Product Description

Company profile 

Yantai Sunny Rubber Co., Ltd established in 2005, located in Economic Development Area of Qixia City, Shandong Province. It is high-tech enterprise. Main products are pneumatically operated spillway gate, rubber dam, filter belt, conveyor belt, etc.

The workshop is 22,000 square meters, equipment 200 sets, worker 230. It owns 11 patents for invention, 18 patents for utility. With the full capacity of design, production, installation and after sales, more than 100 spillway gates were built by Sunny in domestic, for power plant impounding and river management. Our products have been also exported to Italy, Thailand, Philippines, South Africa, and Argentina etc.

We have been designing, developing, manufacturing and installing customer order-made Rubber Dams worldwide since 2008, using the highest grade rubber and internationally recognized quality components. We have been in success of research & development of 6 meters and higher pneumatic spillway gate, to reach the highest level of   technology in the world today.






A Rubber Dam is a highly efficient water controlling structure with a permanent structure comprising a sheet of rubber-coated fabric (rubber body) which is fixed to a reinforced concrete foundation using clamp plates and anchor bolts. The rubber dam is inflated by pumping air or water inside the rubber body until the design height or pressure is reached. It is deflated by allowing the air or water inside the rubber body to escape.

The whole dam air bag strength

The whole dam airbag, also called none overlap joints dam airbag. It produce according to the whole manufacturing technology, which realized by the super large curing press and the patented technology of folding and curing the sulfide. The whole dam bag has no second time splicing and vulcanization process, and the tensile strength of all directions can be consistent, so there is no obvious weak part, which will improve the safety greatly. The service life is fully guaranteed.
1. No weak parts in overlapping, obviously improved in performance, safety and reliability.
2. Flat dam airbag, without "knots" and "bump" phenomenon, more beautiful.
3. The production efficiency is greatly improved, and the delivery is short.
4. Reduce the cost, and increase the investment and comprehensive social benefits.


Features:

• 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 performance, completely collapse capability.
• It can resistant to sharp objects, pieces of ice, stone and vibrations caused by river overflowing.
• It can be easily installed to potential differential settlement of the foundation.
• 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.
• 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.
