摘要
港珠澳大桥主体工程钢箱梁结构在亚热带海洋性气候条件下防腐施工难度极大,其防腐涂装施工费用创下了中国桥梁之最。通过对港珠澳大桥钢结构工程腐蚀环境特点及工程涂装技术的要点进行分析,对HSE体系下港珠澳大桥在海洋环境下钢结构防腐涂装的一些涂装厂房、喷砂技术、新型磨料技术、喷涂技术等关键技术进行了探究,对跨海大桥钢结构防腐技术的发展有着重大的实践和推广意义。
The steel box girder structure of the main body of the Hong Kong-Zhuhai-Macao Bridge is extremely difficult to carry out anti-corrosive work under subtropical oceanic climate,and its anti-corrosive coating construction cost reaches the highest in China.Through analysis of the corrosive environment characteristics of the steel structure engineering of the Hong Kong-Zhuhai-Macao Bridge and the main points of engineering coating technology,some crucial techniques such as coating plants,sandblasting technologies and new types of abrasive technique,spraying technique for the steel structure anti-corrosive coating of the Hong Kong-Zhuhai-Macao Bridge in marine environment are explored within the HSE system,which has great practical and promotional significance for the development of anti-corrosive techniques for steel structures of cross-sea bridges.
