摘要
底格栏栅坝取水枢纽具有结构简单、施工及运用方便、节约投资、不改变河道形式并能有效排除大粒径推移质等优点。根据四川呷榴河三级电站底格栏栅坝取水枢纽的设计研究,总结了底格栏栅坝满足引水排沙并兼顾生态环境功能的水力设计过程,对底格栏栅进流的水力计算、取水廊道无压流的水力计算及底格栏栅坝的泄流计算进行了详细论述。对于改进和完善底格栏栅坝取水枢纽设计建设具有参考意义。
The bottom trash rack dam has the advantages of simple structure,convenient construction and operation,low investment,unchanging river course and effective removing large-size bed-load.According to the design and research on the bottom trash rack dam for water intake of Galiu Ⅲ Stage Hydropower Station in Sichuan Province,the hydraulic design process of bottom trash rack dam for meeting the requirements of water diversion and sediment removal,as well as eco-environment is summarized,the hydraulic calculations of the free flow in water intake gallery,flow discharge and inflow of bottom trash rack are introduced in detail,which provide significative reference for improving design and construction of the bottom trash rack dam.
