The invention discloses a slope protection structure being answerable for water and
soil loss. The slope protection structure comprises a slope protection body, wherein a plurality of stages of stepsare arranged on the slope protection body, a triangular groove belt is arranged in each step, a rainwater filtering device is arranged in each triangular groove belt, each rainwater filtering device comprises two
punching plates, a multi-stage covering layer and a drainage channel, wherein the two
punching plates are tightly attached to the two sides of the triangular groove belt correspondingly,the multi-stage covering layer is arranged between the two
punching plates at one time from top to bottom, the drainage channel is arranged below the multi-stage covering layer, and the drainage channel communicates with a slope surface drainage
system. According to the slope protection structure, the rainwater filtering device is arranged on each stage of the step, and stepped interception of
precipitation is achieved; when the
precipitation amount is small,
precipitation can be naturally permeated into the slope surface soil through the punching plates; when the precipitation amount is large, a small amount of precipitation directly penetrates into the slope surface soil, and the remaining precipitation is gathered to the slope surface drainage
system through the drainage channels to bedrained; and precipitation is prevented from directly flushing the slope surface, and the water and
soil loss of the slope surface is reduced.
