Description

Technical Field

[0001] The present invention relates to the fields of civil engineering and slope protection, and in particular to a 3D printed gradient strength slope protection device and a protection method thereof. Background Art

[0002] In slope protection projects, traditional methods often rely on masonry, concrete pouring or installation of prefabricated parts to construct protective structures. However, these methods have exposed a series of technical problems and limitations in practical applications. First, the natural conditions of the slope are complex and changeable, and the soil strength, slope, moisture conditions and climatic conditions in different regions vary significantly. Traditional protective devices often use materials or structures of uniform strength, which makes it difficult to provide accurate and effective protection according to the specific conditions of the slope, resulting in insufficient protection in some areas and excess materials in other areas, resulting in waste of resources.

[0003] Secondly, traditional slope protection construction usually requires a lot of manpower and material resources, especially in complex terrain and hard-to-reach areas, which significantly increases the difficulty and cost of construction. This not only prolongs the construction period, but also increases the safety risks during the construction process.

[0004] Furthermore, most traditional protective devices are fixed structures that lack flexibility and adjustability. As slope morphology, soil conditions and climate factors change, these fixed structures may not be able to effectively respond to new protection needs, resulting in limited protection effects. At the same time, when repairs or replacements are needed, fixed structures are often difficult to quickly disassemble and reinstall, increasing maintenance costs and time.

[0005] In view of the above problems, there are some attempts to improve the existing technology, such as using stronger materials and designing more complex structures, but these methods often fail to fundamentally solve the limitations of traditional protective devices. Therefore, it is necessary to develop a new type of slope protection device and its protection method to overcome the shortcomings of the existing technology. Summary of the invention

[0006] To solve the above problems, the present invention provides a 3D printed gradient strength slope protection device and a protection method thereof, which utilizes the flexibility and precision of 3D printing technology to customize prefabricated panel modules of different strengths according to the natural conditions of different areas of the slope, and achieves stable connection and flexible adjustment between modules through quick disassembly and assembly of locking components.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a 3D printed gradient strength slope protection device, comprising a 3D printer, the 3D printer is used to print a 3D printed prefabricated plate according to the slope terrain to be protected, the 3D printed prefabricated plate is made of different materials, a groove is provided on the 3D printed prefabricated plate, a locking assembly is installed in the groove, the locking assembly comprises a shell, the shell is a hollow structure, the bottom and the top of the shell are provided with round holes, a rotating shaft is rotatably matched in the round hole, a locking tongue is fixedly connected to the rotating shaft, the locking tongue is a C-shaped structure, a monitoring assembly is installed on one side of the locking tongue, the monitoring assembly signal is connected to a control module, the monitoring assembly comprises a pressure sensor, the control module signal is connected to a reaction assembly, a wedge is fixedly connected to the end of the locking tongue away from the rotating shaft, and a limiting assembly is installed on the side of the shell away from the rotating shaft;

[0008] The limit assembly includes an insertion rod, the insertion rod passes through the shell and is slidably matched with the shell, the insertion rod is fixedly connected to a limit slot, the limit slot is located inside the shell, and the lock tongue is slidably matched with the inside of the limit slot;

[0009] When the pressure sensor detects that the pressure value of the lock tongue exceeds the threshold value in the control module, it means that the adjacent 3D printed prefabricated board has fallen off, and the control module starts the reaction component to make the lock tongue on the adjacent 3D printed prefabricated board unlocked.

[0010] The technical principle of the above scheme is as follows: the lock tongue is connected to the housing through a rotating shaft and can rotate freely in the circular hole. This design allows the lock tongue to rotate around the rotating shaft when subjected to external force, thereby changing its position state. The lock tongue is designed as a C-shaped structure, one end of which is fixedly connected to a wedge. When the lock tongue rotates to a specific angle, the wedge can naturally slide into the limit groove to achieve the locking function. The design of the C-shaped structure increases the contact area between the lock tongue and the limit groove, thereby improving the stability of the locking. When the lock tongue rotates to the locked position, the wedge is stuck in the limit groove, thereby preventing the lock tongue from rotating in the opposite direction and achieving a stable locking state. At the same time, the spring on the plug rod provides a certain pre-tightening force for the limit groove to ensure that the lock tongue is not easy to disengage from the limit groove when subjected to external force. Through the synergistic effect of components such as the lock tongue, the rotating shaft, the wedge, the plug rod and the limit groove, the quick connection and stable locking between the prefabricated panels are achieved. This design not only simplifies the installation process, but also improves the overall stability and durability of the protective device.

[0011] The above scheme has the following beneficial effects:

[0012] 1. This solution combines modular design with quick disassembly and locking components, making the construction process more efficient and convenient. Even in complex terrain and hard-to-reach areas, construction can be completed by quickly assembling and disassembling modules, greatly reducing the investment in manpower and material resources, and reducing construction difficulty and cost.

[0013] 2. In this solution, the design of the locking assembly makes the connection between the prefabricated panels more stable and reliable, effectively preventing the prefabricated panels from loosening or falling off due to external forces, and improving the overall safety of the slope protection device. The quick connection function of the locking assembly can greatly simplify the installation process of the prefabricated panels and improve construction efficiency. At the same time, the locking assembly is easy to operate and can be installed without complex tools and equipment.

[0014] 3. In this solution, due to the flexibility of 3D printing technology, the prefabricated panels can be customized according to the specific conditions of the slope, and the design of the locking components also has a certain degree of versatility, which can meet the connection requirements of prefabricated panels of different sizes and shapes. Therefore, the protective device has strong adaptability and flexibility. The device of the present invention allows flexible adjustment according to the specific form of the slope, soil conditions and possible changes in the future. When the slope conditions change or maintenance and replacement are required, the operator can quickly and safely separate and release individual modules while maintaining the orderliness and controllability of the entire system. This flexibility not only improves the adaptability of the protective device, but also reduces maintenance costs and time.

[0015] 4. In this solution, the C-shaped structure and limit component design of the locking assembly ensure the stability of the connection between modules, and maintain the overall stability of the protection system even in harsh environmental conditions. At the same time, the quick disassembly and assembly structure also has an automatic adjustment function, which can adjust the release and locking state of the structure according to the soil conditions of the covered area, further improving the safety performance of the protection device.

[0016] 5. This solution realizes real-time monitoring and intelligent response to the status of 3D printed prefabricated panels by integrating monitoring components and reaction components. When the pressure sensor detects that the pressure value of the lock tongue exceeds the preset safety threshold, it means that the adjacent 3D printed prefabricated panels may have fallen off or loosened. The control module starts the reaction component according to the received abnormal signal, and the reaction component can quickly respond to the command of the control module to change the lock tongue from a locked state to an unlocked state. This design not only reduces the risk of interference between adjacent prefabricated panels, but also avoids the chain reaction caused by the falling of a single prefabricated panel, thereby protecting the integrity and stability of the entire slope protection structure. At the same time, it also provides great convenience for subsequent maintenance and replacement work, because the staff can quickly locate the damaged prefabricated panel and repair or replace it without destroying the entire structure. Furthermore, a spring is sleeved on the plug rod, one end of the spring is fixedly connected to the top wall of the shell, and the other end of the spring is fixedly connected to the top of the limit groove.

[0017] Beneficial effects: The spring provides a continuous preload force for the limit slot, so that the wedge can be more stably constrained after being locked into the limit slot. This preload force helps prevent the lock tongue from being accidentally unlocked due to external vibration or impact, thereby improving the stability and reliability of the overall locking. The addition of the spring can also alleviate the direct impact and wear between the lock tongue and the limit slot to a certain extent, thereby extending the service life of the locking assembly. In addition, the elastic characteristics of the spring also help absorb part of the external impact energy and protect the entire protective device from damage.

[0018] Furthermore, a pull ring is fixedly connected to the top of the insertion rod, a limit rod is fixedly connected to the side wall of the insertion rod, and a groove matching the limit rod is opened on the top of the shell.

[0019] Beneficial effects: The design of the pull ring enables the user to grasp the insertion rod and operate it more conveniently. Whether it is insertion during installation or extraction during unlocking, it can be achieved by simply pulling the pull ring. This design reduces the direct contact area between the hand and the insertion rod, and improves the comfort and convenience of operation. The matching design of the limit rod and the groove on the top of the shell ensures that the insertion rod can remain stable after being inserted into the shell and is not easily removed by external force. This design increases the connection strength between the insertion rod and the shell, and improves the overall stability of the locking assembly. When it is necessary to unlock or disassemble the prefabricated panel, the user can easily pull out the insertion rod by pulling the pull ring to release the locked state. This design avoids the safety risks that may be caused by using tools or applying excessive force to unlock the operation, and improves safety during the construction process.

[0020] Furthermore, it also includes a water diversion pipe. A plurality of water diversion grooves are opened at the bottom of the 3D printed prefabricated plate. The water diversion grooves are connected to the water diversion pipe. A through groove is provided on the side wall of the water diversion pipe. The 3D printed prefabricated plate is slidably matched with the through groove.

[0021] Beneficial effects: Several water diversion channels opened at the bottom of the 3D printed prefabricated panels can effectively collect and guide the accumulated water or rainwater on the slope. These water diversion channels are connected to the water diversion pipes to form an efficient drainage system. When the water accumulated on the slope enters the water diversion channel, it will flow into the water diversion pipe along the water diversion channel and then be discharged from the slope area, effectively preventing the erosion and damage of the slope by water. By timely removing the accumulated water on the slope, the design of the water diversion pipe and water diversion channel helps to reduce the moisture content in the slope soil, reduce the weight and cohesion of the soil, and thus reduce the risk of slope landslides. This is of great significance to improving the overall stability and safety of the slope.

[0022] Furthermore, a through hole is provided at the bottom of the 3D printed prefabricated plate, an anchor rod is threadedly connected in the through hole, the anchor rod is a conical structure, a fixing component is installed in the through hole, the fixing component includes a connecting rod, the connecting rod passes through the 3D printed prefabricated plate and slides with the inside of the 3D printed prefabricated plate, one end of the connecting rod passes through the side wall of the through hole, and the side walls on both sides of the 3D printed prefabricated plate are provided with sockets matching the connecting rod.

[0023] Beneficial effects: When the cone-shaped anchor rod is screwed into the through hole, its cone design gradually increases the contact area between the anchor rod and the prefabricated panel, thereby enhancing the anchoring force. This design helps to ensure the stability of the prefabricated panel on the slope and prevent it from loosening or falling off due to external forces. The anchor rod and the through hole are connected by threads, making the installation process simpler and faster. At the same time, if the position or depth of the anchor rod needs to be adjusted, it can also be easily achieved by rotating the anchor rod, which improves construction efficiency.

[0024] After the anchor rod is screwed into the through hole and fixed, the connecting rod can further connect the prefabricated panel to the slope soil or other fixed structure through the socket. This double fixing method helps prevent the prefabricated panel from displacement or tilting when subjected to external forces. The use of anchor rods and fixing components enables the 3D printed prefabricated panel to be firmly fixed on the slope, improving the overall stability of the entire protective device. This helps prevent safety accidents such as slope landslides and ensures the safety of personnel and property.

[0025] Furthermore, a plurality of planting holes are provided on the top wall of the 3D printed prefabricated panel.

[0026] Beneficial effects: The planting holes provide space for vegetation planting, so that the prefabricated panels can not only serve as slope protection structures, but also support the growth of green plants. This helps the ecological restoration of the slope area, increases vegetation coverage, and improves the ecological environment. The roots of plants planted in the planting holes can penetrate deep into the soil and form a tight bond with the soil, thereby enhancing the soil's anti-scouring ability and anti-slip stability. This plays an important role in preventing slope landslides and maintaining slope stability. Vegetation coverage can reduce the direct scouring of the slope by rainwater and reduce the risk of soil erosion. At the same time, the growth of plants can also promote the formation of soil aggregate structure and improve the soil's ability to retain water and fertilizer.

[0027] A protection method for a 3D printed gradient strength slope protection device, applicable to the method for 3D printed gradient strength slope protection device, the specific steps are as follows:

[0028] Step 1: Survey the slopes that need to be protected, including but not limited to measuring the slope, soil strength and moisture content;

[0029] Step 2: Design a protection plan based on the survey results of step 1 and the specific conditions of the slope;

[0030] Step 3: According to the protection plan, select different 3D printing materials and processes to produce 3D printed prefabricated panels;

[0031] Step 4: Install 3D printed prefabricated panels made of different materials at different locations according to the protection plan, and use anchor rods to fix the 3D printed prefabricated panels to the slope surface. Adjacent 3D printed prefabricated panels are connected and fixed by locking components.

[0032] Step 5: Place the water pipes on both sides of the installed 3D printed prefabricated panels;

[0033] Step 6: Plant vegetation in the planting holes of the 3D printed prefabricated panels, and water, fertilize and prune the vegetation regularly.

[0034] Beneficial effects: The gradient strength prefabricated panels manufactured by 3D printing technology can adjust their strength according to the stress conditions at different locations, effectively enhancing the overall stability of the slope. 3D printing technology can achieve rapid and customized production of prefabricated panels, reducing production and transportation costs while improving construction efficiency. The use of environmentally friendly materials and ecological restoration methods conforms to the concept of sustainable development and helps to build a green ecological slope.

[0035] The installation of water diversion pipes and the water-permeable but soil-impermeable characteristics of eco-bags can significantly reduce the hydrostatic pressure of the slope and improve drainage performance. The planting and maintenance of vegetation not only beautifies the slope environment, but also further enhances the stability of the slope through the soil-fixing effect of the vegetation roots.

[0036] Furthermore, the protection scheme in step 2 includes the size, quantity, layout of the 3D printed prefabricated panels, and the installation positions of the locking components and the fixing components.

[0037] Beneficial effects: Through precise size, quantity and layout design, as well as the reasonable installation of locking components and fixing components, the 3D printed prefabricated panels can fit closely to the slope surface, forming an effective protective layer and significantly improving the stability of the slope. The gradient strength layout design can better adapt to the stress distribution of the slope, making the protective device have higher strength and durability at key locations. Through precise size and quantity design, the waste of prefabricated panels and unnecessary material consumption are reduced.

[0038] Further, 3D material selection in step three: according to the areas with different slopes and soil strengths, use printing materials with different gradient strengths.

[0039] Beneficial effects: By selecting printing materials that match the slope and soil strength, it is possible to ensure that the protective device has sufficient strength and stability in different areas, thereby more effectively resisting natural erosion and geological disasters. Material selection based on the specific conditions of different regions enables customized design of protective devices, improving their pertinence and effectiveness. Using materials that match regional conditions can avoid waste caused by excessive or low material strength and reduce overall costs.

[0040] Further, in step six, the vegetation is selected: the corresponding vegetation type is selected according to the specific environmental conditions of the slope, including soil type, light intensity and water conditions.

[0041] Beneficial effects: Vegetation with developed root systems can penetrate deep into the soil through its root network, enhancing the binding force between soil particles, thereby effectively preventing the occurrence of geological disasters such as soil erosion and landslides. The branches, leaves and roots of vegetation can slow down the direct scouring of the slope by rainwater, reduce the erosion of water on the soil, and maintain the integrity of the slope. Ecologically adapted vegetation species can attract various organisms to inhabit and reproduce, such as birds and insects, thereby enriching the biodiversity of the slope and forming a stable ecosystem. Planting vegetation can increase the vegetation coverage of the slope, increase air humidity, reduce temperature, improve the local climate environment of the slope, and provide better living conditions for organisms.

[0053] The following is further described in detail through specific implementation methods:

[0054] Embodiment 1:

[0055] As attached Figure 1-Figure 6As shown: A 3D printed gradient strength slope protection device includes a 3D printer, which is used to print a 3D printed prefabricated plate 1 according to the slope terrain to be protected. The 3D printed prefabricated plate 1 is made of different materials. A through hole 9 is provided at the bottom of the 3D printed prefabricated plate 1. An anchor rod is threadedly connected in the through hole 9. The anchor rod is a conical structure. A fixing component is installed in the through hole 9. The fixing component includes a connecting rod 10. The connecting rod 10 passes through the 3D printed prefabricated plate 1 and slides with the inside of the 3D printed prefabricated plate 1. One end of the connecting rod 10 passes through the side wall of the through hole 9. Both side walls of the 3D printed prefabricated plate 1 are provided with jacks matching the connecting rod 10. A plurality of planting holes are provided on the top wall of the 3D printed prefabricated plate 1.

[0056] A groove 101 is provided on the 3D printing prefabricated plate 1, and a locking assembly is installed in the groove 101. The locking assembly includes a shell 2, which is a hollow structure. The bottom and top of the shell 2 are provided with round holes. A rotating shaft 3 is rotatably fitted in the round hole. A locking tongue 4 is fixedly connected to the rotating shaft 3. The locking tongue 4 is a C-shaped structure. A wedge block 5 is fixedly connected to the end of the locking tongue 4 away from the rotating shaft 3. A limiting assembly is installed on the side of the shell 2 away from the rotating shaft 3; the limiting assembly includes a plug rod 6, which passes through the shell 2 and slides with the shell 2. A limiting groove 7 is fixedly connected to the plug rod 6. In this embodiment, the limiting groove 7 is a U-shaped structure. The limiting groove 7 is located inside the shell 2, and the locking tongue 4 slides with the inside of the limiting groove 7. A spring is sleeved on the plug rod 6, one end of the spring is fixedly connected to the inner top wall of the shell 2, and the other end of the spring is fixedly connected to the top of the limiting groove 7.

[0057] A monitoring component is installed on one side of the lock tongue 4, and the monitoring component signal is connected to the control module. The monitoring component includes a pressure sensor, and the control module signal is connected to the reaction component. In this embodiment, the reaction component is an electromagnet. When the pressure sensor detects that the pressure value of the lock tongue 4 exceeds the threshold value in the control module, it means that the adjacent 3D printed prefabricated plate 1 has fallen off. The control module starts the reaction component to make the lock tongue 4 on the adjacent 3D printed prefabricated plate 1 unlocked.

[0058] A pull ring is fixedly connected to the top of the insertion rod 6, a limit rod is fixedly connected to the side wall of the insertion rod 6, and a groove 101 matching the limit rod is opened on the top of the shell 2.

[0059] It also includes a water diversion pipe. A plurality of water diversion grooves 8 are provided at the bottom of the 3D printed prefabricated plate 1. The water diversion grooves 8 are connected to the water diversion pipe. A through groove is provided on the side wall of the water diversion pipe. The 3D printed prefabricated plate 1 is slidably matched with the through groove.

[0060] The specific implementation process is as follows: The specific protection method of the 3D printed gradient strength slope protection device is as follows:

[0061] (1) Preliminary preparation:

[0062] Use measurement tools (such as total stations, soil strength testers, and moisture meters) to conduct detailed surveys of slopes that need protection, and record key data such as slope gradient, soil strength, and moisture content. Analyze the geological conditions, potential risks, and environmental factors of the slopes to provide a basis for the design of subsequent protection plans.

[0063] According to the survey results and the specific conditions of the slope, a detailed protection plan is designed. The plan should specify the size, quantity, layout of the 3D printed prefabricated panels 1, as well as the installation positions of the locking components and the fixing components. Considering the areas with different slopes and soil strengths, 3D printing materials with different gradient strengths are determined to ensure the stability and durability of the protective device. The specific material selection is as follows:

[0064] Low slope and low soil strength areas: You can choose 3D printing materials with moderate strength and low cost, such as PLA (polylactic acid) and other biodegradable materials, which can meet both protection needs and environmental protection requirements.

[0065] Medium slope and medium soil strength areas: Materials with higher strength and better durability, such as ABS (acrylonitrile-butadiene-styrene copolymer) or engineering plastics such as nylon, can be selected to ensure the stability and durability of the protective device.

[0066] Areas with high slopes and high soil strength: High-strength and high-toughness materials, such as carbon fiber reinforced composites or metal alloys, should be used to cope with more severe environmental conditions.

[0067] (2) Production of 3D printed prefabricated panels 1:

[0068] According to the protection plan, select suitable 3D printing materials, prepare corresponding printing equipment and auxiliary materials, and pre-treat the materials to ensure that they meet the printing requirements.

[0069] Use 3D printing equipment to print and produce prefabricated panels according to predetermined sizes and shapes. During the printing process, adjust the printing parameters according to the material characteristics and process requirements to ensure the quality and performance of the prefabricated panels. Make a unique identification for each 3D printed prefabricated panel 1, and record its production batch, material type, size and other information to facilitate on-site installation and subsequent maintenance.

[0070] (3) On-site installation:

[0071] Clean up the debris and loose soil on the slope surface to ensure that the installation surface is flat and free of obstacles. According to the protection plan, mark the installation position of the prefabricated panels and the drilling positions of the anchor rods on the slope. Place the 3D printed prefabricated panels 1 printed with different materials at different predetermined positions to ensure that they fit tightly with the slope surface. Use drilling equipment to drill holes at the marked positions to ensure that the hole depth and hole diameter meet the design requirements.

[0072] At the bottom of the slope, the conical anchor rod is screwed into the borehole through the through hole 9 at the bottom of the 3D printed prefabricated panel 1 for fixing. During the screwing process, the connecting rod 10 in the through hole 9 is pushed out by the conical anchor rod and inserted into the socket of the adjacent side wall of the 3D printed prefabricated panel 1. The deeper the anchor rod is inserted, the more parts of the connecting rod 10 are pushed out, so that the adjacent 3D printed prefabricated panels 1 are connected more firmly. In the process of screwing the anchor rod into the borehole, pay attention to controlling the screwing speed and force to avoid damaging the 3D printed prefabricated panel 1 or the anchor rod. At the same time, ensure that the anchor rod reaches the predetermined depth to ensure its fixing effect. The anchor rod is combined with the through hole 9 at the bottom of the 3D printed prefabricated panel 1 to provide a strong vertical fixing force, which effectively prevents the displacement of the 3D printed prefabricated panel 1 in the soil.

[0073] After the 3D printed prefabricated plate 1 at the bottom is fixed, the adjacent 3D printed prefabricated plates 1 are installed one by one through the locking assembly. First, align the locking assembly on one 3D printed prefabricated plate 1 with the reserved groove 101 and the locking assembly on the other 3D printed prefabricated plate 1. Gently push the two 3D printed prefabricated plates 1 so that the lock tongue 4 begins to contact and gradually enters a state of mutual cooperation. Continue to apply thrust, and the lock tongue 4 rotates around the rotating shaft 3 after being subjected to pressure. When the lock tongue 4 reaches the maximum rotation angle, the wedge block 5 naturally slides into the limit groove 7, and at the same time the spring is compressed, the insert rod 6 slides in the shell 2, and the limit groove 7 clamps the wedge block 5 to keep the lock tongue 4 in the locked position, ensuring that the lock tongue 4 is stably maintained in the locked position, completing the stable connection of the two 3D printed prefabricated plates 1.

[0074] Place the water pipes on both sides of the installed 3D printed prefabricated panel 1 as a whole, and ensure that the water diversion trough 8 is properly connected to the water diversion pipe. Adjust the position and height of the water diversion pipe to effectively collect and guide rainwater or groundwater. During the installation process, check the installation position and angle of the 3D printed prefabricated panel 1 at any time to ensure that it fits tightly with the slope surface without gaps or misalignment. If necessary, use adjustment tools to make fine adjustments. The combination of the water diversion trough 8 and the water diversion pipe forms an efficient drainage system that can promptly remove the accumulated water on the slope, reduce the scouring effect of rainwater on the slope, and is also conducive to the growth of vegetation.

[0075] According to the specific environmental conditions of the slope, select vegetation types that are adapted to the ecology and have a well-developed root system for planting. Dig a planting pit of appropriate size in the planting hole of the 3D printed prefabricated panel 1, place the vegetation seedlings in the pit and backfill the soil. Water and apply an appropriate amount of fertilizer to promote the growth and development of the vegetation. The planting hole design promotes the natural growth of vegetation, which not only beautifies the slope, but also enhances the stability of the soil through the root system of the vegetation and reduces soil erosion. The selection of vegetation takes into account the local ecological environment, helps maintain biodiversity and promotes ecological balance. Specific vegetation selection suggestions are as follows:

[0076] Soil type: Choose appropriate vegetation types according to the soil type of the slope. For example, in sandy soil, you can choose drought-resistant and barren-resistant vegetation such as camel thorn and sea buckthorn; in clay soil, you can choose waterlogging-resistant and highly adaptable vegetation such as willow and reed.

[0077] Light intensity: Choose the appropriate vegetation type according to the light intensity of the slope. Positive plants such as Pinus tabulaeformis and Pinus massoniana are suitable for growing under full sunlight, while negative plants such as Dieffenbachia glabra and orchids are suitable for growing under weak light.

[0078] Moisture conditions: Choose appropriate vegetation types according to the moisture conditions of the slope. In humid areas, choose moisture-loving vegetation such as water lilies and lotus; in arid areas, choose drought-resistant vegetation such as cacti and sea buckthorn.

[0079] (4) Post-maintenance and management

[0080] Regularly inspect the slope protection devices and check the condition of precast panels, anchors, locking components and water pipes. Timely identify and handle loose, damaged or failed components to ensure the overall stability and safety of the protection devices. Over time, the geological conditions of the slope may change, such as increased soil strength, gentle slope, etc., resulting in the original protection device being no longer applicable or over-protective, and needing to be removed and reinstalled. Or when carrying out other slope-related construction (such as road widening, building foundation construction, etc.), it may be necessary to temporarily or permanently remove the slope protection device to ensure the smooth progress of the construction.

[0081] During the protection process, if a 3D printed prefabricated panel 1 falls off due to changes in the slope terrain (such as loose soil, rain erosion, earthquakes and other natural factors), the fallen 3D printed prefabricated panel 1 will exert a downward pulling force or squeezing effect on the adjacent 3D printed prefabricated panel 1 due to its own weight and possible tilt angle. At this time, the locking tongue 4 on the adjacent 3D printed prefabricated panel 1, as a key component for connection and fixing, will feel this additional pressure or load.

[0082] The pressure sensor installed on one side of the lock tongue 4 can monitor and capture the pressure changes on the lock tongue 4 in real time. Once the pressure value exceeds the threshold value preset in the control module (this threshold value is reasonably set according to the maximum pressure borne by the lock tongue 4 under normal working conditions), the control module will immediately recognize that this is an abnormal situation, that is, there may be a risk of falling off or about to fall off between adjacent 3D printed prefabricated panels 1.

[0083] After receiving this abnormal signal, the control module will quickly start the electromagnet connected to the signal. After receiving the command from the control module, the electromagnet will be powered off to make the magnetic force disappear. At this time, the lock tongue 4 will no longer be bound by the electromagnet and can be freely unlocked and detached from the adjacent 3D printed prefabricated board 1. The unlocked lock tongue 4 will no longer tightly hold the adjacent 3D printed prefabricated board 1, which allows the detached prefabricated board to move or fall off relatively independently when necessary without causing a chain reaction and causing more prefabricated boards to fall off. When the 3D printed prefabricated board 1 needs to be replaced, if it is necessary to separate two adjacent 3D printed prefabricated boards 1, the locking state must be released first. Pull the pull ring on the pull rod through external force (such as tools or manual) to overcome the spring force and slide to a certain position, so that the limit groove 7 no longer restricts the rotation of the lock tongue 4. After losing the limit, the lock tongue 4 automatically rotates back to the initial position due to the external force (the pulling force generated when the two 3D printed prefabricated panels 1 are separated), the wedge block 5 disengages from the limit groove 7, and the two locking components separate, thereby realizing the separation of the 3D printed prefabricated panels 1.

[0084] According to the growth of vegetation, regular maintenance work such as watering, fertilizing and pruning should be carried out. Weeds, fallen leaves and other debris should be removed to keep the slopes clean and well ventilated and light-permeable. The growth of vegetation should be monitored, the protection effect should be evaluated, and adjustments and optimizations should be made as needed.

[0085] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
