Rubber dam is a new type of hydraulic structure compared with steel sluice gate, and made of high-strength fabric adhering with rubber, which forms a rubber bag anchoring on basement floor of dam.
Filling water or air into the dam bag, rubber dam is used for water retention. Emptying water or air from the dam bag, it is used for flood release. Rubber dam has many advantages compared to conventional weirs, such as low cost, simple hydraulic structure, short construction time, perfect seismic performance and effect of stopping leading, and low resistance to water flow in flood season.
Types of rubber dam:
Rubber dam are divided into air inflatable type and water inflatable type according to medium filled.
(1)air inflatable rubber dam (2) water inflatable rubber dam
Rubber dam are divided into pillow-like dam and inclined dam according to form of dam tube.
(1) pillow-like dam (2) inclined dam
Material of rubber dam
The rubber dam tube is made of strength canvas and rubber layer which ensure tightness of the rubber layers. The rubber layers encompass outer, middle and inner elements for different functions.
This kind of rubber is well resistant against sharp objects, pieces of ice, stone and vibrations caused by river overflowing.
1: How can I choose the most suitable machines ?
A: Please tell me your specifications (Gate type/height/width) or send us the products drawing ,we will choose the most suitable machines for you .
2: What's your main products of your company?
A: We specialized in series of movable dams used in water resources management field,including hydraulic elevator dam, simplified elevated dam,movable flood wall.Hydraulic elevator dam is our main product, it is a low-head water retaining gate, which is driven by hydraulic cylinder with small angle support, it lifts to remain water and drops to discharge water.
It is applicable to various geological and hydraulic conditions, and can be widely applied in water conservancy and hydropower, water ecological civilization construction, and urbanization construction scenarios such as river landscape with a height of 1-5 meters, irrigation and water storage, reservoir expansion, river and lake ecological water storage, etc. It is also particularly suitable for mountainous areas where floods rise and fall, as well as rivers with high levels of floating debris and sediment accumulation during ice storage.
5: Where is our factory located? How can I visit there?
