Description

Technical Field

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

[0002] Slope protection refers to measures taken to protect the slope surface of embankments and cuttings exposed to the atmosphere from damage such as peeling, crumbling, erosion, or surface soil collapse. Traditional slope protection methods often include wire mesh installation, plastering, grouting, or retaining walls. However, current slope protection measures must not only consider safety but also integrate with ecological considerations.

[0003] Therefore, existing slope protection structures all use the method of fixing the slope with vegetation to fix the slope. However, the problems faced by plants in high-altitude and cold regions include strong winds, drought and temperature differences. Existing slope protection structures lack effective solutions for the environment in high-altitude and cold regions, which leads to difficulties in ecological slope protection in high-altitude and cold regions.

[0004] Therefore, we need to design a highway slope protection structure suitable for cold-region ecosystems to solve these problems. Utility Model Content

[0005] The problem this invention aims to solve is to provide a highway slope protection structure suitable for cold-region ecosystems.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A highway slope protection structure suitable for cold-region ecosystems includes a top slope channel and a bottom slope channel, and a connecting trough. The connecting trough is located on the slope between the top slope channel and the bottom slope channel and is connected to both channels. Several guide frames and several guide blocks are arranged at the bottom inner side of the connecting trough. The guide frames are arranged sequentially along the centerline of the connecting trough, and the guide blocks are symmetrically distributed along the guide frames. A rooting layer and several diversion pipes are respectively arranged on both sides of the connecting trough. The rooting layer is laid on the slope on both sides of the connecting trough. The positions of the diversion pipes correspond one-to-one with the positions of the guide blocks and are buried within the rooting layer. Irrigation holes and planting nets are also provided on the diversion pipes. The planting nets are located on the surface of the rooting layer and are detachably connected to the diversion pipes. The planting nets on adjacent diversion pipes are connected.

[0007] Preferably, an inlet is provided on the top slope channel, and the connecting trough is connected to the top slope channel through the inlet. A sludge separator is provided inside the inlet. An outlet is provided on the bottom slope channel, and the connecting trough is connected to the bottom slope channel through the outlet.

[0008] This design allows the water inlet at the top of the slope to flow into the connecting channel in an orderly manner, preventing direct overflow and erosion of the slope. The debris filter, located inside the inlet, filters out debris such as dead branches and stones from the water flow, preventing them from entering the connecting channel and clogging the guide frame, guide block, or diversion pipe, ensuring smooth drainage. This is especially suitable for situations where there may be fallen leaves, frozen snow, or other debris in cold regions. The outlet at the bottom of the slope discharges the water from the connecting channel, preventing water from accumulating in the connecting channel or the slope, reducing damage to the slope and protective structure caused by freeze-thaw cycles (water freezing and expansion) in cold regions, and ensuring the stability of the overall structure.

[0009] Preferably, the guide frame has a V-shaped structure with its tip pointing towards the top of the slope channel. The guide block is located between two adjacent guide frames and is fixedly connected to the bottom and inner wall of the connecting groove, respectively. The angle between the guide block and the inner wall of the connecting groove does not exceed 90 degrees, and the opening of the angle faces the top of the slope channel.

[0010] With this configuration, the guide frame adopts a V-shaped structure with its tip pointing towards the top of the slope channel. When water flows from the top of the slope channel into the connecting trough, the V-shaped structure can divert the water flow to both sides. The guide block is located between adjacent guide frames, with the angle between it and the inner wall of the connecting trough not exceeding 90 degrees and its opening facing the top of the slope channel. This can intercept a portion of the water flow and guide it into the diversion pipe, which then flows into the rooting layer through the irrigation holes on the diversion pipe. At the same time, the diversion pipe can also divert excess water in the rooting layer to the connecting trough for discharge, preventing water from accumulating in the connecting trough or the slope. This reduces the damage to the slope and protective structure caused by the freeze-thaw cycle of water accumulation and expansion in cold regions, ensuring the stability of the overall structure.

[0011] Preferably, an installation groove is provided at the bottom of the water inlet, a limiting groove is provided on a set of opposite inner walls of the water inlet, a limiting block is provided on a set of opposite outer walls of the dirt separator, the bottom of the dirt separator mesh matches the installation groove, and the limiting block matches the limiting groove.

[0012] With this design, the mounting groove at the bottom of the inlet and the limiting groove on the inner wall match the bottom and limiting block of the baffle, allowing the baffle to be stably installed inside the inlet and preventing it from shifting or tipping over under the impact of water flow. At the same time, this structural design facilitates the disassembly and installation of the baffle. When a lot of debris accumulates on the baffle, it can be quickly removed, cleaned, and reinstalled to ensure unobstructed water flow and reduce maintenance difficulty.

[0013] Preferably, a fixing post is fixedly installed on the diversion pipe, and a fixing hole is opened on the planting net, the fixing hole matching the fixing post; a fixing groove is opened on one side wall of the planting net, and a connecting block is fixedly installed on the other opposite side wall, the connecting block matching the fixing groove.

[0014] With this setup, the fixing posts on the distribution pipe match the fixing holes of the planting net, enabling a detachable connection between the planting net and the distribution pipe. This facilitates replacing the planting net or adjusting its position according to the vegetation's growth needs. The fixing groove on one side of the planting net matches the connecting block on the other side, allowing adjacent planting nets to be firmly connected, forming an integrated coverage structure. This enhances the fixation effect on the rooting layer, preventing the planting net from being lifted off-center by cold winds or water flow. At the same time, the integrated planting net provides a stable growth carrier for the vegetation, helping to evenly cover the slope.

[0015] Preferably, both the connecting block and the fixing groove have a T-shaped cross-section.

[0016] With this design, the connecting block and the fixing groove have a T-shaped cross-section. The T-shaped structure has a larger contact surface and a mutual limiting effect, which makes the connection between adjacent planting nets more stable. It is not easy to separate due to strong winds, water flow impacts, or micro-deformation of the structure caused by freeze-thaw cycles in cold regions. This ensures the continuity of the overall coverage of the planting net and further enhances the protective effect on the rooting layer and the surface of the slope.

[0017] Preferably, the screen is also provided with a hand grip groove.

[0018] This design provides operators with convenient leverage points for gripping the screen when disassembling or installing the screen. Especially in cold regions, where operators may be wearing gloves or the screen may be slightly stuck due to freezing, the grips reduce the difficulty of operation, improve maintenance efficiency, and ensure timely cleaning and repositioning of the screen.

[0019] The advantages and positive effects of this utility model are: This utility model forms a comprehensive protection system that integrates drainage and ecological restoration. The connecting trough connects the top and bottom channels of the slope, guiding water flow across the slope surface in an orderly manner and preventing disorderly erosion that could lead to soil loss. This is particularly suitable for loose, easily eroded slopes in cold regions. The rooting layer provides a suitable environment for the root growth of vegetation in cold regions, helping it to take root and stabilize the slope. The diversion pipes correspond to the guide blocks and are buried within the rooting layer. Combined with irrigation holes, water can be precisely introduced into the rooting layer to provide moisture to the vegetation. The guide frame is arranged along the centerline, and the guide blocks are symmetrically distributed, effectively distributing water to each diversion pipe during droughts, alleviating water shortages caused by drought or freeze-thaw cycles in cold regions. The planting net covers the rooting layer and is detachably connected to the diversion pipes. This not only secures the rooting layer from erosion but also allows for easy replacement or adjustment based on vegetation growth. Adjacent planting nets are connected to form a unified cover, further enhancing the fixation effect on the slope surface and strengthening slope stability. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The present invention will be further described below with reference to the accompanying drawings: Example 1: As Figures 1-7 As shown, a highway slope protection structure suitable for cold-region ecosystems includes a top slope channel 1 and a bottom slope channel 15, as well as a connecting trough 5. The connecting trough 5 is located on the slope 17 between the top slope channel 1 and the bottom slope channel 15 and is connected to the top slope channel 1 and the bottom slope channel 15. Several guide frames 6 and several guide blocks 7 are provided at the bottom of the inner side of the connecting trough 5. The several guide frames 6 are arranged one by one along the center line of the connecting trough 5, and the several guide blocks 7 are symmetrically distributed along the guide frames 6. Rooting layers 19 and several diversion pipes 8 are respectively provided on both sides of the connecting trough 5. The rooting layers 19 are laid on the slope 17 on both sides of the connecting trough 5. The positions of the several diversion pipes 8 correspond one by one with the positions of the several guide blocks 7 and are buried in the rooting layers 19. Irrigation holes 9 and planting nets 11 are also provided on the diversion pipes 8. The planting nets 11 are located on the surface of the rooting layers 19 and are detachably connected to the diversion pipes 8. The planting nets 11 on adjacent diversion pipes 8 are connected.

[0026] The top slope channel 1 receives water from the top of the slope. The connecting channel 5, through its connection with the top slope channel 1 and the bottom slope channel 15, forms the main drainage channel that runs through the slope 17. The guide frame 6 is arranged along the center line and the guide blocks 7 are symmetrically distributed. This can divert and guide the water flow in the connecting channel 5. Some of the water flow is guided through the guide blocks 7 to the corresponding diversion pipe 8. The diversion pipe 8 is buried in the rooting layer 19 and supplies water to the rooting layer 19 through the irrigation hole 9. At the same time, the planting net 11 covers the surface of the rooting layer 19 and is connected to the diversion pipe 8. After the adjacent planting nets 11 are connected, they form an overall protective layer, realizing the linkage between drainage and ecological protection. In addition, in order to prevent soil from entering the diversion pipe 8 from the irrigation hole 9 and blocking the diversion pipe 8, a non-woven fabric isolation net is wrapped around the outside of the diversion pipe 8 for isolation.

[0027] An inlet 2 is provided on the top slope channel 1, and the connecting channel 5 is connected to the top slope channel 1 through the inlet 2. A sludge separator 4 is provided inside the inlet 2. An outlet 18 is provided on the bottom slope channel 15, and the connecting channel 5 is connected to the bottom slope channel 15 through the outlet 18.

[0028] The inlet 2 of the slope top channel 1 is the only channel through which water from the slope top enters the connecting trough 5. The water in the connecting trough 5 flows into the slope bottom channel 15 through the outlet 18, thus forming a drainage path from the top of the slope to the bottom of the slope. This facilitates water intake to irrigate the rooting layer 19 during the drainage process. The dirt separator 4 is installed in the inlet 2 and can perform preliminary filtration of the water entering the connecting trough 5 to prevent debris from entering the connecting trough 5 with the water flow. This also prevents the guide frame 6, guide block 7, or diversion pipe 8 from being blocked, ensuring the smooth flow of the drainage channel.

[0029] The guide frame 6 has a V-shaped structure, with its tip pointing towards the top of the slope channel 1. The guide block 7 is located between two adjacent guide frames 6 and is fixedly connected to the bottom and inner wall of the connecting trough 5 respectively. The angle between the guide block 7 and the inner wall of the connecting trough 5 does not exceed 90 degrees, and the opening of the angle faces the top of the slope channel 1.

[0030] The guide frame 6 adopts a V-shaped structure with its tip pointing towards the top of the slope channel 1. When water flows from the top of the slope channel 1 into the connecting trough 5, the two side walls of the V-shaped structure can divert the water flow to both sides of the connecting trough 5. Then, the diverted water can be gathered by the guide blocks 7 on both sides and introduced into the diversion pipe 8. The water is then irrigated into the rooting layer 19 through the diversion pipe 8 to provide water for plant growth. This is more suitable for water collection and utilization during relatively dry periods.

[0031] An installation groove 3 is provided at the bottom of the inlet 2. A limiting groove 20 is provided on a set of opposite inner walls of the inlet 2. A limiting block 21 is provided on a set of opposite outer walls of the dirt separator 4. The bottom of the dirt separator mesh matches the installation groove 3, and the limiting block 21 matches the limiting groove 20.

[0032] The mounting groove 3 at the bottom of the inlet 2 matches the bottom of the baffle 4, which can vertically position the baffle 4; the limiting groove 20 on the inner wall of the inlet 2 matches the limiting block 21 on the outer wall of the baffle 4, which can horizontally limit the baffle 4; the two together can firmly fix the baffle 4 in the inlet 2, preventing the baffle 4 from shifting or tipping over due to water flow impact; at the same time, by using the combination of the mounting groove 3 and the limiting groove 20, the baffle 4 can be vertically disassembled along the limiting groove 20, which is convenient for regular removal and cleaning of debris, ensuring the baffle effect.

[0033] A fixing post 10 is fixedly installed on the diversion pipe 8, and a fixing hole 12 is opened on the planting net 11. The fixing hole 12 matches the fixing post 10. A fixing groove 13 is opened on one side wall of the planting net 11, and a connecting block 14 is fixedly installed on the other opposite side wall. The connecting block 14 matches the fixing groove 13.

[0034] The fixing post 10 on the diversion pipe 8 matches the fixing hole 12 of the planting net 11, which can detachably fix the planting net 11 to the diversion pipe 8, so that the planting net 11 can stably cover the surface of the rooting layer 19 and prevent the planting net 11 from shifting due to wind or water flow. The fixing groove 13 on one side of the planting net 11 matches the connecting block 14 on the other side, which can connect the planting nets 11 on adjacent diversion pipes 8 to form an overall protective net covering the slope 17 on both sides of the connecting groove 5, which enhances the fixing effect on the rooting layer 19 and enables the plants to resist strong winds.

[0035] Both the connecting block 14 and the fixing groove 13 have a T-shaped cross-section.

[0036] The connecting block 14 and the fixing groove 13 adopt a T-shaped cross section. When adjacent planting nets 11 are connected to the fixing groove 13 through the connecting block 14, the transverse part of the T-shaped structure can interlock with each other, realizing the interconnection of planting nets 11, enhancing stability, avoiding the separation of planting nets 11 caused by strong winds or water flow in cold regions, and ensuring the continuity and strength of the overall protective net.

[0037] Hand grip grooves 22 are also provided on the dirt-proof netting.

[0038] The handle groove 22 on the screen provides a leverage point for the operator. When the screen needs to be disassembled for cleaning, the operator can easily remove the screen from the installation groove 3 and the limiting groove 20 of the inlet 2 through the handle groove 22. After cleaning, the screen can be reset through the handle groove 22, which simplifies the disassembly and installation process of the screen and improves maintenance efficiency.

[0039] The construction process of this embodiment is as follows: First, the slope 17 to be constructed is leveled. Then, the top channel 1 is fixed at the top of the slope 17, and the bottom channel 15 is fixed at the bottom of the slope. Next, the connecting groove 5 is installed on the slope 17. One end of the connecting groove 5 is connected to the inlet 2 on the top channel 1, and the other end is connected to the outlet 18 on the bottom channel 15. Then, the diversion pipes 8 are installed on both sides of the connecting groove 5. After the diversion pipes 8 are installed, soil is filled into the slope between the two connecting grooves 5 and the rooting layer 19 is laid flat. Plant seeds are sown in the rooting layer 19, and the soil is compacted to a level suitable for plant growth. The diversion pipes 8 are buried in the rooting layer 19. The water flowing from the top channel 1 to the bottom channel 15 is introduced into the diversion pipes 8 using the guide frame 6 and the guide block 7 to irrigate the rooting layer 19 and provide sufficient water for plant growth.

[0040] Finally, cover the connecting groove 5 with the protective cover 16, and at the same time, use the limiting groove 20 and the limiting block 21 to install the dirt screen into the installation groove 3 at the water inlet 2 to block the debris in the water flowing into the connecting groove 5 and prevent the debris from falling in and causing water blockage.

[0041] Although the diversion pipe 8 is buried in the rooting layer 19 during its installation, the fixing post 10 on the diversion pipe 8 is exposed on the surface of the rooting layer 19, which facilitates the fixing of the planting net 11. When the plants sprout, they will emerge from the rooting layer 19 and grow out of the grid on the planting net 11. The plant net fixed on the diversion pipe 8 can block strong winds before the plants grow, preventing the rooting layer 19 from being blown away by strong winds.

[0042] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
