Description

Technical Field

[0001] This utility model relates to the technical field of soil and water conservation devices, and in particular to an ecological slope protection system for soil and water conservation. Background Technology

[0002] In fields such as water conservancy projects, highway and railway slope protection, and mine ecological restoration, slope soil erosion and structural instability have always been core issues that urgently need to be addressed. Traditional slope protection techniques often employ single hard protection or simple vegetation cover, which have obvious limitations: while hard protection can resist rainwater erosion in the short term, it has poor ecological properties, disrupts the natural ecological cycle of the slope, and cannot adapt to slight slope deformation, easily leading to cracks and protection failure; simple vegetation slope protection, due to the lack of stable structural support and scientific water management system, is prone to slope soil erosion, exposed vegetation roots, and even landslides and collapses under heavy rainfall conditions. At the same time, vegetation withers easily due to lack of water during the dry season, making it difficult to achieve long-term soil and water conservation effects.

[0003] A search revealed Chinese Patent Publication No. CN212129173U, which discloses an ecological slope protection method for soil and water conservation. The method includes a slope body, a gravel layer at the left end of the slope body, an ecological concrete layer on top of the gravel layer, a soil layer on top of the ecological concrete, a cement layer on top of the soil layer, and multiple water pipes evenly distributed on the cement layer. These water pipes are covered with a vegetation layer, and the bottom ends of the water pipes are connected to a discharge pipe. A receiving plate is located at the bottom left end of the slope body, and the bottom end of the discharge pipe contacts the top end of the receiving plate. The bottom ends of the gravel layer, ecological concrete layer, soil layer, cement layer, and vegetation layer are all connected to the top end of the receiving plate. This facilitates rainwater drainage, reduces the impact on the slope body, and improves the ecological slope protection. However, it still suffers from problems such as a lack of water-retaining substrate structure, inability to store water to ensure long-term vegetation growth, and overall deficiencies in the comprehensiveness of soil and water conservation. Utility Model Content

[0004] The purpose of this utility model is to provide an ecological slope protection system for soil and water conservation, in order to solve the problem that the existing technology lacks a water-retaining substrate structure, cannot store water to ensure the long-term growth of vegetation, and is therefore lacking in the overall comprehensiveness of soil and water conservation.

[0005] To achieve the above objectives, a soil and water conservation ecological slope protection is provided, comprising a slope body, wherein a soil layer is connected to the lower end of the slope body, and a base layer is fixedly connected to the upper end of the soil layer; A support layer is laid horizontally on the upper end of the base layer, and a wire mesh is fixedly connected to the upper end of the support layer.

[0006] According to the aforementioned ecological slope protection method for soil and water conservation, a filter layer is horizontally laid at the upper end of the wire mesh, and a coarse sand pad layer is fixedly connected to the filter layer.

[0007] According to the aforementioned ecological slope protection method for soil and water conservation, a core drainage layer is horizontally laid on the coarse sand cushion layer, and several honeycomb frames are formed on the surface of the core drainage layer. A drainage pipe is fixedly connected to the lower end of the core drainage layer.

[0008] According to the aforementioned ecological slope protection method for soil and water conservation, a composite layer is horizontally laid on the upper end of the core drainage layer, and several square frames are opened on the composite layer, with water-retaining substrates placed inside the square frames.

[0009] According to the aforementioned ecological slope protection method for soil and water conservation, a surface planting layer is horizontally laid on the upper end of the composite layer, and several planting blocks are formed on the surface planting layer.

[0010] According to the aforementioned ecological slope protection method for soil and water conservation, a drainage ditch is constructed within the soil layer, and the upper end of the drainage ditch is fixedly connected to the lower end of a drainage pipe.

[0011] The above-mentioned solution has the following beneficial effects: 1. This patent forms an efficient drainage system by combining a honeycomb frame core drainage layer with a drainage pipe directly connected to a drainage ditch, which improves drainage efficiency during heavy rain and eliminates the risk of landslides due to water accumulation on slopes; the water-retaining substrate stores water in zones within the composite layer, extending the drought resistance period of plants and improving their survival rate; the wire mesh and support layer anchor deep into the slope, ensuring long-term structural stability.

[0012] 2. This patent uses a sand cushion layer and a filter layer to block the infiltration of silt and sand, reducing the frequency of drainage system maintenance; the modular layered structure supports segmented construction, and the direct connection structure of drainage pipes and channels prevents slope toe erosion, reducing maintenance costs.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-5 This utility model provides an ecological slope protection system for soil and water conservation, comprising a slope body 1, a soil layer 2 connected to the lower end of the slope body 1, and a base layer 16 fixedly connected to the upper end of the soil layer 2. A support layer 15 is laid horizontally on the upper end of the base layer 16, and a wire mesh 14 is fixedly connected to the upper end of the support layer 15. The base layer 16 provides basic support for the entire slope protection structure, ensuring the stability of subsequent layers and preventing the slope protection layer from shifting due to the loose structure of the slope body 1 itself. The support layer 15 further enhances the load-bearing capacity of the structure and disperses the loads from the upper layers and the external environment. The wire mesh 14, through its mesh structure, fixes the materials laid on top, preventing the materials from slipping or being lost during use. At the same time, it can also enhance the connection between the layers, improve the tensile and deformation resistance of the overall slope protection structure, ensure the stability of the slope protection structure from the basic level, and lay the foundation for the realization of subsequent soil and water conservation functions.

[0018] A filter layer 13 is horizontally laid on the upper end of the wire mesh 14. A coarse sand pad layer 12 is fixedly connected to the filter layer 13. When rainwater seeps into the filter layer 13, the filter layer 13 can effectively intercept larger particles of impurities carried in the water, preventing these impurities from entering the lower structural layer and causing blockage, thus ensuring the smooth flow of water infiltration channels. The filtered water continues to seep downwards into the coarse sand pad layer 12. The coarse sand pad layer 12 utilizes the gaps between its particles to play a secondary filtration role, further purifying the water and intercepting smaller particles of impurities. On the other hand, it can slow down the water infiltration rate, allowing the water to remain in the pad layer for a certain period of time, creating conditions for subsequent drainage and water retention.

[0019] A core drainage layer 7 is horizontally laid on a coarse sand cushion layer 12. Several honeycomb frames 8 are formed on the surface of the core drainage layer 7. A drainage pipe 3 is fixedly connected to the lower end of the core drainage layer 7. The core drainage layer 7 is a key drainage component of the entire slope protection structure. Its internal drainage channels allow water to quickly diffuse and collect inside the drainage layer after it seeps into it. The honeycomb frames 8 on the surface not only increase the surface area of ​​the core drainage layer 7 and improve its water carrying capacity, but also enhance the structural strength of the core drainage layer 7 through the stable shape of the honeycomb structure, preventing the drainage layer from collapsing under the impact of water flow and external pressure. The collected water flows along the internal channels of the core drainage layer 7 to the drainage pipe 3, and then is quickly discharged to the outside of the slope protection structure through the drainage pipe 3, effectively reducing water accumulation in the slope 1 and reducing the risk of landslides and collapses caused by excessive soil moisture content and increased soil weight due to water accumulation.

[0020] A core drainage layer 7 is horizontally laid on a coarse sand cushion layer 12. Several honeycomb frames 8 are formed on the surface of the core drainage layer 7. A drainage pipe 3 is fixedly connected to the lower end of the core drainage layer 7. The composite layer 10 has good air permeability and a certain load-bearing capacity, which can not only ensure the stable laying of the upper surface planting layer 9, but also provide a gas exchange channel between the lower core drainage layer 7 and the upper water-retaining substrate 6, meeting the oxygen demand of the plant roots. The frames 5 provide a fixed housing space for the water-retaining substrate 6, preventing the water-retaining substrate 6 from moving or being lost on the slope. This ensures that the water-retaining material is evenly distributed on the composite layer 10. The water-retaining substrate 6 has a strong water absorption and retention capacity. When rainwater falls on the slope, some of the rainwater will be absorbed and stored by the water-retaining substrate 6. In dry weather, the water-retaining substrate 6 can slowly release the stored water to provide a continuous water supply for the growth of vegetation in the planting layer 9 on the upper surface, effectively solving the problem of vegetation withering due to lack of water on the slope. At the same time, the water-retaining substrate 6 can also improve the water retention performance of the slope soil, enhance the ecological water retention effect of the slope protection structure, and promote the healthy growth of vegetation.

[0021] A surface planting layer 9 is horizontally laid on the upper end of the composite layer 10. Several planting blocks 4 are formed on the surface planting layer 9. The surface planting layer 9 is the direct carrier for vegetation growth. It contains rich organic matter and nutrients, which can provide the nutrients and attachment space required for plant roots to grow. The planting blocks 4 are reasonably divided according to the growth characteristics of different plants and the needs of slope protection, which facilitates the targeted selection and planting of plants with soil and water conservation functions. After planting, the plants form a root network in the surface planting layer 9 and the underlying structural layer through their root systems, which firmly fixes the slope soil and prevents soil erosion. At the same time, the stems and leaves of the plants can effectively intercept rainwater, slow down the impact speed of rainwater on the slope, reduce the generation of slope runoff, further reduce the risk of soil erosion, and the growth of vegetation can also improve the ecological environment of the slope, enhance the ecological benefits and landscape effect of the slope protection structure.

[0022] A drainage ditch 11 is constructed within the soil layer 2. The upper end of the drainage ditch 11 is fixedly connected to the lower end of the drainage pipe 3. After the drainage pipe 3 discharges the water collected in the core drainage layer 7, the water flows into the drainage ditch 11 through the connection between the lower end of the drainage pipe 3 and the drainage ditch 11. The drainage ditch 11 forms a dedicated drainage channel within the soil layer 2, which can quickly guide the water from the drainage pipe 3 to the designated drainage area outside the slope 1. Through the guiding effect of the drainage ditch 11, water can be effectively prevented from accumulating within the soil layer 2, preventing the soil layer 2 from softening and becoming unstable due to excessive moisture content, thus ensuring the structural stability of the soil layer 2 at the lower end of the slope 1.

[0023] Working principle: After rainwater seeps into the planting blocks 4 of the surface planting layer 9, it is absorbed and stored by the water-retaining substrate 6; excess water flows through the square frame 5 of the composite layer 10 and enters the core drainage layer 7. Its honeycomb frame 8 structure quickly disperses the water flow. After being filtered by the coarse sand cushion layer 12, the clean water is discharged through the drainage pipe 3 into the drainage ditch 11; at the same time, the wire mesh 14 and the support layer 15 anchor the deep soil of the slope 1, and the filter layer 13 blocks the infiltration of sediment, forming a synergistic mechanism of surface water storage and drought resistance, efficient drainage in the middle layer, and deep stability and anti-slip, realizing simultaneous water and soil retention and ecological restoration.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
