Pneumatic Shield Dam: The "Intelligent Hydraulic Guardian" for Water Retention and Flood Discharge

Composed of a water-retaining shield, rubber airbags, anchoring system, safety restraint belts, and air inflation/deflation system, the pneumatic shield dam is a new type of dam developed by integrating the advantages of traditional steel gates and rubber dams.Its main features include a modular structure, which is suitable for hydraulic engineering projects of varying spans and eliminates the need for pier connections. It holds an absolute advantage especially in sluice and dam projects with large spans, low water heads and compact layouts. Not only does it meet the functional requirements of conventional sluices, but it can also harmonize with the surrounding environment, fully satisfying the ecological and landscape-oriented demands of modern hydraulic engineering. It can be applied to river courses and reservoirs, as well as to projects such as seawalls, artificial landscapes, water diversion and irrigation, drought prevention and flood drainage, and the heightening and widening of existing dams.

The Core Competitive Advantages of Qingdao Huahai Pneumatic Shield Dams

  1. Simple Structure & Easy Installation: The pneumatic shield dam eliminates the need for complex gate hoisting equipment, featuring low difficulty in foundation construction and a short installation period, which significantly reduces the project construction costs and timeline.

  2. Low Maintenance Costs & Long Service Life: The dam bags are made of high-quality materials with excellent weather resistance and are not prone to aging or damage. The equipment has few moving parts, resulting in minimal daily maintenance work, and a service life of over 20 years.

  3. Strong Adaptability & Environmental Friendliness: It is suitable for rivers and reservoirs with various geological conditions and has little impact on the surrounding ecological environment. The flexible structure of the dam can adapt to foundation settlement, possesses good impact resistance, and can effectively withstand water erosion and floating object impacts.

  4. Intelligent Control & Easy Operation: Equipped with an advanced automatic control system, it enables remote monitoring and automatic inflation/deflation. Operators can complete operations such as water retention and flood discharge through the control console, reducing manual labor intensity.

  5. Comprehensive After-Sales Service & Reliable Quality Guarantee: Huahai has a well-established after-sales service system and a dedicated after-sales service company, providing full - cycle support during the pre - sales, in - sales, and post - sales stages. The company's technical and after - sales personnel will promptly answer technical and other questions raised by customers. Based on customer needs, installation personnel can be dispatched to the site to guide the installation until the equipment is installed and commissioned successfully. After the completion of the pneumatic shield dam installation, Qingdao Huahai Environmental Protection Industry Co., Ltd. will provide customers with the operation specifications of the pneumatic shield dam. In addition, after - sales service personnel will be arranged to conduct on - site return visits 1-2 times a year to assist customers in managing and using the pneumatic shield dam equipment properly. The service life of the dam bag is 20-25 years. For the pneumatic shield dam equipment installed by Huahai in China, if any operation - related problems occur, the company will send installation personnel to the site for guidance in a timely manner upon receiving customer notifications.

Wide Application Scenarios, Empowering Diverse Water Conservancy Projects

The pneumatic shield dams manufactured by Qingdao Huahai Environmental Protection Industry Co., Ltd. are not only widely applied in water conservancy projects across numerous provinces and cities in China, but also extensively used internationally. Their main application scenarios include:
