Hydraulic dams, also known as hydraulic steel dams, are innovative water control structures designed for flexible regulation of water levels in rivers, canals, and water conservancy projects. Typically composed of key components such as a steel dam face (the water-retaining structure), hydraulic cylinders, a pumping station, control system, and foundation anchoring devices, these dams leverage hydraulic power to achieve precise operation. The steel dam face, usually made of high-strength alloy steel, is connected to hydraulic cylinders that are mounted on concrete foundations or side piers. The operational principle is driven by hydraulic pressure: when water storage or level elevation is required, the pumping station supplies oil to the hydraulic cylinders, which extend to push the steel dam face upward, forming a barrier that retains water upstream. Conversely, when water release is needed (for flood control, downstream water supply, or maintenance), the hydraulic cylinders retract under controlled pressure, lowering the dam face to allow water to flow through. This lifting and lowering process is smooth, adjustable, and can be precisely controlled via automated or manual systems. Hydraulic dams are widely applied in various scenarios, including river regulation to maintain stable water levels, irrigation to store water for agricultural use, flood control to manage sudden water surges, and urban water landscapes to create aesthetic water features. They are particularly suitable for areas where both water storage and unobstructed flood discharge are required, as their retractable design minimizes interference with natural water flow during high floods. Compared to traditional concrete dams or rubber dams, hydraulic dams offer notable advantages: they have a longer service life due to the durable steel structure; their rigid dam face provides better resistance to impacts from floating debris; the hydraulic system enables quick response and precise regulation; and they require relatively low maintenance. Additionally, their modular design allows for easier expansion or renovation according to changing project needs. In summary, hydraulic dams represent an efficient, adaptable solution for modern water resource management, combining structural robustness with flexible operation to meet the diverse demands of water regulation, flood control, and environmental enhancement.
Auxiliary Sealing Components
Water-swellable rubber is used at panel joints to adapt to minor deformations of the dam body. Adjustable water stop pressure plates are installed on the bank wall side to compensate for installation errors.
(5) Control System: Operational Core for Intelligent Regulation
Monitoring and Sensing Components
Angle Sensor: Real-time monitors the flipping angle of the dam face and feeds back to the control system to adjust the lifting position.
Float Switch: Detects water level changes and triggers the automatic opening and closing of the hydraulic system to realize unattended operation.
Control Terminal
Local Control: Equipped with buttons, indicator lights, and a PLC controller (referring to the automatic control system of steel sluice gates), allowing manual adjustment of the dam height.
Remote Control: Accesses the basin management and control platform via a communication module to realize multi-dam linkage and remote monitoring, with a command response time of ≤ 3 seconds.
2. Functional Correlation Characteristics of Structural Design
(1) Adaptation of Mechanical Structure to Flood Control Safety
Stability Advantage of Triangular Support
The triangular structure formed after the dam face is lifted converts water pressure into axial pressure and transmits it to the foundation. Its flood impact resistance is superior to that of traditional flap dams, and the dam body will not be damaged by freezing in northern winters.
Optimized Design of Flow Pattern
After the dam face is lowered, it is only 20 cm higher than the foundation, basically maintaining the original riverbed shape. The flood discharge capacity is close to that of a dam-free state, enabling rapid discharge of sediment and floating debris.
(2) Integration of Structure and Maintenance Convenience
Modular Design
All components adopt factory prefabrication and on-site assembly, reducing concrete work volume. The construction period is shortened by more than 40% compared with traditional sluices.
Easy Maintenance Characteristics
The hydraulic system and sealing components are easy to replace. When the anti-corrosion coating of the panel is damaged, it can be repaired by referring to the repair process of steel sluice gates. The maintenance cost is only 1/3 of that of rubber dams.
3. Summary of Key Structural Characteristics
Structural Unit | Core Advantage | Connection with Steel Sluice Structure |
Panel & Bottom Shaft | Flip design, strong flow passage capacity | Common anti-corrosion technology for materials |
Hydraulic Drive System | Direct drive, fast response | Reference for pump station maintenance and antifreeze measures |
Triangular Support System | Mechanically stable, strong impact resistance | Similar force optimization logic to sluice gate beams |
Sealing System | Modular sealing, low seepage rate | Consistent material and pressing principle for water stop strips |
Intelligent Control System | Automatic regulation, adapted to flood rise and fall | Reusable sensor and PLC control technology |
4. Scene Adaptability of Structural DesignSediment-Laden Rivers: A sediment discharge channel is reserved in the bottom shaft. After the panel is lowered, it fits closely to the riverbed to prevent sediment accumulation from affecting opening and closing.
Cold Regions: Steel panels use low-temperature tough steel; antifreeze fluid is added to the hydraulic system; the triangular structure can resist ice pressure.
Urban Rivers: Arc-shaped panels are combined with color coating to form a waterfall landscape when the dam is lifted. When the dam is lowered, it does not affect navigation and flood control.
