The working principle of the hydraulic flip gate in a hydraulic steel dam: The dam has a large span, a simple structure, reliable support, and is easy to manufacture; the hydraulic system operates sensitively and can be controlled by a buoy switch, achieving automated operation and unmanned management; the dam can fundamentally maintain the original riverbed, allowing for the free flow of floodwater, upstream sediment, cobblestones, and floating debris without obstructing water flow.

Compared to traditional sluices and similar rubber dams, it boasts a higher flow capacity and greater discharge volume. It is particularly suitable for rivers with abundant sand, stones, trees, bamboo, and in cold regions where rubber dams are not ideal for construction. It can also freely adjust the dam height and overflow, controlling the upstream water level and discharge volume. Construction is simple and the project timeline is short. Compared to traditional sluices, it reduces the need for pier blocks, numerous metal structural components, and gate opening and closing equipment, resulting in less concrete work and significant cost savings.

The project's durability is longer than that of rubber dams, as it only requires normal protection of the weir face structure and hydraulic system. It is a low-head water-retaining structure, widely used in hydraulic irrigation, hydropower generation, and urban beautification. Particularly in the development of urban river step-pools, it can create expansive water surfaces, enhance cityscape corridors, and easily form waterfall landscapes on the dam body, effectively improving the ecological and cultural environment and advancing the social environment grade of the city.
