Structural features:
The integral rubber dam, also known as a non-overlapping rubber dam, is made of framework material (Nylon Fabric) and inner and outer covering rubber according to the molding process and one-time vulcanization process.
There is no repeated process of secondary vulcanization and secondary splicing for the whole rubber part through the entire rubber dam body.
The thickness of the rubber membrane is even, the strength is consistent, there is no weakness in the lap joint section, and the safety factor is high.membrane.
The strength of the dam bag in warp and weft direction is consistent, and there is no weakness
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.
Air inflated rubber dam data
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.
