【Abstract】 The sluice gate grooves are damaged and deformed due to long-term frequent operation,and the problem is analyzed in order to ensure the safe and controlled operation of the gate and prolong the service life of the project as far as possible. The construction mode of U-shaped double-steel cofferdam is adopted to complete the repair of the underwater part of the hydraulic structures. Main repair flow and procedures of the groove underwater part,and main performance indicators of the construction facilities are introduced in details. Suggestions are proposed for design manufacturing and operation mode in order to improve the sluice gate grooves finally. The construction method can be applied for shortening the construction period with significant economic and social effect according to practice and test,and it can be used as reference in similar projects.更多还原
