龙江水电站表孔弧门焊接工艺优化及L型水封补偿技术应用

Process Optimization of Redial Gate Welding and Application of L-shape Water Seal Compensation Technique of Longjiang Hydroelectric Station

云南龙江水电站大坝表孔弧门因特定时期需发挥防洪、泄洪作用,且整个项目节点工期需提前,在弧门安装中不断优化焊接工艺,应用L型水封补偿技术,保证了弧门蓄水、止水质量,也达到了项目提前投产的目的。

In specific periods, the redial gate plays an important role in both flood control and flood discharge of Longjiang Hydroelectric station in Yunnan Province. To complete the whole project earlier, the welding process should be optimized. By using L-shape water seal compensation technique, water impoundment and water sealing can be guaranteed, and the project can be put into operation in advance.
