滨海城市智能截流井防倒灌堰门高度研究

以湛江水环境综合治理工程为例,提出滨海城市智能截流井防倒灌堰门的高度,通过观测数据进行分析。结果表明,在滨海城市的河涌边,采用智能截流井截流合流管渠时,其防倒灌堰门的高度与外河(江)潮位高度呈现正相关关系,并与外河(江)潮位高度的1.2倍有一定的差值;防倒灌堰门的高度与其井内液位的高度始终保持一定的差值。结论可对周边滨海城市建设过程中,类似的水环境综合治理项目设计智能截流井防倒灌堰门的高度控制具有重要的参考价值,也可减少智能截流防倒灌堰门的能耗。

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.
