Description

Technical Field

[0001] This invention relates to the field of slope protection, and more specifically to a device for guiding plant roots and strengthening soil erosion resistance on highway slopes in high-altitude and cold regions. Background Technology

[0002] Some areas in Heilongjiang Province, my country, suffer from severe wind and sand erosion. After highway construction, the slopes on both sides are highly susceptible to soil erosion. Furthermore, this section of the road is located in a high-latitude, cold region characterized by low temperatures, low rainfall, short growing seasons, low biodiversity, and a relatively fragile ecosystem. This significantly increases the difficulty of ecological restoration after vegetation destruction along the highway. The selection of wind-resistant plants needs to consider enhancing soil erosion resistance through root systems. Plant roots enhance soil erosion resistance primarily through their entanglement and consolidation, resulting in a higher water-stability structure and erosion resistance in the soil, making it less susceptible to runoff. The direct effect of roots in improving soil erosion resistance is increased soil erosion capacity; its indirect effect is enhanced soil permeability. The physical properties of the erosion-resistant soil structure created by roots are the material basis for improving soil erosion resistance.

[0003] Existing technologies primarily focus on physical protection, such as simply blocking erosion, without designing suitable structures based on the growth characteristics of plants in high-altitude and cold regions. For example, the topsoil layer in hydroseeding is easily blown away by strong winds or washed away by rainwater; the three-dimensional mesh is prone to aging and damage under strong ultraviolet radiation; and the soil inside the planting bags freezes at low temperatures, inhibiting root development. Ultimately, this results in short slope protection cycles and low ecological restoration rates, failing to achieve a long-term unified approach of "protection-ecology-stability." There is an urgent need for a technical solution that adapts to the environment of high-altitude and cold regions, guides root growth, strengthens soil erosion resistance, and also considers ecological restoration to overcome current technological bottlenecks. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the present invention provides a plant root guiding and soil erosion strengthening device for highway slopes in high-altitude and cold regions. The beneficial effects are that it can increase the contact area and friction between the roots and the soil, and significantly enhance the entanglement and consolidation ability between the roots and the soil.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A device for guiding plant roots and strengthening soil erosion resistance on highway slopes in high-altitude and cold regions includes a grid frame with a hollow core. At each of the four corners of the grid frame, there are insertion components that can be inserted into the soil. A circular ring frame is rotatably connected to the grid frame. Two connectors are symmetrically fixed to the inner side of the circular ring frame. A spiral tube passing through the core of the grid frame is fixed to each of the two connectors. Multiple guide holes II that communicate with the interior of the spiral tubes are evenly opened on the inner side of the spiral tubes.

[0007] Two straight pipes are symmetrically inserted on the grid frame, and pipe supports are fixed to both straight pipes. A circular frame is rotatably connected between the two pipe supports.

[0008] The beneficial effects of this invention are as follows:

[0009] Multiple flow-guiding holes II are evenly distributed on the inner surface of the two spiral tubes and communicate with their interior. Nutrient solution or rooting agent seeps out evenly through the multiple flow-guiding holes II on the inner surface, allowing the roots to capture the nutrient solution and promote their growth downward along the direction of the spiral tubes. This design guides the roots to grow in a spiral shape, greatly increasing the contact area and friction between the roots and the soil, significantly enhancing the ability of the roots to entwine and consolidate with the soil, solving the problems of low rainfall and poor soil in high-altitude and cold regions, and promoting rapid root development.

Detailed Implementation

[0020] See Figures 1 to 6 The diagram shows an embodiment of the present invention that guides the roots to grow along a spiral trajectory.

[0021] A device for guiding plant roots and strengthening soil erosion resistance on highway slopes in high-altitude and cold regions includes a grid frame 101 with a hollow core. At each of the four corners of the grid frame 101, there are insertion components that can be inserted into the soil. A circular ring frame 201 is rotatably connected to the grid frame 101. Two connectors 301 are symmetrically fixed to the inner side of the circular ring frame 201. A spiral tube 302 passing through the core of the grid frame 101 is fixed to each of the two connectors 301. Multiple guide holes II 304 communicating with the interior are evenly opened on the inner side of the two spiral tubes 302.

[0022] Place the grid frame 101 at the location on the slope where planting is desired. Then, insert the four corner components of the grid frame 101 into the slope soil to securely anchor the device, preventing displacement due to wind, runoff, or freeze-thaw cycles in cold regions, while ensuring soil aeration. The hollow core design provides installation space for the two helical tubes 302. After the grid frame 101 is anchored, manually rotate the ring frame 201. The ring frame 201 rotates the two helical tubes 302, causing them to spiral into the soil.

[0023] The spiral structure of the two spiral tubes 302 provides natural entanglement support for plant roots, guiding the roots to extend longitudinally and laterally along the spiral trajectory, forming an interwoven root network and enhancing soil consolidation.

[0024] Nutrient solution or rooting agent can also be injected from the top of the two spiral tubes 302. The nutrient solution or rooting agent will seep out evenly through multiple guide holes II 304 on the inner side. The distribution of multiple guide holes II 304 can accurately replenish the root system along the root guidance path, so that the root system can capture the nutrient solution and promote its growth downward along the direction of the spiral tube 302. This design guides the root system to grow into a spiral shape, which greatly increases the contact area and friction between the root system and the soil, significantly enhances the ability of the root system to entwine and consolidate with the soil, solves the problem of low rainfall and poor soil in high-altitude and cold regions, and promotes rapid root development.

[0025] The spiral tube 302 supplies water and nutrients to the deep soil, avoiding localized drought or nutrient concentration, ensuring a uniform and stable growth environment for the roots along the tube, further enhancing the root system's binding and consolidation effect on the soil, and strengthening the soil's consolidation and erosion resistance.

[0026] After the plant roots have grown and matured, when it is time to remove the device, manually rotate the circular frame 201 in the opposite direction. The circular frame 201 drives the two spiral tubes 302 to rotate in the opposite direction and unscrew from the soil. Once the two spiral tubes 302 are removed from the soil, the grid frame 101 can be disassembled. Because the plant roots are spirally intertwined with the soil, the spiral tubes 302 will not pull or damage the roots when they are unscrewed from the soil.

[0027] See Figure 5 and 6 The diagram shows an embodiment of the present invention incorporating water and nutrients.

[0028] Both connectors 301 are fixedly connected with tube heads 303 that communicate with the spiral tube 302;

[0029] The nozzle 303 serves as an interface for supplying nutrient solution or rooting agent, allowing for convenient injection of water and nutrients into the spiral tube 302, meeting the convenience requirements of on-site construction in high-altitude and cold regions. The injected substances quickly enter the spiral tube 302 through the nozzle 303, flow along the tube body, and evenly permeate into the surrounding soil through multiple guide holes II 304, ensuring precise supply of substances needed for root growth and avoiding waste.

[0030] See Figure 3 and 4 A schematic diagram of an embodiment of the device for improving overall stability according to the present invention is shown;

[0031] Two straight pipes 203 are symmetrically inserted on the grid frame 101, and pipe supports 202 are fixedly connected to both straight pipes 203. The circular frame 201 is rotatably connected between the two pipe supports 202.

[0032] The pipe frame 202 fixed to the straight pipe 203 provides rotational support for the circular frame 201, thereby enabling the two straight pipes 203 to rotate synchronously and be screwed into the soil by rotating the circular frame 201.

[0033] Initially, after the grid frame 101 is placed on the soil surface and anchored, two straight tubes 203 are inserted into the grid frame 101. At this time, the two spiral tubes 302 are located at the upper end of the grid frame 101. When the ring frame 201 is manually rotated, the two spiral tubes 302 are driven into the soil. The two spiral tubes 302 will drive the two straight tubes 203 downward into the soil. The two straight tubes 203 not only enhance the overall rigidity of the grid frame 101 and prevent structural deformation caused by strong winds or soil loosening in cold regions, but also penetrate deep into the soil through their own length to form auxiliary fixing points and improve the overall stability of the device.

[0034] The plug-in installation of the straight pipe 203 facilitates on-site disassembly and position adjustment, improving the adaptability of the device to different slope conditions.

[0035] Manually rotate the circular frame 201 in the opposite direction. The circular frame 201 drives the two spiral tubes 302 to rotate in the opposite direction and spin out of the soil. At the same time, the circular frame 201 drives the two straight tubes 203 to be pulled upward from the soil through the two tube frames 202.

[0036] See Figure 4 The diagram shows an embodiment of a further improvement in soil erosion resistance and water-stable structure according to the present invention;

[0037] The two straight pipes 203 are provided with a plurality of guide holes I204 communicating with their interiors;

[0038] The guide hole I204 precisely replenishes nutrients along the root-guided path, while the straight pipe 203 and guide hole I204 work together to ensure balanced overall soil nutrients and suitable moisture levels on the slope. The guide holes I204 are vertically and evenly distributed to prevent localized water accumulation and to prevent damage to the roots or nutrient deficiencies caused by freezing temperatures in high-altitude areas. This promotes root growth not only along the extension direction of the spiral pipe 302 but also laterally spreading towards the straight pipe 203, forming a comprehensive root network that further enhances soil erosion resistance and water stability.

[0039] See Figure 1 , 2 Figures 7 and 8 show schematic diagrams of an embodiment of guided seeding of plants according to the present invention;

[0040] A right-angle bracket 402 is fixedly connected to each of the two pipe supports 202, and an internally threaded ring bracket 401 is fixedly connected between the two right-angle brackets 402. The right-angle bracket 402 is threadedly connected to the internally threaded ring bracket 401.

[0041] When the circular ring frame 201 is manually rotated, the two spiral tubes 302 are screwed into the soil. The part of the right-angle frame 402 located at the lower end of the inner threaded ring frame 401 is inserted into the soil surface. The right-angle frame 402 located in the center of the grid frame 101 is used for precise seed placement, avoiding seed placement deviation. This allows the roots to grow along the two spiral tubes 302 after the seeds germinate.

[0042] Furthermore, the seedlings that are beginning to take shape can be inserted into the right-angle frame 402, which can provide auxiliary support for the seedlings.

[0043] The threaded connection between the internal threaded ring frame 401 and the right-angle frame 402 allows the right-angle frame 402 to be detached. When the seedlings grow to the point where they no longer need support, usually 3 to 6 months later, the right-angle frame 402 can be rotated off the internal threaded ring frame 401 to prevent the right-angle frame 402 from blocking sunlight or hindering root expansion. If the seeds do not germinate after sowing, the right-angle frame 402 can be removed for re-sowing.

[0044] See Figure 8 A schematic diagram of an embodiment of auxiliary support for plant stem diameter according to the present invention is shown;

[0045] The right-angle frame 402 is symmetrically and detachably connected to two side frames 404 by screws. Each side frame 404 has a plate 405 inserted into it. Each plate 405 has a fixing bracket 406 fixed to its inner side. Each fixing bracket 406 is rotatably connected to a screw 407. The two screws 407 are threadedly connected to the two side frames 404 respectively.

[0046] Manually rotating the two screws 407 causes the two fixing brackets 406 to come closer together and fit against the plant stem diameter. Compared to single support or rope binding, this double-sided support can evenly distribute the external forces on the stem diameter, such as strong winds of level 8 to 10 in high-altitude cold regions, the impact of slope runoff, and the traction force of soil loosening caused by freeze-thaw cycles, preventing the stem diameter from bending or falling over due to unilateral force. This solves the core problem of unstable root systems and susceptibility to extreme weather after transplanting plants in high-altitude cold regions.

[0047] Rotating screw 407 creates a buffer gap between the inner side of the fixing bracket 406 and the stem diameter, preventing direct rigid compression of the plant stem. This prevents damage to the bark due to excessive clamping force and accommodates the radial thickening required during the plant's growing season. As the plant stem diameter thickens, simply rotating screw 407 in the opposite direction loosens the fixing bracket without disassembling the entire component, thus avoiding disturbance to the soil around the roots. Once the plant roots are fully established and the stem diameter is sufficient to withstand external forces, the fixing bracket can be removed by disassembling the side frame 404 without affecting the plant's subsequent natural growth.

[0048] Multiple ventilation holes 408 are provided on the two fixing frames 406; this ensures the circulation of air between the plant stem and the plant, on the one hand preventing the stem from becoming stuffy and damp due to the fixing frame wrapping, and on the other hand promoting the respiration of the stem bark and enhancing the plant's own resistance.

[0049] See Figure 1 and 3 A schematic diagram of an embodiment of the grounding assembly according to the present invention is shown;

[0050] The four corners of the grid frame 101 are all fixed with inner spiral hole seats 102, and the grounding assembly includes a grounding nail 104 that passes through the inner spiral hole seat 102, and a screwing rod 106 is fixed to the upper end of the grounding nail 104.

[0051] The inner spiral holes 102 at the four corners of the grid frame 101 provide precise installation channels for the ground anchors 104, ensuring that the ground anchors 104 are inserted vertically into the soil and avoiding insufficient fixing force due to tilting. The screw rod 106 at the upper end of the ground anchor 104 can be rotated manually, adapting to the on-site construction conditions of the slope. Rotating the screw rod 106 drives the ground anchor 104 deeper into the soil. Its sufficient length ensures the anchoring depth, resisting surface soil erosion or freeze-thaw loosening in cold regions, providing stable support for the grid frame 101, ensuring the foundation stability of the entire device, and preventing root guidance and soil erosion resistance from being affected by foundation loosening.

[0052] See Figure 3 A schematic diagram of an embodiment of the invention for preventing the ground nail 104 from loosening is shown.

[0053] The grounding assembly also includes a spiral blade 105 fixed to the grounding nail 104, and the spiral blade 105 is spirally connected to the inner spiral hole seat 102.

[0054] When the screw rod 106 is rotated, the spiral structure of the spiral blade 105 converts the rotational force into a downward drilling force, effectively reducing the resistance of the ground stake 104 when it is inserted into the compacted soil or frozen layer in cold regions, and improving installation efficiency. After the spiral blade 105 drills into the soil, it greatly increases the contact area with the soil, forming a fixing effect similar to a "spiral anchor", enhancing the pull-out and torsional resistance of the ground stake 104, preventing the ground stake 104 from loosening due to freeze-thaw cycles or runoff erosion in cold regions, further consolidating the installation stability of the grid frame 101, and ensuring the long-term effective operation of the device.

[0055] See Figure 3 A schematic diagram of an embodiment in which an additional fixing rod can be inserted according to the present invention is shown;

[0056] The grid frame 101 has a plurality of insertion holes 103 for inserting fixing rods.

[0057] The insertion holes 103 arranged around the grid frame 101 provide flexible expansion and reinforcement options for the device. When the slope is steep, the soil stability is extremely poor, or extreme weather such as strong winds or heavy rain occurs, additional fixing rods can be inserted through the insertion holes 103 and driven deep into the soil to increase the number of fixing points and disperse the runoff impact and wind force on the device. The surrounding design allows the installation position of the fixing rods to be selected according to the actual stress characteristics of the slope, avoiding excessive local stress on the grid frame 101 that could lead to deformation or displacement, ensuring the stability of core components such as the connector 301 and straight pipe 203, and ensuring the continuous effectiveness of root guidance and soil erosion resistance enhancement.

[0058] See Figure 3 and 6 The diagram shows an embodiment of ensuring unobstructed flow inside a pipe according to the present invention.

[0059] Both the pipe head 303 and the straight pipe 203 have pipe caps threadedly connected to their ends;

[0060] The structural design of the pipe head 303 provides a foundation for the pipe cap, ensuring the cleanliness of the inside of the connector 301 and preventing blockage.

[0061] In high-altitude and cold regions, the soil contains a lot of sand, gravel, and debris. When there is no need to inject material into the straight pipe 203 and the spiral pipe 302, the pipe cap seals the port to prevent soil particles, sand, gravel, and debris from entering the pipe and blocking the guide hole I 204 and guide hole II 304, thus ensuring unobstructed flow inside the pipeline and avoiding affecting subsequent replenishment and infiltration effects.

[0062] The threaded connection facilitates disassembly and does not affect subsequent material resupply operations, balancing protection and practicality.
