Feature
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 river.
Medium in air inflatable rubber dam is available easily, does not freeze in winter.
Air inflatable rubber dam is requested with high tightness.
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 layers.
The inner layer is used for protection of canvas and has excellent watertight and airtight.
The canvas has great flexural stress and adhesion function.
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.
