Rubber dam is a new type of hydraulic structure compared with steel sluice gate, which is made of high-strength synthetic fabrics and compound rubber, anchored in the concrete foundation to form a sealed air bag inflated with air or water in dry seasons to store water. In rainy seasons, air or water inside of rubber bag would be discharged to help release floodwater from river course.
Compared with common civil works, the advantages of rubber dam are cheap engineering budget, shorter construction time, longer service life, simplified maintenance and improved vibration resistance. Rubber dam can be adjusted at any height and overflowed so it is widely used for irrigation, power generation, flood control and urban landscaping in many areas.
