Product Q&A

Q:What is the design lifespan of the Pneumatic Shield Dam and its rubber airbag?

The steel shield structure is designed for a lifespan of over 50 years with proper anti-corrosion treatment. The high-strength EPDM rubber airbag typically lasts 20-30 years, depending on water conditions and maintenance. We use multi-layer composite materials to ensure puncture resistance and aging resistance.

Q:How does the dam perform during extreme floods or freezing winters?

It is highly reliable in extreme conditions. During floods, the dam can collapse completely within minutes to allow maximum water discharge. In winter, the rigid shield supports ice loads effectively, preventing damage common to traditional rubber dams, and allows for stable ice sheet formation upstream.

Q:Is the installation complex and how is the dam controlled?

Installation is modular and faster than civil concrete dams, requiring less foundation work. The system is fully automated using a PLC control system that monitors water levels and air pressure in real-time. It can be operated remotely via computer or mobile app, requiring minimal manual intervention.
