Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to a stable and assembled water conservancy ecological slope protection and drainage structure. Background Technology

[0002] Hydraulic ecological slope protection is a new type of slope protection technology that integrates engineering protection and ecological restoration functions. It aims to restore and optimize the aquatic ecological environment while ensuring the safety and stability of water conservancy facilities such as rivers and dams, and to achieve harmonious coexistence between humans and water. Hydraulic ecological slope protection is a slope protection technology that integrates the basic knowledge of engineering mechanics, soil science, ecology and botany to support slopes or sides, forming a comprehensive slope protection system composed of plants or engineering and plants.

[0003] After the excavation of the slope, ecological slope protection involves planting vegetation to protect and reinforce the surface layer of the slope through the interaction between the plants and the rock and soil (root anchoring effect). This method not only meets the requirements for the stability of the slope surface but also restores the damaged natural ecological environment, making it an effective means of slope protection and stabilization.

[0004] Existing water conservancy ecological slope protection and drainage structures typically use a combination of plants and geotextiles or permeable concrete. Geotextiles are prone to aging and breakage, which affects their later erosion resistance. Permeable concrete is laid by interlocking, and water erosion may cause the concrete to peel off, making it prone to landslides and loosening, thus affecting the quality and safety of the slope protection.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Among the currently discovered feasible technologies, the following are described:

[0024] As an important technology integrating modern water conservancy engineering and ecological restoration, water conservancy ecological slope protection breaks through the limitations of traditional hard slope protection that "emphasizes safety but neglects ecology". Through material innovation, structural optimization and ecological function reshaping, water conservancy ecological slope protection is a comprehensive slope protection technology that achieves multiple goals such as flood control and bank stabilization, ecological restoration, water purification and landscape creation. It is based on slope stability and realizes the coordinated development of flood control and bank stabilization and ecological protection.

[0025] Hydraulic ecological slope protection is a comprehensive slope protection technology that, based on maintaining slope stability, also integrates multiple functions such as ecological restoration, water purification, and habitat creation. Its core objective is:

[0026] Engineering safety: To resist water erosion, wind and wave erosion and landslides, and to ensure the safety of water conservancy facilities such as river channels and dikes;

[0027] Ecological restoration: Restoring damaged aquatic ecosystems and enhancing biodiversity;

[0028] Environmental benefits: purifies water, regulates microclimate, and reduces soil erosion;

[0029] Social benefits: Creating a waterfront landscape promotes harmony between people and water, and provides recreational and educational spaces for the public.

[0030] Ecological slope protection achieves its functional goals through the synergistic effect of "materials-structure-biology":

[0031] In terms of materials: environmentally friendly materials such as permeable concrete, eco-bags, and geogrids are used, which combine mechanical strength and eco-friendliness;

[0032] Structural level: Design biomimetic structures (such as artificial reefs and stepped structures) to disperse water flow energy and reduce slope erosion;

[0033] At the biological level: plant roots are used to stabilize the soil and microorganisms decompose pollutants to build a self-sustaining ecosystem.

[0034] Plant-based ecological slope protection includes pure vegetation slope protection: suitable for areas with gentle slopes and low water flow rates, it uses herbaceous plants (such as bermudagrass) and shrubs (such as Amorpha fruticosa) to stabilize the soil and protect the slope. It is low in cost but has weak initial protection capabilities and needs to be combined with soil improvement measures; plant-material composite slope protection: combined with auxiliary materials such as three-dimensional geonets and coconut fiber blankets, it enhances the slope's resistance to erosion and is often used in the initial stage of slope restoration.

[0035] Porous materials for slope protection include permeable concrete slope protection: with a porosity of 15%-30%, it allows water infiltration and plant growth, but has lower strength and is suitable for landscape waterways; and ecological brick slope protection: precast concrete bricks with planting troughs that can be embedded with herbaceous plants, combining aesthetics and ecological functions.

[0036] Flexible slope protection structures include: eco-bag slope protection: soil and grass seeds are filled into biodegradable bags and stacked to form a stepped structure, which can adapt to foundation settlement and is often used on steep slopes or drawdown zones; geogrid slope protection: stability is enhanced by the friction between the geogrid and the soil, and can be combined with hydroseeding, which is suitable for high fill slopes.

[0037] The design principles for slope protection include: adapting to local conditions: selecting appropriate technologies based on slope gradient, geological conditions, and water flow velocity; prioritizing ecology: giving priority to the use of native plants to reduce the risk of invasion by alien species; and functional synergy: taking into account multiple needs such as flood control, ecology, and landscape, and avoiding the overemphasis on a single function.

[0038] Slope protection design parameters include slope and slope height: gentle slopes (<1:1.5) are suitable for vegetation slope protection, while steep slopes (1:1) require engineering measures; material selection: the compressive strength of permeable concrete should be ≥C20, and the UV resistance of ecological bags should meet the requirements of more than 5 years of service; plant configuration: flood-tolerant plants (such as reeds) should be planted below the normal water level, and drought-tolerant varieties (such as bermudagrass) should be planted above the flood level.

[0039] Please refer to Figures 1-5, A stable assembled water conservancy ecological slope protection drainage structure, including an installation base 1 and a limiting frame 7. The installation base 1 is made of waterproof concrete to resist scouring and corrosion. A steel bar framework is installed inside the installation base 1. The installation base 1 is formed by pouring to support and limit. The limiting frame 7 is clamped at the top of the installation base 1. A number of drain holes 2 are provided on the side wall of the installation base 1. Anchor rods 3 are inserted at the bottom end of the installation base 1. The anchor rods 3 are used to anchor the installation base 1 to improve the stability of the connection between the installation base 1 and the slope. A through groove 10 is provided at the bottom end of the installation base 1. A support plate 12 is fixed on the inner side wall of the through groove 10. The installation base 1 and the support plate 12 are fixedly connected to form an integral structure. A first socket 15 is provided in the middle of the support plate 12 for the anchor rod 3 to be inserted, improving the convenience of inserting and positioning the anchor rod 3. The inner side wall of the installation base 1 is clamped with a sandbag 5. A filling layer 11 is filled in the middle of the installation base 1. The filling layer 11 is large-particle gravel. The intermediate gaps in the filling layer 11 are for drainage and filtration. Connecting rods 4 are inserted on the side walls of the installation base 1. Two second sockets 16 are provided on the side walls of the installation base 1. The second sockets 16 are symmetrically distributed for the connecting rods 4 to be inserted, improving the stability of inserting the connecting rods 4, so that the installation bases 1 are horizontally connected into one body. Two positioning columns 8 are fixedly provided on the side walls of the installation base 1. Two positioning grooves 9 are provided on the side walls of the installation base 1 away from the positioning columns 8. The positioning columns 8 are symmetrically distributed. The positioning grooves 9 penetrate through the side walls of the installation base 1. The positioning columns 8 are sequentially inserted into the middle of the positioning grooves 9, improving the convenience of installing and positioning the positioning columns 8 and the positioning grooves 9, thus improving the stability of the lateral connection of the installation base 1. A substrate layer 6 is filled at the top of the installation base 1 close to the filling layer 11. The substrate layer 6 is used for the growth of the root systems of herbaceous plants. The limiting frame 7 is used to support and limit the substrate layer 6 to improve the stability of planting, thus improving the overall stability of the slope protection installation, reducing the risk of scouring and landslide damage by water flow, and improving the quality and safety of the slope protection.

[0040] The drain holes 2 are symmetrically distributed. The drain holes 2 are sequentially connected to the inside of the installation base 1. The sandbag 5 is in a square shape with a loop. Gravel 18 is filled in the middle of the sandbag 5. The filling layer 11 is clamped in the middle of the sandbag 5 to improve the stability of drainage.

[0041] A limiting frame 17 is fixed at the top of the installation base 1. The limiting frame 17 is in a square shape with a loop for the limiting frame 7 to be clamped. A number of clamping grooves 13 are provided on the surface of the limiting frame 7. Clamping strips 14 are fixed at both ends of the limiting frame 7. The clamping strips 14 are sequentially clamped at the bottom end of the limiting frame 17, improving the stability of installing the limiting frame 7.

[0042] When using this water conservancy ecological slope protection drainage structure, the construction workers first place the mounting bases 1 in designated positions, and then insert the positioning columns 8 into the positioning slots 9 in sequence, thereby improving the convenience and stability of the horizontal stacking of the mounting bases 1. Next, the anchor rods 3 are inserted into the first slot 15 in sequence, so that the anchor rods 3 are inserted into the soil of the slope. A slope refers to a geological body with an inclined surface. Slopes are usually caused by natural geological processes or human engineering activities. Then, the limiting frames 17 are aligned in sequence. Slopes are usually located on both sides of a river or the edge of a mountain. The anchor rods 3 are anchored to the mounting bases 1 by friction with the slope, thereby preventing the mounting bases 1 from sliding and loosening. Finally, sand is added... Bag 5 and filling layer 11 are sequentially snapped into the middle of the second slot 16 for filtering and drainage. Then, connecting rod 4 is sequentially inserted into the middle of the second slot 16, thereby improving the overall stability of the horizontal connection of the mounting base 1. Then, the matrix layer 6 is filled into the interior of the mounting base 1. Then, the limiting frame 7 is snapped into the middle of the limiting frame 17 to separate the matrix layer 6 for the growth of herbaceous plants, thereby improving the uniformity of plant growth distribution and the stability of plant root growth. At the same time, the limiting frame 7 improves the stability of the surface filling of the matrix layer 6, thereby improving the overall stability of the slope protection installation, reducing the risk of water erosion and landslide damage, and thus improving the quality and safety of the slope protection.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
