Rubber Dam
The Sunny rubber Dam, also known as Sunny rubber water gate, Sunny barrage, Sunny rubber dam, is made of high-strength synthetic fiber fabric as the force skeleton, which is coated with rubber inside and outside as protective layer, and processed into rubberized cloth. The dam bag, which is anchored to the bottom plate in a closed shape, is filled with water (gas) to form a bag type dam. The dam crest can overflow, and the height of the dam can be adjusted as required to control the upstream water level so as to provide benefits such as irrigation, power generation, shipping, flood control, and tide blocking.

Product Advantages

- Low cost and less investment: it can reduce the investment of 30% to 70%, greatly saving the consumption of three materials-steel, cement and timber, including: steel saved by 30% to 50%, cement 50%, more than 60% of timber.

- Short construction period: the installation of dam bag takes only 5 to 15 days, with a short cycle, and fast benefit.

- The flexible material of dam body has strong anti-seismic and anti-basic deformation ability and good water stop effect.

- The single-dam span is large, and there is no need for too many structures such as piers in the middle, it does not block water, and it is fully collapsed and safe for flood-discharge.

- With beautiful colors and sculptural shapes, it is used for the construction of river landscapes, which is conducive to creating waterscapes and beautifying environments.

- The entire dam bag made by Sunny Rubber possesses new technology for rubber dams that are not deformed for a long period. The advanced one-time molding and vulcanizing technologies used by the company have outstanding advantages in terms of overall performance, stability, and no splicing safety risks. The service life of the dam bag can be 10-15 years longer than that of the spliced rubber dam.
