Research on Corrosion and Defects of Hydraulic Metal Structures

摘要

Abstract The environmental conditions of hydraulic metal structures are complex. Analysis of the causes of corrosion and defects of hydraulic metal structures shows that the causes of corrosion and defects of metal structures mainly include corrosion, cavitation and erosion and erosion wear. According to the specific causes, the schemes and measures to prevent the corrosion and defects of metal structures are introduced; the existing methods for repairing underwater metal structures including blocking gate method, side caisson cofferdam method and steel cofferdam method are introduced; meanwhile, the methods of. The feasibility of deep-water metal structure underwater robot repair technology.
