Description

Technical Field

[0001] This application relates to the field of soil and water conservation technology, specifically a soil and water conservation interception device. Background Technology

[0002] In the field of landscape design, landscape slopes, as a specialized treatment for areas with significant variations in terrain elevation, aim to balance aesthetics, practicality, and ecological sustainability. Through scientific topographical modification and functional layout, slope resources are fully integrated into the overall landscape system, while simultaneously meeting diverse needs such as pedestrian access and scenic appreciation. However, due to the inherent topographical characteristics of slopes, natural factors such as rainfall erosion and surface runoff can easily lead to soil erosion problems. This not only damages slope vegetation cover and landscape integrity but may also cause soil structural imbalance and even slope collapse, severely restricting the long-term stable use of landscape slopes. Therefore, effective prevention and control of soil erosion on landscape slopes has become a key issue in landscape engineering design and maintenance.

[0003] To address the aforementioned soil erosion problem, numerous technological studies and practices have been conducted in related fields. Among them, Chinese utility model patent with authorization announcement number CN221255511U discloses a landscape slope soil erosion interception device. This technical solution achieves rapid deployment of the interception net by setting up an anti-erosion device, which can effectively block soil erosion on the main body of the slope, significantly improving the safety and viewing period of the slope. At the same time, its matching collection device can quickly collect stones falling from the slope, preventing stones from rolling onto the road and posing a safety threat to vehicles, thus optimizing the construction and use effect of the landscape slope to a certain extent.

[0004] However, in practical applications, these anti-water and soil erosion devices are exposed to the outdoor environment for extended periods, continuously enduring multiple natural and environmental factors such as sun and rain, strong ultraviolet radiation, and erosion from silt and sand. Under these conditions, the materials of the device are prone to aging and embrittlement, and some metal components may even experience corrosion. This leads to a significant decrease in the overall structural strength of the device, which not only shortens its service life but also directly affects its effectiveness in intercepting soil and water erosion and its long-term reliability and safety.

[0005] Therefore, this application provides a soil and water conservation and interception device to solve the above problems. Utility Model Content

[0006] This application provides a soil erosion prevention and interception device, which aims to solve the problems mentioned in the background art, such as the erosion prevention components of existing landscape slope soil erosion interception devices being exposed to the outdoors for a long time and being susceptible to aging, embrittlement or corrosion due to the influence of the natural environment, resulting in reduced structural strength and shortened service life.

[0007] To achieve the above objectives, this application provides the following technical solution: a soil erosion control and interception device, comprising a slope body, an interception net laid on the slope body, and an anchoring mechanism for fixing the interception net to the slope body; the anchoring mechanism includes a spiral anchor for passing through the interception net and inserting into the ground, an anchor head fixedly connected to the upper end of the spiral anchor, an internal hexagonal groove formed at the upper end of the anchor head, and a washer rotatably fitted on the top of the spiral anchor; wherein, the surfaces of the spiral anchor, the anchor head, and the washer are all coated with a wear-resistant and corrosion-resistant coating. By burying the anchoring mechanism in the soil, the anti-aging, anti-corrosion, and anti-wear performance can be improved, avoiding damage to components due to natural environmental erosion during long-term outdoor use, extending the overall service life, and reducing maintenance and replacement costs; at the same time, it enhances the fixing effect of the anchoring mechanism on the interception net, the spiral anchor provides stronger pull-out force to prevent the interception net from shifting, ensuring the reliability of intercepting soil erosion on the slope body, the internal hexagonal groove can also improve the convenience of installation and disassembly, and the washer can prevent the interception net from being crushed.

[0008] Preferably, to improve the protective effect of the ground anchor head: the ground anchor head is fitted with a UV-resistant rubber cap, and the rubber cap has a slot for easy access. The UV-resistant rubber cap provides double protection for the ground anchor head, preventing UV radiation from causing aging of the ground anchor head, while also preventing rainwater and mud from entering the gaps of the ground anchor head, further enhancing its corrosion resistance and extending its service life.

[0009] Preferably, the gasket is conical in shape, and multiple insert rods are fixed at equal intervals in a ring at the bottom of the gasket. The conical gasket can increase the contact area with the main surface of the slope, disperse the pressure of the anchor head on the ground and the interception net, avoid ground subsidence or damage to the interception net, and at the same time guide the slope water flow to divert, reducing the impact of water flow on the anchoring mechanism.

[0010] Preferably, to facilitate the guiding and discharge of water flow: a drainage ditch is provided at the bottom of the main slope, and a ditch cover is provided at the top of the drainage ditch. The drainage ditch can guide and discharge water flow on the main slope in a directional manner, preventing water from accumulating at the bottom of the slope, reducing the soaking and erosion of the soil by accumulated water, and reducing the risk of soil erosion; the ditch cover can prevent stones, branches and other debris from falling into the drainage ditch and causing blockage, ensuring smooth drainage, while preventing pedestrians and vehicles from accidentally stepping into it, improving safety, and also providing preliminary filtration of fine silt in the water flow.

[0011] Preferably, to prevent the mesh on the trench cover from becoming clogged, the trench cover is installed at an angle, meaning the end of the trench cover closest to the intercepting mesh is lower than the end furthest from the intercepting mesh. This does not affect the protective function of the trench cover for the drainage ditch, effectively blocking large debris, and the water flow along the inclined cover is more stable, reducing the impact on the cover and the drainage ditch.

[0012] Preferably, to facilitate sediment interception: a groove is provided at the bottom of the slope body between the drainage ditch and the interception net, and a collection box is embedded in the groove. Both ends of the collection box are fixedly connected to handles. This allows for secondary collection of sediment that continues to flow with the water after being intercepted by the net, preventing sediment from entering the drainage ditch and causing siltation or overflowing onto the slope, further improving the effectiveness of soil and water conservation.

[0013] This application improves the anti-aging, anti-corrosion, and anti-wear properties by burying the anchoring mechanism in the soil, avoiding component damage caused by natural environmental erosion during long-term outdoor use, extending the overall service life, and reducing maintenance and replacement costs. At the same time, it enhances the fixing effect of the anchoring mechanism on the interception net, the spiral ground anchor provides stronger pull-out force to prevent the interception net from shifting, and ensures the reliability of intercepting soil and water loss on the main slope. The internal hexagonal groove also improves the convenience of installation and disassembly, and the gasket can prevent the interception net from being crushed.

[0014] The drainage ditch of this application can guide the flow of water on the main body of the slope to avoid water accumulation at the bottom of the slope, reduce the soaking and erosion of the main soil of the slope by the accumulated water, and reduce the risk of soil erosion; the ditch cover can prevent stones, branches and other debris from falling into the drainage ditch and causing blockage, ensuring smooth drainage, while preventing pedestrians and vehicles from accidentally stepping into it, improving the safety of use, and can also perform preliminary filtration of fine silt in the water flow.

[0017] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] Example 1 This embodiment provides a soil and water conservation and interception device, such as... Figure 1-4 As shown, the interception device includes a slope body 1, an interception net 2 laid on the slope body 1, and an anchoring mechanism 3 for fixing the interception net 2 to the slope body 1. The anchoring mechanism 3 includes a spiral anchor 31 for passing through the interception net 2 and inserting into the ground, an anchor head 32 fixedly connected to the upper end of the spiral anchor 31, an internal hexagonal groove 33 opened on the upper end of the anchor head 32, and a washer 34 rotatably sleeved on the top of the spiral anchor 31. The surfaces of the spiral anchor 31, the anchor head 32, and the washer 34 are all coated with a wear-resistant and corrosion-resistant coating. By burying the anchoring mechanism 3 into the soil, the anti-aging, anti-corrosion and anti-wear performance can be improved, avoiding damage to components caused by natural environmental erosion during long-term outdoor use, extending the overall service life and reducing maintenance and replacement costs; at the same time, the anchoring mechanism 3 enhances the fixing effect on the interception net 2, the spiral ground anchor 31 provides stronger pull force to prevent the interception net 2 from shifting, and ensures the reliability of intercepting soil and water loss on the main body of the slope 1. The internal hexagonal groove 33 can also improve the convenience of installation and disassembly, and the gasket 34 can prevent the interception net 2 from being crushed. During installation, a tool is inserted into the hexagonal groove 33 of the ground anchor head 32 and rotated, causing the spiral ground anchor 31 to rotate and insert into the ground of the slope body 1. The spiral ground anchor 31 penetrates deep into the stable soil layer, and the gasket 34 is pressed down and tightly adheres to the interception net 2 and the surface of the slope body 1. The spiral structure of the spiral ground anchor 31 interlocks with the soil to form a strong fixing force. The wear-resistant and anti-corrosion coating on the surfaces of the spiral ground anchor 31, ground anchor head 32 and gasket 34 can isolate rainwater, ultraviolet rays, silt and other corrosive substances, and slow down the aging and corrosion of the components. During use, the interception net 2 prevents the loss of soil particles from the slope body 1, and the anchoring mechanism 3 maintains the stability of the interception net 2 to ensure the continuous effectiveness of the interception function.

[0019] To enhance the protective effect of the ground anchor head 32, an ultraviolet-resistant rubber cap 321 is fitted onto the ground anchor head 32, and a convenient access groove 3211 is provided on the rubber cap 321. The ultraviolet-resistant rubber cap 321 provides double protection for the ground anchor head 32, preventing ultraviolet radiation from causing aging of the ground anchor head 32, while also preventing rainwater and mud from entering the gaps of the ground anchor head 32, further enhancing its corrosion resistance and extending its service life. The convenient access groove 3211 allows workers to quickly remove the rubber cap 321, facilitating operation of the ground anchor head 32 and the internal hexagonal groove 33, improving maintenance and installation efficiency. The rubber cap 321 is directly placed on the outside of the ground anchor head 32. The elasticity of the rubber cap 321 tightly wraps the ground anchor head 32. Its UV-resistant material blocks the direct exposure of ultraviolet rays to the ground anchor head 32, while also preventing rainwater and mud from contacting the surface and connection parts of the ground anchor head 32. When it is necessary to operate the ground anchor head 32, the staff can use the easy-access slot 3211 to apply force with tools or fingers to remove the rubber cap 321. After the operation is completed, it can be put back on to restore the protective state.

[0020] The gasket 34 is conical in shape, and multiple insert rods 341 are fixed at equal intervals in a ring at the bottom of the gasket 34. The conical gasket 34 can increase the contact area with the ground of the slope body 1, disperse the pressure of the ground anchor head 32 on the ground and the interception net 2, avoid ground subsidence or damage to the interception net 2, and guide the slope water flow to divert, reducing the impact of water flow on the anchoring mechanism 3; the multiple insert rods 341 can enhance the connection stability between the gasket 34 and the ground, prevent the gasket 34 from shifting or rotating, indirectly improve the fixing effect of the anchoring mechanism 3 on the interception net 2, and ensure the overall stability of the device. When installing the anchoring mechanism 3, as the spiral anchor 31 penetrates deeper into the ground, the conical pad 34 gradually approaches the ground surface of the slope body 1. The insertion rod 341 at its bottom is simultaneously inserted into the soil under pressure, forming multi-point fixation. During use, the conical pad 34 evenly transmits the pressure of the anchor head 32 to the ground, avoiding excessive local pressure. When water flows across the slope, the conical surface guides the water flow to both sides, reducing water impact. The engagement of the insertion rod 341 with the soil restricts the movement of the pad 34, maintaining its stability. The cooperation between the insertion rod 341 and the pad 34 prevents the intercepting net 2 from detaching from the anchoring mechanism 3.

[0021] To facilitate the guiding and discharge of water flow, a drainage ditch 11 is provided at the bottom of the main slope 1, and a ditch cover 4 is installed on the top of the drainage ditch 11. The drainage ditch 11 can guide and discharge the water flow on the main slope 1 in a directional manner, preventing water from accumulating at the bottom of the slope, reducing the soaking and erosion of the soil of the main slope 1 by accumulated water, and reducing the risk of soil erosion; the ditch cover 4 can prevent stones, branches and other debris from falling into the drainage ditch 11 and causing blockage, ensuring smooth drainage, while preventing pedestrians and vehicles from accidentally stepping into it, improving safety, and can also perform preliminary filtration of fine silt in the water flow. When precipitation or surface runoff occurs on the main slope 1, the water flows down the slope under the action of gravity and eventually collects in the drainage ditch 11 at the bottom of the main slope 1. The water is then directed to the designated discharge area through the channel of the drainage ditch 11. The ditch cover 4 covers the top of the drainage ditch 11. Its grid structure allows water and fine silt to pass through, while blocking large debris from entering the drainage ditch 11, thus avoiding channel blockage and ensuring the normal operation of the drainage function.

[0022] To prevent the mesh on the trench cover 4 from becoming clogged, the trench cover 4 is installed at an angle, meaning that the end of the trench cover 4 closest to the intercepting net 2 is lower than the end furthest from the intercepting net 2. The gravity difference created by the angle of inclination causes mud, sand, fallen leaves, and other debris accumulated on the mesh of the trench cover 4 to slide automatically to the higher end, preventing debris from clogging the mesh, ensuring smooth drainage of the trench cover 4, reducing the frequency of manual cleaning, and lowering maintenance workload. At the same time, it does not affect the protective function of the trench cover 4 for the drainage ditch 11, still effectively blocking large debris, and the water flow along the inclined cover is more stable, reducing the impact on the cover and the drainage ditch 11. The trench cover 4 is installed with the end closer to the intercepting net 2 lower and the end farther away from the intercepting net 2 higher, so that the surface of the cover plate forms an inclined slope. When the water flow carries mud, sand, fallen leaves and other debris to the trench cover 4, some of the water flow and fine mud and sand enter the drainage ditch 11 through the mesh. The debris that cannot pass through slides to the higher end away from the intercepting net 2 under the action of gravity due to the inclination of the cover plate, and eventually falls off the edge of the cover plate, avoiding the accumulation of debris and clogging the mesh, and ensuring that the water flow continuously enters the drainage ditch 11 through the cover plate.

[0023] To facilitate sediment interception, a groove 12 is provided at the bottom of the slope body 1 between the drainage ditch 11 and the interception net 2. A collection box 5 is embedded in the groove 12, and handles 51 are fixedly connected to both ends of the collection box 5. This allows for secondary collection of sediment that is still flowing with the water after being intercepted by the interception net 2, preventing sediment from entering the drainage ditch 11 and causing siltation or overflowing onto the slope, thus further improving the effectiveness of soil and water conservation. The collection box 5 is embedded in the groove 12, which does not affect the aesthetics and accessibility of the slope body 1, and the groove 12 can fix the position of the collection box 5 to prevent displacement. The handles 51 make it easy for staff to quickly remove the collection box 5 to clean the sediment, making operation convenient and reducing maintenance difficulty. The top of the collection box 5 is flush with the surface of the main body of the slope 1. When the water flows down carrying a small amount of mud and sand that is not blocked by the interception net 2, it flows into the collection box 5 in the groove 12. The mud and sand settle and accumulate in the collection box 5, while the water flows out from the gaps or edges of the collection box 5 into the drainage ditch 11. When the mud and sand in the collection box 5 accumulate to a certain amount, the staff holds the handle 51 to remove the collection box 5 from the groove 12, pours out the mud and sand, and puts it back to restore the mud and sand collection function.
