Inflatable 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.
The rubber sheet for the dam tube is made by calendaring and
vulcanizing canvas and rubber material. The canvas serves as the
force-bearing frame of the dam, and is made of chinlon *6 with high
strength, good flexural stress resistance and excellent adhesion
function. The rubber connects and projects the canvas layers, and
is distributed in outer-layer, middle-layer and inner-layer.
