Description

Technical Field

[0001] The invention relates to the technical field of slope protection, and in particular to an ecological protection device for slope drainage and greening. Background Art

[0002] Slope greening aims to rebuild the vegetation ecosystem on exposed slopes caused by engineering construction, natural erosion and other reasons through artificial measures. Specifically, it is necessary to accurately select suitable plant species based on factors such as the geological conditions and climate characteristics of the slope. For example, in arid areas, drought-resistant sea buckthorn and caragana are often used; in humid areas, water-loving bermudagrass is preferred. With the help of greening spraying, laying ecological bags and other means, plant seeds, nutrient soil, etc. are sown or arranged on the slope.

[0003] However, the existing slope regreening structure has obvious shortcomings. Whenever it rains, especially when it rains suddenly, a large amount of rainwater will quickly accumulate on the slope surface. Due to the lack of effective drainage channels, rainwater cannot be discharged in time. This not only causes the slope runoff to increase sharply, but also directly and strongly scours the slope, taking away the fertile soil on the surface, causing the soil fertility to drop significantly, and thus seriously affecting the growth trend and survival rate of vegetation. Moreover, the continuous accumulation of water may continue to infiltrate into the slope, causing the soil water content to continue to rise, the soil saturation to increase accordingly, and the soil shear strength to significantly reduce, which greatly increases the risk of geological disasters such as landslides and mud-rock flows, and poses a serious threat to the surrounding buildings, roads and the safety of life and property of people.

[0004] In addition, in daily maintenance, watering is crucial to the effectiveness of slope regreening, but the existing slope regreening structure has significant defects in this regard. Due to the lack of a complete water storage and automatic irrigation system, each watering requires a lot of manpower. Maintenance personnel have to frequently travel between the water source and the slope, carrying or transporting a large amount of water, which is a cumbersome and inefficient process. If the slope area is large, the amount of water required will increase dramatically, and the workload of manual transportation and watering will increase exponentially, which not only increases labor costs, but also long-term watering work is likely to cause fatigue to maintenance personnel, thereby affecting the timeliness and comprehensiveness of watering. In addition, affected by factors such as weather and terrain, the implementation of manual watering is extremely difficult. In hot and hot weather, maintenance personnel work outdoors for a long time and face health risks such as heat stroke; in cold weather, the transportation and watering process of water may be hindered by ice. If the slope is steep and the terrain is complex, it will be difficult for personnel and equipment to reach, which means that the vegetation in some areas cannot be irrigated in a timely and effective manner, resulting in uneven vegetation growth in these areas, seriously affecting the overall greening effect and making it difficult to achieve stable recovery and sustainable development of the slope ecosystem.

[0029] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0030] Example 1

[0031] Please refer to Figure 1-Figure 6 The embodiment of the present application provides an ecological protection device for drainage and greening of a slope 1, comprising: a drainage ditch 2 arranged at the top of the above-mentioned slope 1; a drainage ditch 11 arranged at the bottom of the above-mentioned slope 1; a concrete support structure, comprising a concrete frame and concrete reinforcement piles 303, the above-mentioned concrete frame is arranged on the slope surface of the above-mentioned slope 1, and forms a plurality of rectangular planting areas with the slope surface of the above-mentioned slope 1, the plurality of the above-mentioned rectangular planting areas are respectively guided in the length direction and the width direction of the above-mentioned slope 1, and are distributed in a rectangular array, the above-mentioned concrete reinforcement piles 303 are arranged on the inner side of the above-mentioned concrete frame, and the end of the above-mentioned concrete reinforcement piles 303 away from the above-mentioned concrete frame extends into the interior of the above-mentioned slope 1; wherein any of the above-mentioned rectangular planting areas is provided with spraying material Layer 10, any of the above-mentioned rectangular planting areas is provided with a grid 4 for covering the surface of the above-mentioned spraying material layer 10; and an irrigation structure, including a water storage chamber 12, a first pumping structure, an irrigation chamber 8 and a second pumping structure, the above-mentioned water storage chamber 12 is arranged at the bottom of the above-mentioned slope 1, and the above-mentioned water storage chamber 12 is located below the above-mentioned drainage ditch 11, the above-mentioned first pumping structure is used to connect the above-mentioned drainage ditch 11 with the above-mentioned water storage chamber 12, the above-mentioned irrigation chamber 8 is arranged at the top of the above-mentioned concrete frame, and is arranged along the width direction of the slope surface of the above-mentioned slope 1, the bottom of the above-mentioned irrigation chamber 8 is provided with a drainage port for connecting the above-mentioned rectangular planting area, the above-mentioned drainage port is provided with a permeable layer 9, and the above-mentioned second pumping structure is used to connect the above-mentioned water storage chamber 12 with the above-mentioned irrigation chamber 8.

[0032] In terms of drainage, the ecological protection device of the present application has an intercepting ditch 2 located at the top of the slope 1, which can intercept water from the top of the slope to prevent it from scouring the slope surface; the drainage ditch 11 is located at the bottom to collect slope runoff. When it rains, rainwater converges to the drainage ditch 11 through the intercepting ditch 2 and is naturally discharged by the terrain. The concrete support structure stabilizes the slope 1 to prevent problems such as landslides caused by water scouring, which is conducive to the long-term stable operation of drainage. In terms of regreening, the concrete frame forms a plurality of rectangular planting areas on the slope surface, which are distributed in a rectangular array to provide a regular space for plant growth. The spraying material layer 10 contains plant seeds, nutrients, etc., and the mesh grille 4 covers the surface to prevent the material from being washed away by rainwater, which is conducive to the rooting and growth of seeds and the realization of slope vegetation coverage. From the perspective of water storage and irrigation, the water storage chamber 12 is located at the bottom of the slope 1 and below the drainage ditch 11. The first pumping structure connects the drainage ditch 11 with the water storage chamber 12, and can collect excess rainwater for storage. During drought, the second pumping structure pumps water from the water storage chamber 12 to the irrigation chamber 8. The irrigation chamber 8 is arranged along the width of the slope. The permeable layer 9 at the bottom drainage port can evenly and slowly infiltrate water into the rectangular planting area, accurately providing water to the plants and ensuring that the vegetation can grow healthily even during water shortage periods. The overall advantages of this device are obvious. It not only achieves efficient drainage and reduces the risks of soil erosion and geological disasters, but also increases the vegetation coverage rate and improves the ecological environment through reasonable greening design. At the same time, the water storage and irrigation function realizes the recycling of water resources, saves manpower and water resources, and ensures the sustainability of the ecological protection of the slope 1.

[0033] As a preferred embodiment, the opening of the drainage ditch 11 is paved with a panel brick 6, and the panel brick 6 is provided with a water-permeable hole.

[0034] In the above embodiment, the panel bricks 6 with water-permeable holes are laid at the opening of the drainage ditch 11, which has many significant advantages. From the drainage point of view, the water-permeable holes can allow the surface runoff of the slope 1 to flow smoothly into the drainage ditch 11, achieve efficient drainage, and avoid damage to the slope vegetation and soil structure due to water accumulation. At the same time, the panel bricks 6 can effectively prevent larger particles of mud and debris from entering the drainage ditch 11, reduce the risk of ditch blockage, and reduce the subsequent maintenance costs. In terms of the stability of the slope 1, the panel bricks 6 are laid at the opening, which is like adding a layer of solid protection to the drainage ditch 11, enhancing the anti-scouring ability of the edge of the drainage ditch 11, stabilizing the surrounding soil, and reducing the risk of local collapse of the slope 1 caused by water erosion. In addition, in terms of aesthetics and practicality, the laying of the panel bricks 6 makes the appearance of the drainage ditch 11 more neat and improves the overall landscape effect of the slope 1.

[0035] As a preferred embodiment, a filter screen 15 is provided at one end of the drainage ditch 11, and the drainage ditch 11 is divided into a first ditch body and a second ditch body, and the first pumping structure is connected to the second ditch body.

[0036] In the above embodiment, the filter 15 can effectively intercept leaves, mud, garbage and other debris in the water flow, prevent them from entering the second ditch body, avoid clogging the first pumping structure, ensure the stability and efficiency of the pumping process, and greatly reduce equipment failures and maintenance costs caused by debris blockage. The first ditch body serves as a debris sedimentation area, allowing larger particles in the water flow to settle first, further ensuring the cleanliness of the water flowing into the second ditch body. The second ditch body is connected to the first pumping structure, and can provide a relatively pure water source for the water storage chamber 12, ensuring the quality of water storage, preventing impurities from entering the water storage chamber 12, reducing the wear and clogging risks of equipment in subsequent irrigation structures, and overall improving the consistency and reliability of the drainage, water storage and irrigation functions in the slope 1 drainage and greening ecological protection device.

[0037] As a preferred embodiment, the concrete frame includes a plurality of concrete cross beams 301 and a plurality of concrete longitudinal beams 302, wherein the plurality of concrete cross beams 301 are arranged in parallel and at intervals along the length direction of the slope surface of the slope 1, and the plurality of concrete longitudinal beams 302 are arranged in parallel and at intervals along the width direction of the slope surface of the slope 1;

[0038] The plurality of concrete cross beams 301 and the plurality of concrete longitudinal beams 302 are alternately arranged on the slope 1 to form a plurality of rectangular planting areas.

[0039] In the above embodiment, the concrete frame composed of multiple concrete crossbeams 301 and concrete longitudinal beams 302 can effectively improve the stability of the slope 1. The concrete crossbeams 301 are arranged in parallel and spaced along the length direction of the slope, and the concrete longitudinal beams 302 are arranged in parallel and spaced along the width direction of the slope. The rectangular planting area formed on the slope 1 builds a stable structure, evenly disperses the slope pressure, strengthens the restraint on the soil, and prevents soil displacement and collapse caused by factors such as gravity and rain erosion. At the same time, it provides a regular space for plant planting, facilitates layout according to plant characteristics, and is conducive to scientific and systematic planting management. Moreover, the concrete frame itself has a blocking effect on slope runoff, which can slow down the water flow speed, reduce the risk of soil erosion, and maintain good soil conditions for plant growth. In addition, it also provides a solid foundation for the installation of greening structures such as the spraying material layer 10 and the mesh grid 4, ensuring the stable operation of all links of the slope 1 drainage and greening ecological protection device, and helping the long-term ecological restoration and protection of the slope 1.

[0040] As a preferred embodiment, the concrete frame further includes a reinforcing beam, and the reinforcing beam is disposed between any adjacent concrete cross beams 301 and between any adjacent concrete longitudinal beams 302 .

[0041] In the above embodiment, reinforcing beams are added to the concrete frame, which greatly improves the stability of the entire structure. The reinforcing beams between adjacent concrete cross beams 301 and longitudinal beams are like additional supporting skeletons, which can effectively disperse stress. When the slope 1 is affected by external forces such as rain erosion and gravity, the reinforcing beams can share the pressure borne by the cross beams and longitudinal beams to avoid deformation or damage due to excessive local force. This not only enhances the restraining ability of the concrete frame on the slope soil and reduces the risk of collapse of the slope 1, but also provides a more reliable boundary support for the rectangular planting area.

[0042] As a preferred embodiment, a waterproof film 7 is further provided inside the slope 1 .

[0043] In the above embodiment, when encountering rainy weather, the waterproof film 7 can prevent a large amount of rainwater from penetrating into the deep soil of the slope 1, prevent the shear strength from being reduced due to excessive water content of the soil, and thus reduce the risk of geological disasters such as landslides and mud-rock flows. This not only ensures the stability of the structure of the slope 1 itself, but also protects the safety of surrounding buildings, roads and personnel. Moreover, the waterproof film 7 can reduce the excessive loss of water in the soil, preserve a certain amount of water for plant growth during droughts, help maintain the normal growth of vegetation, and enhance the greening effect of the slope 1. In addition, the waterproof film 7 can also reduce the erosion of groundwater on the soil of the slope 1, extend the service life of the slope 1 protection facilities, and reduce the subsequent maintenance costs.

[0044] As a preferred embodiment, connecting pieces 5 are provided at the four corners of any of the above-mentioned grids 4, and the above-mentioned connecting pieces 5 are detachably provided on the above-mentioned concrete frame by bolts.

[0045] In the above embodiment, firstly, this detachable design greatly facilitates installation and subsequent maintenance. During installation, the staff can conveniently fix the mesh grille 4 in the designated position to improve construction efficiency; when the mesh grille 4 is damaged, aged or needs to be replaced, the bolts can be easily unscrewed, the damaged parts can be removed and replaced, without the need to dismantle other structures on a large scale. Secondly, the connecting piece 5 can ensure that the mesh grille 4 is firmly attached to the concrete frame, and when facing external forces such as rain erosion and strong winds, it can still firmly cover the surface of the spraying material layer 10, effectively preventing the spraying material from being dispersed, providing a stable environment for the rooting and germination of plant seeds, and ensuring the smooth progress of the slope 1 greening work.

[0046] Optionally, the slope surface of the slope 1 is covered with a slope protection net, which is used to cover multiple mesh grilles 4 at the same time.

[0047] As a preferred embodiment, the first pumping structure includes a first guide tube 16, a first pump body 17 and a second guide tube connected in sequence, the end of the first guide tube 16 away from the first pump body 17 is connected to the drainage ditch 11, and the end of the second guide tube away from the first pump body 17 is connected to the water storage chamber 12.

[0048] In the above embodiment, the first guide pipe 16 can effectively connect to the drainage ditch 11, stably introduce the water flow therein, and provide a reliable water source for subsequent pumping. The first pump body 17, as the core power source, can flexibly adjust the pumping force to adapt to different water volume and water level conditions to ensure efficient pumping. The second guide pipe is responsible for safely transporting the water pumped out by the first pump body 17 to the water storage chamber 12 to ensure the continuity and sealing of the water delivery process. The overall structural design is compact and reasonable, and the various components have clear division of labor and coordinated cooperation, which not only realizes efficient pumping from the drainage ditch 11 to the water storage chamber 12 and meets the water storage needs, but also facilitates installation, repair and maintenance, greatly improving the stability and reliability of the slope 1 drainage and greening ecological protection device.

[0049] As a preferred embodiment, the second pumping structure includes a third guide tube, a second pump body 18 and a fourth guide tube 19 which are connected in sequence, wherein one end of the third guide tube away from the second pump body 18 is connected to the water storage chamber 12, and one end of the fourth guide tube 19 away from the second pump body 18 is connected to the irrigation chamber 8.

[0050] In the above embodiment, the third guide pipe draws water from the water storage chamber 12, and can stably introduce the stored water resources into the pumping process, providing a reliable water source guarantee for subsequent transportation. The second pump body 18, as a power center, can flexibly adjust the pumping pressure and flow according to the actual irrigation needs, accurately control the amount of water delivered to the irrigation chamber 8, and meet the water needs at different time periods and under different vegetation growth conditions. The fourth guide pipe 19 smoothly guides the water pumped out by the second pump body 18 into the irrigation chamber 8, achieving seamless connection from water storage to irrigation. This structural design is compact and efficient, and the various components work closely together, which not only ensures efficient water delivery from the water storage chamber 12 to the irrigation chamber 8, and provides a stable water source for the irrigation of the vegetation on the slope 1, but also has the characteristics of easy installation and convenient maintenance, which greatly improves the irrigation efficiency and stability of the entire slope 1 drainage and greening system.

[0051] As a preferred embodiment, a nutrient solution adding port connected to the water storage chamber 12 is provided on the outer side of the slope 1, and a sealing plug 14 is detachably provided on the nutrient solution adding port;

[0052] Wherein, a stirring structure 13 is disposed in the water storage chamber 12 .

[0053] In the above embodiment, the nutrient solution addition port provides a convenient way to supplement the nutrients required for plant growth to the water storage chamber 12. Maintenance personnel can add nutrient solution in a timely manner according to the plant growth stage and needs, and accurately control the vegetation growth environment. The removable sealing plug 14 can not only ensure the sealing of the addition port during the non-addition period, prevent water evaporation and the entry of debris, maintain the cleanliness of the water body in the water storage chamber 12, but also facilitate opening for addition operations. After adding the nutrient solution, the stirring structure 13 can fully stir and mix the water body and the nutrient solution in the water storage chamber 12 to ensure that the nutrient solution is evenly distributed. This ensures that every drop of water irrigated to the slope contains an appropriate amount of nutrients, provides balanced nutritional support for plant growth, effectively promotes the healthy growth of vegetation, improves the greening effect of the slope 1, and enhances the stability and sustainability of the entire slope 1 ecological protection system.
