The Inclined-Wall Inflatable Rubber Dam (also known as Slope Type Rubber Dam) is specifically engineered for hydraulic projects where the riverbanks or abutments are constructed with inclined concrete walls instead of vertical sidewalls.
This configuration allows the rubber dam bag to integrate directly with sloped side structures, making it a practical solution for single-span installations and river channels with geometric constraints.
The dam body is fabricated from high-tensile synthetic reinforcement fabric, coated with EPDM or chloroprene rubber layers for sealing and environmental resistance. It can be designed as either air-filled or water-filled depending on project requirements.
Design Characteristics
Unlike vertical-wall systems, the inclined-wall structure:
- Anchors along sloped abutments
- Adapts to non-vertical concrete sidewalls
- Reduces structural modification requirements
- Simplifies integration with existing riverbanks
- When inflated, the dam forms a stable water barrier.
When deflated, it collapses along the slope and foundation slab, restoring full discharge capacity.
Key Advantages
1️⃣ Ideal for Sloped Riverbank Structures
This type is particularly suitable when:
- Sidewalls are constructed at an angle
- Civil works already include inclined abutments
- Retrofit installation is required
- Single-span configuration is preferred
2️⃣ Simplified Manufacturing
Compared to more complex structural types:
- Easier fabrication process
- Reduced structural shaping complexity
- Cost-effective production
3️⃣ Flexible Hydraulic Performance
- Effective water retention
- Rapid inflation and deflation
- Suitable for seasonal water management
- Compatible with pneumatic or hydraulic filling systems
4️⃣ Short Installation Period
- No heavy lifting towers
- No complex mechanical gate systems
- Typical installation: 3–15 days
Engineering Considerations
While practical and cost-efficient, inclined-wall dams require careful design attention:
- Wrinkling may occur near slope transition lines if not properly tensioned
- Stress concentration may develop near upper slope anchoring points
- Multi-span projects may require larger intermediate piers, potentially reducing flood discharge efficiency
Professional engineering design ensures safe long-term operation and mitigates these factors.
Typical Applications
- River regulation projects
- Irrigation control structures
- Small hydropower diversion systems
- Urban water landscape projects
- Retrofitting existing sloped riverbanks
