Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a slope protection method for water conservancy engineering construction. Background Technology

[0002] Slope protection in water conservancy projects refers to the construction of a protective layer on the slope of a water conservancy project through engineering or ecological measures to prevent soil erosion, enhance slope stability, resist water flow erosion and wind and wave attack, thereby ensuring the safe operation of the main project.

[0003] Existing slope protection methods in water conservancy projects often rely on surface soil stabilization structures combined with vegetation planting. While this approach is cost-effective and provides some reinforcement, it suffers from poor filtration resistance and is prone to internal erosion. To address these issues, an innovative design is proposed based on existing slope protection methods in water conservancy projects. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope protection system for water conservancy engineering construction, comprising an original slope body, a precast cement retaining wall at the top of the original slope body, a vertical rod fixedly installed at the bottom of the precast cement retaining wall, and an anti-settlement plate fixed on the vertical rod; A bottom precast cement retaining wall is set at the bottom of the original slope. A gravel layer is laid on the slope surface between the bottom and top precast cement retaining walls. A fine sand layer is laid on top of the gravel layer. A geotextile layer is laid on top of the fine sand layer. Backfill soil is placed on the geotextile layer. A pre-embedded soil stabilizing net is placed in the backfill soil. The top of the pre-embedded soil stabilizing net is connected and fixed to the bottom of the surface soil stabilizing net. The surface soil stabilizing net is laid on the surface of the backfill soil. A drainage pipe is installed on the top inner side of the precast concrete retaining wall. A diversion pipe is fixed on one side of the drainage pipe. A filter screen is installed inside the diversion pipe. A main anchor nail is installed on the bottom surface of the precast concrete retaining wall.

[0006] Preferably, the side view cross-sectional shape of the top precast cement retaining wall is an isosceles trapezoid, and the top surface of the top precast cement retaining wall is higher than the top surface of the surface soil stabilization net.

[0007] Preferably, the vertical rods are evenly distributed on the bottom surface of the top precast cement retaining wall, and anti-settlement plates are evenly installed on the vertical rods.

[0008] Preferably, the side view of the precast cement retaining wall is a right trapezoid, and the top surface of the precast cement retaining wall is higher than the top surface of the surface soil stabilization net.

[0009] Preferably, the thickness of the gravel layer is greater than the thickness of the fine sand layer, and the thickness of the fine sand layer is not less than the thickness of the geotextile layer.

[0010] Preferably, the pre-embedded soil stabilizing mesh has a continuous "X" shape when viewed from above, and the pre-embedded soil stabilizing mesh is vertically distributed with the geotextile layer.

[0011] Preferably, the drainage pipe is densely and evenly installed with diversion pipes near the surface soil stabilization net, the diameter of the drainage pipe is larger than the diameter of the diversion pipe, and the height of the bottom of the inner wall of the diversion pipe is not lower than the height of the top surface of the bottom of the surface soil stabilization net.

[0014] The slope protection method for water conservancy engineering construction of this utility model has the following beneficial effects: The new structural design not only has a reverse filtration function, allowing water to drain freely, but also prevents soil particles from being carried away by the water flow, avoiding the hollowing out of the slope, but also greatly improves the stability of each part, enabling it to work stably for a long time. 1. The reverse filter mechanism, composed of gravel layer, fine sand layer and geotextile layer, allows water to drain freely while preventing soil particles from being carried away by the water flow, avoiding the hollowing out of the original slope. In conjunction with drainage pipes, diversion pipes and filter screens, it can promptly drain surface runoff and water accumulation when there is heavy rainfall. 2.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a slope protection method for water conservancy engineering construction, including an original slope 1, a top precast cement retaining wall 2, vertical rods 3, anti-settlement plates 4, a bottom precast cement retaining wall 5, a gravel layer 6, a fine sand layer 7, a geotextile layer 8, backfill soil 9, a pre-embedded soil stabilizing net 10, a surface soil stabilizing net 11, a drainage pipe 12, a diversion pipe 13, a filter screen 14, a main anchor nail 15, a support rod 16, a base plate 17, and a secondary anchor nail 18. The top of the original slope 1 is provided with a top precast cement retaining wall 2, and a vertical rod 3 is fixedly installed at the bottom of the top precast cement retaining wall 2. An anti-settlement plate 4 is fixed on the vertical rod 3. A bottom precast cement retaining wall 5 is set at the bottom of the original slope 1. A gravel layer 6 is laid on the slope surface of the original slope 1 between the bottom precast cement retaining wall 5 and the top precast cement retaining wall 2. A fine sand layer 7 is laid on top of the gravel layer 6. A geotextile layer 8 is laid on top of the fine sand layer 7. Backfill soil 9 is set on the geotextile layer 8. A pre-embedded soil stabilizing net 10 is set in the backfill soil 9. The top of the pre-embedded soil stabilizing net 10 is connected and fixed to the bottom of the surface soil stabilizing net 11. The surface soil stabilizing net 11 is laid on the surface of the backfill soil 9. A drainage pipe 12 is installed on the top inner side of the precast concrete retaining wall 5. A diversion pipe 13 is fixed on one side of the drainage pipe 12. A filter screen 14 is installed inside the diversion pipe 13. A main anchor nail 15 is installed on the bottom surface of the precast concrete retaining wall 5.

[0024] In this example, the side view of the precast cement retaining wall 2 is an isosceles trapezoid. The top surface of the precast cement retaining wall 2 is higher than the top surface of the surface soil stabilization net 11. The above structural design can improve the stability of the precast cement retaining wall 2 and prevent rainwater from flowing downwards from the top of the slope.

[0025] In this example, the vertical rods 3 are evenly distributed on the bottom surface of the top precast cement retaining wall 2, and anti-settlement plates 4 are evenly installed on the vertical rods 3. The above structural design can improve the stability of the top precast cement retaining wall 2 and prevent the top precast cement retaining wall 2 from settling.

[0026] In this example, the side view of the precast cement retaining wall 5 is a right trapezoid. The top surface of the precast cement retaining wall 5 is higher than the top surface of the surface soil stabilization net 11. The above structural design can prevent surface runoff from carrying away soil and ensure that the precast cement retaining wall 5 has high stability.

[0027] In this example, the thickness of the gravel layer 6 is greater than the thickness of the fine sand layer 7, and the thickness of the fine sand layer 7 is not less than the thickness of the geotextile layer 8. The above structural design has a better reverse filtration effect and avoids the loss of backfill soil 9.

[0028] In this example, the top view of the pre-embedded soil stabilization net 10 is a continuous "X" shape. The pre-embedded soil stabilization net 10 and the geotextile layer 8 are vertically distributed. The above structural design can reinforce the backfill soil 9 and further prevent the backfill soil 9 from being lost.

[0029] In this example, drainage pipes 12 are densely installed at equal intervals on the side close to the surface soil stabilization net 11. The diameter of drainage pipe 12 is larger than the diameter of drainage pipe 13. The height of the bottom of the inner wall of drainage pipe 13 is not lower than the height of the top surface of the bottom of surface soil stabilization net 11. The above structural design can discharge surface runoff in a timely manner and avoid water accumulation.

[0030] In this example, a support rod 16 is rotatably installed on the top of the inclined surface of the precast concrete retaining wall 5. The bottom end of the support rod 16 is rotatably connected to the top surface of the base plate 17. A secondary anchoring nail 18 is provided on the bottom surface of the base plate 17. The above structural design can reinforce the precast concrete retaining wall 5 and further improve the stability of the precast concrete retaining wall 5.

[0031] In this example, the center of the support rod 16 and the center of the base plate 17 are on the same vertical plane. The support rod 16 is symmetrically distributed about the center of the bottom precast cement retaining wall 5. The above structural design enables the support rod 16 and the base plate 17 to stably support and position the bottom precast cement retaining wall 5, and stably position the bottom of the gravel layer 6, fine sand layer 7, geotextile layer 8 and backfill soil 9.

[0032] Working principle: When the slope protection structure is working, the gravel layer 6, fine sand layer 7 and geotextile layer 8 have a reverse filtration effect, allowing rainwater to infiltrate downwards and drain freely, while preventing soil particles from being carried away by the water flow, avoiding the hollowing out of the backfill soil 9. The gaps in the surface soil stabilization net 11 on the surface of the backfill soil 9 can also be planted with vegetation. In conjunction with the pre-embedded soil stabilization net 10, the protection effect on the backfill soil 9 is further improved. The drainage pipe 12 and the diversion pipe 13 can discharge the surface runoff generated when the rainfall is large in a timely manner, avoiding water accumulation and also slowing down the surface soil erosion. The filter net 14 is cleaned regularly to avoid clogging. The vertical rod 3 and the anti-settlement plate 4 can increase the contact area with the original slope 1 soil and prevent the top precast cement retaining wall 2 from settling. The main anchor nail 15, support rod 16, base plate 17 and secondary anchor nail 18 can provide stable support for the bottom precast cement retaining wall 5 and ensure the long-term stability of the bottom of the slope.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
