Description

Technical Field

[0001] This utility model relates to the field of greening and protection structure technology, specifically a greening and protection structure for retaining walls on plateau highway slopes. Background Technology

[0002] Green protective structures are an important component of retaining walls on plateau highway slopes, aiming to improve slope stability and ecological environment quality through vegetation cover and soil stabilization. Due to their unique climate and geological environment, plateau regions are prone to slope erosion from wind and water, leading to increased risk of slope loosening and collapse. Green protective structures not only effectively reduce the damage to the slope caused by rainwater runoff but also enhance the overall soil strength through the reinforcing effect of plant roots, preventing landslides and debris flows.

[0003] Traditional drainage systems often employ fixed floor drains, requiring manual excavation and cleaning after siltation. This is inefficient in the low-pressure, oxygen-deficient environment of high altitudes, and the cleaning process can easily damage the drainage structure. Slope drainage and vegetation soil stabilization systems often operate independently, lacking coordinated design. This makes drainage channels prone to blockage by plant roots, and the inability to effectively divert infiltrated water can lead to soil saturation and landslides in vegetated areas. Existing retaining wall drainage channels mostly use linear structures, which are easily blocked by snowmelt or rainwater carrying gravel. Furthermore, they lack modular designs for rapid repair, increasing maintenance risks in harsh high-altitude environments. These shortcomings directly affect the long-term stability and ecological effectiveness of high-altitude highway slope protection systems. Utility Model Content

[0004] The purpose of this utility model is to provide a greening and protection structure for retaining walls on plateau highway slopes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a greening and protection structure for a retaining wall on a plateau highway, comprising a slope structure and a drainage ditch. A road surface is provided on one side of the slope structure, and a drainage ditch is provided between the slope structure and the road surface. A drainage channel is provided at the top of the drainage ditch, and a cleaning structure is slidably connected between the inner walls of the drainage channel. A fixing block is fixedly connected to the top of the drainage ditch, and drain plates are rotatably connected to both sides of the fixing block and the inner walls of the drainage ditch. Drainage grooves are provided at equal intervals inside the drain plates. The side of the slope structure closest to the road surface is a sloping structure, and a supporting structure is fixedly connected to the outer side of the sloping structure. A vegetation zone is provided between the inner walls of the supporting structure, and drainage holes and a guide channel are provided inside the supporting structure. The lower end of the guide channel is directly opposite the drainage ditch.

[0006] As a further preferred embodiment of this technical solution, the cleaning structure includes a movable plate, which is slidably connected between the inner walls of the drainage trough. Triangular shovels are fixedly connected to both sides of the movable plate. A top plate is provided on the top of the movable plate, and a groove is opened on the top of the top plate. A handle is rotatably connected between the inner walls of the groove.

[0007] As a further preferred embodiment of this technical solution, triangular stabilizing grooves are provided on both sides of the inner wall of the drainage trough, and triangular stabilizing blocks are fixedly connected to both sides of the movable plate. The outer side of the triangular stabilizing block is slidably connected to the inner wall of the triangular stabilizing groove.

[0008] As a further preferred embodiment of this technical solution, the top of the movable plate is provided with an embedding groove, and the bottom of the top plate is fixedly connected to a connecting plate, the outer side of the connecting plate being slidably connected to the inner wall of the embedding groove.

[0009] As a further preferred embodiment of this technical solution, the inner wall of the embedding groove is provided with limiting grooves on both sides, and the connecting plate is provided with limiting plates on both sides, with the outer side of the limiting plate slidably connected to the limiting groove.

[0011] As a further preferred embodiment of this technical solution, a protective railing is fixedly connected to the top of the slope structure.

[0012] This utility model provides a greening and protection structure for retaining walls on plateau highway slopes, which has the following beneficial effects:

[0013] (1) This utility model cleans the inside of the drainage channel through a cleaning structure, avoiding the accumulation of mud and sand that affects the drainage effect. The movable drain plate makes it convenient for staff to carry out daily maintenance, simplifies the work, reduces working time, and facilitates the use of retaining walls on the slopes of plateau highways. Specifically, the triangular shovels on both sides of the movable plate can effectively remove the mud and sand deposited in the drainage channel. The cooperation between the triangular stabilizing block and the triangular stabilizing groove ensures the structural stability during the cleaning process. The rotatable handle and the detachable top plate design further improve the convenience of maintenance operations and significantly reduce the difficulty of manual maintenance in the harsh environment of the plateau.

[0014] (2) This utility model solidifies the slope structure through the vegetation zone, and guides rainwater or other accumulated water through the drainage holes and diversion channels on the supporting structure, effectively preventing water accumulation and soil erosion. The plant roots in the vegetation zone can penetrate deep into the slope soil to form a network reinforcement, while the diversion channels in the supporting structure direct the infiltrated water to the drainage channel, and the drainage holes ensure that excess water is discharged in time. This dual protection mechanism maintains the water content balance of the slope soil and avoids soil erosion caused by water flow through the scientific drainage path design. It is particularly suitable for the special climatic conditions of heavy rainfall and freeze-thaw cycles in plateau areas, and significantly improves the long-term stability and ecological benefits of the retaining wall structure.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-4As shown in this embodiment, a greening and protection structure for a retaining wall on a plateau highway includes a slope structure 1 and a drainage ditch 3. A road surface 2 is provided on one side of the slope structure 1, and a drainage ditch 3 is provided between the slope structure 1 and the road surface 2. A drainage channel 7 is provided at the top of the drainage ditch 3, and a cleaning structure is slidably connected between the inner walls of the drainage channel 7. A fixing block 9 is fixedly connected to the top of the drainage ditch 3, and drain plates 13 are rotatably connected between the two sides of the fixing block 9 and the inner walls of the drainage ditch 3. Drainage grooves 14 are provided at equal intervals inside the drain plates 13. The side of the slope structure 1 closest to the road surface 2 is a sloping structure, and a supporting structure 4 is fixedly connected to the outer side of the sloping structure. A vegetation area 5 is provided between the inner walls of the supporting structure 4. A drainage through hole 11 and a guide channel 12 are provided inside the supporting structure 4, and the lower end of the guide channel 12 is directly opposite the drainage channel 7. A guardrail 6 is fixedly connected to the top of the slope structure 1.

[0022] When rainfall occurs, runoff from road surface 2 first enters the drainage channel 7 of drainage ditch 3 through the drain trough 14 of drain plate 13. Simultaneously, water flowing from the surface of slope structure 1 is guided by the drainage holes 11 and guide channels 12 of supporting structure 4 and flows into drainage channel 7, achieving efficient drainage. The plant roots in vegetation zone 5 stabilize the slope soil, while excess water seeps out through the drainage holes 11 of supporting structure 4, preventing soil saturation. During routine maintenance, the movable plate 15 of the cleaning structure can be pulled by handle 25, allowing the triangular shovels 16 on both sides to remove sediment from drainage channel 7. The cooperation between triangular stabilizing block 17 and triangular stabilizing groove 8 ensures cleaning stability. When drain plate 13 needs maintenance, it can be rotated around fixed block 9 to open for cleaning or replacement. Guardrail 6 prevents falling rocks from the slope top from endangering road safety. The entire structure achieves long-term stable protection of plateau highway slopes through the synergistic effect of vegetation soil stabilization, scientific drainage, and convenient maintenance.

[0023] like Figures 1-4 As shown, the cleaning structure includes a movable plate 15, which is slidably connected to the inner wall of the drainage trough 7. Triangular shovels 16 are fixedly connected to both sides of the movable plate 15. A top plate 20 is provided on the top of the movable plate 15, and a slot 24 is opened on the top of the top plate 20. A handle 25 is rotatably connected to the inner wall of the slot 24. Triangular stabilizing slots 8 are opened on both sides of the inner wall of the drainage trough 7. Triangular stabilizing blocks 17 are fixedly connected to both sides of the movable plate 15, and the outer side of the triangular stabilizing blocks 17 is slidably connected to the inner wall of the triangular stabilizing slots 8. Next, the top of the movable plate 15 is provided with an embedding groove 18, and the bottom of the top plate 20 is fixedly connected with a connecting plate 21. The outer side of the connecting plate 21 is slidably connected to the inner wall of the embedding groove 18. Limiting grooves 19 are provided on both sides of the inner wall of the embedding groove 18. Limiting plates 22 are provided on both sides of the connecting plate 21. The outer side of the limiting plate 22 is slidably connected to the limiting groove 19. The top of the fixing block 9 is provided with a fixing groove 10, and a locking block 23 is rotatably connected to one side of the top plate 20. The outer side of the locking block 23 is in contact with the inner wall of the fixing groove 10.

[0024] The operator lifts the top plate 20 by turning the handle 25, causing the locking block 23 to move out of the fixed groove 10. Then, the locking block 23 is rotated so that it is perpendicular to the top plate 20. The operator then moves the handle 25 manually or mechanically to make the connecting plate 21 drive the moving plate 15 to slide along the drainage groove 7. The triangular shovels 16 on both sides of the moving plate 15 remove the sediment in the groove during the sliding process. At the same time, the triangular stabilizing block 17 and the triangular stabilizing groove 8 cooperate to ensure the stability of the movement. After cleaning, the connecting plate 21 of the top plate 20 is re-embedded into the embedding groove 18 of the moving plate 15. The limiting plate 22 and the limiting groove 19 cooperate to achieve precise positioning. Finally, the locking block 23 is rotated to lock into the fixed groove 10 of the fixed block 9 to complete the fixation. This design realizes efficient cleaning and convenient maintenance of the drainage system.

[0025] This utility model provides a greening and protection structure for retaining walls on plateau highway slopes. The specific working principle is as follows: During rainfall, runoff from the road surface 2 enters the drainage channel 7 of the drainage ditch 3 through the drain trough 14 of the drain plate 13. Simultaneously, runoff from the surface of the slope structure 1 is guided by the guide channel 12 and drainage holes 11 of the supporting structure 4 and directed into the drainage channel 7, achieving efficient drainage. The plant roots in the vegetation zone 5 consolidate the slope soil, while the drainage holes 11 ensure balanced soil moisture. During routine maintenance, the operator rotates the handle 25 to lift the top plate 20, allowing... Locking block 23 disengages from fixed groove 10, pushing moving plate 15 to drive triangular shovel 16 to remove sediment from drainage groove 7. Triangular stabilizing block 17 and triangular stabilizing groove 8 cooperate to ensure cleaning stability. After cleaning, the top plate 20 is precisely reset and locked by the cooperation of limiting plate 22 and limiting groove 19. Drain plate 13 can be rotated and flipped around fixed block 9 for easy maintenance. Guardrail 6 prevents rockfall hazards from the top of the slope. The whole structure effectively copes with the special climate conditions of the plateau through the synergistic effect of vegetation slope stabilization, scientific drainage and convenient maintenance, and achieves long-term stable protection of the slope.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
