Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a high-strength flexible reinforced mesh pad suitable for slopes. Background Art

[0002] In the construction of railways, highways, hydropower, mining and other projects, large amounts of slope excavation are often required. Slope excavation destroys the original vegetation cover, resulting in a large amount of secondary bare land and severe soil erosion, exacerbating the degradation of the ecosystem. Therefore, how to quickly restore the ecological environment of the excavated slopes and achieve vegetation protection on the slopes is a topic that urgently needs to be studied and solved. When using engineering measures to protect the slopes, the vegetation lacks an environment for growth, and the damaged vegetation is difficult to recover quickly. Moreover, over time, the concrete surface and the mortar-laid stone surface will weather, age, and even cause damage, resulting in high costs for subsequent remediation. In contrast, vegetation slope protection is a new technology that uses the principle of vegetation retaining water and consolidating soil to stabilize rock and soil slopes while beautifying the ecological environment. It can effectively achieve ecological vegetation restoration on the slopes.

[0003] Currently, vegetation protection technologies for soil or soil-rock mixed slopes include turf paving, vegetation belts, hydraulic seeding, three-dimensional vegetation nets, and vetiver hedges. However, actual project conditions vary greatly. For small, poor-quality soil or soil-rock mixed slopes, soil suitable for vegetation growth is often lacking or the soil is poor, fertile, and dry, making it difficult for construction machinery to access. Furthermore, turf paving and vetiver hedges are difficult to maintain and manage, and cannot address the problem of poor soil quality. Vegetation belts and three-dimensional vegetation nets also have the problem of being unable to improve poor soil quality.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a high-strength flexible reinforced mesh pad suitable for slopes. Utility Model Content

[0033] Specifically, this embodiment discloses a high-strength, flexible reinforced mesh mat suitable for use in construction environments such as slopes.
