冯家山水库除险加固中弧形钢闸门安装的技术要点

Installation Techniques of Radial Steel Gate in the Reinforcement of Fengjiashan Reservoir

笔者在总结分析了冯家山水库枢纽输水洞、泄洪洞出口弧形工作闸门启闭机改造原由的基础上,重点对液压启闭机在水库除险加固中所采用的吊装方案、拼装工艺,安装技术、质量控制及实际应用效果进行了阐述,比较有特色,值得类似水库借鉴参考。

Based on the summarization of alteration cause of radial steel gate of water delivery tunnel and the exit of flood discharging tunnel in Fengjiashan reservoir,this paper elaborates the lifting scheme,assembling technique,installation technique,quality control and application effect of hydraulic hoist in reservoir reinforcement,which can be used as reference for similar reservoir.
