Air-supported Barrier Dam - Quick Deployment, Perfect for Temporary Water Retention in
Shield Plate
Constructed from high - quality materials such as stainless steel or carbon steel (with surface treatment like polyurea coating or hot - dip galvanizing for corrosion resistance), the shield plates are designed to withstand significant water pressure. Each unit is typically 5m in length, and they are connected by high - strength rubber composite belts, allowing for flexibility while maintaining structural integrity.
The plates are thick (usually 16mm or more) and feature an arc - shaped design on the water - facing side, with welded reinforcement ribs to enhance strength and durability.
Inflatable Airbag
Composed of multiple layers of NN66 or aramid skeleton materials and special rubber, the airbags are manufactured using patented technologies. They have a high - performance rating, with a working pressure typically ranging from 0.7 - 0.8MPa. The design safety inflation pressure is set at 8 kg, providing a safety factor 15 times that of traditional rubber dams.
The outer layer of the airbag is made of EPDM polymer, which has excellent weather - resistance and ozone - aging resistance, ensuring a service life of over 50 years.
Control System
The control system is responsible for regulating the inflation and deflation of the airbags. It can be automated, allowing for precise control of the dam's height and water level. Even in the absence of electricity, the system can be configured to accurately and automatically control the water level, which is particularly advantageous for applications such as hydropower generation.
The system uses air as the inflation medium, eliminating the risk of oil leakage and subsequent pollution to water and the surrounding environment.
Simple Structure and Easy Installation
The modular and unitized structure of the air shield dam simplifies the installation process. There is no need for large - scale construction equipment, which significantly reduces labor, material, and financial costs. The installation period is relatively short, enabling quick project completion.
High Safety
The steel shield plates provide robust protection for the rubber dam bags. In the event of sudden impacts from large floating objects, the dam bags can provide sufficient buffer force, ensuring the safety and integrity of the dam structure.
Excellent Ecological and Landscape Effects
When water overflows from the dam top, it creates a beautiful waterfall - like effect, enhancing the aesthetic value of the surrounding area. This makes the air shield dam an ideal choice for urban beautification projects and improving the ecological environment.
Low Management and Operation Costs
During operation, the air shield dam is less prone to problems such as jamming or hanging. As a result, it requires minimal maintenance and repair, reducing long - term management and operation costs.
Powerful Debris and Silt Discharge Capacity
When the dam collapses, the shield plates lie completely flat against the foundation, with a water - blocking height of less than 9 cm. This design allows for efficient discharge of debris and silt, maintaining the normal flow and ecological balance of the river.
Strong Earthquake Resistance
The soft connection between the shield plate and the foundation enables the dam to better adapt to foundation deformation. Even in the event of an earthquake or ground movement, the system can still function properly, without losing its normal operating capabilities.
Wide Application Range
The air shield dam is suitable for various complex hydrological conditions in rivers. It is also well - suited for urban beautification projects and can be directly applied to the renovation of existing rubber dams and automatic flap dams, providing a cost - effective solution for upgrading water - retaining structures.
