Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to an ecological water conservancy slope protection device. Background Art

[0002] Ecological water conservancy slope protection is a comprehensive project to support and protect the matrix or slope. It combines multidisciplinary knowledge such as engineering mechanics, soil science, ecology and botany. Its basic principle is to use its response with the soil to form a stable matrix. After excavating the slope, by planting appropriate vegetation on the slope, the plant root system can form a mesh structure with the soil complex, and use the growth of plants and the mechanical grip of the root system to stabilize the slope. At the same time, vegetation coverage can also effectively prevent soil landslides due to hydraulic or drought width. Compared with traditional concrete or pollutant concrete slope protection, ecological slope protection can not only meet the needs of protecting crops, but also can well restore the ecological environment after the natural slope is dug.

[0003] For example, a Chinese utility model patent with application number 2022220874588 discloses an ecological water conservancy engineering slope protection, including a slope protection body, the slope protection body includes a base layer, a first functional layer, a second functional layer and a nutrient soil layer, the first functional layer includes a reinforced concrete layer and an expanded perlite gravel layer, the second functional layer includes an anti-cracking mortar layer and a stable soil layer, and a fixing box is fixedly installed around the front side of the slope protection body, and the first functional layer is arranged on the outer surface of the base layer. The device is provided with a first functional layer including a reinforced concrete layer and an expanded perlite gravel layer and a second functional layer including an anti-cracking mortar layer and a stable soil layer, wherein the anti-cracking mortar layer not only improves the overall anti-cracking performance, but also has the advantages of high tensile strength, easy construction and anti-freezing, and the expanded perlite gravel layer has the characteristics of heat preservation, heat insulation, non-flammability, non-toxicity and good chemical stability, and the above structure can effectively improve the overall strength.

[0004] However, the above-mentioned slope protection device still has some problems in dealing with the pollution caused by rainwater erosion. First, the slope protection in ecological water conservancy projects is often located on both sides of the river and inclined toward the river. This location design has promoted the utilization of water resources and the improvement of the ecological environment to a certain extent, but it also brings certain environmental risks. Especially during rainfall, rainwater flows into the river along the inclined surface of the slope protection, often carrying various debris, such as fallen leaves, waste, etc., which leads to river pollution. Secondly, although the slope protection structure performs well in terms of erosion resistance and strength, the effect of preventing debris from entering the river is not satisfactory. For example, even if a fixed box is fixed on the front side of the slope protection, it is still difficult to completely intercept all debris, especially under heavy rain erosion. It is easier for debris to pass over these fixed structures and directly enter the river, causing river pollution. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: As shown in the figure, an ecological water conservancy slope protection device includes a slope protection body 2, the slope protection body 2 has a main planting area 3 distributed in an inclined surface, the front end of the slope protection body 2 is extended toward the river channel and is provided with a reinforced base 4, an interception frame 1 is provided on the reinforced base 4, the interception frame 1 has an upwardly open receiving groove, and the side wall of the interception frame 1 is provided with a through hole 8 connected to the receiving groove, a plurality of ecological frames 9 are stacked on both sides of the interception frame 1, and two oppositely distributed secondary planting areas 6 are provided on the main planting area 3, each secondary planting area 6 has a diversion bevel 5, and a diversion area for guiding debris to the receiving groove is formed between the two diversion bevels 5.

[0024] Embodiment 2: As shown in the figure, different from Embodiment 1, the slope protection body 2 includes a base layer 10, a reinforced concrete layer 11, an anti-cracking mortar layer 12 and a covering soil layer 13 which are stacked in sequence from the inside to the outside.

[0025] In the above structure, the base layer 10 usually uses a material with a thin thickness but high strength, such as crushed stone, crushed stone concrete or compacted soil, to provide good support and bearing capacity. The reinforced concrete layer 11 is the main part of the structure, which is cast by mixing materials such as cement, sand, aggregate and steel bars. It has high compressive strength and durability and can effectively withstand external loads and pressures. The anti-crack mortar layer 12 is generally composed of a mixture of cement, sand, special additives, etc., with certain flexibility and adhesion, which can effectively prevent the expansion of cracks and improve the impermeability and durability of the overall structure. The outermost covering layer 13 usually uses soil with good permeability and strong water retention or special covering materials to protect the slope protection structure from erosion and damage from the external environment, while providing a good soil environment for the growth of vegetation.

[0026] In this embodiment, the thickness ratios of the base layer 10, the reinforced concrete layer 11, the anti-cracking mortar layer 12 and the covering soil layer 13 are 1:2:1:2 respectively.

[0027] The base layer 10, reinforced concrete layer 11, anti-crack mortar layer 12 and covering soil layer 13 of the slope protection structure are designed according to the thickness ratio of 1:2:1:2. This proportion distribution takes into account the function and performance of each layer, so that the slope protection can play the best effect. First, the thinner design of the base layer 10 can effectively provide sufficient support, while reducing the amount of materials used and reducing the project cost. Secondly, the reinforced concrete layer 11, as the main structural layer, has a large thickness and can withstand large pressure and load, ensuring the overall stability and safety of the slope protection. The appropriate thickness of the anti-crack mortar layer 12 helps to slow down the expansion speed of cracks, increase the service life of the slope protection, and reduce maintenance costs. The outermost covering soil layer 13 has a large thickness, which can effectively protect the slope protection from erosion and damage from the external environment. It is also conducive to the growth of vegetation and beautifies the appearance of the slope protection. In general, this thickness ratio design can take into account the stability, durability and aesthetics of the slope protection, and achieve good engineering effects.

[0028] Embodiment 3: As shown in the figure, different from Embodiment 2, the main planting area 3 is located outside the covering soil layer 13 , and a plurality of planting frames 15 are distributed in the main planting area 3 , and the planting frames 15 are connected to the reinforced concrete layer 11 through anchor rods 14 .

[0029] In the above structure, the setting of the main planting area 3 can form a green vegetation cover layer on the slope protection structure, which not only beautifies the appearance of the slope protection, but also enables the vegetation to grow in an orderly manner, reduces competition between vegetation, and is convenient for management and maintenance. The connection between the anchor rod 14 and the reinforced concrete layer 11 enhances the stability of the planting frame 15, enabling it to withstand the weight of soil and plants and prevent falling off and deformation due to soil loss or plant growth.

[0030] In this embodiment, the anchor rod 14 is preset in the reinforced concrete layer 11 , and the planting frame 15 is provided with a reserved hole 16 adapted to the anchor rod 14 . The anchor rod 14 passes through the reserved hole 16 and is connected to the locking nut 17 .

[0031] In the above structure, the anchor rod 14 is preset in the concrete layer, which enhances the stability and tensile strength of the entire structure, can effectively resist external pressure and water flow impact, and prevent the slope protection structure from falling off and deformation. The planting frame 15 is provided with a reserved hole 16, so that the anchor rod 14 can easily pass through and is connected with the locking nut 17, forming a stable fixing system, ensuring the planting frame 15 is firmly connected to the slope protection structure, and is not easily affected by external factors and falls off or shifts. The connection method between the anchor rod 14 and the locking nut 17 is simple and reliable, easy to install and maintain, and improves the construction efficiency of the slope protection structure. In summary, this structural design not only ensures the stability and safety of the slope protection, but also improves its impact resistance and deformation resistance, ensuring that the slope protection structure can function stably and long-term.

[0032] In this embodiment, a water storage tank 18 is disposed on the top of the slope protection body 2 . The water storage tank 18 has a water diversion pipe 19 connected to an external water source, and a valve 20 is fixed on the side wall of the water storage tank 18 .

[0033] As a facility for accommodating external water sources, the water tank 18 can store and reserve water resources when needed and provide them to the vegetation or other ecosystems around the slope protection. A valve 20 is fixed on the side wall of the water tank 18. After opening the valve 20, the water source irrigates the plants in the main planting area 3 and the secondary planting area 6 through the irrigation equipment, providing the plants with necessary moisture and promoting their growth. This structural design effectively utilizes external water resources and realizes efficient management of plant irrigation, which not only improves the efficiency and quality of plant growth, but also reduces the labor cost of manual irrigation. In addition, the water flow in and out is controlled by the valve 20, and the irrigation water volume and frequency can be adjusted as needed to achieve the purpose of rationally utilizing water resources and saving water.

[0034] Embodiment 4: As shown in the figure, the difference from Embodiment 3 is that a heightening partition plate 7 is detachably provided at the upper end of the interception frame 1 , and a through groove 22 is provided on the side wall of the heightening partition plate 7 .

[0035] In the above structure, the detachable setting of the heightened partition 7 allows the height of the interception frame 1 to be adjusted as needed to adapt to different water flow conditions or environmental requirements. For example, when the rainfall is heavy or the water flow is turbulent, the height of the partition can be increased to improve the protection effect of the interception frame 1 and prevent the water flow from overflowing, thereby protecting the slope protection and the surrounding environment. The side wall of the heightened partition 7 is provided with a through groove 22, which can effectively guide the water flow, improve the fluidity and stability of the water flow, reduce the impact and fluctuation of the water flow, facilitate the smooth interaction between the water flow and the interception frame 1, and improve the capture efficiency of the interception frame 1.

[0036] The detachable setting of the heightened partition 7 and the interception frame 1 is a prior art. For example, corresponding grooves and protrusions can be designed on the upper edge of the interception frame 1 and the lower edge of the heightened partition 7 so that they can be easily inserted and fixed. In this way, when it is necessary to increase the height of the interception frame 1, it is only necessary to insert the protrusion of the heightened partition 7 into the groove of the interception frame 1, and then use screws or buttons and other fixing devices to tightly connect them together. When the heightened partition 7 is not needed, it is only necessary to easily unscrew or remove the heightened partition 7 to restore the interception frame 1 to its original state. This simple design not only facilitates disassembly and installation by operators and maintenance personnel, but also ensures the firmness and stability of the connection, thereby ensuring the effective function of the interception frame 1.

[0037] In this embodiment, ecological grass seeds 21 are mixed in the covering soil layer 13 .

[0038] In the above structure, the addition of ecological grass seeds 21 makes the covering layer 13 no longer just a simple covering, but an active ecosystem. After the grass seeds germinate and grow in the covering layer 13, they can form a dense grass cover layer, which can effectively prevent soil erosion, slow down the flow of water, reduce surface runoff and soil loss, thereby protecting the slope protection structure and reducing pollution to the river. The roots of the grass seeds can firmly fix soil particles, enhance the stability and impact resistance of the covering layer 13, prevent weathering and erosion of the covering layer 13, and extend the service life of the slope protection.

[0039] The selection of ecological grass seeds 21 is based on local actual conditions. For example, perennial grass seeds such as grass and bahia grass can be selected. These grass seeds have good adaptability and drought resistance, can grow under different environmental conditions, form dense grassland coverage, and effectively prevent soil erosion and soil erosion. You can also choose herbaceous plants suitable for ecological slope protection, such as alfalfa and yellow clover. These herbaceous plants have strong root systems and stress resistance, can grow rapidly in the covering layer 13, stabilize the soil, and enhance the stability of the slope protection.

[0040] In this embodiment, the ecological frame 9 is a fish nest type ecological frame 9.

[0041] The fish nest type ecological frame 9 is an existing product, and its structure has multi-layer space, which can provide rich habitats and protective environment, and provide a safe place for various aquatic organisms to live and reproduce. In addition, the porous structure of the fish nest type ecological frame 9 allows water to flow smoothly, providing a suitable water flow environment for aquatic organisms, which is conducive to the swimming, hunting and spawning of fish.

[0042] In this embodiment, a road belt 23 for people to walk is also provided in the main planting area 3.

[0043] The setting of the road belt 23 is convenient for people to walk, which helps to protect the vegetation in the main planting area 3, avoid human trampling and damage, ensure a good environment for plant growth, and maintain the stability of the ecosystem.

[0044] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
