摘要
如何解决低水头径流式电站的防沙问题,防止发电进水口淤积,减少泥沙过机一直是水工建筑物检修的技术难点。本文通过对葛洲坝大江电厂排沙底孔上游检修门槽底坎区域冲坑成因的分析及处理方法的研究,希望能够对同类型水工建筑物检修提供借鉴。
How to deal with the problem of anti-sediment and decrease sediment through hydraulic turbine is always a problem. This article introduced the cause analysis and research on the way to deal with scour hole in the area of sediment flushing bottom outlet in upside check gate of Gezhouba Dajiang hydropower factory, hopefully it would be useful to similar maintenance.
