近年来,在江苏省平原地区的河道上及沿海一带,修建了许多涵洞、水闸和船闸。其中涵洞都是采用直升式平面闸门,水闸采用弧形闸门和直升式平面闸门两种,船闸则大多采用人字式闸门和横拉式闸门。这些闸门的止水设备都是采用木止水或橡皮止水。从实际运用的情况看来,由于止水效果不好,闸门漏水已成为相当普遍的现象。作者最近收集了一些资料,提出关于闸门止水设备上存在的问题,同大家商讨。
In recent years, many culverts, sluices and locks have been constructed along the rivers and along the coast of the plain in Jiangsu Province. Among them, the culverts all adopt the helicopter type flat gate, the sluice uses the arc gate and the helicopter type flat gate, and the lock gates mostly adopt the gable gate and the horizontal pull gate. The water stop equipment of these gates adopts wood water stop or rubber water stop. It seems from the actual situation of the case, due to poor water stop, gate leakage has become quite common phenomenon. The author recently collected some information on the water gate equipment on the existing problems, to discuss with everyone.
