        Gas shield dam by the United States OBERMEYER HYDRO company developed, the company in in the United States successfully completed the construction of the world's first gas shield dam. So far the gas shield has been sold around the world, completed about 200 projects in the construction and use.

The gas shield dam combines the advantages of traditional steel gates and rubber dams, and the main part is made up of rubber balls, steel guards and anchoring components. Gas shield dam work, the airbag inflated or discouraged, supporting the rise and fall of the steel guards, thus completing the river or dam upstream water level control. Gas shield dam with high technical content, wide range of applications, can be used in complex mountainous areas more sediment, multi-push quality, more floating objects on the river and spillway, can replace steel gates, automatic flap gate, rubber dam Retaining building.

        Yantai Huawei Rubber Technology Co., Ltd. is the sole agent of flat-type gas shield in China. I can be based on OBERMEYER company's design to provide the appropriate gas shield dam engineering services to complete the gas shield dam engineering consulting, design, construction, guidance installation and maintenance. At present, the gas dam project has been completed in Qinghai, Germany, Kazakhstan gas dam project (2m high, 25m long), Gansu Longxi gas shield project (3.2m long, long 30m) and so on. Construction projects in Dalian Garden mouth tidal gate project (2.5m high, 15m long, a total of 8 spans), uniform gas shield dam project (4.5m high, long 120m) and so on.

        Huawei Rubber also offers product parts related to gas shield dams. I am willing to provide technical support, product information, preliminary design drawings, preferential prices or the entire set of project planning. In order to provide the best solution and equipment for different projects, the customer can provide the following information:

        &#; the maximum upstream and downstream water level

        &#; maximum flow rate of water flow

        &#; Gate top overflow height

Shield Type Rubber Dam with Modular Design

Shield type rubber dam, composed of air filled rubber bladders and steel shield plates, is a novel alternative to traditional rubber dam. It is ideal for channels, spillways and other various applications with sediment, bedload and floating debris.

Features:

Shield type rubber dam

• Modular design for easy installation.
  Modular design means that the each piece of steel plate corresponds to a rubber supporter. Thereby, there is no need to concern about the overall position of the rubber dam during installation. So the modular design make  installation easier and saves your time and labor.
• Easy to repair.
  Normally, it is considered to be tiring to repair the whole body of air filled or water filled rubber dams. However,  shield type rubber dams are easy to repair in that you can only replace the broken part instead of the whole bladder. In this way, the modular design brings a considerable saving to our customers.
• Suitable to watercourse in any span.
  Whether it be narrow or wide span of watercourses, the shield type rubber dam can be applied without central piers.
• A longer service life
  The hard steel shield plate can not only mark the height of retaining water, but also insolate the soft rubber bladder against water. In this way, the shield protects the rubber bladder from the sharp objects and extends the service life of dam.
• Multi-level applications.
  Shield type rubber dams are ideal for water retaining structure, hydraulic power system, urban landscape, irrigation, water and flood diversion and various applications.
  • Power system: Shield type rubber dam can enhance the power generation capacity of hydropower station by retaining a high water level of upstream up to 0.5m above the top of steel sluice plate. In winter, the shield can effectively prevent the ice from stoppage of power station.
  • Water retaining: The dam can balance the flood discharge ability and the water level of upstream. Meanwhile, you can low the steel shield panel without any affecting of the reservoir&#;s level and power generation efficiency when the flood discharge ability of the spillway is deficient 
  • Navigation: The shield type rubber dam with simple structure can be used as an excellent sluice gate when the ship is driving up or down the river. It allows ships to pass through smoothly by means of lowing the steel shield plates.
  • Irrigation: The dam can provide accurately control over the waterhead and flow capacity of the irrigation channels to ensure the uniformity of water distribution.
  • Flood & water diversion: The shield type rubber dam can adjust automatically to maintain a low level of upstream to divert the flood as well as let the deposition of sediment be washed away.

Shield type rubber dams are ideal for water retaining and hydropower generation.
