船闸是靠闸室充水和放水来调节航道水位,以实现船只通航的建筑物。由上游航道向闸室充水以及由闸室向下游放水,分别通过设于上、下闸首的输水廊道,并由廊道闸门控制。在正常设计通航水位条件下,输水过程决定于廊道门过流面积、闸门开启速度和闸室面积。输水过程,主要是输水时间和最大瞬时流量,对船闸通航效率和船只安全 The lock is to rely on the lock chamber water and water to adjust the channel water level, in order to achieve navigation of the ship’s buildings. Water is supplied to the lock chamber from the upstream channel and water is discharged from the lock chamber to the downstream, respectively, through the water supply corridors located at the upper and lower gate heads, and controlled by the gallery gates. In the normal design of navigable water level conditions, the water process depends on the corridor gate flow area, gate opening speed and gate area. Water delivery process, mainly the water delivery time and the maximum instantaneous flow rate, the ship lock navigation efficiency and vessel safety
