Abstract:
The bridge erect machine (WJQ120t-30mA3) is selected to install the arc sluice gate of surface outlet of the overflow dam of Guanyinyan Hydropower Station according to the practical field condition, the particularity of the arc sluice position, the installation position of hydraulic cylinder of the hoist and oil-pipe beam, and the lifting requirement. The bridge erect machine can lift the sluice in a safe, quick and reliable way through reasonable layout. The machine innovate d the installation technique, reduced the difficulty of lifting, ensured the installation quality and shortened the period, so the impoundment goal of Guanyinyan Hydropower Station was achieved.
Key words: arc sluice, overflow surface outlet, bridge erect machine, installation technique, Guanyinyan Hydropower Station
