In response to the deterioration of reinforced concrete caused by long-term operation in harsh environments in a large number of whaves built in the twentieth century,relying on the reinforcement and repair project of Ningbo-Zhoushan Port phase II wharf,we design different basalt fiber products to use for targeted reinforcement and repair,which include using double-layer basalt fiber cloth (300 g/m2 to 380 g/m2) combined with adhesive to reinforce the panel,implanting basalt fiber reinforcement combined with steel sleeve support formwork to inject C40 underwater non-dispersed concrete for increased cross-section method,and adding basalt fiber mesh combined with concrete for surface layer crack control reinforcement.Combining with the construction process,we achieve the comprehensive application of basalt fiber cloth,reinforcement,and mesh in the old wharf,and evaluate the application effect of about 2 years after construction.The results show that there is no bulging or peeling phenomenon in the basalt fiber cloth,and there are no harmful cracks in the basalt fiber mesh and reinforcement composite concrete structure.The overall appearance quality is well.
