钢管拱桥钢管表面防腐和防锈施工技术

On the anti-corrosive and anti-rust construction technology of the steel tubular arch bridge

针对钢管防腐、防锈对钢管混凝土拱桥的重要性,指出大气腐蚀是引起钢管混凝土拱肋表面腐蚀的主要因素,通过具体工程实例,介绍了钢管拱桥钢管表面防腐、防锈施工技术,得出了GCM金属防护对钢管混凝土拱防护效果较好的结论。

Aiming at the importance of the steel tubular anti-corrosive and anti-rust of the steel tubular of the concrete arch bridges, the paper points out the atmospheric corrosion is the main factor for the surface corrosion of the steel tubular concrete beam, introduces the anti-corrosive and anti-rust construction technology of the steel tubular arch bridge according to the factual projects, and concludes GCM metal protection has better protection effects for the steel tubular concrete arch.
