2.2 船闸运行方式
船闸运行方式是指按上行过闸和下行过闸的过程进行船舶过闸运行,二个过闸过程交替进行,上行过闸完毕即进入下行过闸准备,下行过闸完毕即进入上行过闸准备。
1、 上行过闸:
上行过闸是指船舶从下游到上游的过闸过程。上行过闸时,下闸门已经打开,闸室水位与下游水位齐平,船舶可以从下游驶入闸室停泊。当全部上行船舶进闸完毕,关下闸门,下闸门关终后,打开上阀门,上游向闸室灌水(在反向水头时,闸室向上游引航道泄水),当闸室水位与上游齐平时,打开上闸门,船舶出闸驶入上游。
2、 下行过闸:
下行过闸是指船舶从上游到下游的过闸过程。下行过闸时,上闸门已经打开,闸室水位与上游水位齐平,船舶可以从上游驶入闸室停泊。当全部下行船舶进闸完毕,关上闸门,上闸门关终后,打开下阀门,闸室向下游泄水(在反向水头时,下游引航道向闸室灌水),当闸室水位与下游齐平时,打开下闸门,船舶出闸驶入下游。
