Rubber dam is made of high-strength synthetic fabrics and compound rubber, anchored in the concrete foundation to form a sealed air bladder inflated with water or air in dry seasons to store water. In rainy seasons, water or air inside of rubber bladder would be discharged to help release floodwater from river course. Compared with common civil works, the advantages of rubber dam are less engineering budget, shorter construction period, extended 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.
GR makes high quality andperformance Rubber dam because of the professional production technology andadvanced machines. Rubber dam serves the irrigation projects and city planningall of the world.
The rubber bladder is made of strength canvas and rubber layers. The canvas serves as the force-bearing frame of the dam with good flexural stress resistance and excellent adhesion function. The rubber layers consist of out-layer, middle-layer and inner-layer to protect the canvas.
Physical and mechanical properties of the rubber material for making rubber bladder.
1.Easy installation, less maintenance and long life.
3.The fin structure reduces oscillation when water over flowing.
4.Good effect on collapsing, resistance to debris.
