The water slope ship lift design brief introduce of the Zuojiang multi-purpose dam project

The water slope of the Zuojiang multi-purpose dam project was composed of upstream adjacent naviga- tion channel, upslope top, slope channel, slope toe and downstream adjacent navigation channel, it is long 1235m. The slope channel used reinforcement concrete U style structure, propulsion machinery used the outer power, mechanical transmission, the design weight gravity was 900kN, the driving power was 648kW, its cost was 2/3 of shipping lock, water consuming was 1/34 of shipping lock, the pass-dam time was 7.7/10 of ship- ping lock, the maximum navigation ship was 120t and the design volume of goods transported was 5 hundred thousand ton in a year.
