泥沙淤积是中小河口建闸后需要解决的问题,它将影响到工程效益的充分发挥,甚至威胁到泵闸本身设备的安全运行。本文结合浦东国际机场江镇河出海泵闸多年运行管理经验,对该闸闸下淤积从自然原因、工程原因、外界原因等方面进行分析,回顾论述该闸所采取的水力冲淤、机械清淤等措施及效果,最后又从工程措施、植物措施及运行措施等方面对其淤积防范提出探讨和初步设想。
Sedimentation is a problem that needs to be solved after the sluice is established in small and medium estuaries. It will affect the full realization of engineering benefits and may even threaten the safe operation of the pump itself. Based on the years of operation and management experience of Jiangzhenhe seawater pumping station at Pudong International Airport, this paper analyzes the siltation under the sluice gate from the aspects of natural cause, project reason and external cause, and reviews the hydraulic scouring and silting, mechanical dredging And other measures and results, and finally from the engineering measures, plant measures and operational measures to prevent and prevent siltation of its initial tentative plan.
