姜唐湖退水闸位于安徽省淮河姜唐湖蓄(行)洪区行洪下口门处。它具有挡洪、蓄洪、行洪、退洪及反向进洪的功能。本文主要对闸的过流能力、闸室上下游翼墙和闸室上下游护砌范围以及闸下消能防冲设施布置合理性进行的研究。 Jiang Tang Lake retreat gate is located in Huaihe, Anhui Province Jiang Tang Lake reservoir (line) Hong flood area under the gate. It has flood blocking, flood storage, flood, flood and reverse the flood into the function. This paper mainly studies the over-flow capacity of the sluice gate, the upstream and downstream wing walls in the sluice chamber and the upstream and downstream sanding range of the sluice chamber, as well as the rationality of the layout of the floodgates and flood absorbers.
