A water permeable hole is provided at one end of the drainage pipe, and a permeable geotextile is provided on the outside of the water permeable hole; soil is provided on the lower wall of the retaining block, and the soil is buried to the platform on the upper part of the retaining block. The utility model not only has high stability, but also facilitates water permeability.

[0004] The drainage pipe of the device can only drain rainwater from a small area inside the soil (such as the attached Figure 3 As shown in the figure, due to the different permeabilities of soil and retaining wall, soil usually has a higher permeability, while the permeability of retaining wall is very low. When rainfall or snowmelt penetrates into the soil, part of the water will penetrate to the bottom of the retaining wall, while the other part of the water will be blocked by the retaining wall, causing the water to accumulate at the connection between the retaining wall and the soil. However, the device cannot well discharge the rainwater accumulated at the connection between the retaining wall and the soil to reduce the erosion of the retaining wall and the soil by the accumulated water. Therefore, a retaining wall structure for soil and water conservation in mine waste rock dump is provided. Utility Model Content
