Description

Technical Field

[0001] The present application relates to the technical field of slope protection, and in particular to a road slope protection structure with high stability. Background Art

[0002] Slope protection refers to the general term for various paving and planting on the slope surface to prevent the slope from being eroded. Road slope protection is a series of measures taken to protect the stability of the roadbed slope, prevent soil erosion, beautify the environment and adapt to changes in the natural environment. After searching, the patent document with the authorization announcement number CN216839510U announced a slope protection structure for road engineering, including: a foundation, a slope structure, a slope planting drainage structure, and a drainage structure, wherein the slope structure includes: a slope body, a partition plate fixedly installed on the inclined surface of the slope body, a support plate partially horizontally embedded in the slope body, a plurality of drainage holes opened on the exposed part of the support plate, an inner lining plate horizontally embedded in the slope body and located between two support plates with a smaller upper and lower distance, and a grouting pipe horizontally inserted into the inner lining plate. The embedding force generated by the inner lining plate embedded between the two support plates squeezes the surrounding soil or rock, the grouting pipe anchors the inner lining plate in the slope body, and the cementitious slurry is injected through the grouting pipe to further reinforce the slope body, thereby improving the stability of the slope.

[0003] In actual use, it was found that the above-mentioned related schemes still have at least the following shortcomings: since the reinforced slope is an inclined slope, although a flood discharge channel is set on the slope, when the slope is relatively long, in heavy rain weather, a large amount of rainwater will not pass through the flood discharge channel and flow rapidly downward from the top of the slope, which will increase the impact force on the slope and the impact force on the planting soil bags, and reduce the stability of the slope. Therefore, we propose a road slope protection structure with high stability to solve the above problems. Utility Model Content
