rubber dam

Rubber dam is a permanent rubber bladder anchored in concrete foundation by anchor plates and anchor bolts. It is made of high strength fabric and synthetic rubber. The rubber dam filled with water or air could raise the water level in dry season and release floodwater from river course in rainy season. A layer of stainless steel mesh or ceramic chips can be embedded in the top surface rubber layer to reduce or prevent vandal damage. Compared with common conventional dam, the rubber dam has many advantages including less engineering budget, shorter construction period, longer service life, simpler maintenance and better vibration resistance. Rubber dam can be adjusted at any height and overflowed so it is widely used for irrigation, hydro power generation, flood control, environment improvement and recreation purpose in many areas.
