1 前言 多年来,在水闸工程中,闸板止水大多采用橡皮止水,虽然止水效果比较好,但由于橡皮易老化,施工难度也大,加之管理不健全,止水橡皮被切割被破坏的现象相当严重。因此,止水效果得不到保障,使用寿命也短。针对橡皮止水存在的问题,笔者曾于1989年提出了闸门钢止水原理和制安方法。根据几年来工程应用和实践验证,钢止水对中小型水闸确实适用,不足之处
1 Foreword Over the years, in the sluice project, most of the sluice gates adopt the rubber water stop, although the water stop effect is better, but the rubber is easy to age, the construction is also difficult, combined with the management is not perfect, the water stop rubber is cut and damaged The phenomenon is quite serious. Therefore, the effect of water stop can not be guaranteed, the service life is also short. In view of the existing problems of rubber water stop, the author once proposed the principle of water stop of steel gate and the method of making safety in 1989. According to several years of engineering applications and practical verification, steel stopwatch really applicable to small and medium-sized sluice, inadequacies
