水电站进水口浮式拦污排的应用与设计刍议

Discussion on Application and Design of Floating Trashrack for Power Intake

目前,我国浮式排污排的设计没有相应的设计规程或规范可循。介绍浮式拦污排在水电站进水口前沿的应用情况,针对现有拦污排拦污效果不是十分理想的现状,提出对水电站进水口前沿漂浮物应采用拦、导、清、排的综合处理措施,并介绍了现有浮式拦污排的几种形式,设计中应注意的问题,以及计算方法等。

There are no codes and standards for design of floating trashrack in China so far. The paper makes an introduction to the application of floating trashrack for power intake and proposes a comprehensive treatment measure, which includes blocking, guiding, clearing and draining, for dealing with the floating matters in front of intake because of poor effect of existing trashrack. Moreover, the paper gives a description on modes, design attentions and calculation methods etc. of existing floating trashracks.
