Description

Technical Field

[0001] This utility model relates to the field of soil and water conservation devices, specifically to a slope protection structure for soil and water conservation. Background Technology

[0002] Soil and water conservation is a crucial task in preventing soil erosion, protecting and improving soil and water resources, and building a sound ecological environment. Its core objective is to conserve water resources, reduce surface runoff, and prevent soil erosion through comprehensive technical measures. As a high-risk area for soil erosion, the rationality of slope protection structures directly affects the effectiveness of soil and water conservation and the safety of surrounding facilities. Slope protection structures intercept sediment and divert water flow, preventing landslides and rockfalls, thereby protecting roads, buildings, and the ecological environment.

[0003] In existing technologies, some slope protection structures use protective nets to directly cover the slope, relying on the physical barrier effect of the nets to prevent soil and rock loss. However, such structures lack effective flow guidance design. During rainy days, rainwater flows freely on the slope surface, which not only impacts the slope soil and causes it to soften, but also carries mud and sand out through the gaps in the protective nets. Over the long term, this can easily lead to landslide accidents.

[0004] While other slope protection structures incorporate simple diversion channels, they only address surface runoff and neglect the collection of rainwater at the slope crest. However, in reality, rainwater collects at the crest, forming initial runoff. Due to the height difference between the crest and surface, the water accumulates potential energy as it flows down the slope, increasing scouring force. Furthermore, the soil at the crest remains waterlogged, leading to saturation and increased weight, potentially triggering a chain reaction of slope collapse rather than a localized landslide. The extent and severity of this damage far exceed that of localized surface erosion. Therefore, to address the shortcomings of existing technologies, it is necessary to design a slope protection structure that considers both surface and crest runoff diversion. Utility Model Content

[0005] The present invention aims to provide a slope protection structure for soil and water conservation, and to design a slope protection structure that takes into account both the slope surface and the top of the slope for drainage.

[0006] To achieve the above objectives, this application provides the following technical solution: A slope protection structure for soil and water conservation includes a frame, a mesh body fixedly connected to the frame, a water guide shell fixedly connected to the top of the frame, water guide pipes fixedly connected to both sides of the water guide shell, and a filter screen installed inside the water guide shell; the side of the mesh body away from the slope body is provided with a plurality of flow channels fixedly connected to the frame, the flow channels extending along the slope surface, and the side wall of the water guide shell below the filter screen is provided with a plurality of overflow ports facing the flow channels.

[0007] The working principle and beneficial effects of this utility model: In this application, the frame provides support for the overall structure, the mesh body physically intercepts loose soil and rocks on the slope, the water guide shell is fixed to the top of the frame and is specifically used to collect rainwater from the top of the slope, the filter screen intercepts large particles of debris in the rainwater to avoid clogging the water guide pipes and overflow outlets, the water guide pipes on both sides of the water guide shell serve as the main drainage channels for rainwater from the top of the slope, directly draining the regular water volume; the diversion channel on the side of the mesh body away from the slope extends along the slope surface to receive rainwater falling on the slope surface, and when the water level in the water guide shell exceeds the limit, the excess rainwater will be discharged into the diversion channel through the overflow outlet for responsible external discharge.

[0008] This application achieves centralized control of rainwater at the top of the slope, preventing water accumulation at the top of the slope from causing soil saturation and collapse. It also diverts rainwater from the slope surface through diversion channels, weakening the potential energy and scouring force of the water flow, reducing sediment loss, fundamentally reducing the risk of slope landslides, and protecting the safety of surrounding facilities.

[0009] Furthermore, the overflow outlet is higher than the inlet of the water pipe. This higher overflow outlet height ensures that rainwater inside the water pipe casing is preferentially discharged through the water pipe.

[0010] Furthermore, a baffle is fixed to the top of the water guide shell, and the baffle extends away from the slope. The baffle extends away from the slope to prevent rainwater from overflowing from the edge of the slope top, while guiding the rainwater scattered on the slope top to collect inside the water guide shell.

[0011] Furthermore, the water guide pipe extends outward along the width direction of the frame.

[0012] Furthermore, the bottom of the diversion channel is inclined along the slope of the slope, and the slope of the channel bottom is adapted to the slope of the slope. Gravity drives the rainwater in the channel to flow quickly down the slope, preventing rainwater from stagnating or overflowing. Attached Figure Description

[0015] The following detailed description illustrates the specific implementation method: Example: A slope protection structure for soil and water conservation, such as Figure 2 As shown, this includes a frame 2 made of high-strength aluminum alloy, with its four corners fixed to the surface rock of the slope using anchor bolts. Figure 1 As shown, it also includes a mesh body 1, which is woven from galvanized steel wire and its edges are welded and fixed to the inner wall of the frame 2 to achieve physical interception of loose soil and rocks on the slope.

[0016] like Figure 3 As shown, it also includes a water guide shell 6, which is a hollow rectangular stainless steel structure. The bottom is welded to the top of the frame 2. The upper part of the interior is detachably installed with a stainless steel filter screen 7 by bolts. The lower part of the two side walls is respectively fixedly connected to a PVC water guide pipe 3. The water guide pipe 3 extends outward along the width of the frame 2, and the water outlet is directed towards the pre-set drainage area (such as a drainage ditch or drainage channel) on the outside of the slope foot.

[0017] like Figure 4 As shown, the water guide shell 6 has several rectangular overflow ports 8 on its two side walls below the filter screen 7. The frame 2 is fixed with guide grooves 4 that correspond one-to-one with the number of overflow ports 8. The guide grooves 4 are U-shaped plastic grooves that are evenly distributed along the length of the frame 2. The top end corresponds to the side wall of the water guide shell 6, and the bottom end extends to the bottom edge of the frame 2. A stainless steel baffle 5 extending away from the slope is welded to the top of the water guide shell 6.

[0018] In practical applications, during normal rainfall (regular rainfall), rainwater at the top of the slope is blocked and guided by the baffle 5 and flows into the water guide shell 6. After being intercepted by the filter screen 7, large particles such as leaves and stones are intercepted and then flow into the water guide pipes 3 on both sides. Finally, the water flows outward through the water guide pipes 3 and into the drainage ditch on the outside of the slope foot. At the same time, rainwater falling on the slope surface falls directly into the diversion channel 4 and flows rapidly under the action of gravity, eventually flowing into the drainage ditch as well.

[0019] When excessive rainfall causes the water level inside the water-conducting shell 6 to rise to the height of the overflow outlet 8, the excess rainwater flows into the corresponding diversion channel 4 through the overflow outlet 8, flowing along the channel together with the newly added rainwater on the slope. The drainage ditch is connected to the municipal drainage network for centralized discharge or diverted into an ecological storage tank for recycling, completely preventing rainwater from accumulating around the slope. The filter screen 7 only needs to be cleaned manually on a regular basis.

[0020] It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
