Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and more specifically, to a replaceable honeycomb vegetation module system and method for ecological slope protection of riverbanks. Background Technology

[0002] Riverbank ecological slope protection is an important component of water conservancy projects. It not only needs to provide slope protection and erosion resistance but also a suitable environment for vegetation growth to achieve the synergistic goals of ecological restoration and long-term stability. Currently, common riverbank ecological slope protection technologies mainly include methods such as planting bag stacking, geocell assembly, and filling planting substrate within rigid concrete frames. While these methods can achieve basic slope protection and greening functions, their structure and function remain fixed after construction and cannot be dynamically adjusted according to the natural succession process of the riverbank ecosystem.

[0003] However, from construction completion to stable maturity, riparian ecosystems undergo a succession process, evolving from bare slopes, pioneer herbs, mixed shrubs and grasses, to mature tree communities. The requirements for slope roughness, planting substrate characteristics, root anchoring capacity, and erosion resistance differ significantly at each stage. Existing one-time prefabricated slope protection structures cannot meet these dynamic needs, easily leading to insufficient erosion resistance in the early stages or restricted vegetation growth later. Furthermore, when the slope protection function no longer meets later requirements, existing technologies necessitate complete demolition and reconstruction, resulting not only in resource waste and high costs but also secondary disturbance to the ecological environment. Simultaneously, existing modular slope protection units are mostly independent, separate structures, hindering the interpenetration of plant roots between modules and making it difficult to form a reinforced ecological network, thus affecting the long-term stability of the slope protection.

[0004] Therefore, there is an urgent need to provide a replaceable honeycomb vegetation module system and method for riverbank ecological slope protection to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a replaceable honeycomb vegetation module system and method for riverbank ecological slope protection, so as to solve the problem that the existing technology cannot adapt to the natural succession rhythm of riverbank ecosystems in a low-cost and low-interference manner.

[0006] The objective of this invention can be achieved through the following technical solutions: A replaceable honeycomb vegetation module system for riverbank ecological slope protection includes: Multiple unit frames, each unit frame being a regular hexagonal prism cylindrical structure, are spliced ​​together by sidewall connection structures to form a honeycomb-shaped integral slope protection surface layer; Multiple functional core boxes, each of which is an independent container that matches the shape of the internal cavity of the unit frame, and each functional core box can be independently inserted into or pulled out of the unit frame; The wall of the functional core box is designed to be penetrated by plant roots or to have root-penetrating holes.

[0007] Furthermore, the inner sidewall of the unit frame is provided with a vertical sliding groove, and an elastic anti-detachment block is provided in the sliding groove; The outer side wall of the functional core box is provided with a protruding ridge that slides with the slide groove, and the protruding ridge is provided with a slot that engages with the anti-detachment block.

[0008] Furthermore, the sidewall connection structure includes: The connecting tenon is provided on the side wall of the unit frame, and the connecting groove is provided on the adjacent side wall and matches the shape of the connecting tenon; The adjacent unit frames are mechanically interlocked by the engagement of the connecting tenon and the connecting groove.

[0009] Furthermore, the connecting tenon is a trapezoidal tenon, and the connecting groove is a trapezoidal groove that matches the trapezoidal tenon.

[0010] Furthermore, the functional core box, depending on the internal filling material, is configured to be suitable for different ecological stages, including at least: A core box for promoting sludge production, primarily composed of coarse-grained skeleton materials; A plant-based core box with a fiber nutrient substrate as its main component; And a stable core box mainly composed of biochar mixed materials.

[0011] Furthermore, it also includes anchors for anchoring the unit frame to the slope with its axis perpendicular to the slope.

[0012] Furthermore, the anchor is an anchor rod, and the unit frame has a reserved hole for the anchor rod to pass through.

[0013] Furthermore, the box wall of the functional core box is made of reinforced plant fiber felt, and the root-penetrating holes are evenly opened on the side walls and bottom of the functional core box.

[0014] Furthermore, the elastic anti-detachment block is formed by partially thinning the side wall of the unit frame, and emits a positioning prompt sound when the anti-detachment block engages with the slot.

[0015] Compared with the prior art, the beneficial effects of the system provided by the present invention are as follows: 1. By setting up multiple unit frames and independently replaceable functional core boxes, the appropriate type of functional core box can be selected for replacement according to different succession stages of the riverbank ecosystem, so that the engineering and ecological functions of the slope protection can be adjusted as needed, truly realizing the coordinated evolution of artificial engineering and natural ecological processes, and solving the technical problem that the existing slope protection functions are fixed and cannot adapt to the needs of ecological succession. 2. Upgrading the slope protection function only requires replacing the functional core box, avoiding the need for complete structural reconstruction and significantly reducing long-term maintenance and renovation costs. At the same time, the standardized functional core box facilitates factory production and transportation, solving the problem of existing technologies requiring complete dismantling and reconstruction for later modifications, resulting in significant resource waste. 3. The unit frame is spliced ​​into a honeycomb-shaped overall load-bearing structure through the side wall connection structure. The box wall of the functional core box adopts a structure that can be penetrated by plant roots or has root-penetrating holes, allowing plant roots to grow freely between modules, connecting discrete modules into an organic whole reinforced by plant roots, which greatly improves the long-term biomechanical stability of the slope and solves the problem that the roots of existing modular slope protection are difficult to penetrate and cannot form an overall reinforcement network. 4. The combination of the sliding groove and the anti-detachment block ensures that the functional core box will not fall off unexpectedly under complex hydraulic conditions. At the same time, the positioning indication design of the block and groove facilitates installation confirmation and solves the problem of insufficient reliability of existing replaceable modules in riverbank environments.

[0016] On the other hand, the present invention also provides a method for dynamic adjustment of riverbank ecological slope protection, comprising the following steps: Monitoring and diagnosing the stage of ecological succession of riverbank slopes; Based on the diagnostic results, determine the types of functional core boxes required for the current slope and those expected to be required in the next stage; During periods of low plant growth activity, functional core boxes that do not meet the needs of the current or next stage are removed from the unit frame. Insert the functional core box that meets the requirements of the target stage into the corresponding unit frame.

[0017] Understandably, the beneficial effects of this method are the same as those of the system described above, and will not be repeated here. Attached Figure Description

[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] See Figures 1 to 5 This invention provides a replaceable honeycomb vegetation module system and method for riverbank ecological slope protection, including multiple unit frames 100 and multiple functional core boxes 200.

[0021] See Figure 1 and Figure 2It is known that the unit frame 100 is a regular hexagonal prism cylindrical structure, integrally cast from concrete. Multiple unit frames 100 are spliced ​​together through sidewall connection structures to form a honeycomb-shaped integral slope protection surface layer. The functional core box 200 is an independent container matching the shape of the inner cavity of the unit frame 100. The functional core box 200 can be independently inserted into or removed from the unit frame 100. The box wall of the functional core box 200 has a structure that allows plant roots to penetrate or has root-penetrating holes.

[0022] The inner sidewall of the unit frame is provided with a vertical sliding groove, and an elastic anti-detachment block is provided in the sliding groove; the outer sidewall of the functional core box is provided with a protruding ridge that slides with the sliding groove, and a groove on the protruding ridge that engages with the anti-detachment block. The sidewall connection structure includes: The connecting tenon is provided on the side wall of the unit frame, and the connecting groove is provided on the adjacent side wall and matches the shape of the connecting tenon; The adjacent unit frames are mechanically interlocked by the engagement of the connecting tenon and the connecting groove. The connecting tenon is a trapezoidal tenon, and the connecting groove is a trapezoidal groove that matches the trapezoidal tenon.

[0023] It should be noted that the inner sidewall of the unit frame 100 is provided with at least two vertical grooves 110, and the lower middle part of the grooves 110 is provided with an inwardly protruding elastic anti-detachment block 120. Preferably, the elastic anti-detachment block 120 is formed by partially thinning the sidewall of the unit frame 100, so that it has a certain elastic deformation capability.

[0024] On the six side walls of the unit frame 100, at least three opposite side walls are provided with vertical connecting tenons 130, and the remaining side walls are provided with connecting grooves 140 that match the shape of the connecting tenons 130. Adjacent unit frames 100 achieve mechanical interlocking through the engagement of the connecting tenons 130 and the connecting grooves 140. Preferably, the connecting tenons 130 are trapezoidal tenons, and the connecting grooves 140 are trapezoidal grooves that match the trapezoidal tenons, achieving a tight engagement through hammering during assembly.

[0025] like Figure 6 As shown, multiple unit frames 100 can be spliced ​​into a stable honeycomb-shaped integral slope protection surface layer through the interlocking of the tenons and grooves.

[0026] The functional core box has a wall made of reinforced plant fiber felt, and the root-penetrating holes are evenly distributed on the side walls and bottom of the functional core box. Depending on the internal filling material, the functional core box can be configured to suit different ecological stages, including at least: a silt-promoting core box mainly composed of coarse-particle skeleton materials; a vegetative core box mainly composed of fiber nutrient substrates; and a stabilizing core box mainly composed of biochar mixtures.

[0027] It should be noted that, see Figure 3 , Figure 4 The functional core box 200 is an independent container that matches the shape of the inner cavity of the unit frame 100. The outer wall of the functional core box 200 is provided with a protruding rib 210 that slides with the sliding groove 110, and the protruding rib 210 is provided with a slot corresponding to the position of the anti-detachment block 120.

[0028] The functional core box 200 has a box wall made of reinforced plant fiber felt that can be penetrated by plant roots, and a large number of root-penetrating holes 230 are evenly opened on its side walls and bottom. Preferably, the diameter of the root-penetrating holes 230 is about 5 mm to allow plant roots to penetrate.

[0029] The functional core box 200, depending on the internal filling material, is configured to be suitable for different ecological stages, including at least: Type A siltation-promoting skeleton core box: The filling material is large-diameter crushed stone or gravel, forming a large-pore skeleton, used to increase slope roughness and dissipate energy to promote siltation in the early stage of slope protection; Type B vegetation substrate core box: The filling material is a lightweight nutrient substrate mixed with coconut fiber, water-retaining agent, slow-release fertilizer and local topsoil, used in the germination and rapid growth stage of plants. Type C stabilizing and improving core box: The filling material is a mixture of biochar, lightweight ceramsite and clay, which is used to improve soil fertility, carbon sequestration capacity and overall corrosion resistance in the later stage.

[0030] It also includes anchors for securing the unit frame to the slope with its axis perpendicular to the slope. The anchors are anchor rods, and the unit frame has pre-drilled holes for the anchor rods to pass through. The elastic anti-detachment block is formed by partially thinning the side wall of the unit frame, and emits a positioning sound when the anti-detachment block engages with the slot.

[0031] It should be noted that, as Figure 5 As shown, during assembly, the protruding ridge 210 of the functional core box 200 is aligned with the upper opening of the sliding groove 110 of the unit frame 100 and inserted vertically downwards. When the top of the functional core box 200 approaches the top surface of the unit frame 100, the inclined surface of the protruding ridge 210 will press the elastic anti-detachment block 120 outwards slightly until the slot moves to the position of the anti-detachment block 120. The anti-detachment block 120 rebounds under its own elasticity and locks into the slot. At this time, a crisp "click" sound can be heard, indicating that the assembly is in place and locked.

[0032] During disassembly, insert a special tool (such as a flat pry bar) into the gap between the functional core box 200 and the unit frame 100 from the top, and slightly expand the elastic anti-disengagement block 120 to smoothly lift out the functional core box 200.

[0033] Preferably, the system further includes anchors for anchoring the unit frame 100 to the slope. The anchors are anchor rods, and the unit frame 100 has pre-drilled holes for the anchor rods to pass through.

[0034] The unit frame 100 has a pre-drilled hole on its side wall, which is provided through the side wall of the unit frame 100 for anchors to pass through. After passing through the pre-drilled hole, the anchor is inserted into the solid soil of the slope, anchoring the unit frame 100 to the slope.

[0035] The following describes the installation method of the replaceable honeycomb vegetation module system for riverbank ecological slope protection provided by this invention, with specific construction steps as an example.

[0036] S1: Positioning and layout. Use a total station to set control stakes along the slope protection axis, and mark the top of the slope, the toe of the slope, and the 100mm splicing boundary of the unit frame to ensure that the frame is arranged straight.

[0037] S2: Mortise and tenon joint. Install unit frames 100 row by row from the foot of the slope to the top of the slope. Adjacent frames are connected by trapezoidal tenons 130 and connecting grooves 140. When splicing, use a rubber mallet to tap the side wall of the frame to ensure that the tenons 130 are fully embedded in the connecting grooves 140, forming a honeycomb-like overall structure, which improves the resistance to water erosion.

[0038] S3: Anchoring of key parts. At the toe and top of the slope, one anchor rod is installed for every three unit frames 100. The anchor rod is inserted into the solid soil of the slope through the reserved hole of the unit frame 100 and fixed at the top with a nut, forming an anchoring system of "frame-anchor rod-soil" to prevent the frame from slipping due to scouring at the toe of the slope.

[0039] On the other hand, this application also provides a method for dynamic adjustment of riverbank ecological slope protection, comprising the following steps: Monitoring and diagnosing the stage of ecological succession of riverbank slopes; Based on the diagnostic results, determine the types of functional core boxes required for the current slope and those expected to be required in the next stage; During periods of low plant growth activity, functional core boxes that do not meet the needs of the current or next stage are removed from the unit frame. Insert the functional core box that meets the requirements of the target stage into the corresponding unit frame.

[0040] The following section explains the dynamic adjustment method of the replaceable honeycomb vegetation module system used for riverbank ecological slope protection, taking into account the ecological succession stage.

[0041] Initial Stage (early stages after project completion, years 0-1): The slope is exposed, and the main challenge is preventing soil erosion. At this stage, type A silt-promoting skeleton core boxes are inserted into all unit frames 100. Their large-diameter filler forms a rough surface, effectively disrupting the water flow along the bank, promoting siltation, and providing an attachment base for plant seeds.

[0042] Mid-term (herbaceous plant establishment and growth stage, years 1-3): Initial siltation and natural seed drop have occurred on the slope. Type A core boxes are gradually replaced with Type B vegetation substrate core boxes. Their high-quality mixed substrate provides an excellent environment of water, fertilizer, and air for the germination and rapid growth of herbaceous plants, quickly forming a green cover.

[0043] Later stage (woody plant invasion and community stabilization stage, after year 3): Shrub seedlings begin to appear in the herbaceous community. Gradually replace the type B core box with the type C stabilizing and improving core box. Biochar provides long-term carbon sequestration and microbial habitat, improving soil health; its mixed matrix is ​​more conducive to the development and anchoring of deep root systems of shrubs and trees, enhancing the ecosystem hierarchy and the ultimate stability of the slope protection structure.

[0044] The replacement work is carried out in late autumn or early winter (during the plant's dormancy period). Workers can easily insert and remove the core boxes using specialized tools, minimizing disturbance to the existing vegetation. The replacement process only involves specific locations and does not affect the overall slope stability or protective function.

[0045] The specific replacement steps include: Monitoring and diagnosing the stage of ecological succession of riverbank slopes; Based on the diagnostic results, the required type of functional core box 200 for the current slope and the expected type for the next stage were determined; During the low-activity period of plant growth, after temporarily unlocking the anti-loosening block 120 using a special tool, the functional core box 200 that does not meet the current or next stage requirements is pulled out from the unit frame 100. Insert the functional core box 200 that meets the requirements of the target stage into the corresponding unit frame 100.

[0046] The replacement of the functional core box 200 follows a progressive order from the type A silt-promoting core box to the type B vegetation-promoting core box and then to the type C stabilizing core box, in order to match the natural succession process of the riparian ecosystem from bare, herbaceous cover to woody stability.

[0047] It is understood that the bottom of the unit frame 100 may also have appropriately sized root-penetrating holes to further enhance the downward growth of plant roots and the overall reinforcement effect. The dimensions of the unit frame 100 and the functional core box 200 can be adjusted according to actual engineering needs to adapt to riverbanks with different slopes and hydraulic conditions.
