Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope protection technology, specifically to a prefabricated vegetation bag anchoring frame for lattice-type slope protection. Background Technology
[0002] With the rapid development of infrastructure construction such as highways and railways, a large number of artificially excavated high and steep slopes have been formed. If these slopes are not effectively protected, they are very susceptible to soil erosion, shallow peeling, and even geological disasters such as landslides and collapses under the influence of natural factors such as rainfall and weathering, which seriously threaten the safety of the project and the ecological environment.
[0003] Currently, slope protection technologies are mainly divided into two categories: traditional "hard protection" engineering measures and "soft protection" ecological measures.
[0004] While hard protective structures, such as cast-in-place concrete grid beams, shotcrete facing, and masonry retaining walls, can provide high initial stability, their drawbacks are becoming increasingly apparent. First, these structures are ecologically destructive, forming impermeable and airtight physical barriers that sever the exchange of matter and energy between the slope and the natural environment, resulting in the complete destruction of the original vegetation, poor landscape effects, and running counter to the concept of green development. Second, their construction process is complex, relying on on-site pouring, requiring a large amount of formwork and manpower, with long construction cycles, great susceptibility to weather conditions, and high project costs. Over time, problems such as concrete aging, cracking, and steel corrosion will weaken their long-term protective effect, and the structure itself does not have the ability to self-repair.
[0005] Soft protection, such as traditional hydroseeding and planting grass in holes, aims to prevent soil erosion by restoring vegetation. However, these technologies are usually only suitable for stable slopes with gentle slopes and fertile soil. For steep, barren, or easily eroded slopes, their application effect is often poor. Plant seeds are easily washed away by rainwater, and the lack of soil moisture and nutrients leads to low germination and survival rates. In addition, the plant root system is generally shallow, so the mechanical reinforcement it can provide to resist deep sliding is negligible. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a prefabricated vegetation bag anchor frame for lattice slope protection, which aims to achieve a long-term, stable and deep-integrated anchoring structure between the vegetation bag anchor frame and the slope.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A prefabricated vegetation bag anchoring frame for lattice-type slope protection includes:
[0009] A prefabricated anchor frame is laid on the slope surface. It has at least one set of receiving cavities for placing vegetation bags inside. The upper surface of the prefabricated anchor frame is also provided with a groove, which is located directly above the receiving cavity and the two are connected. The prefabricated anchor frame is also provided with anchor holes distributed through the thickness direction.
[0010] A composite pad is provided within the groove;
[0011] An anchor rod passes through the composite cushion layer and the anchor hole in sequence and extends into the interior of the slope. The anchor rod is equipped with an isolation device that divides the anchor rod along its length into a grouting anchor section and an ecological anchor section. The grouting anchor section is grouted to fix the anchor rod inside the slope. The ecological anchor section is located in the anchor hole and is filled with vegetation substrate between itself and the wall of the anchor hole.
[0012] Furthermore, the prefabricated anchoring frame is also provided with at least one root guiding channel, which connects the receiving cavity and the ecological anchoring section to guide the plant roots in the planting bag into the planting substrate in the ecological anchoring section to grow and entwine with the anchor rod.
[0013] Furthermore, the isolation device includes a retaining ring pre-installed on the outer wall of the anchor rod and a grout-stopping plug sleeved on the rod body. The retaining ring is located within the ecological anchoring section, and the grout-stopping plug is located below the retaining ring.
[0014] Furthermore, the root guiding channel includes a sidewall root guiding channel disposed on the sidewall of the receiving cavity and used to connect the receiving cavity and the anchoring hole.
[0015] Furthermore, the sidewall root system guiding channel includes a connecting channel connecting two adjacent anchor holes and a branch channel extending from the inner wall of the receiving cavity and the lower end face of the prefabricated anchor frame and communicating with the connecting channel.
[0016] Furthermore, the root guiding channel also includes a bottom plate root guiding channel disposed on the bottom plate of the receiving cavity. The bottom plate root guiding channel is a through hole running vertically through the slope to guide plant roots through and into the interior of the slope.
[0017] Furthermore, the composite pad layer includes a geogrid and a biodegradable fiber pad distributed from top to bottom, wherein the biodegradable fiber pad is a coconut fiber pad embedded with highly absorbent resin particles.
[0018] Furthermore, the lower end face of the biodegradable fiber pad is provided with a nutrient delivery layer, which is composed of polymer-coated slow-release fertilizer particles.
[0019] Furthermore, the bottom plate of the receiving cavity is provided with protrusions at intervals.
[0020] Furthermore, the prefabricated anchoring frame is provided with tenons and mortises on opposite sides for sliding and engaging.
[0021] Furthermore, the lower end of the prefabricated anchor frame is also fixedly connected with anchor spikes.
[0022] The technical solution provided by this utility model has the following advantages compared with the prior art:
[0023] 1. By setting up root guidance channels connecting the containment cavity and the ecological anchoring section, plant roots are guided to entwine with the anchor rods and penetrate deep into the slope through the root guidance channels of the bottom plate, forming a root network that connects the prefabricated anchoring frame, anchor rods and deep soil into one. The root network and the mechanical anchoring of the anchor rods work together to provide shear strength and overall stability that dynamically increase with vegetation growth compared to existing technologies.
[0024] 2. The composite cushion layer adopts a structure of geogrid + biodegradable fiber layer + nutrient delivery layer. The geogrid can serve as a fixing layer for the planting bags, which can distribute vertical loads and reduce lateral displacement of the elm soil. The biodegradable fiber layer can further reduce rainwater erosion. Moreover, the embedded SAP particles can quickly absorb and store dozens of times their own weight of water during rainfall or irrigation, and slowly release it during drought, providing a continuous water source for plant roots, thereby greatly improving the survival rate of plants in harsh slope environments. The nutrient delivery layer, composed of polymer-coated slow-release fertilizer particles, can continuously and stably provide essential nutrients such as nitrogen, phosphorus, and potassium to the root zone for several months or even a year, according to the plant's growth cycle.
[0025] 3. By setting a retaining ring on the anchor rod to limit the axial displacement of the grout plug, the anchor rod is divided into two parts: the ecological anchoring section and the grouting anchoring section, which prevents the grout from flowing back into the space where the vegetation substrate is located during grouting.
[0026] 4. The protrusions on the bottom plate of the receiving cavity not only increase the friction between the plant bag and the receiving cavity, preventing the plant bag from sliding in the receiving cavity and the substrate inside the bag from settling and moving, but also form tiny air gaps at the bottom of the plant bag, which greatly improves the drainage and ventilation conditions in the root zone and effectively prevents the problem of plant root rot caused by water accumulation.
[0027] 5. The lower end face of the prefabricated anchor frame is equipped with anchor spikes, which can penetrate into the surface of the slope during installation, playing a role in temporary positioning and initial fixation against sliding. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0041] like Figures 1-6 As shown, this utility model provides a prefabricated vegetation bag anchor frame for lattice slope protection, including a prefabricated anchor frame 1, a composite cushion layer 2, and an anchor rod 3.
[0042] Specifically, the prefabricated anchor frame 1 is a rectangular frame prefabricated from concrete or high-strength materials. It has one or more receiving cavities 102 inside to accommodate standard-sized planting bags 5. The planting bags 5 are pre-filled with substrate and plant seeds. A rectangular groove 101 is also provided on the upper surface of the prefabricated anchor frame 1 for placing the composite pad layer 2. The groove 101 is located directly above the receiving cavity 102 and the two are connected. Each of the four corners of the groove 101 is provided with a set of anchor holes 105 so that the anchor rod 3 can pass through.
[0043] To achieve a quick and stable connection between adjacent prefabricated anchor frames 1, tenon and mortise structures are provided on the two oppositely distributed outer side walls of the prefabricated anchor frames 1. More specifically, in this embodiment, the... Figure 1 As shown, the left and upper outer walls of the prefabricated anchor frame 1 are integrally formed with tenons 103, and the right and lower outer walls are provided with mortises 104 that correspond to the position of the tenons 103 and are engaged with them. Two adjacent sets of prefabricated anchor frames 1 can be engaged with each other through the tenons 103 and the mortises 104.
[0044] Root guidance channels 106 and 107 are respectively provided on the four side walls and the bottom plate of the receiving cavity 102. The side wall root guidance channels 106 are as follows: Figure 3 and Figure 5 As shown, it includes a connecting channel 1062 connecting two adjacent anchoring holes 105, and multiple sets of branch channels 1061 extending from the side wall of the receiving cavity 102 to the connecting channel 1062 and from the lower end face of the prefabricated anchoring frame 1 to the connecting channel 1062, while the base plate root system guide channel 107 is as follows. Figure 5 As shown, multiple sets of through holes are provided on the bottom plate of the receiving cavity 102, which makes the bottom plate of the receiving cavity 102 have a grid structure. Moreover, the root guide channel 107 of the bottom plate can also serve as a drainage channel to facilitate the drainage of water inside the receiving cavity 102.
[0045] In addition, multiple sets of protrusions 108 are integrally formed on the upper surface of the bottom plate of the receiving cavity 102. The protrusions 108 can increase the friction with the planting bag 5, reduce the sliding of the planting bag 5 inside the receiving cavity 102 and the sliding of the substrate inside the planting bag 5, and can also form a tiny air gap at the bottom of the planting bag 5, improve the drainage and ventilation conditions of the root zone, and prevent root rot caused by water accumulation.
[0046] Multiple sets of anchor spikes 109 are evenly arranged on the lower end face of the prefabricated anchor frame 1. During the installation process, the anchor spikes 109 can initially penetrate into the surface of the slope and play a temporary fixing role to prevent slippage before the anchor rod 3 is installed.
[0047] Composite pad 2 Figure 3 and Figure 5 As shown, geogrid 201 and biodegradable fiber mat 202 are stacked from top to bottom within the groove 101. The geogrid 201 is a bidirectional or multidirectional geogrid made of polymer materials such as polypropylene (PP) or high-density polyethylene (HDPE), with an ultimate tensile strength of not less than 40 kN / m. Its main function is to enhance the shear strength and deformation resistance of the planting bag, preventing the substrate inside the planting bag from being washed away by rainwater. It should be noted that if the planting bag 5 contains shrubs or trees with large root systems, holes that meet the requirements can be pre-drilled in the middle of the geogrid 201 or holes can be opened later. In this embodiment, the biodegradable fiber mat 202 is a coconut fiber mat. The coconut fiber mat is... The needle-punched mesh structure further reduces rainwater erosion. The geogrid 201 and the biodegradable fiber mat 202 work together to effectively resist the impact of raindrops and the erosive force of slope runoff, firmly fixing the substrate inside the planting bag 5. This provides a safe and stable environment for the germination of plant seeds and the growth of seedlings. Furthermore, highly absorbent polymer (SAP) particles are embedded inside the biodegradable mat 202. During rainfall or irrigation, the SAP particles can quickly absorb and store water, while during drought, they slowly release water to the plant roots, thereby improving the plant survival rate. Moreover, the coconut fiber mat is 100% biodegradable. After the coconut fiber mat degrades and disappears, the plants inside the planting bag can continue to grow through the geogrid 201.
[0048] In addition, a nutrient delivery layer 203 composed of polymer-coated slow-release fertilizer particles is attached to the lower end of the biodegradable fiber mat 202. The slow-release fertilizer particles can continuously and stably provide essential nutrients such as nitrogen, phosphorus, and potassium to the root zone for several months or even several years according to the plant's growth cycle, avoiding the instantaneous loss of nutrients. Moreover, when the SAP particles in the biodegradable fiber mat 202 release water, they can simultaneously release the slow-release fertilizer particles in the polymer coating, so as to simultaneously replenish water and fertilizer to the seeds in the planting bag.
[0049] To clearly illustrate the structure of the composite pad 2, the molding process of the composite pad 2 is described in this embodiment:
[0050] First, polymer-coated slow-release fertilizer granules are evenly spread on the bottom mold of the production line. The thickness depends on the designed fertilizer effect period (e.g., 6 months or 12 months). Then, treated fluffy coconut fiber is evenly spread on the slow-release fertilizer granule layer using a fiber laying device. During this process, superabsorbent polymer (SAP) granules and coconut fiber are mixed together and evenly distributed in the biodegradable fiber mat 202. Next, through light rolling, the slow-release fertilizer granules, coconut fiber, and SAP granules are combined into a composite felt. Next, a layer of polypropylene mesh is placed on the upper and lower surfaces of the four corners of the formed composite felt. Using a sewing machine with high-strength biodegradable sewing thread such as polylactic acid (PLA), a crisscross stitch is created at a fixed interval (e.g., 50mm x 50mm). Finally, the geogrid 201 is placed on top of the composite felt body and the upper and lower polypropylene mesh structure formed above. The surface of the geogrid and the polypropylene mesh are melted by the thermal bonding process to complete the production of the composite pad 2. In addition, through holes corresponding to the anchor holes 105 need to be opened at the four corners of the composite pad 2 so that the anchor rods 3 can pass through. In addition, the biodegradability period of the coconut fiber pad can be selected and determined according to the growth cycle of the seeds in the planting bag 5. For example, if herbaceous plants are selected, the degradation period can be shortened by adding straw fiber or degradation additives. If shrubs or trees are selected, suitable holes need to be pre-drilled in the middle of the geogrid so that the shrubs can pass through after they grow. At the same time, pure coconut fiber pads are selected so that the biodegradability period can be maintained at 1-3 years.
[0051] Anchor bolt 3 Figures 3-5 As shown, the structure consists of a hollow rod 301, a grout stop plug 303, a gasket 304, a nut 305, and a retaining ring 306. The hollow rod 301 is a high-strength alloy steel pipe with external threads. Multiple sets of grouting holes 302 are axially arranged on the outer surface of its lower half. Furthermore, an isolation device is installed on the hollow rod 301 to divide it into an ecological anchoring section and a grouting anchoring section along its length. This isolation device is pre-welded to the hollow rod 301. The retaining ring 306 on the outer wall and the grout stop plug 303 sleeved on the outside of the hollow rod 301 and located below the retaining ring 306 constitute the structure. The outer diameter of the retaining ring 306 is equal to that of the anchor hole 105. Its welding position is determined according to the depth of the hollow rod 301 extending into the slope 6 and the height of the anchor hole 105. The pad 304 is sleeved on the outside of the hollow rod 301 and located at the upper end of the composite pad 2. The pad 304 can be fastened and pressed onto the composite pad 2 by the nut 305.
[0052] More specifically, the ecological anchoring section is located in the part of the anchoring hole 105 above the retaining ring 306. The annular space in this part is not grouted, but backfilled with vegetation matrix 4. The grouted anchoring section is the section located below the retaining ring 306 and extending into the interior of the slope 6. Cement grout is pressed into this section through the hollow rod 301 and the grouting hole 302, forming a firm mechanical anchor with the surrounding stable rock mass. Moreover, the grout stop plug 303 is pushed towards the retaining ring 306 under the pressure of the grout and forms an effective seal, preventing the grout from flowing into the ecological anchoring section.
[0053] The vegetative substrate 4 is composed of lightweight aggregate, organic matter, water-retaining agent, and slow-release fertilizer. The lightweight aggregate is made of materials such as expanded perlite and vermiculite to ensure good drainage and aeration. The organic matter is made of materials such as peat, humus, or compost to provide basic nutrients and improve soil structure. In this embodiment, the organic matter content is controlled at 8%–16%. The water-retaining agent is additional SAP particles to enhance the water retention capacity of the substrate. The slow-release fertilizer is used to provide long-lasting nutrition. In this embodiment, the nitrogen, phosphorus, and potassium ratio is N:P:K = 1:0.5:0.8. Moreover, the porosity of the vegetative substrate 4 is set at 50%–65%, and the bulk density is controlled at 1.3–1.7 g / cm3 to facilitate root penetration while maintaining necessary structural stability.
[0054] By setting the grout stopper 303 and the retaining ring 306, the anchor rod 3 is divided into two parts: an ecological anchoring section and a grouting anchoring section. The area where the anchor rod 3 extends into the slope 6 is the grouting anchoring section, and the part located in the anchoring hole 105 is the ecological anchoring section. The space between the anchoring hole 105 and the outer wall of the anchor rod 3 is filled with vegetation substrate. The annular space of this hole section is backfilled with vegetation substrate 4, which is conducive to plant growth. At the same time, since the root guidance channel 106 on the side wall is connected to the anchoring hole 105, the plant roots located inside the receiving cavity 102 will be naturally guided into the loose and fertile vegetation substrate 4 around the anchor rod 3 in the process of searching for water and nutrients. Thus, the plant roots will wrap around and fix the anchor rod 3 and the prefabricated anchoring frame 1. In addition, the connection channel 1062 and the lower end face of the prefabricated anchoring frame 1 are connected. The branch channels 1062 set between them can wrap and fix the plant roots to the prefabricated anchor frame 1, and the root guide channel 107 set on the bottom plate of the receiving cavity 102 can make the plant roots wrap and fix to the grid-like bottom plate and extend into the interior of the slope 6. Thus, the overall structure forms a root network with a wide range and great depth, transforming the originally purely passive mechanical anchoring system into a continuously growing and self-reinforcing bio-mechanical complex. Over time, the interweaving effect between the deep root network and the prefabricated anchor frame 1, anchor rod 3 and the soil of the slope 6 will greatly improve the shear strength and overall stability of the soil, and share the load with the anchor rod 3. The stability of the slope 6 is no longer a static value, but dynamically increases with the maturity of the ecosystem.
[0055] The construction steps for this device are as follows:
[0056] a. Slope preparation: The surface of slope 6 is smoothed according to the design requirements. Loose soil, loose rocks and weeds are removed from the slope. If necessary, the slope is compacted to provide a stable base for the installation of precast anchor frames 1.
[0057] b. Frame layout: First, pour a certain width and length of lower concrete protection 7 at the lower end of slope 6. Then, hoist the prefabricated anchor frames 1 to the slope surface using a lifting device. Starting from the slope toe near the lower concrete protection 7, the frames are laid out from bottom to top. Each prefabricated anchor frame 1 is arranged in a grid pattern according to the spacing required by the design drawings. During installation, the anchor spikes 109 are used to press the frames onto the surface of slope 6 to achieve initial positioning.
[0058] c. Drilling: Using a drilling rig, a self-propelled hollow rod 301 pre-assembled with a drill bit, grout stop plug 303 and retaining ring 306 is driven to pass through the anchoring hole 105 of the prefabricated anchoring frame 1 and drill into the interior of the slope 6 until the designed total depth is reached (this depth must pass through the potential sliding surface and enter the stable soil layer by no less than 3-4 meters).
[0059] d. Planting substrate backfilling and planting: Fill the annular space between the anchor holes 105 and above the retaining ring 306 of the anchor rod 3 with the specially made planting substrate 4 until it is full. Then, place the composite pad 2 into the groove 101. The pad 304 is fitted on the outside of the hollow rod body 301 and tightened to the upper end face of the composite pad 2 with the nut 305. Finally, place the planting bag 5 pre-filled with substrate and plant seeds into the receiving cavity 102.
[0060] e. Grouting of anchorage section: High-strength cement grout is injected into the slope 6 through the hollow rod 301 by the grouting pump to form a grouting anchorage section. The grout stop plug 303, under the obstruction of the retaining ring 306, ensures that the grout is confined within the grouting anchorage section until the section is fully grouted. If it is a prestressed anchor design, tensioning and locking are carried out after the grout reaches a certain strength.
[0061] f. Finishing: Finally, pour concrete protection 9 on the top of the laid anchor frame, then clean the site. Spray greening can be carried out on the exposed slope between the precast anchor frames 1 to form a complete vegetation cover. After the construction is completed, carry out the first irrigation to activate the water retention function of the SAP particles.
[0062] After the installation of this device is completed, it will appear as follows: Figure 3 As shown, the upper surface of the composite pad 2 is flush with or slightly higher than the upper surface of the precast anchoring frame 1, the upper end of the grout stop plug 303 is pressed against the lower end of the retaining ring 306, and the outer wall of the grout stop plug 303 is tightly fitted with the inner wall of the anchoring hole 105.
[0063] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
