Problems solved by technology

However, for seriously degraded slopes such as slag stockpiles and gravel stockpiles in rainy areas, especially for steeper slopes, how to make the sprayed matrix anti-scouring is the key to whether plants can get The biggest problem of better growth and root system fully growing and penetrating into the original soil layer to achieve better protection effect, the original idea of ​​increasing nutrition to increase plant growth obviously cannot solve the above problems
[0005] To sum up, the existing technology cannot fundamentally solve the problem of slope improvement and greening with serious degradation such as slag storage yards and gravel storage yards in remote and rainy areas

Abstract

The invention provides an anti-scouring fiber spraying matrix and its application in the process of slope ecological restoration. The spraying matrix includes heat-treated wood fiber and artificial interlocking fiber, and the mass ratio of heat-treated wood fiber and artificial interlocking fiber is 56‑61:21‑25. The total mass of the heat-treated wood fiber and the artificial interlocking fiber accounts for 80-84% of the total amount of the sprayed matrix. Said application: the spraying thickness of the scour-resistant fiber spraying matrix is ​​controlled at 3-6mm, and the porosity of the spraying matrix after spraying is 75-80%. When the scour-resistant fiber spraying matrix is ​​applied in the process of slope ecological restoration, the amount of soil loss is reduced by more than 90%; the plant survival rate is increased to more than 90%.

Description

technical field [0001] The invention relates to a slope protection method, in particular to an anti-scouring fiber spraying matrix and its application in the process of ecological restoration of a slope, and belongs to the technical field of environmental protection. Background technique [0002] In remote areas with poor soil resources, such as Xinjiang, Tibet or mountainous areas, due to poor soil conditions and inconvenient soil extraction, it is impossible to use the traditional method of covering soil for slope protection. If the traditional covering soil technology is applied in areas with harsh natural conditions and frequent heavy rains, there will be problems that the rainwater will quickly wash away the slope and the rainwater should not be retained, making it difficult for the existing technology to effectively protect the slope. [0003] Therefore, it is very difficult to restore seriously degraded slopes, such as slag storage yards and gravel storage yards. The...
