Huahai - Model JBD1.0-80-2 -Rubber Dam

A rubber dam is formed by pumping air or water into the body. The air is supplied from an air blower and water can be supplied from the mains or through a pump. Generally, the filling and discharging time of water filled rubber dam is longer than that of air filled rubber dam. The cost of these two kinds of rubber dams is similar. Rubber dam can be divided into pillow type rubber dam, inclined rubber dam, rubber dam with spoilers, fin rubber dam, arc rubber dam collapsible weir. Rubber dam project includes rubber dam bag, anchorage system and filling and discharging control system. The rubber dam is easy to operate and is extremely durable. Rubber dam project has short construction period and low overall cost. A lightweight structure of rubber dam means better earthquake resistance.

Although the rubber dam is rarely repaired, unlike the conventional steel gate, which needs to be painted regularly to prevent rust. Regular inspection of rubber dam should be carried out, especially after the flood. It is necessary to check whether there are any floating objects or debris causing stabbing damage to the dam bag, as well as the damage caused by the vibration of the dam body, the abrasion of the dam bag and the concrete foundation, and the friction of stones in the river against the dam bag. Rubber dam is easy to be damaged by sharp objects, so the management scope and safety area of rubber dam project should be defined on site.

In the 1950s, in order to meet the needs of industrial and agricultural production, rubber dam came into being. The rubber dam is a permanent structure which is formed by pumping air or water into the dam body. The dam body is made up from layers of fabric which are coated with synthetic rubber. Since 1994, HUAHAI has been involved in the design, supply and manufacture of rubber dams and spillway gates around the world. Compared with other stone and steel dams, the most prominent feature of HUAHAI rubber dam is that the dam body is fabricated in one piece at the factory and rolled up for easy transportation to site, which shortens the construction period.

Rubber dam has the advantages of low cost, simple structure, short construction period, good earthquake resistance and no water blocking. It is widely used in agricultural irrigation, groundwater recharge, river regulation, power generation, urban beautification, and etc. It can improve the utilization rate of water resources and reduce the use of conventional gates. Rubber dam has been widely used in China since 1960s.
