AI Technical Summary
Open-pit mine slopes suffer severe environmental damage after mining. Traditional ecological restoration methods are ineffective, vegetation roots are unstable, and existing plant protection devices lack clamping and fixing functions, making vegetation prone to falling over. Repeated construction is costly and not conducive to ecological environment restoration.
Design an open-pit mine slope protection device that uses an arc-shaped frame and an arc-shaped frame combination to clamp and fix plants through clamping cavities and clamping plates. Combined with fasteners and ground-insertion cylinders, the plants are firmly fixed in the soil, thus achieving plant stability. The device is fixed by using hinged support plates and hinged shafts for connection and by inserting ground-insertion cylinders into the soil.
This achieved stable fixation of vegetation, improved the ecological restoration effect, reduced the cost of repeated construction, and enhanced the transformation effect of the mining area's ecological environment.

Technical Field
[0001] This utility model relates to the field of slope protection technology, specifically to a slope protection device for open-pit mines. Background Technology
[0002] After being exposed to wind and rain, the slopes of the former open-pit mine are prone to landslides, which can easily lead to large-scale landslides and pose a great threat to the lives of workers. In severe cases, they can even threaten the residents living below the mine.
[0003] After mining, the overall environment is severely damaged. In the ecological restoration and management of mines, the traditional ecological revegetation involves direct vegetation spraying or filling. However, due to the complex geological environment of mines, the uneven ground with many slopes, serious soil pollution, and abundant sand and gravel, the soil structure is unstable. The roots of the planted vegetation are not stable and are easily damaged, resulting in poor revegetation effect. Repeated construction is costly and not conducive to the transformation of the ecological environment of the mining area. However, the existing plant protection device structure does not have the function of clamping and fixing, and the vegetation is easy to fall over, which cannot meet the needs of use. Therefore, it is necessary to improve the existing technology. Utility Model Content
