Description

Technical Field

[0001] This application relates to the field of slope protection structure technology, specifically a slope protection structure for water conservancy engineering design to prevent soil erosion. Background Technology

[0002] Slope protection refers to the various paving and plantings done on the slope surface to prevent erosion. In water conservancy projects, slope protection must be built on the concave bank to protect the safety of bridges and embankments.

[0003] An existing patent (publication number: CN219430663U) discloses a slope protection structure for water conservancy engineering, specifically relating to the field of slope protection technology. The structure includes a slope body with a drainage mechanism on one side. This drainage mechanism comprises a waterproof concrete slope layer, which is located on one side of the slope body. The slope body is reinforced with reinforced concrete, and protective bricks are installed on one side of the waterproof concrete slope layer. Drainage pipes are installed inside the protective bricks. This invention, through the drainage mechanism and installation / disassembly mechanism, allows water impacting the slope to be discharged through drainage pipes and channels, effectively preventing water accumulation and flow into the slope body, thus avoiding soil erosion. It also facilitates the replacement of protective bricks, eliminating the need for extensive time-consuming maintenance of damaged slope areas, improving maintenance efficiency, and saving time and effort. Simultaneously, the reinforced concrete reinforcement significantly enhances the slope's impact resistance, making it more robust and increasing its strength.

[0004] However, during the use of the above-mentioned slope protection, road surface water can easily wash impurities onto the slope, causing the filter screen to become clogged and affecting its drainage performance. Secondly, when the water level rises, it can easily submerge the drainage ditch, causing drainage difficulties. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a slope protection structure for water conservancy engineering design to prevent soil erosion, which has advantages such as erosion prevention and solves the problems in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a slope protection structure for water conservancy engineering to avoid soil erosion, comprising a slope body, a drainage cavity being provided inside the slope body, multiple sets of permeable holes being provided on the right side of the slope body, and multiple load-bearing walls arranged at equal intervals being fixedly connected to the inner sidewall of the drainage cavity.

[0007] The upper surface of the slope is provided with a permeable layer, a protective net layer, a planting soil layer and a vegetation layer from bottom to top. The right end of the slope is rotatably connected to a rotating shaft. A water-blocking plate is fixedly connected to the outer surface of the rotating shaft. The top of the water-blocking plate is in the shape of a right-flipping arc. Multiple spring dampers arranged at equal intervals are hinged between the water-blocking plate and the bottom end of the slope.

[0008] The above scheme, by setting drainage chambers and permeable holes inside the slope and combining them with the design of water-retaining plates, effectively guides and slows down the water flow, significantly reducing the direct scouring force of the water flow on the slope surface. At the same time, it ensures that the water flows smoothly into the drainage chamber, avoiding water accumulation and damage to the slope. The permeable layer, protective netting layer, planting soil layer, and vegetation layer form an efficient soil conservation system that allows water infiltration while effectively preventing soil loss. It also provides a good growth substrate for vegetation, enhancing the soil and water conservation effect. The application of spring dampers can buffer the impact force of the water flow and slow down the water flow speed.

[0009] Furthermore, the protective mesh layer is composed of corrosion-resistant, high-strength metal mesh or synthetic fiber mesh, and is anchored to the slope.

[0010] The above method can prevent gravel from rolling down.

[0011] Furthermore, a drainage groove is provided at the bottom end of the water baffle.

[0012] The above solution facilitates the drainage of rainwater from the vegetation layer during rainfall, preventing water accumulation from damaging the vegetation.

[0013] Furthermore, a connecting groove is provided at the bottom front end of the load-bearing wall.

[0014] The above method can keep the water level inside the drainage chamber at the same level, ensuring uniform drainage effect.

[0015] Furthermore, a municipal sewage pipe is fixedly embedded at the bottom of the slope, and multiple drainage holes penetrating the inner wall of the municipal sewage pipe are provided on the inner bottom wall of the drainage cavity.

[0016] The above method is used to drain the accumulated water in the drainage chamber into the municipal sewage system.

[0017] Furthermore, the vegetation layer is dominated by vetiver as its main plant species.

[0018] Through the above methods, vetiver grass is known for its extremely developed root system, which can penetrate several meters deep into the soil to form a dense root network that tightly fixes soil particles together, thereby significantly enhancing soil stability and erosion resistance.

[0019] Furthermore, a curbstone is fixedly connected to the top left side of the upper surface of the slope.

[0020] The above-mentioned measures are used to prevent road water accumulation from eroding the vegetation layer and to protect the integrity of the slope structure.

[0021] Furthermore, the permeable layer is gravel.

[0022] The above solution exhibits good water permeability and filtration performance.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This water conservancy engineering design prevents soil erosion by incorporating drainage chambers and permeable holes within the slope, combined with a water-retaining plate design. This effectively guides and slows down the water flow, significantly reducing the direct scouring force of the water flow on the slope surface. Simultaneously, it ensures smooth drainage into the drainage chambers, preventing water accumulation and damage to the slope. The permeable layer, protective netting layer, planting soil layer, and vegetation layer form a highly efficient soil conservation system that allows water infiltration while effectively preventing soil erosion. It also provides a good growth substrate for vegetation, enhancing soil and water conservation. The application of spring dampers buffers the impact force of the water flow, slowing down its velocity. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 and Figure 3This embodiment of a water conservancy engineering design for a slope protection structure to prevent soil erosion includes a slope body 1. The slope body 1 has a drainage cavity inside. The right side of the slope body 1 has multiple sets of permeable holes 2 for guiding water flow into the drainage cavity. The inner side wall of the drainage cavity is fixedly connected with multiple load-bearing walls 3 arranged at equal intervals to enhance the structural stability of the slope body 1. The bottom front end of the load-bearing wall 3 has a connecting groove 12, which can keep the water level inside the drainage cavity at the same level and ensure uniform drainage effect.

[0032] Please see Figure 1 and Figure 3 The upper surface of the slope 1 is provided with a permeable layer 4, a protective net layer 5, a planting soil layer 6, and a vegetation layer 7 from bottom to top. The permeable layer 4 allows water to infiltrate while preventing soil loss. The protective net layer 5 prevents soil and gravel from sliding down. The planting soil layer 6 provides a growth substrate for vegetation. The vegetation layer 7 fixes the soil through plant roots and enhances the soil and water conservation effect. The permeable layer 4 is made of gravel and has good permeability and filtration performance. The protective net layer 5 is made of corrosion-resistant, high-strength metal mesh or synthetic fiber mesh and is anchored to the slope 1 to prevent gravel from rolling down.

[0033] Please see Figure 1 and Figure 3 The vegetation layer 7 is mainly composed of vetiver grass, which is known for its extremely developed root system. Its roots can penetrate several meters deep into the soil, forming a dense root network that tightly fixes soil particles together, thereby significantly enhancing soil stability and erosion resistance. The bottom end of the water-retaining plate 9 is provided with a drainage groove 11, which facilitates the drainage of rainwater from the vegetation layer 7 during rainfall, preventing water accumulation from damaging the vegetation. The right end of the slope 1 is rotatably connected to a rotating shaft 8, and the outer surface of the rotating shaft 8 is fixedly connected to the water-retaining plate 9. The top of the water-retaining plate 9 is in the shape of a right-flipping arc, which can automatically flip and slow down the water flow when impacted by water. Multiple equidistant spring dampers 10 are hinged between the water-retaining plate 9 and the bottom end of the slope 1 to adjust the flipping angle of the water-retaining plate 9 and absorb the impact force of the water flow.

[0034] Please see Figure 2 and Figure 3 The bottom end of the slope 1 is fixedly embedded with a municipal sewage pipe 13. The inner bottom wall of the drainage cavity is provided with a plurality of drainage holes 14 that penetrate the inner wall of the municipal sewage pipe 13, which are used to drain the water in the drainage cavity into the municipal sewage system. The top left side of the upper surface of the slope 1 is fixedly connected with a curb stone 15 to prevent road water from washing away the vegetation layer 7 and to protect the integrity of the slope 1 structure.

[0035] This embodiment of a water conservancy engineering design for a slope protection structure to prevent soil erosion involves setting drainage chambers and permeable holes 2 inside the slope 1, combined with the design of water-retaining plates 9, to effectively guide and slow down the water flow, significantly reducing the direct scouring force of the water flow on the slope surface, while ensuring that the water flows smoothly into the drainage chamber, preventing water accumulation from damaging the slope 1. The permeable layer 4, protective net layer 5, planting soil layer 6, and vegetation layer 7 form an efficient soil conservation system that allows water infiltration while effectively blocking soil loss, and provides a good growth substrate for vegetation, enhancing the soil and water conservation effect. The application of spring dampers 10 can buffer the impact force of the water flow and slow down the water flow speed.

[0036] The working principle of the above embodiment is as follows: First, rainwater or water flow enters the drainage cavity inside the slope 1 through the permeable holes 2 on the right side of the slope 1. These permeable holes 2 are ingeniously designed to effectively guide the water flow and avoid direct erosion of the slope surface. After entering the drainage cavity, the water flow is blocked by the load-bearing walls 3. These load-bearing walls 3 not only enhance the structural stability of the slope 1, but also maintain a balanced water level inside the drainage cavity through the connecting grooves 12 at the bottom of their front side, ensuring uniform drainage. On the upper surface of the slope 1, the permeable layer 4 allows water to permeate and initially filters impurities while preventing soil erosion. The protective mesh layer 5 further prevents soil erosion. The sloping gravel provides a stable foundation for the planting soil layer 6 below. The planting soil layer 6 is rich in nutrients and provides a growth substrate for the plants in the vegetation layer 7. The plants in the vegetation layer 7, such as vetiver, penetrate deep into the soil through their extensive root systems, fixing soil particles and significantly enhancing the soil's stability and erosion resistance. When the water flow impacts the slope, the water-retaining plate 9 automatically flips over. Its right-flipping arc design at the top effectively slows down the water flow speed and reduces the erosion force of the water flow on the slope. At the same time, the spring damper 10 between the water-retaining plate 9 and the slope 1 absorbs and buffers the impact force of the water flow, further protecting the structure of the slope 1.
