Research on Carbonization and Erosion Prevention of U-shaped Thin-walled Aqueduct:A Case of Cheyuan and Wuxi Aqueducts
A large number of U-shaped thin-walled aqueducts in Zhejiang Province have been in service for a long time and the aging diseases such as carbonization and cement mortar falling have appeared.In order to maintain the normal water delivery capacity of the aqueduct and ensure its safe operation,the on-site safety inspection of the aqueduct is required.The bodies of Cheyuan Aqueduct and Wuxi Aqueduct in the irrigation area of Yuankou Reservoir in Wuyi County were tested,and it was confirmed that the main diseases of the aqueducts were caused by carbonization damage and erosion.In order to address these two major diseases,the combination of basement treatment,polymer mortar repair,coating sealing protection and pasting carbon fiber belt was adopted to im-prove the strength of the aqueducts to a large extent and achieve the expected repair effect,providing reference for the repair of other aging aqueducts in the future.
