Description

[0001] The utility model belongs to the technical field of water and soil conservation, specifically relates to an ecological slope protection water and soil conservation device. BACKGROUND

[0002] As a multi-disciplinary cross slope protection technology system, the core mechanism of ecological slope protection is to build a biological-mechanical coupling system of plant root system and rock-soil medium. Through the three-dimensional root network of herbaceous and shrub vegetation, the surface soil is reinforced and anchored, and the stress of deep rock mass is dispersed, forming an ecological protection layer with self-repairing ability. Compared with traditional hard slope protection engineering, this technology can rebuild biological habitat environment, regulate microclimate and purify surface runoff while maintaining the stability of the slope structure by simulating natural ecological system. However, the current practice focuses on surface vegetation coverage, lacks systematic intervention in the water and soil interaction process, resulting in surface soil erosion gullies in heavy rainfall events, causing vegetation degradation and even slope instability, exposing the protective limitations of single ecological measures.

[0003] In the utility model with the authorization announcement number CN222715908U, an ecological slope for water and soil conservation is disclosed. The hollow brick frame structure of the slope structure can improve the planting conditions through multi-layer tamping soil and nutrient medium, but it still belongs to passive protection in essence. The scheme has the following bottlenecks: the scheme still belongs to the shallow fixed mode in essence, and the reinforcement effect mainly depends on the physical improvement of the planting soil layer. It fails to establish a collaborative protection mechanism of deep root network and engineering structure, and there is a risk of soil consolidation efficiency decay when dealing with long-term water and soil loss or extreme climate, which makes it difficult to realize the sustainable water and soil conservation function of ecological slope system. Secondly, the shallow tamping soil cannot form effective interlocking with the underlying bedrock, and is prone to interlayer slip under long-term dry-wet cycle.

[0037] As shown in the description accompanying drawings Figures 1-5 The utility model provides a technical scheme:

[0038] The ecological slope protection water and soil conservation device is used for being installed on the surface of the ecological slope 1 and plays a role of ecological slope protection water and soil conservation. The ecological slope protection water and soil conservation device comprises a grid block 2 and a separation positioning assembly arranged on the lower side of the grid block 2. The ecological slope 1 is divided into a plurality of independent water and soil conservation units through the cooperation of the grid block 2 and the separation positioning assembly. Specifically, the grid block 2 is a prefabricated reinforced concrete, and adjacent grid blocks 2 are connected through a mortise and tenon structure to form an integral protection layer on the surface layer of the ecological slope 1. A plant protection area 4 is formed in the central grid groove 25 of the grid block 2, and the biological protection function of the surface soil is realized by planting vegetation in the soil layer of the plant protection area 4. The separation positioning assembly is arranged in the lower soil layer of the grid block 2 and vertically penetrates the slope floating soil layer and extends to the bearing layer to form a rigid connection system with the grid block 2. The assembly divides the lower soil body into independent units through deep embedding fixation and forms a three-dimensional water and soil conservation frame with the upper grid block 2, thereby enhancing the overall stability of the slope and preventing the spread of local water and soil loss through unitized isolation design, and finally constructing a composite slope system with engineering protection and ecological restoration functions.

[0039] In a preferred embodiment, as shown in Figure 1 and Figure 2 , the grid block 2 is a special-shaped concrete prefabricated structure, and the lower side of the body is provided with symmetric positioning cones 21 at the four corners. The positioning cone 21 is in the form of an inverted triangular cone. During installation, the four positioning cones 21 are vertically pressed into the surface soil of the ecological slope 1 to form a mechanical engagement fixation structure, effectively limiting the translation and rotation of the grid block 2 in the slope direction, and ensuring the rigid connection of the protection layer and the slope soil. At the same time, the inverted triangular structure of the positioning cone 21 has excellent anti-pulling performance. The wedge-shaped constraint effect is formed between the side of the cone and the contact surface of the soil, and the overall structural stability can be significantly enhanced by the weight of the grid block 2. The positioning assembly penetrates the floating soil layer and reaches the bearing layer through the embedding mode, and together with the separation positioning assembly, it forms a three-dimensional anchoring system, which not only ensures the accurate positioning of the grid block 2, but also realizes the physical isolation function of the water and soil conservation unit.

[0040] In a preferred embodiment, as shown in Figure 1 and Figure 2 , the grid block 2 is a special-shaped concrete prefabricated structure, and the lower side of the body is provided with symmetric positioning cones 21 at the four corners. The positioning cone 21 is in the form of an inverted triangular cone. During installation, the four positioning cones 21 are vertically pressed into the surface soil of the ecological slope 1 to form a mechanical engagement fixation structure, effectively limiting the translation and rotation of the grid block 2 in the slope direction, and ensuring the rigid connection of the protection layer and the slope soil. At the same time, the inverted triangular structure of the positioning cone 21 has excellent anti-pulling performance. The wedge-shaped constraint effect is formed between the side of the cone and the contact surface of the soil, and the overall structural stability can be significantly enhanced by the weight of the grid block 2. The positioning assembly penetrates the floating soil layer and reaches the bearing layer through the embedding mode, and together with the separation positioning assembly, it forms a three-dimensional anchoring system, which not only ensures the accurate positioning of the grid block 2, but also realizes the physical isolation function of the water and soil conservation unit.

[0041] Specifically, as shown in Figure 2 and Figure 3As shown, the locking groove 22 and the locking protrusion 23 are both provided with coaxial through positioning holes 24, which are vertically connected with the positioning anchor rods 3 of the partition positioning assembly. Therefore, when the positioning cone 21 is embedded in the soil, the positioning anchor rods 3 are inserted into the positioning holes 24 to achieve the rigid connection between the grid block 2 and the partition positioning assembly, and finally build a three-dimensional water and soil conservation structure composed of the surface protection unit, the middle layer mortise and tenon frame and the deep anchoring system, which significantly improves the overall anti-erosion performance of the slope protection system.

[0042] In a preferred embodiment, as shown in Figure 2 、 Figure 3 and Figure 4 , the partition positioning assembly includes the positioning anchor rods 3 and the partition net plate 5. The positioning anchor rods 3 are detachably connected with the grid block 2, and the anchor rod bodies of the positioning anchor rods 3 vertically penetrate the partition net plate 5 and extend to the slope bearing layer. Through the frictional resistance of the rod body and the soil and the end expansion structure, a double anchoring mechanism is formed, which not only achieves the rigid connection between the grid block 2 and the deep soil, but also serves as the main force-bearing member to bear the water and soil pressure on the slope surface, effectively improving the overall stability of the protection structure. The partition net plate 5 is made of degradable environmentally friendly materials in a grid net structure and is pre-buried in the slope soil layer in a vertical posture during installation. The net plate cooperates with the positioning anchor rods 3 to divide the soil into independent water and soil conservation units through grid segmentation, and its porous structure can promote the penetration and growth of plant roots. With the passage of time, the degradable net plate gradually decomposes into organic matter, which not only maintains the initial soil partition function, but also provides a nutrient circulation carrier for the ecological restoration of the later plant protection area 4, forming a gradual transition of engineering protection and ecological restoration.

[0043] Specifically, as shown in Figure 2 、 Figure 3 and Figure 4As shown, the partition net plate 5 adopts radial blocking plate and weft blocking plate orthogonal connection to form a grid structure, and a plurality of diamond-shaped flow guiding and positioning holes 51 are formed in the net plate plane. The pore system is designed by geometric optimization, so that the flow guiding channel cross section of the single flow guiding and positioning hole 51 is in a streamlined structure with a wide inlet and a narrow outlet. The pore system can form a water guiding path in the horizontal soil layer during rainfall, guide the excess water to quickly infiltrate to the slope foot position, and can also generate turbulent disturbance effect on the runoff through the blocking plate structure of the pore edge, effectively weakening the scouring kinetic energy of the water flow on the slope soil. The diamond-shaped opening size of the flow guiding and positioning hole 51 is matched with the growth characteristics of the plant root system, and the pore diameter is designed to change in the depth direction of the soil layer. In the early stage of vegetation restoration, the pores provide horizontal expansion space for the root system of the herbaceous plant, and as the plant grows, the root system can penetrate the degradable net plate material to form a three-dimensional anchoring network. When the net plate material is gradually degraded, the original grid space is converted into a permanent root channel, realizing the natural transition of the engineering protection structure to the biological protection system, and finally constructing a composite slope protection system with water and soil conservation and ecological restoration functions.

[0044] Specifically, as shown in Figure 2 、 Figure 3 and Figure 4 , a through hole 52 is arranged at the orthogonal connection of the radial blocking plate and the weft blocking plate of the partition net plate 5, which is matched with the positioning anchor rod 3 for use, so that the positioning anchor rod 3 can pass through in use, thereby enhancing the compression strength of the partition net plate 5 in use.

[0045] In a preferred embodiment, as shown in Figure 1 、 Figure 3 and Figure 5 , the positioning anchor rod 3 is made of a variable-strength resin composite material, and a continuous spiral external thread structure is arranged on the outer wall of the rod body. The thread design enhances the frictional resistance between the anchor rod and the soil through mechanical engagement, and cooperates with the high-low strength gradient distribution characteristics of the rod body to form a rigid-flexible stress system at the anchoring section: the high-strength head ensures the initial anchoring force, and the low-strength tail can adapt to the soil displacement through controllable deformation, thereby effectively improving the adaptability of the anchor rod in complex geological conditions. The positioning anchor rod 3 has an environment-responsive degradation characteristic, and the main material is added with a biodegradable additive to realize performance attenuation control within a preset service period. After the plant root network in the slope protection vegetation area 4 is developed and matured, the anchor rod is gradually degraded into harmless organic matter, which avoids long-term interference of permanent engineering materials on the ecological system, and provides continuous nutrient supply for the plant protection area 4 through the material decomposition process, thereby forming a gradual functional transition mechanism from engineering reinforcement to ecological self-sustaining.

[0046] The construction process of the ecological slope protection water and soil conservation device includes:

[0047] Step 1: slope surface pretreatment and partition net plate installation;

[0048] Clean the surface soil and loose layer of the ecological slope protection 1, and drill vertical holes to the bearing layer at the designed intervals; vertically insert the separator mesh 5 made of biodegradable material into the soil layer to ensure that the mesh plane is aligned with the water quality of the slope, and the diversion holes 51 are distributed in rows and columns; through the cross structure of radial and latitudinal baffles, the slope protection soil is divided into independent soil and water conservation units, and at the same time, the initial diversion channel is constructed using diamond-shaped pores;

[0049] Step 2: Insertion and anchoring of positioning anchor bolt 3;

[0050] The high and low strength resin positioning anchor rods 3 are passed through the reserved holes of the partition mesh plate 5 and screwed into the drill hole to the design depth through the external thread structure; the high strength section of the anchor rod head is aligned with the positioning hole 24 of the grid block 2, and the low strength section of the tail is reserved for degradation space; the anchoring agent is injected to fill the gap between the anchor rod and the hole wall, forming a double fixation of mechanical interlocking and chemical bonding, ensuring the rigid connection between the anchor rod 3 and the slope protection 1;

[0051] Step 3: Grid block splicing and protective layer construction

[0052] Precast grid blocks 2 are laid layer by layer from the toe of the slope upwards, and horizontal and vertical splicing is achieved through the tenon and mortise structure of locking grooves 22 and locking protrusions 23; the four positioning cones 21 of each grid block 2 are inserted into the node area of ​​the partition mesh plate 5 to form a grid-like protective frame; planting soil is laid in the grid groove 25, and hydraulic connection is established with the deep soil through the diversion clearance hole 51, while providing substrate space for subsequent planting.

[0053] Step 4: Structural Connection and Ecological Initialization;

[0054] By injecting high-strength grout into the positioning hole 24, the anchor rod 3, the partition mesh plate 5 and the grid block 2 form an integrated force-bearing system; and by sowing herbaceous or shrub seeds in the plant protection area 4, the initial rainwater is guided to infiltrate through the diversion hole 51 to avoid surface runoff erosion.

[0055] The working principle of the ecological slope protection and soil and water conservation device described in this utility model includes:

[0056] Soil and water conservation stage: During rainfall, slope runoff seeps vertically downward through the diversion holes 51 of the dividing mesh plate 5. The rhomboid pore structure generates turbulence and energy dissipation effect on the water flow, weakening the scouring force. Independent soil and water conservation units limit the migration range of soil particles, and together with the frame shear structure of the grid block 2, prevent the surface soil from sliding. The positioning anchor rod 3 resists the structural deformation caused by soil and water pressure through the frictional resistance between the external thread and the soil and the deformation adaptability of the rod body. Its degradable characteristics avoid long-term engineering interference.

[0057] Ecological transition and self-maintenance stage: the plant roots grow downward along the drainage positioning hole 51, and grow transversely to penetrate the degradable partition net plate 5 to form a three-dimensional anchoring network. As the net plate material gradually decomposes, the original pore is converted into a permanent root channel, enhancing the shear strength of the soil body; the positioning anchor rod 3 is degraded into organic matter within a predetermined period of time, providing nutrients for plants through the pore system, while the reinforced concrete structure of the grid block 2 continues to play a protective role, realizing the gradual transition from engineering measures to biological measures. The independent soil and water conservation unit inhibits the expansion of local erosion, and the mortise and tenon connection structure allows a small amount of deformation without losing integrity, prolonging the service life of the slope protection system.

[0058] The above merely describes a preferred embodiment of the present application, and is not intended to limit the scope of protection of the present application.
