Construction method and stone ridges capable of preventing erosion of sloping agricultural road

Abstract

The invention relates to a construction method and stone ridges capable of preventing erosion of a sloping agricultural road and belongs to the technical field of road soil erosion control. The slopegradient of the sloping agricultural road is surveyed, ditches are excavated in the sloping agricultural road and filled with stone ridges or prefabricated stone ridges are directly arranged, road undercutting is prevented under the protection and reinforcing actions of the stone ridges, sediment is intercepted and stored on the upstream face of the stone ridges, runoff flow speed is retarded, anddrop energy dissipation is formed on the downstream face of the stone ridges.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of road soil erosion, and in particular relates to a construction method and a stone ridge for preventing erosion of agricultural roads on sloping land. Background technique [0002] For soil-based agricultural roads on sloping land, there are generally no drainage facilities on both sides, and they are easily rolled by agricultural machinery to form ruts, making sloping agricultural roads a place where runoff gathers, and the intensity of road surface erosion is intensified, resulting in erosion ditches, which not only affect normal agricultural machinery Passing through, and encroaching on the farmland on both sides. [0003] At the end of the 20th century, the research work on the erosion of sloping agricultural roads began at home and abroad, and the research focused on the mechanism of road erosion. There were relatively few studies on how to prevent and control the erosion of ...

[0002] For soil-based agricultural roads on sloping land, there are generally no drainage facilities on both sides, and they are easily rolled by agricultural machinery to form ruts, making sloping agricultural roads a place where runoff gathers, and the intensity of road surface erosion is intensified, resulting in erosion ditches, which not only affect normal agricultural machinery Passing through, and encroaching on the farmland on both sides

[0003] At the end of the 20th century, the research work on the erosion of sloping agricultural roads began at home and abroad, and the research focused on the mechanism of road erosion. There were relatively few studies on how to prevent and control the erosion of sloping agricultural roads. According to the data, Liu Yaojun et al. studied the effects of three vegetation restoration models on The impact of soil road slope erosion, Liu Xueying et al. studied the anti-corrosion benefits of hillside plant roads in the loess hilly area, and Zheng Shiqing et al. Discussing the prevention and control of road erosion from the perspective of plant measures, the technical promotion is not strong. In areas with large catchment areas, due to the large amount of water coming in from the field roads, the water flow speed is fast, and the scouring force is strong, it is difficult to prevent and control road surface erosion.

But this invention can't be applicable to the erosion prevention and control of sloping agricultural roads
