　　This project involves the construction of a water transmission line from Deze Reservoir to a pumping station. Our company is responsible for the fabrication and installation of 2000 tons of pressure steel pipes at the dam, as well as the installation of gates, trash racks, hydraulic trash cleaners, intake well sluice gates, a 70-ton, 2.8-meter diameter conical valve, and mobile hoists. The pressure pipeline is mainly located in the lower section of the generator tunnel. The main diameter of the steel pipe is D=4 meters. The excavation inside the tunnel is irregular and narrow, making construction very difficult. Therefore, a track flatcar top-lifting installation process was adopted. The sluice gate is large, weighing 75 tons, and its installation location is 120 meters above the ground, with a narrow space, making the hoisting very difficult.
