Description

Technical Field

[0001] This utility model relates to the field of road protection technology, and in particular to an ecological slope protection structure. Background Technology

[0002] Common slope protection measures aim to limit weathering and erosion of the slope's rock and soil, prevent rockfalls, and control the movement of falling rocks within a certain range. Common slope protection methods include mortar or rammed earth finishing, shotcreting, sprayed concrete, masonry retaining walls, anchored shotcrete slope protection, and anchored shotcrete mesh slope protection. These measures are primarily used to protect against weathering and erosion of rock on excavated slopes, as well as minor rockfalls.

[0003] Traditional engineering slope protection methods often prioritize strength and effectiveness, damaging the natural ecosystem and resulting in poor aesthetics. Furthermore, over time, concrete and masonry surfaces weather, age, and can even deteriorate, leading to high remediation costs. Therefore, a more common approach is to combine engineering and vegetation protection, planting plant communities between concrete retaining walls to stabilize the slope and conserve soil. This combination of plant and engineering measures leverages the advantages of both to effectively resolve the conflict between slope protection and ecological damage, ensuring slope stability while enabling rapid vegetation restoration and achieving harmonious coexistence between human activities and the natural environment.

[0004] However, traditional ecological slope protection structures are unsuitable for mountainous areas with high rainfall. These areas often experience frequent and heavy rainfall, and are prone to geological disasters such as flash floods and mudslides. Traditional slope protection structures are easily eroded by prolonged rainwater runoff, leading to soil loss and further damage to the ecological protective layer. Furthermore, in the event of flash floods, water flowing down the slope can directly erode the roadbed below, potentially causing road surface damage and affecting vehicle traffic. Therefore, a more suitable ecological slope protection structure is needed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an ecological slope protection structure, which solves the problems of soil erosion, damage to the ecological protection layer, and road surface damage caused by floods in areas with high rainfall.

[0006] According to an embodiment of this utility model, an ecological slope protection structure is provided, wherein the slope protection structure is set on the mountainside corresponding to one side of a road, and a drainage ditch is provided between the slope protection structure and the road. The structure includes a plurality of buffer troughs arranged sequentially from top to bottom along the slope of the mountain. The buffer troughs are horizontally extending channels with their interiors recessed downwards. Adjacent buffer troughs are arranged sequentially with their ends connected. The interior of the buffer troughs is provided sequentially from top to bottom with an ecological layer, a soil layer, and a gravel layer. The gravel layer is set close to the surface of the mountain, the soil layer covers the surface of the gravel layer, and the ecological layer consists of plants planted on the surface of the soil layer. The bottom buffer trough is set at the edge of the drainage ditch.

[0007] Furthermore, the cross-section of the buffer trough along the direction perpendicular to the road is an arc-shaped structure, and the lowest point of its internal channel is lower than the connection position between the lower edge and the top of the adjacent buffer trough, thereby forming a water storage section.

[0008] Furthermore, a baffle extending outward is provided at the lower edge of the buffer groove, the baffle being parallel to the tangent direction of the bottom edge of the buffer groove, and perforated water-permeable holes are provided on the baffle.

[0009] Furthermore, a drainage ditch is buried inside the mountain below the buffer ditch. The drainage ditch is inclined and its bottom end is connected to a drainage ditch. A vertical connecting groove is provided at the bottom of the buffer ditch to connect to the drainage ditch.

[0010] Furthermore, the crushed stone layer extends into the connecting groove, thereby completely filling the connecting groove. A permeable partition plate is provided at the bottom of the connecting groove, thereby blocking the crushed stone layer above the drainage groove.

[0011] Furthermore, the number of buffer grooves set on the slope of the mountain is 4-6.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention features a multi-layered buffer trough structure, which forms multiple buffer structures on the slope of the mountain. As rainwater flows down the mountain, it is continuously blocked, thereby reducing the flow velocity of the rainwater and mitigating its damage to the soil and vegetation in the slope protection structure, thus maintaining the effectiveness of the ecological layer. At the same time, it also prevents floodwater from flowing directly down the mountain and impacting the road surface, and avoids the high-speed impact of rocks and other debris carried by the floodwater, which would cause damage to the road surface, thus maintaining the integrity of the road surface structure.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown in the figure, this utility model embodiment proposes an ecological slope protection structure, which is set on the mountain 1 on one side of the road 2, and a drainage ditch 3 is provided between the slope protection structure and the road 2.

[0019] The slope protection structure in this embodiment includes several buffer troughs 4 arranged sequentially from top to bottom along the slope of the mountain 1. The number of buffer troughs 4 arranged on the slope of the mountain 1 is 4-6, and 4 are preferred in this embodiment. The buffer troughs 4 are horizontally extending channels with downward-facing depressions. Adjacent buffer troughs 4 are arranged sequentially with their ends connected. When rainwater flows down the mountain 1, it is continuously blocked, thereby reducing the flow velocity of rainwater and mitigating its damage to the soil and ecological plants in the slope protection structure, thus maintaining the effectiveness of the ecological layer. At the same time, it also prevents floodwater from directly impacting the road surface of the road 2 by flowing down the mountain 1, and avoids high-speed impacts from rocks and other debris carried by floodwater, which could damage the road surface and maintain the integrity of the road surface structure.

[0020] like Figure 2 As shown, the buffer trough 4 contains, from top to bottom, an ecological layer 41, a soil layer 42, and a gravel layer 43. The gravel layer 43 is set in close contact with the surface of the hill 1, the soil layer 42 covers the surface of the gravel layer 43, and the ecological layer 41 consists of plants planted on the surface of the soil layer 42. The bottom buffer trough 4 is located at the edge of the drainage ditch 3. In this way, the gravel layer 43 makes the soil layer 42 more stable and less prone to being washed away by rainwater, while also reinforcing the soil inside the hill 1.

[0021] In this embodiment, a baffle 5 extending outward is provided at the lower edge of the buffer trough 4. The baffle 5 is parallel to the tangent direction of the bottom edge of the buffer trough 4, and has perforated drainage holes. This allows the baffle 5 to partially block impurities such as stones mixed in with the rainwater flowing down the buffer trough 4, preventing them from flying outward and falling onto the surface of the road 2, thus reducing damage to the road 2. Simultaneously, it further buffers the water flow through the buffer trough 4, reducing its flow velocity and minimizing the impact on the subsequent ecological layer 41 inside the buffer trough 4.

[0022] Preferably, a drainage ditch 6 is buried inside the hillside 1 below the buffer ditch 4. The drainage ditch 6 is inclined, and its bottom end connects to the drainage ditch 3. A vertical connecting ditch 7 is provided at the bottom of the buffer ditch 4, connecting to the drainage ditch 6. In this way, rainwater deposited inside the buffer ditch 4 can be drained away from below, preventing a large amount of water from remaining in the soil layer 42 and the gravel layer 43, which could affect the stability of the internal structure due to long-term soaking. Correspondingly, the gravel layer 43 extends into the connecting ditch 7, completely filling it. A permeable partition plate 71 is provided at the bottom of the connecting ditch 7, thus blocking the gravel layer 43 above the drainage ditch 6. This prevents the soil layer 42 from passing through the connecting layer into the drainage ditch 6 and being lost, maintaining the growth foundation for plants in the upper ecological layer 41.

[0023] Furthermore, in this embodiment, the buffer trough 4 has a circular arc-shaped cross-section along the direction perpendicular to the road 2. The lowest point of its internal channel is lower than the connection point between the lower edge and the top of the adjacent buffer trough 4, thus forming a water storage section. The water storage section allows water to flow more effectively into the drainage outlet below, thereby achieving a diversion effect, reducing the surface water volume of the mountain 1, and preventing flash floods.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
