A rubber dam is made of high Strength and good water resistance nylon canvas and aging durable compound rubber supported by a frame and prefabricated rubber,riveted store water. Discharge the water or air in the dam tube when no need to store water. Advantages of rubber dam are shorter construction period(final construction period 3-6 months).less engineering budget and it can save 40% than that of civil works. Rubber dam on the concrete base board to form a sealed bag shaped space inflated water or air to has the features of long service life, simplified maintenance and improved vibration resistance.

The rubber dam is suitable for the projects with lower water level and large span sluice, widely used for irrigation, power  generation, flood control and urban  landscaping.
