Jiangya Water Control Project metal structures include dam flood discharge gates, water diversion pressure pipe, power station and irrigation works and the navigation structure of the metal structure of five major parts. In November 1996, the unit for the manufacture and installation of metal structures (contractor) was identified through bidding. In September 1998, the installation of the Zhongkeng Arc Gate and the opening and closing machinery was completed. At the end of December 1998, the metal structure of the water diversion and power generation system and the opening and closing machinery were installed , And passed the inspection. In November 1999, the dam metal structure was completely installed and passed the test run acceptance. The safety, quality and investment of the metal structure have been effectively controlled, and the contract management work is proceeding smoothly. All kinds of gates and opening and closing machinery of the metal structure project are in normal operation and have been put into operation to meet the flood control and power generation requirements of the dam
