Rubber dam
Classification:
According to external form: pillow dam, slope dam, arch dam, spine dam, deflect dam.
According to medium: air filling dam and water filling dam
According to anchoring type: single and double anchor
Advantages:
Rubber dam has the following characteristics compared with conventional sluice dam:
1. Low cost and capital input, investment reduced by 30%-70%, save steel by 30%-50%, cement saved by about 50%, wood saved by over 60%.
2. Short construction period: air bladder installation generally need only 3-15 days, the project can be accomplished and attract benefits in the same year.
3. Dam body is made of flexible materials with shock resistance and foundation anti-deformation capability, good sealing effect, complete collapse capability, and no water resistance.
4. Used for urban river construction, the colors and beautiful styles are conductive to create features and beautify the environment.
5. The service life is designed up to 15 years, usually with less maintenance and management convenience.
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.
