Adjacent means close in position.
[0024] The retaining wall is mainly applied to bare mountains, and can prevent natural disasters such as landslides of the bare mountains by inhibiting development of landslides of the bare mountains. The bare mountain generally comprises a rock layer 10 and a soil layer 20 arranged on the surface of the rock layer 10; the transverse direction of the slope surface of the soil layer 20 is perpendicular to the down-slope direction of the slope surface of the soil layer 20, and the inclination direction of the soil layer 20 generally refers to the down-slope direction of the slope surface of the soil layer 20. The retaining wall blocks the soil layer 20 of the bare mountain by arranging retaining wall mechanisms 30 and foot stabilizers 50. Since the retaining wall mechanisms 30 are at least two and are spaced apart along the transverse direction of the slope surface of the soil layer 20, and the retaining wall mechanisms 30 comprise at least two arc-shaped plates 310 spaced apart along the inclination direction of the soil layer, the retaining wall mechanisms 30 arranged can not only effectively block soil and inhibit development of landslides of the bare mountain, but also improve the stability of the retaining wall mechanisms 30 due to the high pressure-bearing capacity of the arc-shaped plates 310 in the arched structure. Meanwhile, the arc-shaped plates 310 are connected together by connecting structures, which ensures the integrity of the retaining wall mechanisms 30 and facilitates force bearing together, thereby further improving the pressure-bearing capacity of the retaining wall mechanisms 30. In addition, the drainage mechanisms 40 are arranged, the end of the drainage groove formed between the connecting plates 320 and the arc-shaped plates 310 is communicated with the adjacent drainage mechanisms 40, rainwater, mountain seepage and other water bodies are guided into the drainage mechanisms 40, thereby being discharged, and the development of landslides of the bare mountain is further inhibited, and the risk of landslides of the bare mountain is reduced.

[0027] Preferably, as shown in Figure 5 As shown, the water inlet 420 is provided with a first filter screen 450, and the through hole 430 is provided with a second filter screen 460. By providing the first filter screen 450 and the second filter screen 460, the soil can be prevented from being carried away during drainage, the soil loss is ensured, the vegetation growth is facilitated to cover the soil, and the soil fixation capacity is improved. The first filter screen 450 and the second filter screen 460 can be various, and are preferably fiber filter screens with corrosion resistance and long service life.
