Air Inflatable Rubber Dam

Air inflatable rubber dam, a long tubular-shaped fabric, is a novel hydraulic building presented by the development of macromolecular synthetic material industry. It consists of high strength canvas as the reinforced framework and synthetic rubber, is fixed to a reinforced concrete foundation using clamping plates and anchor bolts.
~ In dry seasons, the rubber dam is inflated
by air to retain water for industrial, agricultural and living water demands; in rainy seasons, the air in the sealed bag can be deflated out to release floodwater from river course. Its cost is lower than water inflatable
rubber dam and traditional dam. It can be installed in 3
to 15 days and be put into use soon. Medium will not freeze in winter. It is usually used for retain water, irrigation, control flood, power generation, etc.
Material structure: one cloth two rubber, two clothes
three rubber, three clothes four rubber, etc.
Color: blue, black, red, gray, purple, etc.
Medium in dam: air.
According to installation method:
Double anchor (pillow-like dam and inclined dam).
According to anchored method:
Customization can be available.
Air has huge compressibility, so air inflatable rubber
dam will appear recess when crest overflow, and flow is
concentrated, has strong scour strength for downstream
Medium in air inflatable rubber dam is available easily,
does not freeze in winter.
Air inflatable rubber dam is requested with high
Air inflatable rubber dam can be inflated or deflated
quickly by air blower, and equipment can control the
height of rubber dam casually.
It has simple structure, perfect seismic performance,
completely collapse capability and no water resistance.
It can resistant to sharp objects, pieces of ice, stone
and vibrations caused by river overflowing.
It can easily adapt to potential differential settlement
of the foundation.
It is high volume /low pressure system, so high pressure
compressors are not needed.
Maximum overflow can higher 20% than rubber dam.
The outer rubber layer has excellent weathering, aging,
abrasion, sunlight, UV, heat and ozone resistance.
The middle rubber layer is used for protection of canvas
and for connection of two or more canvas with rubber
The inner layer is used for protection of canvas and has
excellent watertight and airtight.
The canvas has great flexural stress and adhesion
Air inflatable rubber dam can be installed on any channel
cross section shape, and can seal well, without leakage.
Investment of air inflatable rubber dam is lower than
water inflatable rubber dam.
It has short construction time, installation only need 3
to 15 days.
The service life span of air inflatable rubber dam is up
to 15 years, and it is maintenance free, does not have
moving parts and painting.
Divert water for irrigation.
Raise existing dams.
Develop water entertainment and tourism.
