滨海城市智能截流井防倒灌堰门高度研究OA

Taking the comprehensive treatment project of water environment in Zhanjiang as an example,the height of anti-backflow weir gate of intelligent closure well in coastal city is put forward and analyzed by observation data.The results show that in coastal cities,when using intelligent interception wells to intercept and merge pipes and channels,the height of the anti backflow barrier is positively correlated with the tide level of the outer river(river),and there is a certain difference between it and 1.2 times of the tidal level of the outer river(river).There is always a certain difference between the height of the anti-backfilling weir door and the height of the liquid level in the well.Conclusion It has important reference value for designing the height control of the weir gate of the intelligent interceptor well to prevent backfilling in similar water environment comprehensive treatment projects during the construction of the surrounding coastal cities,and can also reduce the energy consumption of the intelligent interceptor well to prevent backfilling weir gate.
