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.
