Rubber dam of Dawen River Treatment Project in Taian, Shandong

Rubber dam is an important technology in hydraulic engineering, also known as rubber gate. It uses high-strength synthetic fibers, so it has a strong load-bearing capacity. The rubber dam has the advantages of simple structure, good seismic performance, short construction period, and flexible operation and management. Therefore, it is widely used in the construction of water conservancy projects, and plays an important role in ensuring the sustainable development of water conservancy and hydropower projects and promoting the development of the national economy. Advantages of rubber dam:

1. Save material, good performance

The use of rubber dams in water conservancy projects will greatly reduce the consumption of steel, wood and cement. The main material of the rubber bag is the flexible structure of rubber products and synthetic fiber fabrics, which can well replace the structure of steel, wood, and brick. Since there is no need to install hydraulic structures such as steel bricks on hoisting machinery, middle piers, and working bridges during construction, the use of rubber dams can greatly reduce the use of steel, cement, and wood. In the entire rubber dam construction process, except for the structure of the rubber cloth, other materials are made of water and air, so it can show a good water blocking effect.

2. Low cost and simple structure

Rubber dams are low in cost and simple in structure, and generally do not need any support in the middle in practical applications. Since the operating system uses manual gate valves and lacks related arm lifting equipment, it can save engineering costs to a large extent.

3. Simple construction and easy operation

In the actual construction of the rubber dam, the dam bag does not need to be made by itself, but only needs to be wholesaled from the factory according to actual needs. In the specific installation process, the installation speed is relatively fast, and it can be completed in 3 to 15 days, which is conducive to shortening the entire construction period.

4. Flood control safety

The actual application of the rubber dam will not have adverse effects on the actual operation of the water conservancy project, and the dam bag of the rubber dam is generally tightly attached to the bottom plate when it is not working, which can effectively save space. If other operations are required, there is no need to renovate the original project. The dam bag has an obvious water-stopping effect, and there will be no water leakage problems, which can effectively ensure the flood control safety of water conservancy projects. The maintenance work is relatively simple. The rubber dam is easy to install and has a simple structure. It only has drainage function and water filling function. Under normal circumstances, these devices seldom fail, and the related maintenance work is very simple and convenient, so rubber dams are widely used in the construction of water conservancy projects.
