• 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.
