高水位变幅拦污漂设计与安装技术研究

Research on Design and Installation Technology of Trash Rack in High Water Level and Variable Amplitude

白鹤滩水电站从初期蓄水拦污至正常蓄水位拦污,高度变幅范围达到约190m,为解决白鹤滩水电站拦污漂能够适应高水位、大变幅等工程难点,设计了一种适应此类落差较大工况下的柔性拦污漂型式,并提出了一套施工安装方案。工程实际运行证明,该方案成本优、可靠性高。

Baihetan Hydropower Station has a height variation range of about 190m from the initial impoundment to the normal impoundment level. In order to solve the engineering difficulties of trash rack in Baihetan Hydropower Station, such as adapting to high water level and large amplitude variation, a flexible trash rack type is designed to adapt to such large drop conditions, and a set of construction and installation scheme is proposed.The actual operation of the project has proved that the scheme has excellent cost and high reliability.
