Shield Type Rubber Dam with Modular Design

Shield type rubber dam, also named pneumatic shield type rubber dam, is a new kind of rubber dam integrating the advantages of traditional steel dam and rubber dam. It consists of civil part, embedded components, shield plates, air bladders, pneumatic charging and discharging system. Steel shield plates provide front stop water; rubber air bladders provide support for shield plate; a row of basic anchor bolt and soft connection construct the whole structure of dam; a set of pneumatic charging and discharging system provides operating power to achieve rise dam and lower dam. Shield plates and air bladders are connected with the base by anchor bolts and high strength rubber compound belts. If the gate is fully open, shield plates all lying on the riverbed, not affect navigation. If the gate is fully closed, overflow can form various artificially designed overflow landscape. It is easy to install and repair, has short construction time and long service life. It is widely applied to many fields such as water conservancy, hydroelectricity, water transportation, moisture proof and beautify the environment, etc.

Shield Type Dam (Pneumatic Shield Gate) technology was invented by OBERMEYERHYDRO, INC. in the United States, which utilizes rubber air bladders to support steel shields to retain water. Shield tyoe dam has simple structure, high security, long service life, convenient maintenance and easy replacement, and can be applied to hydroelectric power generation, landscape, irrigation, low head locks, diversion and fish passages, underground garage gates, etc. It can be designed, produced and installed according to the user's requirements, which is favored in countries all over the world, and has a wide range of application space.

Advantages of shield type dam
&#;&#;1. Utilizing rubber airbags to support steel shields to retain water, high safety, long service life (more than 30 years), and significant comprehensive economic benefits;
&#;&#;2. Modularized design can simplify the installation process and reduce post maintenance;
&#;&#;3. no need to set up the middle pier, can continuously extend the gate across the water, can design more than 200 meters long, water retaining height of 10 meters or less, the gate and dam can be completely inverted, to achieve efficient flooding;
&#;&#;4. The steel guard plate can well protect the rubber airbag from floating objects such as ice and mud and debris, prolonging the service life of the airbag, and it can be operated normally in winter in cold areas;
&#;&#;5. The gate system has very little vibration, and can be installed in rivers and spillways with any height of head;
&#;&#;6. It is easy to realize automatic control and control the water level accurately;
&#;&#;7. The control system adopts air as the filling medium, there is no oil leakage problem, and it will not cause pollution of water and the surrounding environment.
