Pneumatic Rubber Dam - Adjustable Water Retaining for Small to Large-Scale Water Works

Rubber Dam: Multi functional Water Conservancy Engineering Solution

Rubber dams, as innovative facilities in modern hydraulic engineering, are widely used in various hydraulic projects worldwide due to their unique design and excellent performance. It uses high-strength synthetic fiber fabric as the load-bearing skeleton, coated with rubber as the protective layer inside and outside, processed into adhesive tape and anchored to the bottom plate, forming a closed dam bag. By inflating it with water or gas through the filling and discharging pipeline, a sturdy bag type water retaining dam is constructed.

Excellent features, showcasing advantages

Cost Economy: Compared to traditional gate dams, rubber dams can reduce investment by 30% -70%, significantly saving materials such as steel, cement, and wood, effectively reducing project costs.

Efficient construction: The installation of dam bags is fast and can be completed in only 3-15 days. Most projects can be put into use in the same year of construction, quickly realizing their benefits.

Flexible seismic resistance: The dam body is a flexible soft shell structure with excellent seismic performance, which can effectively resist impacts such as earthquakes and waves, ensuring stable operation under complex geological and climatic conditions.

Not blocking water and having good waterproofing: The dam bag is tightly anchored, achieving almost zero water leakage. During the flood season, after the water in the dam bag is emptied, it can tightly adhere to the bottom plate without reducing the cross-section of the riverbed or obstructing the flow of water, ensuring smooth flood discharge in the river channel.

Easy maintenance: The normal service life of rubber dam bags can reach 15-25 years, with less daily maintenance needs and convenient management, reducing long-term operating costs.

Diversified applications to meet needs

Reservoir spillway: As a gate or active overflow weir, it increases the reservoir capacity and power generation head, optimizing water resource utilization efficiency.

River engineering: used as a low head, large-span rolling dam or overflow weir, without the need for conventional gate opening and closing machines and work bridges, simplifying the engineering structure.

Canal system facilities: Flexible water storage and precise adjustment of water level and flow at positions such as inlet gates, branch gates, and control gates to ensure stable irrigation and water supply.

Coastal protection: Construct wave barriers or tidal barriers, which are more durable than metal gates due to the rubber material's resistance to seawater erosion and the impact of marine life.

Ship lock application: Suitable for upstream and downstream gates of ship locks with large spans, enhancing the flexibility of ship lock operation.

Construction cofferdam: The height of the rubber movable cofferdam can be raised and lowered as needed, and it can overflow from the top of the cofferdam without the need to take soil to build the cofferdam, keeping the river clean, saving manpower, and shortening the construction period.

Landscape: The colorful dam bags have beautiful shapes and smooth lines, adding unique scenery to urban landscaping projects and enhancing the quality of urban landscapes.
