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.

You can find more information on our web, so please take a look.

Features:

• 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 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.

Hengyang supply professional and honest service.
