Metal Structure Design of Yunzhou Reservoir Danger Removal and Consolidation Works

云州水库除险加固工程金属结构部分根据闸门和启闭机目前存在的问题进行了改建设计。对泄洪洞进口事故闸门卷扬启闭机和发电输水洞进口事故闸门卷扬启闭机进行了更新,启闭机容量和扬程均较大。该文对金属结构改建设计进行了介绍,对高扬程卷扬启闭机设计的关键部位卷筒和挡环进行了重点介绍。

According to the problem of gate and hoist at present,the metal structure design of Yunzhou reservoir danger removal and consolidation has made reconstruction designs.The inlet emergency gate winch-hoist of flood discharge tunnel and power water hole has been updated,and the capacity and lift of the hoist are both large.This paper has introduced the metal structure reconstruction design,and the key positions-drum and dam ring of high-lift winch-hoist are especially introduced as emphasis.
