Rubber dam, also known as rubber sluice, is a bag type retaining dam formed by using
high-strength synthetic fiber fabric as the stress skeleton, coating rubber inside and outside as the protective layer, processing it into adhesive tape, anchoring it on the bottom plate into a closed dam bag, and expanding it with water (gas) through the filling and discharging pipeline. The dam crest can overflow, and the dam height can be adjusted as required to control the upstream water level, so as to give full play to the benefits of irrigation, power generation, shipping, flood control, tide retaining and so on.
