Description

Technical Field

[0001] This invention relates to the field of landscape engineering technology, specifically a method for creating long-lasting, low-maintenance flower bed landscapes. Background Technology

[0002] Flowerbed landscaping is a widely used horticultural configuration, primarily used in urban public spaces, road junctions, and courtyard designs. At the engineering structural level, a flowerbed is typically an artificially constructed system with clearly defined boundaries. Its core components include structural boundaries such as retaining walls or edge materials to define the geometry and withstand lateral pressure, a composite planting substrate layer to provide the water, nutrients, and air needed for plant root growth, and an ornamental plant community. The creation of flowerbed landscaping is essentially a process of systematically integrating and configuring these three key elements: structure, substrate, and plants.

[0003] To meet the demands of modern society for sustainable development and efficient resource utilization in urban horticulture, the introduction of long-term, low-maintenance construction methods is objectively necessary. The core value of this approach lies in reducing the system's dependence on continuous external resources, thereby enhancing the economic and environmental friendliness of flowerbed landscapes throughout their lifecycle. Related technologies typically employ single-mechanism self-healing materials, such as microcapsule-based repair agents or independently isolated stress monitoring and structural reinforcement methods. This makes it difficult to achieve comprehensive, coordinated maintenance of flowerbed structures, from submicron-level microcracks to macroscopic stress concentration areas. Furthermore, the repair process and stress adjustment often require external energy or human intervention, thus limiting the timeliness of repairs and the energy self-sufficiency of preventative maintenance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for creating long-lasting, low-maintenance flower bed landscapes. This method solves the problem of the difficulty in achieving comprehensive and coordinated maintenance of flower bed structures, from submicron-level microcracks to macroscopic stress concentration areas. The repair process and stress adjustment often require external energy or human intervention, which limits the timeliness of repair and the energy self-sufficiency of preventive maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for creating a long-lasting, low-maintenance flower bed landscape, comprising the following steps: S1. First, prepare a self-healing biomimetic concrete composite material, and embed biomineralizing agent microcapsules, piezoelectric composite fibers and thermosensitive color-changing composite coating into the composite material. S2. The flower bed structure boundary is prefabricated or cast on-site using the composite material prepared in S1; S3. On the inner side of the boundary of the flower bed structure, a composite matrix layer composed of pH-responsive hydrogel, thermal-responsive hydrogel and urease-producing microbial carrier is disposed, and an electro-responsive microcapsule is pre-placed. S4. Plant perennial, stress-resistant plants on the composite substrate layer and cover the substrate surface with decorative covering. S5. After the covering is applied, determine whether the ambient temperature is higher than the critical temperature, and trigger the thermosensitive color-changing composite coating and the thermally responsive hydrogel to respond based on the determination result. S6. Determine whether the structural stress monitored by the piezoelectric composite fiber has reached the warning threshold. If the determination is successful, the microelectrochemical triggers the electroresponsive microcapsule to release a high-viscosity polymerant in a directional manner, thereby adjusting the local stress at the boundary of the flower bed structure.

[0006] As a further description of the above technical solution: the application of biomineralizing agent microcapsules in S2 includes the following steps: The critical width for healing of the biomineralizing agent microcapsules was set. Determine whether the width of the microcracks at the boundary of the flower bed structure is less than the critical width; Triggering the rupture of the biomineralizing agent microcapsules to release microbial spores and nutrient solution; The microbial spores are used to metabolize and generate calcium carbonate crystals, which are then used to fill and heal cracks.

[0007] By adopting the above technical solution, the flower bed structure boundary achieves a self-healing function. That is, when micro-damage and micro-cracks occur, it can automatically monitor, judge and activate the internal material repair mechanism, so that the flower bed structure boundary has a targeted and localized active repair capability, reducing the dependence on external maintenance and preventing micro-cracks from evolving into macro-cracks, thereby extending the service life of the flower bed structure.

[0008] As a further description of the above technical solution: the application of the thermochromic composite coating in S2 includes the following steps: Set a preset temperature threshold for the thermosensitive color-changing composite coating; Determine whether the surface temperature of the thermosensitive color-changing composite coating reaches the preset temperature threshold. Adjust the surface emissivity and reflectivity of the thermochromic composite coating based on the judgment result; The adjustment of surface emissivity and reflectivity is used to regulate the heat load of the microenvironment inside the flower bed.

[0009] By adopting the above technical solution, the thermosensitive color-changing composite coating integrated into the flower bed structural boundary achieves passive and adaptive regulation of the microenvironment temperature inside the flower bed, enabling the flower bed structural boundary to respond to changes in ambient temperature. By changing its own photothermal properties of emissivity and reflectivity, it controls the absorption and dissipation of heat, thereby stabilizing the temperature of the substrate inside the flower bed.

[0010] As a further description of the above technical solution: the application of pH-responsive hydrogel in S3 includes the following steps: The relationship between the swelling degree of the pH-responsive hydrogel and the pH value of the plant rhizosphere is established; The swelling degree of the pH-responsive hydrogel is adjusted according to the aforementioned correspondence to trigger the nutrient release of the long-acting slow-release fertilizer.

[0011] By adopting the above technical solution, pH-responsive hydrogels achieve a perceptual and precise response to the nutritional needs of vegetation, establishing a linkage between the nutrient release process and the actual pH changes in the rhizosphere of the vegetation. By adjusting the swelling degree of the hydrogel, slow-release fertilizer can be released on demand, supplying nutrients to the plants when and in the amount they need.

[0012] As a further description of the above technical solution: the application of the urease-producing microbial vector in S3 includes the following steps: The activity of the urease-producing microbial carrier is adjusted to decompose urea in plant metabolic waste. Calculate the yields of ammonia and carbonates produced during the decomposition process; The ammonia produced during the decomposition process is used as a secondary nutrient for the plant.

[0013] By adopting the above technical solution and using biotechnology, urea waste generated by vegetation metabolism can be treated on-site and transformed into ammonia nitrogen nutrients that can be reused by vegetation. At the same time, the release rate of nutrients can be controlled by regulating the activity of microorganisms.

[0014] As a further description of the above technical solution: the synergistic function of the urease-producing microbial vector in S3 includes the following steps: Regulate the carbonate produced by the decomposition of waste by the urease-producing microbial carrier; Water is transported to the boundary of the flower bed structure via soil water. The carbonate is used to assist the biomineralization healing process of the biomineralizing agent microcapsules.

[0015] By adopting the above technical solution, carbonates produced by microbial metabolism in the matrix are used as an auxiliary material for structural healing. They are transported to the microcrack area of ​​the structural boundary through the natural path of soil water, thereby improving the effectiveness of self-healing repair of the structural boundary.

[0016] As a further description of the above technical solution: the application of thermally responsive hydrogels in the S5 environment adaptive regulation includes the following steps: Determine whether the ambient temperature is higher than the critical temperature; If the judgment is true, then the thermally responsive hydrogel undergoes a volume phase transition; The volume phase transition is used to release the stored water.

[0017] By adopting the above technical solution, the hydrogel is used as an intelligent water storage and supply unit. When the ambient temperature reaches a critical point that may threaten vegetation or cause rapid evaporation of water, the phase change mechanism inside it is automatically triggered to release the pre-stored water.

[0018] As a further description of the above technical solution: the triggering of the electroresponsive microcapsule in step S6 includes the following steps: The piezoelectric composite fiber generates a charge signal when the monitored stress reaches the early warning threshold. The charge signal is used as a microelectrochemical trigger energy source for the electroresponsive microcapsule.

[0019] By adopting the above technical solution, the mechanical and electrical energy conversion capabilities of the structural boundary material itself are utilized to directly convert potential structural stress risks into energy that triggers the repair mechanism. This energy self-sufficiency eliminates the dependence on external power sources or complex control systems. Piezoelectric composite fibers realize the energy self-sufficiency linkage between stress monitoring and micro-adhesive chemical triggering, ensuring the reliability of the stress response mechanism and reducing dependence on external energy.

[0020] As a further description of the above technical solution: S6 also includes the following steps: The directed-release high-viscosity polymer is used to form a flexible buffer pad in the stress concentration area; The local stress in the stress concentration area is adjusted according to the mechanical properties of the flexible buffer pad.

[0021] By adopting the above technical solution, the high-viscosity polymerizing agent achieves directional flexible treatment of stress concentration areas and redistribution of local stress, thus delaying the development of structural damage and extending the service life of the structure.

[0022] As a further description of the above technical solution: the maintenance and management of the flower bed structure boundary includes the following steps: Receive the stress signal from the piezoelectric composite fiber; Determine whether the stress signal has reached the warning threshold; Based on the judgment result, an instruction is issued to trigger the release of the polymerizing agent from the electroresponsive microcapsule in a micro-electrochemical manner; Then adjust the local stress at the boundary of the flower bed structure.

[0023] By adopting the above technical solutions, an integrated automatic closed-loop management of stress monitoring, early warning, triggering and stress adjustment is achieved, which can identify and eliminate potential risks in areas of structural stress concentration in advance, avoid macroscopic damage caused by stress accumulation, and maintain structural stability and long-term low-maintenance characteristics.

[0024] This invention provides a method for creating long-lasting, low-maintenance flower bed landscapes. It has the following beneficial effects: 1. This invention achieves the effect of self-healing and preventive maintenance of the flower bed structure from micro-damage to stress concentration by embedding biomineralizing agent microcapsules in the structure and using piezoelectric composite fibers to monitor stress in real time and trigger the polymer to regulate stress.

[0025] 2. This invention introduces urease-producing microbial carriers to convert plant metabolic waste into secondary nutrients and utilizes pH-responsive hydrogels to achieve on-demand release of slow-release fertilizer at the rhizosphere pH value, thus achieving precise, continuous, and stable substrate nutrient supply and the internal circulation of ecological substances.

[0026] 3. This invention achieves the dual adaptive regulation of heat load and water resources in the flower bed's internal microenvironment by applying a thermosensitive color-changing composite coating to adjust photothermal properties and by applying a thermally responsive hydrogel to automatically release water at critical temperatures.

[0027] 4. This invention uses the charge generated by piezoelectric composite fibers as the triggering energy for electroresponsive microcapsules and the directional release of high-viscosity polymerizing agents to form a flexible buffer pad in the stress zone, achieving the effect of stress response mechanism without external energy dependence and active flexibility treatment of structural stress concentration areas. Attached Figure Description

[0028] Figure 1 This is a flowchart of the method of the present invention. Detailed Implementation

[0029] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example: Please see the appendix Figure 1 This invention provides a method for creating a long-lasting, low-maintenance flower bed landscape, comprising the following steps: S1. First, prepare a self-healing biomimetic concrete composite material, and embed biomineralizing agent microcapsules, piezoelectric composite fibers and thermosensitive color-changing composite coating into the composite material. S2, The boundary of the flower bed structure is prefabricated or cast in place using the composite material prepared by S1; The application of biomineralizing agent microcapsules in S2 includes the following steps: Determine the critical healing width of the biomineralizing agent microcapsules; Determine whether the width of the microcracks at the boundary of the flower bed structure is less than the critical width; Triggering the rupture of biomineralizing agent microcapsules to release microbial spores and nutrient solution; Microbial spores are used to metabolize and generate calcium carbonate crystals, which in turn are used to fill and heal cracks.

[0031] Specifically, by embedding biomineralizing agent microcapsules into the composite material of the flower bed structure boundary and setting the critical width of healing as the initiation condition for self-repair, the basis for self-diagnosis of structural damage is achieved, ensuring that the repair mechanism is activated only when microcracks, i.e., cracks with a width less than the critical width, occur. When microcracks appear at the boundary of the flower bed structure and the width meets the set conditions, the local stress generated by the crack expansion will directly act on the microcapsules, triggering the physical rupture of the microcapsules and achieving the targeted release of the repair material. After rupture, the microcapsules will release pre-encapsulated microbial spores and nutrient solution into the crack. In the water environment of the crack, the spores are activated and the microorganisms begin to use the nutrient solution for biomimetic mineralization metabolism. Microorganisms generate calcium carbonate crystals during metabolism. These crystals, as insoluble solid products, naturally deposit and fill the spaces of microcracks, achieving self-closure and structural restoration of the cracks. Thus, the initial damage is repaired through the calcium carbonate filling process. This enables the flower bed structure boundary to acquire a precise, passive self-healing ability based on damage size, preventing microcracks from evolving into macrocracks and extending the service life of the structural boundary.

[0032] The application of thermochromic composite coating in S2 includes the following steps: Set the preset temperature threshold for the thermochromic composite coating; Determine whether the surface temperature of the thermochromic composite coating has reached the preset temperature threshold. Adjust the surface emissivity and reflectivity of the thermochromic composite coating based on the judgment results; Among them, the adjustment of surface emissivity and reflectivity is used to regulate the heat load of the microenvironment inside the flower bed.

[0033] Specifically, a thermochromic composite coating is applied to the boundary of a flower bed structure and a preset temperature threshold is set for it, thereby enabling it to change its optical and thermal properties at different temperatures. The preset temperature threshold is the objective condition for the coating to initiate a thermal regulation response. The surface temperature of the coating is monitored by a monitoring device, and it is determined whether the temperature reaches or exceeds the preset temperature threshold. When the ambient heat load increases, causing the surface temperature of the coating to reach the threshold, the thermochromic material inside the coating is triggered. The result of the triggering is that the surface emissivity and reflectivity of the coating undergo specific and reversible physical or chemical structural changes, such as changes in molecular conformation or liquid crystal phase transitions. Finally, based on the judgment results, the coating adjusts its surface emissivity and reflectivity. The adjustment of emissivity directly affects the coating's ability to radiate heat to the environment, while the adjustment of reflectivity directly affects the coating's absorption of sunlight and ambient heat. Through this passive, temperature-driven adjustment of photothermal properties, the objective control of the heat load of the microenvironment entering the flower bed is achieved. Thus, during use, the boundary of the flower bed structure acquires an adaptive thermal control function in response to changes in ambient temperature, achieving the effect of maintaining the stable temperature of the substrate inside the flower bed within a specific range.

[0034] S3. On the inner side of the flower bed structure boundary, a composite matrix layer composed of pH-responsive hydrogel, thermal-responsive hydrogel and urease-producing microbial carrier is configured, and an electro-responsive microcapsule is pre-placed. The application of pH-responsive hydrogels in S3 includes the following steps: Establish the relationship between the swelling degree of pH-responsive hydrogels and the pH value of plant rhizosphere; The swelling degree of pH-responsive hydrogels is adjusted according to the corresponding relationship to trigger the nutrient release of long-acting slow-release fertilizers.

[0035] Specifically, a pH-responsive hydrogel was configured in the composite substrate layer of the flower bed, and the objective correspondence between the swelling degree of the hydrogel and the pH value of the plant rhizosphere was pre-set. The correspondence between the swelling degree and the pH value is the basis for the hydrogel to realize the rhizosphere environment perception and release nutrients on demand by encapsulating long-acting slow-release fertilizer inside the hydrogel. During the life activities of plants, the roots release metabolites into the rhizosphere environment, causing local changes in the pH of the surrounding matrix. The polymer network structure of pH-responsive hydrogels is sensitive to such pH changes. According to the set correspondence, the swelling degree of the hydrogel will be directly regulated. The regulation of swelling degree is the conversion step from pH signal to physical action. Finally, based on the adjustment of its swelling degree, the hydrogel applies physical pressure to the encapsulated long-acting slow-release fertilizer or alters its release channels. This physical action triggers the release of nutrients from the long-acting slow-release fertilizer, directly delivering nutrients to the rhizosphere region, achieving controlled and precise nutrient supply. Furthermore, the pH-responsive hydrogel achieves linkage with changes in the plant's rhizosphere pH, precisely matching the nutrient release process with the plant's actual needs.

[0036] The application of urease-producing microbial vectors in S3 includes the following steps: Regulate the activity of urease-producing microbial carriers to decompose urea in plant metabolic waste; Calculate the yield of ammonia and carbonate produced during the decomposition process; The ammonia produced during the decomposition process is used as a secondary nutrient for plants.

[0037] Specifically, a urease-producing microbial carrier is configured in the composite substrate layer of the flower bed. This carrier is loaded with microorganisms possessing urease activity, either internally or on its surface. The technical solution adjusts the activity of these microbial carriers, including by controlling temperature, humidity, or the concentration of specific substances, to specifically decompose urea in plant metabolic waste. The microbial carriers perform the decomposition of urea; under the action of urease, urea is hydrolyzed, producing ammonia and carbonates, including bicarbonates or carbonates. The system calculates and monitors the yield of ammonia and carbonates during this hydrolysis process. The calculated yield results are used to quantitatively assess the entire waste conversion process. The ammonia generated during decomposition is rapidly converted into ammonium ions in the substrate environment. These ammonium ions are directly absorbed and utilized by plant roots as a secondary nutrient source for the plants. This process realizes the on-site resource utilization of metabolic waste and the internal cycle of nitrogen. Ultimately, the urease-producing microbial carrier decomposes and transforms urea in plant metabolic waste, thus providing secondary nitrogen nutrition for plants and supporting the internal cycle of substrate ecological materials.

[0038] The synergistic function of S3 on urease-producing microbial vectors includes the following steps: Regulates the carbonate produced by urease-producing microbial carriers during waste decomposition; Water is transported to the boundary of the flower bed structure through the soil; Among them, carbonates are used to assist the biomineralization healing process of biomineralizing agent microcapsules.

[0039] Specifically, the urease-producing microbial carrier configured in the composite substrate layer of the flower bed decomposes metabolic wastes such as urea to produce carbonates, including bicarbonates and carbonates. The decomposition process controls the yield and concentration of carbonates produced. The carbonate products generated in the substrate are transported to the microcrack area at the boundary of the flower bed structure via natural hydraulic pathways such as infiltration and capillary action, using soil water as a transport medium. The carbonate transport process realizes the functional connection between the substrate layer and the structural boundary in terms of chemical substances. Finally, carbonates transported to the microcrack region serve as an auxiliary substance, participating in and supporting the biomineralization healing process of microbial spores released from the biomineralizing agent microcapsules. Carbonates provide the necessary reactants or environmental conditions to promote the metabolism of microbial spores to generate calcium carbonate crystals. This synergistic effect improves the generation efficiency and yield of calcium carbonate crystals in the crack healing material. Urease-producing microbial carriers realize the transformation and transport of metabolic waste products into structural self-healing auxiliary materials, thereby enhancing the biomineralization healing efficiency of structural boundaries. Secondly, the ratio and chemical properties of the pH-responsive hydrogel and the urease-producing microbial carrier are pre-adjusted so that their endogenous pH and nutrient supply characteristics can match the specific physiological needs of the different plant communities selected in S4; and electroresponsive microcapsules for structural maintenance are pre-placed in the composite matrix layer.

[0040] S4. Plant perennial, stress-resistant plants on the composite substrate layer and cover the substrate surface with decorative covering. S5. After the covering material is applied, determine whether the ambient temperature is higher than the critical temperature, and trigger the thermosensitive color-changing composite coating and the thermally responsive hydrogel to respond based on the determination result. The application of thermally responsive hydrogels in S5 environmental adaptive conditioning includes the following steps: Determine if the ambient temperature is higher than the critical temperature; If the judgment is valid, a volume phase transition is triggered in the thermally responsive hydrogel; The volume phase transition is used to release the stored water.

[0041] Specifically, a thermoresponsive hydrogel is incorporated into the composite matrix layer of the flower bed. This material stores water through its polymer network structure. Based on the objective relationship between the ambient temperature and the preset critical temperature, the system judges the physical condition threshold that the hydrogel must reach to undergo a volume phase transition. When the judgment is valid, that is, when the ambient temperature reaches or exceeds the critical temperature, the ambient heat energy is absorbed by the hydrogel, driving structural changes in its internal polymer chains. Through structural changes, the hydrogel undergoes a thermoinduced volume phase transition, that is, it rapidly changes from a highly swollen state to a low-swelling state, and its volume shrinks. During the phase transition and shrinkage process, the ability of the polymer network structure to bind water decreases sharply. The water previously stored and retained in the network pores is forcibly discharged and released into the surrounding composite matrix layer. This water release process realizes the adaptive and passive replenishment of moisture in the microenvironment inside the flower bed. Thermoresponsive hydrogel realizes the passive regulation of water release according to changes in ambient temperature, thus achieving the effect of stabilizing the moisture content of the composite matrix layer of the flower bed under high temperature conditions.

[0042] S6. Determine whether the structural stress monitored by the piezoelectric composite fiber has reached the warning threshold. If the determination is successful, the micro-electrochemical triggers the electroresponsive microcapsules to release high-viscosity polymerizing agent in a directional manner, thereby adjusting the local stress at the boundary of the flower bed structure.

[0043] The triggering of the electroresponsive microcapsule in S6 includes the following steps: The piezoelectric composite fiber generates a charge signal when the monitored stress reaches the early warning threshold. The charge signal is used as a microelectrochemical trigger energy source for the electroresponsive microcapsule.

[0044] Specifically, firstly, piezoelectric composite fibers are embedded in the composite material of the flower bed structure boundary. The piezoelectric effect converts mechanical energy into electrical energy and continuously monitors the stress level of the structure. When the stress reaches a preset warning threshold, the piezoelectric composite fibers deform, converting the mechanical stress into a charge signal with specific voltage and current parameters. The generation of this signal indicates that the structural damage risk has reached a critical state that requires the initiation of repair. The generated charge signal serves as a micro-electrochemical trigger energy source, which is directly delivered or acts on the electroresponsive microcapsules pre-placed in the composite matrix layer through electric field induction. The capsule wall structure is sensitive to electric field or microcurrent. The micro-electrochemical effects of the charge signal, including electrolysis, redox, or electric field-induced structural rearrangement, are used as energy sources to drive the failure of the microcapsule wall structure. Under the micro-electrochemical triggering effect of charge signals, the capsule walls of microcapsules undergo directional and localized rupture or enhanced permeability, resulting in the precise release of the internally encapsulated high-viscosity polymer to stress concentration and crack initiation areas. The high-viscosity polymer then reacts and solidifies with other components in the matrix, achieving rapid and localized repair of damage. This completes a self-sufficient closed loop of structural stress monitoring, electrical energy conversion, and repair agent release, and achieves controlled release of the high-viscosity polymer. By utilizing the mechanical-to-electrical energy conversion capability of piezoelectric composite fibers, the micro-electrochemical triggering of the repair mechanism by stress signals is realized, achieving the functions of eliminating dependence on external power sources, ensuring the reliability of stress response mechanisms, and realizing precise and rapid solidification and repair of high-viscosity repair agents.

[0045] S6 also includes the following steps: Directionally released high-viscosity polymers are used to form flexible buffer pads in areas of stress concentration; The local stress in the stress concentration area is adjusted based on the mechanical properties of the flexible buffer pad.

[0046] Specifically, after the electroresponsive microcapsules are triggered, the high-viscosity polymer inside is directionally released to the stress concentration area at the boundary of the flower bed structure. After release, the polymer reacts with the surrounding matrix components to form a flexible buffer pad with specific mechanical properties, including elastic modulus and Poisson's ratio. As a new structural element, the flexible buffer pad has objectively different mechanical properties from the rigid properties of the surrounding composite materials. When external loads or internal stresses are applied to the area again, the deformation capacity of the buffer pad will absorb and disperse some of the energy, objectively regulating the local stress distribution in the stress concentration area. The mechanical properties of the flexible buffer pad determine its stress dispersion ability and efficiency. Based on the mechanical properties of the flexible buffer pad, including its elasticity, viscosity, and strength parameters, the local stress in the stress concentration area is objectively adjusted. This adjustment disperses the original stress peak and transforms the concentrated stress into dispersed stress, thereby reducing the physical risk of microcrack re-initiation and propagation. The flexible buffer pad formed by the directional release of high-viscosity polymerizing agent achieves passive adjustment of the local stress distribution of the structure, thereby reducing the probability of structural damage and improving the structural boundary toughness.

[0047] The maintenance and management of the flower bed structure boundary includes the following steps: Receives stress signals from piezoelectric composite fibers; Determine whether the stress signal has reached the warning threshold; Based on the judgment result, an instruction is issued to trigger the release of polymerizing agent from electroresponsive microcapsules in a micro-electrochemical manner; Then adjust the local stress at the boundary of the flower bed structure.

[0048] Specifically, the maintenance and management process uses piezoelectric composite fibers embedded in the composite material of the flower bed structure boundary to achieve real-time monitoring of the structural stress level. The piezoelectric composite fibers convert the externally applied mechanical stress into an electric charge signal with specific parameters. The device receives this electric charge signal and objectively judges its amplitude against a preset warning threshold. This judgment step determines whether the structural damage risk has reached the critical state that requires repair intervention. If the judgment result is valid, that is, the stress signal reaches the warning threshold, an instruction will be issued to use the electric charge signal as a micro-electrochemical trigger energy to act on the pre-placed electroresponsive microcapsules. This trigger energy induces directional and localized structural failures in the microcapsule wall, such as rupture or increased permeability, resulting in the precise and directional release of the internally encapsulated high-viscosity polymer to the stress concentration area. The directed release of high-viscosity polymerizing agent undergoes a curing reaction with the surrounding matrix in the stress concentration area, forming a flexible buffer pad with a specific elastic modulus and viscosity coefficient. Through the inherent deformation capacity and mechanical property differences of this buffer pad, the local stress acting on the area is adjusted. By absorbing stress energy and dispersing stress peaks, the risk of structural damage is dynamically intervened. The flower bed structure boundary acquires an energy-self-sufficient closed-loop maintenance capability, achieving the effect of transforming structural stress concentration into locally dispersed stress and effectively reducing the risk of secondary damage.
