1. Foundation Eco-Frame: This frame is primarily used to protect riverbanks, prevent soil erosion and landslides, while also promoting plant growth and enhancing the stability of the ecosystem.

2. Fish Nest Landscape Channel Frame: This frame design focuses on creating a river ecosystem with both aesthetic appeal and ecological benefits, where the fish nest design provides an ideal environment for fish growth and reproduction.

3. Concrete Grassing Eco-Block Frames: These frames are primarily used for water conservation and prevention of runoff, while also promoting plant growth and reducing water pollution and soil erosion.

4. Step-waterway Frame: This frame is primarily used to prevent rapid water flow, mitigate the impact force of the water flow, maintain the stability of the aquatic ecological environment, and also effectively regulate water volume and ensure farmland irrigation.
