Product Description
General intruduction:
The rubber gate is made of high-strength synthetic fabrics and compound rubber supported by a frame and prefabricated rubber,riveted on the base board to form a sealed bag-shaped space inflated with water or air in droughts seasons to store water for industrial,agricultural and household water consumption .In rainy seasons,water caontained in dam shall be discharged to help relesae flood water from the river course.Advantages of rubber dam are shorter construction period(3-15 days for installation and the final construction period 3-6 months),30-70% less engineering budget than that of civil works for cements,steel and logs,extended service life,simplified maintainance and improved vibration resistance.
Use scope:
This rubber gate is suitable for the projects with lower water level and large span sluice widely used for irrigation, power generating, flood control and urban landscaping.
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.
Medium of filling:
Rubber gates are divided into air inflatable type and water inflatable type according to medium filled.
The rubber bladder is made of strength canvas and rubber layers. The canvas serves as the force-bearing frame of the dam with good flexural stress resistance and excellent adhesion function. The rubber layers consist of out-layer, middle-layer and inner-layer to protect the canvas.

Automatic control system
The automatic control system consists of computer software technology, PLC control technology, communication and transmission technology and sensor test technology etc. The system can automatically adjust the inflation and deflation of the tubes according to the water level, which can be used in daily operation and flood emergency control for the safety of the dam. Parameters can be set and adjusted remotely through monitoring software for video surveillance and daily management. The system can also be controlled through mobile phone SMS. One control system can manage several tube dams in a river.
Huahai has offered more than 4000 rubber dams throughout China and in Vietnam, Bangladesh and Iran and Indonesia etc. Our company attaches significance to customer satisfaction and credit business philosophy and offers quality products and reliable after-sales services to customers.
Customers can choose different types for different needs, and we can supply customers with technical materials and special support .
