丰满水电站泄洪洞事故闸门改造的优化设计

Optimized Design of the Emergency Gate Transform for Flood Discharging Tunnel in Fengman Hydropower Station

丰满水电站泄洪洞增建发电支洞后,原闸门的功用发生较大变化,其上部的配重箱占位、充水阀操作方式等存在不足,已很不适应检修、维护、操作需要。通过对闸门实施改造优化设计,在不改变水工结构前提下较好地消除了技术缺陷,保证了闸门可靠运行和检修需要。

After building branch tunnel in Fengman hydropower station, the function of the old gate changes greatly. Shortcomings ex- ists in the upper loaded vans available in sites and the water filling valve, making it difficult for repairing, maintenance and operation. Through the implementation of the optimization on the gate, technical defects are eliminate, not changing the hydraulic structure, thus ensuring reliable operation and maintenanee needs.
