- Abstract
Yingpan lock is the highest single level lock at present in China with a working head of 36.5m.This paper presents a regulation tank lock scheme and the water saving lock scheme to settle the valve hydraulics problem caused by high water head.By analyzing and comparing of the general single level lock,the regulation tank lock and the water saving lock,it is concluded that not only the recommended water saving lock can satisfy the design and the correlated operation requirements,reduce the valve work head by a half to simplify value hydraulics problem,but the water saving is possible at least by 48.6% in one ship passage through the lock.
