Gas shield dam introduction - 气盾坝
Gas shield dam, also known as pneumatic escape gate, gas shield type steel dam, is following the rubber dam after another new retaining dam.
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:

OPERATION PRINCIPLE
1.
Raising Dam:
the air bag is inflated to support the water shield plate to realize the water storage operation;2.
Overflow
: when the water level exceeds the height of the gate panel, the water flow and floating objects cross the panel, and the air bladder and support system are hidden under the gate panel to be fully protected;3.
Dam height
adjustment: adjust the support angle of gate panel by adjusting the inflation pressure to control the required water retaining height;4.
Dam collapse:
by discharging the air bladder, the gate panel and air bladder lie flat on the concrete foundation of the riverbed floor, and the support system is completely covered by the gate panel, so the rubber air bladder under the safe condition to avoid damage by the sharp floating object.5. All the above operation are equipped with manual and automatic "dual control" system.
STRUCTURE
Unique features
1. Accurate water level control;
2. Modular structure, easy installation and maintenance;
3. The air bladder is fully protected by gate panel in all directions, and is not damaged by water, sediment, rolling stones, floating objects and ice edge (including strong ultraviolet radiation), and its service life is longer;
4. Scientific supporting structure, safe and stable operation;
5. It can fully meet the design requirements of 8-10m dam height;
6. The trajectory bucket type energy dissipation is good: the water flow is even and the overflow drop is large, which can form a more magnificent waterfall landscape;
7. lt can be directly reconstructed on the old foundation and weir crest such as rubber dam and concrete flap dam, which can greatly reduce the cost of reconstruction project.
Gate Panel
Material:
stainless steel, carbon steel
Size:
5m or 6m per unit
Structure:
made of steel panel above 16mm thickness, arc, reinforced ribs on the surface
Corrosion protection:
thermal spray zinc and seal coating or polyurea material.
Air Bladder
Material:
Air bladder is made of tyre fabrics and special rubber.
Performances:
W.P. 0.07-0.20MPa, designed pressure 1.0MPa, designed safety factor 8-10 times, out layer EPDM, aging resistant over 30 years.
