[0001] The present invention relates to the technical field of slope protection, and in particular to a slope ecological restoration and slope protection device and method. Background Art

[0002] With the rapid development of infrastructure construction, the problem of uncoordinated ecological environment development has arisen. Due to the large number of mountains in my country, a large number of slopes are often generated during engineering construction, such as mountain road slopes, reservoir bank and riverside road slopes, etc. In order to prevent the slopes from being washed away by rainwater and causing landslides and collapses, it is necessary to take protective measures for the slopes.

[0003] In order to solve the problem of "the slope will be washed away by rain", the Chinese patent with the publication number CN116971403A discloses a slope ecological restoration and slope protection device, including: a fixing component, the fixing component includes a plurality of first frames, the plurality of first frames are detachably connected, the first frames are located on the upper surface of the slope, the first frames are fixedly connected to the slope through fixing rods, and the fixing rods are inserted into the slope; a planting component, the planting component includes a plurality of planting boards, the planting boards are provided with a plurality of seed slots, the seed slots are filled with grass seed bags, the planting boards are filled with soil, and the planting boards are detachably connected to the first frames; a drainage component, the drainage component includes a drainage trough, the drainage trough is provided between two rows of first frames, a water retainer is provided on the first frame, and the water retainer is connected to the drainage trough. Although the existing technical problems have been solved, the following problems still exist: In this technical solution, when it rains, the diversion trough can block part of the rainwater, reducing the scouring effect of rainwater on the soil in the first space, and the rainwater flows out from the water flow holes along the diversion trough. However, if the diversion trough is set too densely, it will block the lighting of the soil vegetation under the diversion trough and affect its growth. If the diversion trough is set too sparsely, the rainwater blocked is limited, and the effect of preventing rainwater scouring cannot be achieved. Therefore, corresponding improvements are made to this problem. Summary of the invention
