文章通过许昌市南水北调配套工程泵站金属结构制作安装的实践,总结金属结构喷射除锈及涂装质量控制的几个要点,保证南水北调配套工程泵站的安全、可靠和经济运行。通过对上述各工序的严格控制,该泵站的金属结构工程包括钢管内外防腐及拦污栅和埋件的防腐除锈均达到了设计和相关规范要求,一次合格率达到97%以上,优良率达95%以上。
This paper summarizes the key points of jetting rust removal and coating quality control of metal structures through the practice of manufacturing and installing the metal structure of pumping stations in the supporting project of South to North Water Diversion Project in Xuchang City so as to ensure the safety, reliability and economic operation of pumping station of South - to - North Water Diversion Project. Through rigorous control of the above processes, the corrosion resistance and rust removal of the metal structure engineering of the pumping station, including steel pipe inside and outside the anti-corrosion and trash rack and embedded parts have reached the design and related specifications, a pass rate of 97% or more, good rate Up to 95%.
