The steel dam landscape weir is a new type of hydraulic structure that combines water conservancy engineering with landscape design, primarily used for river regulation, urban landscape beautification, and ecological protection. Its core design is based on bottom-axis drive technology, utilizing a hydraulic system to control the opening and closing of the gate, achieving the integration of water flow regulation and visual aesthetics.
Structural Features
The steel dam mainly consists of the gate body, bottom axis, hydraulic system, and civil structure. It is constructed using high-strength steel welding with anti-corrosion treatment, while rotating components employ composite materials to enhance self-lubrication and durability. The gate rotates in coordination with the drive crank arm via the bottom axis, enabling stepless opening adjustment and bidirectional water retention functionality.
Functional Applications
Water Regulation: Precise opening and closing adjust water levels, supporting flood control, drainage, and ecological water environment improvement. For example, the Tongren steel dam project ensures sealing through high-quality waterstop rubber and exquisite installation techniques, effectively enhancing river management efficiency.
Ecological Water Storage: During dry seasons, it can store water to form artificial lakes or wetlands, improving the surrounding ecological environment. The Dazhou hydraulic dam project creates artificial waterfall landscapes through an overflow design at the top of the gate, combining water storage and beautification functions.
Intelligent Operation: Equipped with a hydraulic system for remote control and real-time monitoring, supporting intelligent water resource scheduling.
Landscape Advantages
When the gate is open, it forms dynamic water features (such as artificial waterfalls), while when closed, it remains hidden below the water surface, maintaining a clean river appearance. Its structural concealment makes the river space appear more expansive, making it suitable for medium-sized river renovations with water surface widths of 50–500 meters.
