Detailed design and construction consultation of Xinong River barrage

Client : Water Resources Bureau of the Southern District, Water Resources Administration, Ministry of Economic Affairs
Planned location : The middle reaches of Xinong River, Taoyuan Township, Kaohsiung County
Programme Duration : 
    Construction started in November 97 of the Republic of China ~ (Suspension after the Morakot typhoon)
Program Overview : 
    The weir design of the barrage is low, the weir type adopts a three-stage drop type, each stage drops 2 meters, and the weir surface design focuses on the wear and tear caused by the rolling of the riverbed material, and the wear-resistant concrete (strength 630 kg/cm2) is used in this plan. The total width of the fixed weir is 200 meters, from the left bank to the right bank, respectively: 74 meters for the left bank water intake section, 8 meters for the fish passage, 1 meter partition wall at each end of the fish passage, and 116 meters for the right bank water intake section. The water intake method adopts the pipe grid to take water (rear water intake), the design of the pipe grid angle, gap width and other pipe grid types and arrangements are calculated by hydraulic theory, and the hydraulic model test is handled by the water conservancy planning laboratory, and the design analysis is fed back by the model test data, and the barrage will be the largest pipe grid water intake project in China after completion.
