Segmented Hinged Structure : The dam consists of multiple hinged panels, and the size of single panel can be flexibly customized.
Independent Control of Each Panel : Each dam segment can be lifted or lowered separately to realize local water storage and discharge, providing flexible water regulation modes.
Low Foundation Layout : No deep and massive gate piers are required with shallow buried foundation, which greatly cuts civil construction costs of river channels.
Full-flush Riverbed Flow Passage :When fully collapsed, the dam fits closely to the riverbed without narrowing the flood section, ensuring smooth flood discharge in flood seasons.
Automatic Silt & Sediment Scouring : High-speed water flow scours sediment deposits in front of the dam during operation, eliminating frequent manual dredging for long-term service.
Bidirectional Water Pressure Resistance : It can withstand water heads from both upstream and downstream, suitable for water control projects in tidal rivers and backwater channels.


Stepless Lifting Adjustment : The dam can be locked at any angle between 0° and 90°, achieving precise control of water storage level and discharge flow.
Stable Hydraulic Driving : Each panel is equipped with an independent hydraulic cylinder, delivering smooth lifting without impact, shaking or deformation.
Excellent Water Sealing Performance : Rubber waterstops are installed at panel joints and the bottom to minimize leakage and reduce water loss.
Attractive Landscape Effect :Water overflow over the upright dam forms continuous waterfalls, which can be matched with lighting to build urban waterfront landscape rivers.
Intelligent Automatic Control :Equipped with PLC control cabinet, it supports automatic opening/closing linked with water level and remote unattended operation.
Strong Span Adaptability : The width of single panel is customizable, and combined layout fits both wide and narrow rivers with high universality.


Low-cost & Simple Operation & Maintenance :Key components are exposed for easy inspection with low wear, requiring less daily maintenance work than traditional sluices and dams.
Passage for Small Vessels :No protruding obstacles on the water surface after full collapse, allowing passage of small fishing boats and sightseeing vessels.
Rapid Emergency Flood Control :All panels can be fully laid down quickly during heavy rain and flood to drain stored water in a short time and improve flood drainage capacity.
