Description

Technical Field

[0001] This utility model belongs to the field of slope protection technology, and in particular relates to a slope protection structure for highway engineering. Background Technology

[0002] Effectively prevents rainwater erosion of slopes, protecting the roadbed slope surface. Reduces the negative impact of temperature and humidity changes on slopes, preventing weathering, erosion, and other evolutionary processes. Reinforces unstable slopes, reduces the risk of collapse, and ensures the safety of the surrounding environment and personnel. Prevents slope debris from rolling down slopes and damaging infrastructure such as highways and railways. Slope protection projects can also beautify the roadbed and harmonize with the natural environment, enhancing the overall landscape effect.

[0003] Comparing with Chinese Patent No. CN211713989U, a slope protection structure for highway engineering is disclosed, including a foundation, a roadbed set on the foundation, and a slope body located on one side of the roadbed. The slope body is set on the foundation, and a reinforcement layer is laid on the surface of the slope body. Several fasteners are inserted through the reinforcement layer, and after passing through the reinforcement layer, the fasteners are fixedly connected to the slope body. Each fastener is equipped with a connector, and adjacent fasteners are connected through the connector. This structure improves the stability of the slope body.

[0004] However, the aforementioned patent only addresses the supporting function of the reinforcement layer. If the main slope expands under gravity and pushes the reinforcement layer outward, there will be no resistance, which seriously affects stability and reliability. Therefore, a new device needs to be designed. Utility Model Content
