Product Description

The rubber weir is a flexible dam type that uses a rubber fabric bag to inflate or fill it with water and fix it on a concrete foundation. The height of the weir can be adjusted by changing the pressure in the bag, and it can be quickly decompressed when necessary in emergencies. Flood discharge. This kind of control is usually performed automatically. The method is simple and does not require external power. The rubber weir can maintain its own safety under any circumstances, similar to the role of a rubber dam.
 

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:

Advantages of rubber weir

1. The rubber weir is specifically a small rubber dam
2. Reduced manufacturing cost, high cost performance, high comprehensive benefit
3. Easy installation, saving time and consumables
4. The thickness of the dam cloth is uniform, and there is no relatively weak link in the overlapping part and the shortcomings of the overlapping part and the dam body being uneven.
5. Longer service life, using excellent performance of EPDM rubber, corrosion resistance, UV aging resistance, smooth dam shape, even better landscape effect.
6. It is the only rubber weir product that can maintain long-term operation without deformation.
7. Significantly improved production efficiency and timely delivery.
8. Cost reduction, greater investment and overall social benefits.
9. Compared with rubber dams, rubber weirs are smaller in size and are suitable for small and medium river waters.
10. The dam bag is flat and has no "nodal shape" and local "concave-convex" or "bulging" phenomenon in overlapping parts, making the shape more beautiful.
11. The flexible dam material has strong seismic resistance and foundation deformation resistance and good water stopping effect.
12. The beautiful colors and shapes are used for river landscape construction, which is conducive to creating waterscapes and beautifying the environment.
13. Has a variety of water conservancy uses.
14. High safety factor.

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.
