[0029] In the related art, the slope treatment usually adopts retaining wall, gravity dam and other structures for reinforcement, which can play a certain effect in the short term, but over time, the surface layer of soil is still easy to be affected by natural factors such as water force and wind force, causing the structure of soil to be loose and the adhesion to be poor, so it cannot fundamentally improve the structure of soil and the ecological environment.
[0030] Based on this, the embodiment of the present application provides a high and steep slope ecological restoration structure to solve the above technical problems. The high and steep slope ecological restoration structure provided by the embodiment of the present application is introduced below.

The retaining wall 11 can adopt a prefabricated structural member. Specifically, the retaining wall 11 can be a reinforced concrete prefabricated member, so that the retaining wall 11 can be mass-produced in the factory to reduce the on-site construction time and labor intensity.
[0033] The retaining wall 11 is in an upright state, a through hole penetrating along the thickness direction of the retaining wall 11 is arranged on the retaining wall 11, a reinforcing wall body 14 is arranged on the front side of the retaining wall 11, the reinforcing wall body 14 is in an integral structure with the retaining wall 11, the reinforcing wall body 14 extends longitudinally, and the bottom surface of the reinforcing wall body 14 is flush with the bottom surface of the retaining wall 11. The reinforcing wall body 14 is beneficial to enhance the stability of the structure of the retaining wall 11, improve the bearing capacity of the retaining wall 11, and make the retaining wall 11 more stable. In addition, the thickness of the reinforcing wall body 14 can be equal to or slightly smaller than the thickness of the retaining wall 11, the width of the reinforcing wall body 14 is smaller than the retaining wall 11, and the through hole can penetrate the reinforcing wall body 14 and the retaining wall 11 in turn.
[0034] The anchor rod 13 is anchored with the slope by penetrating the reinforcing wall body 14 and the retaining wall 11 through the through hole. The anchor rod 13 can be arranged between 6m-10m, and the anchoring depth of the anchor rod 13 in the slope surface can be arranged between 4m-8m, so as to improve the anchoring strength of the anchor rod 13, and further improve the stability of the retaining wall 11.
[0035] The concrete filling layer 12 is arranged between the retaining wall 11 and the slope surface, and the top surface of the concrete filling layer 12 is flush with the upper edge of the retaining wall 11. Specifically, the concrete filling layer 12 can be arranged by on-site pouring.
