresh water, in which combined type sacrificial anodes of Al alloy and Mg alloy were used. When equipped with 3 groups, 4 groups or 5 groups combined type sacrificial anodes, tested the polarized potential on the 1st day and the 7th day, evaluated the actual protection results, and also defined the reasonable quantity and ration of the Al alloy anode and Mg alloy anode in the combination.
