[0002] Soil erosion is a significant issue in ecological environment management, especially in mountainous and slope engineering areas. Rainwater erosion can easily cause landslides and soil erosion, which not only damage the ecological environment but also pose safety hazards to surrounding buildings, roads, and other infrastructure. Currently, most soil and water conservation devices on the market are based on a single soil stabilization or drainage structure, which has a limited protective effect and cannot meet the multiple needs of soil stabilization stability, rainwater regulation and ecological restoration. Therefore, a soil and water conservation device was designed to solve the above problems. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides a soil and water conservation device that can stabilize and anchor the main body of a slope, effectively disperse soil and water loss stress, and simultaneously construct a vegetation growth substrate, enabling automatic collection, filtration, storage, and cyclic irrigation of rainwater. This forms an integrated solution encompassing engineering protection, ecological restoration, and resource recycling.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a soil and water conservation device, comprising a slope stabilization support structure, wherein the slope stabilization support structure is installed on the surface of the slope soil, and the surface of the slope stabilization support structure is further provided with a vegetation cultivation structure and a rainwater recycling structure. The slope stabilization support structure includes steel support joists and gabion cages. The steel support joists are arranged in a mesh pattern to form reinforcement grooves. The gabion cages are fixed to the inner wall of the reinforcement grooves. Several fixed anchor rods are fixedly connected to the lower surface of the steel support joists. The steel support joists are fixedly connected to the slope soil through the fixed anchor rods.

[0007] As a preferred embodiment of the soil and water conservation device of the present invention, the vegetation cultivation structure includes a planting trough and a nutrient substrate layer. The reinforcement trough is formed by the steel supporting keel being distributed in an alternating and staggered manner, and the nutrient substrate layer is laid inside the planting trough.

[0008] As a preferred embodiment of the soil and water conservation device of the present invention, the rainwater recycling structure includes a guide channel, a water storage chamber, and a water inlet. The guide channel is arranged along the longitudinal and transverse directions of the steel support keel. The water storage chamber is located on the lower side of the steel support keel. The water inlet is located on the surface of the water storage chamber and is connected to the guide channel. A filter grid is also fixedly connected to the opening of the water inlet.

[0009] As a preferred embodiment of the soil and water conservation device of the present invention, a plurality of water pumps are installed on the top of the water storage chamber. The input end of the water pump is fixedly connected to a water inlet pipe, which penetrates the surface of the water storage chamber and extends into the interior of the water storage chamber. The output end of the water pump is fixedly connected to a water delivery pipe, and the end of the water delivery pipe away from the water pump extends to the top of the planting trough and is equipped with a nozzle that matches the number of planting troughs.

[0013] Compared with the prior art, the beneficial effects of the present invention are: The device uses a steel support keel as its core frame, combined with gabion cages and an anchoring system, to form a stable and reliable slope stabilization foundation. This effectively resists soil erosion and prevents the slippage and loss of surface soil. The integrated vegetation cultivation structure on its surface utilizes the existing structural space as planting troughs and is filled with a special nutrient substrate, providing an excellent growth carrier for plants. This promotes ecological restoration and slope greening, achieving an organic combination of engineering protection and natural ecology. The rainwater harvesting and recycling system enables autonomous collection and efficient utilization of water resources. Through diversion, filtration, storage, and intelligent irrigation, it ensures a continuous water supply for vegetation, especially during the dry season, significantly improving the self-sustaining capacity and water resource utilization efficiency of the entire system.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1 like Figures 1 to 4 As shown: A soil and water conservation device includes a slope stabilization support structure 1, which is installed on the surface of the slope soil. The surface of the slope stabilization support structure 1 is also provided with a vegetation cultivation structure 2 and a rainwater recycling structure 3. The slope stabilization support structure 1 includes steel support joists 11 and gabion cages 13. The steel support joists 11 are arranged in a mesh pattern to form a reinforcement groove 12. The gabion cages 13 are fixed to the inner wall of the reinforcement groove 12. Several fixed anchor rods 14 are fixedly connected to the lower surface of the steel support joists 11. The steel support joists 11 are fixedly connected to the slope soil through the fixed anchor rods 14.

[0017] In this implementation plan: the steel support keel 11 serves as the basic load-bearing and connecting frame of the entire device. The reinforcement groove 12, formed by the mesh interlacing design, provides an installation carrier for the gabion cage 13. After the gabion cage 13 is arranged in close contact with the reinforcement groove 12, the steel support keel 11 is anchored in the slope soil by the fixed anchor rod 14 to achieve a firm connection between the device and the slope soil. At the same time, the vegetation cultivation structure 2 and the rainwater recycling structure 3 are arranged on the surface of the slope soil stabilization support structure 1.

[0018] Furthermore: like Figures 1 to 4 As shown: In an optional embodiment, reinforcing ribs 15 are also fixedly connected at the intersecting nodes of the steel support keel 11.

[0019] In this embodiment: the mesh-like staggered nodes of the steel support keel 11 are key locations for stress concentration. The settlement of the slope soil and the erosion of rainwater will cause the nodes to bear large lateral and longitudinal stresses. By adding reinforcing ribs 15 at this location, the concentrated stress at the node can be dispersed to the overall frame of the steel support keel 11, thereby enhancing the structural strength and deformation resistance of the node.

[0020] Furthermore: like Figures 1 to 4 As shown: In an optional embodiment, the outer surface of the steel support keel 11 is coated with an anti-corrosion and anti-rust coating, and the interior of the gabion cage 13 is filled with graded stone.

[0021] In this embodiment: both the steel support keel 11 and the gabion cage 13 are metal components. They are prone to rust when exposed to rainwater and soil corrosion media on outdoor slopes for a long time. Spraying an anti-corrosion and anti-rust coating can form an isolation layer on the metal surface to prevent the corrosive media from contacting the metal. The gabion cage 13 is a hollow mesh structure. After being filled with graded stones, the weight and interlocking properties of the stones are used to fill the gaps inside the cage, thereby improving the structural rigidity and soil stabilization effect of the gabion cage 13.

[0022] Furthermore: like Figures 1 to 4 As shown: In an optional embodiment, the vegetation cultivation structure 2 includes a planting trough 21 and a nutrient substrate layer 22. The reinforcement trough 12 is formed by steel support keels 11 arranged in an alternating pattern. The nutrient substrate layer 22 is laid inside the planting trough 21.

[0023] In this embodiment, the reinforcement groove 12 formed by the steel support keel 11 itself is used as the planting trough 21 for vegetation cultivation. There is no need to make and install an independent cultivation trough. The staggered distribution characteristics of the reinforcement groove 12 are adapted to the sloping terrain. A nutrient substrate layer 22 is laid inside the planting trough 21 to provide sufficient nutrients and growth carrier for the growth of soil-stabilized vegetation.

[0024] Furthermore: like Figures 1 to 4 As shown: In an optional embodiment, the rainwater recycling structure 3 includes a guide channel 31, a water storage chamber 32, and an inlet 33. The guide channel 31 is arranged along the longitudinal and transverse directions of the steel support keel 11. The water storage chamber 32 is opened on the lower side of the steel support keel 11. The inlet 33 is opened on the surface of the water storage chamber 32 and is connected to the guide channel 31. A filter grid 34 is also fixedly connected to the opening of the inlet 33.

[0025] In this implementation plan: the guide channels 31 arranged longitudinally and transversely along the steel support keel 11 are used to collect rainwater runoff from the slope. After the rainwater is collected in the guide channels 31, it flows into the water storage chamber 32 through the inlet 33 on the surface of the water storage chamber 32 for storage. The filter grid 34 at the inlet 33 can filter impurities such as mud, fallen leaves, and stones in the rainwater to prevent impurities from entering the water storage chamber 32 and causing internal blockage. The water storage chamber 32 is opened on the lower side of the steel support keel 11 and is arranged in close contact with the slope soil, making full use of the slope space and using the slope soil to protect the water storage chamber 32.

[0026] Furthermore: like Figures 1 to 4 As shown: In an optional embodiment, a plurality of water pumps 35 are installed on the top of the water storage chamber 32. The input end of the water pump 35 is fixedly connected to a water inlet pipe 36, which penetrates the surface of the water storage chamber 32 and extends into the interior of the water storage chamber 32. The output end of the water pump 35 is fixedly connected to a water delivery pipe 37, and the end of the water delivery pipe 37 away from the water pump 35 extends to the top of the planting trough 21 and is equipped with a number of nozzles 38 that are compatible with the number of planting troughs 21.

[0027] In this embodiment: a water pump 35 is used as a power source to draw rainwater stored in the water storage chamber 32 into the water delivery pipe 37 through the water inlet pipe 36. The water delivery pipe 37 delivers the rainwater to the top of the planting trough 21. Finally, the rainwater is evenly sprayed onto the nutrient substrate layer 22 inside the planting trough 21 through the nozzles 38 that are matched with the number of planting troughs 21, so as to realize the targeted supply and recycling of rainwater resources for vegetation cultivation.

[0028] Furthermore: like Figures 1 to 4 As shown: In an optional embodiment, the surface of the water pipe 37 is fitted with a plurality of clamps 39, which are fixedly connected to the steel support keel 11.

[0029] In this embodiment: the water pipe 37 is fixed to the surface of the steel support keel 11 by the clamping action of the clamp 39. The lateral and longitudinal displacement of the water pipe 37 is restricted by the interval fixation of multiple clamps 39.

[0030] Furthermore: like Figures 1 to 4 As shown: In an optional embodiment, a water level sensor 310 is installed inside the water storage chamber 32, and the water level sensor 310 is electrically connected to the water pump 35.

[0031] In this embodiment: the water level sensor 310 monitors the rainwater level inside the water storage chamber 32 in real time and converts the water level signal into an electrical signal and transmits it to the water pump 35. When the water level in the water storage chamber 32 is lower than the preset value, the water level sensor 310 sends a signal to control the water pump 35 to stop working, preventing the water pump 35 from running dry. When the water level in the water storage chamber 32 reaches the preset value, the water level sensor 310 sends a signal to control the water pump 35 to start working, supplying water to the planting trough 21, thereby realizing the automatic start and stop control of the water pump 35.

[0032] Furthermore: like Figures 1 to 4 As shown: In an optional embodiment, a retaining wall 16 is fixedly connected to the upper surface of the water storage cavity 32.

[0033] In this embodiment, the retaining wall 16 is set on the upper surface of the water storage cavity 32. Relying on its own structural strength, it prevents the soil above the slope from sliding down to the junction of the water storage cavity 32 and the steel support keel 11. At the same time, it prevents the accumulation of mud, sand and debris on the slope at the diversion channel 31 and the inlet 33, forming a protective barrier for the rainwater recycling structure 3.

[0034] Working principle: The steel support keel 11 serves as the foundation and connecting frame of the entire device. The reinforcement groove 12, formed by a mesh-like interlacing design, provides the installation carrier for the gabion cage 13. After the gabion cage 13 is arranged in close contact with the reinforcement groove 12, the steel support keel 11 is anchored into the slope soil using fixed anchor rods 14, achieving a firm connection between the device and the slope soil. Simultaneously, a vegetation cultivation structure 2 and a rainwater harvesting and recycling structure 3 are arranged on the surface of the slope stabilization support structure 1. The mesh-like interlacing nodes of the steel support keel 11 are designed to... At key locations where stress is concentrated, slope soil settlement and rainwater erosion can cause the nodes to bear significant lateral and longitudinal stresses. Adding reinforcing ribs 15 at these locations can disperse the concentrated stress at the nodes to the overall frame of the steel support keel 11, thereby enhancing the structural strength and deformation resistance of the nodes. Both the steel support keel 11 and the gabion cage 13 are metal components, which are prone to corrosion when exposed to rainwater and soil corrosion media on outdoor slopes for a long time. Spraying an anti-corrosion and anti-rust coating can form an isolation layer on the metal surface, preventing the corrosive media from contacting the metal.The gabion cage 13 has a hollow mesh structure. After being filled with graded stones, the weight and interlocking properties of the stones fill the gaps inside the cage, improving the structural rigidity and soil stabilization effect of the gabion cage 13. The reinforcement grooves 12 formed by the steel support keel 11 serve as planting troughs 21 for vegetation cultivation, eliminating the need for additional construction and installation of separate cultivation troughs. The staggered distribution of the reinforcement grooves 12 adapts to the sloping terrain. A nutrient substrate layer 22 is laid inside the planting trough 21 to provide sufficient nutrients and a growth carrier for the growth of soil-stabilizing vegetation. The diversion channels 31, arranged longitudinally and transversely along the steel support keel 11, comprehensively collect slope water. Rainwater runoff from the surface is collected in the diversion channel 31 and then flows into the storage chamber 32 through the inlet 33 on the surface of the storage chamber 32 for storage. The filter grid 34 at the inlet 33 can filter impurities such as mud, fallen leaves, and stones in the rainwater to prevent impurities from entering the storage chamber 32 and causing internal blockage. The storage chamber 32 is located on the lower side of the steel support keel 11 and is arranged in close contact with the slope soil, making full use of the slope space and using the slope soil to protect the storage chamber 32. Using the water pump 35 as the power source, the rainwater stored in the storage chamber 32 is pumped into the water delivery pipe 37 through the inlet pipe 36. The water delivery pipe 37 then... Rainwater is transported to the top of the planting trough 21, and finally sprayed evenly onto the nutrient substrate layer 22 inside the planting trough 21 through nozzles 38 that are matched with the number of planting troughs 21. This achieves targeted supply and recycling of rainwater resources for vegetation cultivation. The water supply pipe 37 is fixed to the surface of the steel support keel 11 by the clamping action of clamps 39. The lateral and longitudinal displacement of the water supply pipe 37 is restricted by the spacing of multiple clamps 39. The water level sensor 310 monitors the rainwater level inside the water storage chamber 32 in real time and converts the water level signal into an electrical signal and transmits it to the water pump 35. When the water level in the water storage chamber 32 is lower than the preset value, the water pump 35 will release the water. When the water level reaches a preset value, the water level sensor 310 sends a signal to control the water pump 35 to stop working, preventing the water pump 35 from running dry. When the water level in the water storage chamber 32 reaches a preset value, the water level sensor 310 sends a signal to control the water pump 35 to start working, supplying water to the planting trough 21, thus realizing automatic start and stop control of the water pump 35. The retaining wall 16 is set on the upper surface of the water storage chamber 32. Relying on its own structural strength, it prevents the soil above the slope from sliding down to the junction of the water storage chamber 32 and the steel support keel 11. At the same time, it prevents the accumulation of mud, sand and debris on the slope at the diversion channel 31 and the inlet 33, forming a protective barrier for the rainwater recycling structure 3.
