[0014] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0015] An ecological slope protection structure for watershed management of a water conservancy project comprises a plurality of stacked ecological boxes 1, wherein the cross section of the ecological boxes 1 is an isosceles trapezoid and a rectangle connected to each other, the large base of the isosceles trapezoid is in contact with the long side of the rectangle, and the small base of the isosceles trapezoid is located on the water-facing side. The water-facing sides of the plurality of ecological boxes 1 stacked on the same layer are flush, and the stacked multi-layer ecological boxes 1 are set back layer by layer from bottom to top, that is, the water-facing side of the ecological box 1 of the upper layer is located behind the water-facing side of the ecological box 1 of the lower layer, and the upper and lower adjacent ecological boxes are arranged so that the water-facing side of the ecological box 1 of the upper layer is located behind the water-facing side of the ecological box 1 of the lower layer. The eco-boxes 1 are staggered with each other, that is, the center lines of the adjacent upper eco-boxes 1 are aligned with the gap between the two lower eco-boxes 1. The combination of retreat and staggered layout makes the water-facing surface of the slope uneven, which can buffer the impact of water flow. Each of the eco-boxes 1 is a trough box structure with an open top. The interior of the eco-box 1 is filled with soil for planting vegetation. A stabilizing frame 11 is fixed on the rear and outer side walls of each eco-box 1. The stabilizing frame 11 is connected to the existing river slope to ensure the stable position of the eco-box 1.

[0016] Two stabilizing frames 11 are fixedly installed on the rear outer wall of each of the eco-boxes 1. The two stabilizing frames 11 are arranged along the diagonal direction on the rear outer wall of the eco-box 1. The suspended end of each of the stabilizing frames 11 pointing to the rear is set as a rectangular frame. The rectangular frame can be fixedly connected to the existing slope of the river channel through other connecting parts. After the fixed connection is completed, the space between the eco-box 1 and the existing slope of the river channel is filled with soil and vegetation is planted. The roots of the vegetation will be interspersed in the soil and between the stabilizing frames 11, thereby stabilizing and reinforcing the eco-box 1.

[0017] Two limiting protrusions 12 are protruding from the outer bottom surface of each of the eco-boxes 1. The two limiting protrusions 12 are centrally arranged and symmetrically arranged about the center line of the bottom plate of the eco-box 1. The distance between the two limiting protrusions 12 is twice the thickness of the wall of the eco-box 1. When multiple eco-boxes 1 are stacked, the two limiting protrusions 12 at the bottom of the upper eco-box 1 are clamped on both sides of the wall of the two adjacent eco-boxes 1 in the lower layer. While ensuring the stability of the upper eco-box 1, the distance between the lower eco-boxes 1 can be prevented from expanding, which can effectively ensure that the ecological slope formed by the stacking maintains structural stability.

[0018] A plurality of drainage holes 13 are provided on the bottom plate of each eco-box 1 to facilitate the drainage of water flowing into the eco-box 1 due to the impact of the water flow in the basin.

[0019] Ecological box 1 is made of cement material.

[0020] Working principle: When the slope protection structure is applied, it is stacked from bottom to top, and multiple eco-boxes 1 on the same layer are close to each other. The stabilizing frame 11 is fixedly connected to the existing slope using connecting parts such as iron chains and rivets, and the gap between the eco-box 1 and the existing slope is backfilled with soil. The limiting protrusions 12 of the upper eco-box 1 are clamped on both sides of the box walls of the two adjacent eco-boxes 1 in the lower layer to clamp the lower eco-box 1. Each eco-box 1 is backfilled with soil and vegetation is planted. Seedlings or sowing can be selected according to specific circumstances. The rich root system produced by the growth of vegetation will stabilize the soil and prevent it from being washed away by water. At the same time, the growth of vegetation can beautify the environment on both sides.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
