曹娥江大闸工程处于淡水、海水多种影响环境,受潮汐干湿交替、河口水含泥沙量冲蚀等因素影响较大,对闸门防腐环境要求较为苛刻。本文通过室内、室外与闸门所处同等环境的影响试验,提出了适合闸门防腐要求条件的处理方案,收到了良好的钢闸门防腐效果,为沿海地区闸门防腐提供了参考案例。
The project of Cao’e River Sluice is affected by a variety of influences of fresh water and seawater. It is greatly affected by such factors as tidal alternation of wet and dry water, sediment erosion of estuaries and other factors, and more stringent requirements on the anti-corrosion environment of the gates. In this paper, through the experiment of the influence of the same environment inside and outside the gate with the gate, this paper puts forward the treatment scheme that meets the requirements of the gate corrosion protection. It has received a good steel gate anti-corrosion effect and provided a reference case for the gate corrosion protection in the coastal area.
