Investigation and Treatment of Floating Debris in Xinglong Hydro-junction on Hanjiang River
Xinglong Hydro-junction Project is located in the lower reaches of the Hanjiang River,with flat terrain and broad river section at the dam site.The floating debris on the river are diverse and complex.Inappropriate handling of these floating debris will block the normal inflow of hydropower station and cause power generation head loss,reduce the operation efficiency of the project,and easily lead to water pollution in the middle and lower reaches of the Hanjiang River.We investigated the causes,characteristics and transport rules of floating debris in Xinglong Reservoir area.Following the treatment idea of"blocking,guiding,and cleaning",we conducted floating debris treatment experiment based on hydraulic and river engineering model.Comprehensive treatment measures such as float blocking,trash rack and trash-cleaning machinery were applied in practice,and favorable effects were obtained.
