Advantages of shield type dam-青岛华明工业科技有限公司

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.

Gas shield dam, also called pneumatic shield gate, is a new type of gate that synthesizes the advantages of traditional steel gates and rubber dams, consists of shield plate, embedded parts, airbag and pneumatic system. The shield plate is a row of reinforced steel plates, the airbag is supported in the downstream side of the steel plates. Inflation or exhaust of the airbag is utilized to control the undulation of the shield plate and block the water, which can precisely control the angle of the shield plate.

Advantage&#;

1, the structure is simple, easy to install. Modular, modular structure without the need to use large construction equipment, saving manpower, material resources, financial resources, the construction period is small.
2, with full security. Steel shield plate fully protect the rubber dam bag, the dam bag can provide sufficient buffer, do not fear the sudden impact of large floating objects.
3, ecological landscape effect is good. The overflow will form a waterfall, very beautiful.
4, the management of low operating costs. Running will not happen card hanging, no regular maintenance.
5, cleaning sludge discharge capacity. Collapse of the dam when the shield completely affixed to the base of the board, water resistance height of less than 9 cm.
6, strong seismic capacity. Shield plate and the foundation is a soft connection, will not cause system failure and loss of normal operation ability.
7, a wide range of application. Suitable for various hydrological conditions of the river, suitable for the construction of urban beautification. Can be directly applied to the transformation of a variety of rubber dam, automatic dam.
