Description

Technical Field

[0001] This application relates to the field of slope treatment technology, and in particular to an ecological slope protection structure with directional flow guidance. Background Technology

[0002] Ecological slope protection refers to ecological restoration and protection measures implemented during engineering construction or land use to protect the land's ecological environment and prevent natural disasters (such as landslides and debris flows). It typically employs reinforcement measures, such as reinforcing nets and retaining walls, to improve slope stability and bearing capacity, preventing landslides and instability. Simultaneously, planting vegetation on the slope, especially plants with well-developed root systems and slope-protecting properties, such as herbaceous plants, shrubs, and trees, increases the slope's resistance to erosion and stabilizes the soil.

[0003] During the high-water season, with heavy rainfall, large-scale runoff forms on slopes, resulting in significant short-term flow rates. If tunnels, culverts, caverns, or protected historical buildings exist beneath the slope, the large flow of runoff can easily cause these structures or entrances to collapse. Therefore, a reasonable drainage and infiltration system needs to be designed for the slope to prevent water accumulation from affecting slope stability and underlying facilities, while also reducing the risk of soil liquefaction. However, current technology generally lacks the capacity to regulate and divert runoff during both dry and high-water seasons. Large-flow slope runoff exerts a strong impact on the slope surface, causing soil erosion. For important facilities beneath the slope, a common practice is to cover the entrances before the high-water season or before heavy rainfall to prevent erosion or backflow. This requires manual operation before rainfall, which is not only cumbersome but also aesthetically unappealing.

[0004] In response to the above situation, there is an urgent need for a slope protection structure that can stabilize the surface soil structure of slopes, facilitate ecological planting, and regulate and divert slope runoff during both dry and wet seasons. Through ecological restoration and protection measures, the land's ecological environment can be protected, the occurrence of natural disasters reduced, and safety and sustainable development ensured. Utility Model Content

[0005] To address the aforementioned problems, this application provides an ecological slope protection structure with directional flow guidance.

[0006] The ecological slope protection structure with directional flow guidance provided in this application adopts the following technical solution: An ecological slope protection structure with directional flow guidance includes: multiple sets of frame slope protection units and a main flow channel set at the bottom of the slope; the multiple sets of frame slope protection units include at least four different structures, each frame slope protection unit is composed of a polygonal frame and a flow channel; the flow channel is fixed to the corresponding polygonal frame at different angles, and each flow channel connects at least two corners of the polygonal frame; some of the frame slope protection units also have drainage holes at the bottom of the flow channel; among the polygonal frames, the frames used to form the boundary are set as trapezoidal structures, and the length of their short sides is adapted to the side lengths of other polygonal frames used for the main paving of the slope, so as to achieve seamless splicing with each set of frame slope protection units.

[0007] Preferably, the polygonal frame used for the main paving of the slope is a hexagonal frame; the hexagonal frame has a through hole in the middle.

[0008] Preferably, all the guide channels are U-shaped guide channels, and in the guide channels with drainage holes, there are four drainage holes, which are in the form of square through holes.

[0009] Preferably, the frame slope protection units used for the main slope paving are laid flat on the upper surface of the slope soil from bottom to top, and the frame slope protection units used to form the boundary are laid on the top edge and bottom edge of the slope respectively, so that the outer contour of the top and bottom of the slope forms a straight structure.

[0010] Preferably, the laying angle and arrangement order of each set of frame slope protection units are adjusted so that the guide channels on all frame slope protection units are interconnected to form a continuous guide channel, and the end of the guide channel is connected to the total guide channel at the bottom of the slope.

[0011] Preferably, the main diversion channel is located in the area below the facilities at the bottom of the slope.

[0012] In summary, this application includes the following beneficial technical effects: By reinforcing the slope with hexagonal frames, the soil on the slope surface is stabilized, solving the problem of landslides and instability caused by water flow. Simultaneously, vegetation can be planted on the slope to further increase its water retention capacity.

[0013] It can regulate slope runoff under conditions of low and high flow rates during dry and wet seasons. When the flow rate is low, water is drained into the slope through drainage holes. When the flow rate is high, the water is directed to the bottom of the slope through directional drainage, thereby regulating the slope flow, reducing the impact of high flow rates on the slope, and reducing soil erosion.

[0014] Under conditions of high-flow-rate runoff on a slope, the runoff is directed to reduce the impact of the high-flow-rate runoff on important facilities in key locations at the bottom of the slope during high-flow-rate precipitation, thereby protecting these facilities.

[0026] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0027] Example 1 This application discloses an ecological slope protection structure with directional flow guidance. (Refer to...) Figures 1 to 4 It includes multiple sets of frame slope protection units and a main diversion channel (diversion channel E61) set at the bottom of the slope. The specific structure and design are as follows: The multiple sets of frame-type slope protection units include four differentiated structures: frame-type slope protection brick A, frame-type slope protection brick B, frame-type slope protection brick C, and frame-type slope protection brick D; each consists of a polygonal frame and a guide channel. like Figure 1 and Figure 5 As shown, the frame-type slope protection brick A consists of a frame A11, a diversion channel A12, and drainage holes A13. The frame A11 is a hexagonal frame with a diversion channel A12 on its surface. The diversion channel A12 is U-shaped, connecting to the frame A11 on one side and at least two corners of the frame A11, forming an inclined diversion area. When the slope water flow is large, the water can flow along the diversion channel, playing a guiding role and reducing the impact of the water flow on the facilities below the diversion channel on the slope. The bottom of the diversion channel A12 has four drainage holes A13, which are square through holes suitable for small-flow infiltration.

[0028] like Figure 2 and Figure 6 As shown, the frame-type slope protection brick B consists of a frame B21, a flow guide channel B22, and drainage holes B23. The frame B21 is a hexagonal frame with a flow guide channel B22 on its surface. The flow guide channel B22 is U-shaped, connected to the frame B21 on one side, and at least to two corners of the frame B21, forming a straight flow guide area. The bottom of the flow guide channel B22 has four drainage holes B23, which are square through holes and have the same function as drainage holes A13.

[0029] like Figure 3 and Figure 7 As shown, the frame-type slope protection brick C consists of a frame C31, a guide channel C32, and drainage holes C33. The frame C31 is a hexagonal frame with a guide channel C32 at the bottom of its surface. The guide channel C32 is U-shaped and connects to the frame C31 on one side, and at least to two corners of the frame C31. The bottom of the guide channel C32 has four drainage holes C33, which are square through holes and have the same function as drainage holes A13 and B23.

[0030] like Figure 4 and Figure 8 As shown, the frame slope protection brick D: is only frame D51. Frame D51 is a trapezoidal polygonal frame. Its short side length is compatible with the side length of the hexagonal frame of frame A11, frame B21 and frame C31. It can be seamlessly spliced ​​with the other three types of frame slope protection bricks to form the slope boundary.

[0031] The flow channels of the four types of frame slope protection bricks are fixed to the corresponding frames at different angles. By adapting to the flow guidance needs of different areas of the slope through the difference in angle, the water flow can be directionally converged.

[0032] In actual use, such as Figure 9As shown, frame slope protection bricks A, B, C, and D are stacked from bottom to top. Frame slope protection bricks A11, B21, C31, and D51 are laid flat on the slope surface to form a fixed plane. The hexagonal through holes in the middle of frames A11, B21, and C31 can be used for planting, further fixing the slope soil and giving the slope a certain water retention capacity.

[0033] A frame D51 is installed at the top and bottom of the slope to make the outer contour of the slope top and toe a straight line, thus improving the slope's stability. A diversion channel E61 is installed at the bottom of the slope to collect all the water flowing down the slope.

[0034] By adjusting the position and direction of the diversion channels set on frames A11, B21, and C31, diversion channels A12, B22, and C32 are combined to form a continuous diversion channel, which directly guides the slope drainage into the diversion channel E61, thereby reducing the scouring effect on the slope when there is a large flow on the slope.

[0035] Example 2 Example 1 addresses situations where there are no special facilities at the lower part of the slope. This example addresses situations where the lower part of the slope includes a tunnel exit, and involves assembly. Figure 10 As shown; Starting from the bottom of the slope, lay frame slope protection bricks A, B, and C in sequence from bottom to top, with adjacent frames tightly joined together to ensure that the hexagonal frame covers the main area of ​​the slope. Lay frame-shaped slope protection bricks (trapezoidal frames) at the top and bottom edges of the slope to make the upper and lower outer contours of the slope straight, thereby improving the structural integrity.

[0036] Adjust the angles of frame slope protection bricks A, B, and C to connect diversion channels A12, B22, and C32, forming a continuous flow channel; ensure that the end of the channel is precisely connected to the main diversion channel E61 so that the water flow can smoothly flow into the main diversion channel.

[0037] Fill the central spaces of frames A11, B21, and C31 with planting soil and plant drought-resistant and barren-tolerant herbaceous plants such as bermudagrass and alfalfa, or combine them with shrubs such as purple locust to enhance the ecological protection effect.

[0038] When there is a small flow of runoff on the slope, such as during a short period of rainfall, the water on the slope will seep down through drainage holes A13, B23, and C33 and slowly flow into the diversion channel B22.

[0039] When a large flow of water is generated on the slope, the water converges downwards along the slope under the action of gravity. During the convergence process, the water is guided by the diversion channels A12, B22, and C32, and directly diverted to the diversion channel E61 at the bottom of the slope. This reduces the impact force of the downward flow of water on the tunnel outlets A62 and B63 at the bottom of the diversion channels on the slope.
