Construction Technology of Anti-Corrosion Coating for Steel Bridge Deck Pavement of Nansha Bridge
In order to guide the construction of anti-corrosion coating on steel bridge deck,the key technical control indexes of sand blasting and epoxy zinc rich paint construction are determined through the research on the construction technology of steel bridge deck sand blasting and epoxy zinc rich paint.The research shows that when the shot blasting machine adopts the shot sand ratio of 2∶1,the walking speed shall not be greater than 3.0 m/min;When spraying epoxy zinc rich paint with spray gun,the uniformity of film thick-ness is better than manual roll coating,and the qualified rate is relatively high;Spray gun spraying and manual roll coating of epoxy zinc rich paint have little effect on its drawing strength.Through the research on the construction technology of anti-corrosion coating,the rationality of the key technology of anti-corrosion coating construction is verified.
