water-filled rubber dam

Specifications: 1.made of high-strength synthetic fabrics 2.compound rubber supported by a frame 3.large span sluice. Material of rubber dam: The rubber dam tube is made of strength canvas and rubber layer which ensure tightness of the rubber layers. The rubber layers encompass outer, middle and inner elements for different functions.

This kind of rubber is well resistant against sharp objects, pieces of ice, stone and vibrations caused by river overflowing. The outer layer is made of the special rubber material characterized wear, sunlight, heat and ozone-resistance. The middle 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 characterized watertight and airtight features. Advantages: 1.Rubber dams can be fully deflated to pass high flows without any obstruction. 2. Can be filled air or water 2.A rubber dam can easily adapt to potential differential settlement of the foundation.

3.Rubber dam are high volume /low pressure system, so high pressure compressors are not needed 4.Simple and inexpensive operating system. 5.Rubber dam work well in cold temperature-no need to de-ice,(-15 to +80C as per different materials) no jamming of mechanical parts. 6.No lubrication of moving parts ,no painting required 7.

Rubber dam don’t have leaking seals that tend to be an issue with other gate structures. 8. Easily absorbs impact shock and vibration 9. retain water 10. protect the environment Rubber Dam are divided into air inflatable type and water inflatable type according to medium filled.
