Composite anti-slip retaining structure

The utility model discloses a composite anti-skidding retaining structure which is composed of anti-skidding piles and a grouting reinforcing body, the grouting reinforcing body is arranged in an anchoring section stratum below a sliding layer, the grouting reinforcing body is formed by injecting cement paste or cement mortar into rock soil to be solidified, and the grouting reinforcing body is acuboid or a cylinder or an ellipsoid. The anti-sliding pile is composed of an upper anti-sliding section and a lower anchoring section, the anchoring section is fixedly embedded in the grouting reinforcing body, and the anti-sliding section is arranged in the sliding layer. The device is simple in structure and low in cost; the weight and the stress area of the grouting reinforcement body are remarkably increased, the deformation resistance and the stress state of the anti-sliding section and the anchoring section are greatly improved, the anti-sliding capacity of the anti-sliding pile is greatly enhanced under the sa
