In recent years, drought, floods and other extreme natural disasters occur frequently, and the discharge capacity of the river water becomes particularly important, rubber dam have played a vital role in society. 

In the past, rubber dam was mainly used for irrigation and power generation. With the development of rubber dam technology slowly applied to life all around has been widely used.

Rubber dam is a new type of hydraulic structures which appeared in 1957. Qingdao Huaming rubber dam instead of the dams since ancient times of earth, wood, steel tape, stone and other building materials, the use of similar conditions and sluice. Compared with the conventional gate, has the following characteristics: simple structure, can fill dam, dam collapse flood, by nature without destroying nature; save three material, can save about 50% 30%-50% steel, cement, wood more than 60%; the construction period is short, the dam bag can be installed in 3-15 days, most of the rubber dam project is the year when the benefit of construction.

Because of the good compressibility of gas, inflatable rubber dam in the overflow, the presence of the notch phenomenon, water concentration, strong on downstream river erosion. In the frozen area, there is no ice in the air filled rubber dam.

In recent years, many areas were China rain, because the dam inadequate spillway capacity loss caused by the rubber dam is too many to count, to solve the traditional problem of dam flood discharge capacity, filling rubber dam dam in water or air, filling up when the water, when the dam collapse flood, completely collapse, flood discharge capacity and with the automatic control system can automatically adjust the height according to the water level, the people's life and property safety are guaranteed.

The technology development and application of rubber dam has injected new life, and quickly become the productive forces of new technology, the powerful into the domestic and foreign markets to create a good condition and provide a strong guarantee.
