Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a triple ecological protection structure for a slope. Background Art

[0002] Slope refers to any geological body on the ground surface that has an inclined surface facing the air. It is a kind of landform widely distributed on the surface. In road engineering, slope is an important part of road construction, and often serves as an auxiliary structure to maintain the normal operation of the road. Road slope protection mainly uses masonry or concrete to form a certain structure to protect the slope. Due to its convenient material acquisition and relatively mature design and construction technology, it is called a more common protection method. Triple ecological protection is a slope protection technology that integrates safety protection and ecological restoration. It protects the slope by combining physical protection, anti-corrosion protection, and vegetation ecological restoration protection.

[0003] The patent number CN214497551 U in the prior art discloses a slope ecological protection structure, including a slope, which has a slope surface; a plurality of anchor rods are arranged on the slope surface, one end of the anchor rod is embedded in the slope, and the other end is bent to form a bending portion, so that the anchor rod is L-shaped as a whole; a retaining plate is arranged on each anchor rod, the retaining plate is located between the slope surface and the bending portion, and the length direction of the retaining plate is arranged along the inclination direction of the slope; planting soil is laid on the slope surface, a metal mesh is laid on the upper surface of the planting soil, and the metal mesh corresponding to the bending portion of the anchor rod passes through the bending portion of the anchor rod, so that the metal mesh is located in the bending portion of the anchor rod; a seedling matrix is ​​laid on the upper side of the metal mesh, and a non-woven fabric is also laid on the upper side of the seedling matrix. The utility model can increase the thickness of the planting soil of the slope, provide a good soil environment for the growth of plants on the slope, thereby improving the survival rate of plants on the slope, and further improving the ecological effect of the slope.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] (1) The existing protective structure prevents the slope soil from being eroded by setting a retaining plate inside the slope. However, the retaining plate cannot divert rainwater from the slope during heavy rain. Rainwater easily forms runoff on the slope, causing the seedling medium and even the slope soil to be eroded into deep gullies. Over time, the slope soil vegetation will be severely damaged.

[0006] (2) The existing protective structure has a low utilization rate of rainwater and does not have the function of collecting rainwater. In dry weather, it is impossible to irrigate the slope ecological vegetation, which easily leads to the drought and water shortage of the slope ecological vegetation and the death;

[0007] (3) The existing protective structure provides a good soil environment for the later growth of slope plants by laying planting soil on the slope, laying a metal mesh on the upper surface of the planting soil, and laying a seedling medium on the upper side of the metal mesh. However, due to the low nutrition and microbial activity of the seedling medium (planting soil), and the limitations of the slope site conditions and the influence of rainfall erosion, the nutrients in the seedling medium will gradually be lost and become increasingly barren, resulting in a problem that the greening effect is good in the short term, but the transplanted plants will find it difficult to grow healthily over time, and the greening effect is difficult to maintain.
