桃源水电站锚链悬索拦污排研究

Research on Anchor Chain Cable-suspended Trash Barrier

在总结以往拦污排研究成果和工程经验的基础上,归纳了拦污排设计的主要因素,对悬索拦污排主索荷载假定与结构进行分析。在桃源水电站锚链悬索拦污排设计中,采用线型低密度聚乙烯浮箱、锚链悬索、独立网栅,具有独特的超载保护、移动清污、防事故连锁反应等功能,取得了良好的拦污效果。

By summarizing existing research results and engineering practices of trash barriers in hydropower projects, the main factors which influence the design of trash barrier are studied, and the hypotheses on main cable loads and the structure of flexible cable-suspended trash barrier are analyzed. Tile linear low density polyethylene pontoons, arch chain suspended cable and independent wire grid are used in the design of anchor chain cable-suspended trash barrier of Taoyuan Hydropower Station, and the trash barrier has functions of unique overload protection, mobile cleaning and chain accident prevention. The actual operation of anchor chain cable--susoended trash barrier has achieved good effect on trash blocking.
