Description

Technical Field

[0001] This invention relates to the field of ecological revetment, specifically to a passive capillary microsiphon adaptive sensing low-maintenance ecological revetment structure. Background Technology

[0002] In recent years, with the increasing number of landscaping projects, ecological revetment construction has been carried out in various places. The scale of landscaping and waterfront ecological revetment projects continues to expand. As the core carrier connecting the aquatic and terrestrial ecosystems, regulating runoff and carrying landscape vegetation, the structural reliability, ecological adaptability and long-term operation and maintenance efficiency of ecological revetments directly determine the comprehensive ecological benefits of waterfront spaces.

[0003] Existing ecological revetments, often constructed using conventional methods such as concrete ecological frames and fir pile revetments, are ill-suited to the cyclical fluctuations in river water levels. They fail to match the dynamic changes in water levels with the water requirements of seedlings, resulting in seedlings being subjected to alternating drought and flood stress environments, leading to low overall survival rates and significant challenges in subsequent maintenance and management. Regarding water regulation and maintenance costs, traditional revetments commonly suffer from uneven water supply to plants: during the dry season, soil moisture content on the slope decreases, making slope vegetation prone to dehydration and wilting, requiring extensive manual irrigation or electric pumping systems, resulting in high labor and energy costs; during the wet season or after heavy rainfall, water accumulation within the revetment cannot be drained promptly, easily causing root rot due to oxygen deficiency, severely impacting normal plant growth and the long-term maintenance of the revetment's ecological benefits.

[0004] Therefore, it is essential to provide a passive capillary micro-siphon adaptive sensing low-maintenance ecological revetment structure to solve the above-mentioned technical problems. Summary of the Invention

[0005] Based on the above description, the present invention provides a passive capillary micro-siphon adaptive sensing low-maintenance ecological revetment structure to solve the problem of uneven plant water supply and high labor and energy costs in existing revetments.

[0006] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A passive capillary micro-siphon adaptive sensing low-maintenance ecological revetment structure includes a concrete outer wall structure and planting areas and a water storage chamber distributed from top to bottom. A siphon drainage pipe communicating with the water storage chamber is installed on the concrete outer wall structure. A capillary water-conducting fiber is connected to the siphon drainage pipe. The capillary water-conducting fiber extends from the water storage chamber to the planting area. A water level and temperature integrated sensing probe is connected in the planting area and the water storage chamber. The water level and temperature integrated sensing probe is configured to: monitor the water temperature and water level inside the concrete outer wall structure, and control the siphon drainage pipe to discharge excess water when the water level exceeds a preset value.

[0007] Furthermore, a ferromagnetically controlled flexible folding check valve is installed at the inlet of the siphon drainage pipe, and a Hall sensor, a miniature magnetic core, and a control circuit are integrated inside the integrated water level and temperature sensing probe. The control circuit inside the integrated water level and temperature sensing probe is electrically connected to the electromagnetic drive component inside the siphon drainage pipe.

[0008] Preferably, the system includes an integrated water level and temperature sensing probe (with an internal Hall sensor and micro magnetic core), a lightweight porous composite material crossbar for water filtration, a concrete outer wall structure, tenon and mortise connectors, a water storage chamber (with built-in sulfur / iron bimetallic modified biochar ceramic particles), capillary water-conducting fibers, a siphon drainage pipe, a ferromagnetically controlled flexible folding check valve, planting soil, and water-tolerant plants. This ecological approach to the revetment achieves the effects of "self-breathing, self-watering, and self-draining," allowing for healthy and sustainable plant growth within the rectangular blocks of the ecological revetment. The modular assembly method makes construction more convenient. The flood-resistant siphon drainage pipe features an externally mounted magnetically controlled flexible folding check valve. A Hall sensor and a miniature magnetic core are integrated inside the water level and temperature probe. When the probe detects that the river level exceeds the warning line during flood season (or abnormal water turbidity), the probe's control circuit is instantly energized to generate a magnetic field, driving the ferromagnetic flexible valve at the siphon opening to forcefully close. The flood-resistant siphon drainage pipe needs to be connected to capillary water-conducting fibers to drive the ferromagnetic flexible valve at the siphon opening, ensuring the passage of water for both drainage and entry. The integrated water level and temperature sensing probe (containing a ferromagnetic flexible valve) serves to detect water level and temperature. A Hall sensor and a miniature magnetic core are integrated within the probe. When the probe detects that the river level exceeds the warning line during flood season (or abnormal water turbidity), the probe's control circuit is instantly energized to generate a magnetic field, driving the ferromagnetic flexible valve at the siphon inlet to forcefully close. It can sense the impact of water level, thus providing a direct understanding of plant growth. When rainwater enters the soil, excess rainwater is filtered through a lightweight porous composite material plate, allowing some water to remain in the storage chamber (containing sulfur / iron bimetallic modified biochar ceramic particles). This provides moisture to plant roots. The large specific surface area of ​​these ceramic particles not only provides excellent water storage and buffering capacity, but the Fe / Mn oxides loaded on their surface, when interacting with capillary water-conducting fibers during micro-circulation, catalyze the generation of reactive oxygen species (ROS), triggering a Fenton-like reaction that efficiently degrades antibiotic and pesticide residues in runoff. The capillary water-conducting fibers connect with the soil through gaps, and then connect to the siphon tubes. Excess water is drained through the siphon drainage pipes. Additionally, when there is too much water in the storage chamber, excess water is drained through the flood-prevention siphon drainage pipe (magnetically controlled flexible folding check valve) to prevent waterlogging of the plants. The system can self-regulate through the water level in the storage chamber to ensure that the water level meets the conditions for plant growth.

[0009] Furthermore, a lightweight porous composite material plate for water filtration is provided between the planting area and the water storage chamber. The lightweight porous composite material plate for water filtration is made of polymer composite material and has multiple holes evenly distributed on it.

[0010] Preferably, the diameter of the hole is 3 mm.

[0011] Furthermore, the integrated water level and temperature sensing probe is made of stainless steel, and its outer surface is engraved with scale lines.

[0012] Preferably, the water level and temperature integrated sensing probe has an internal Hall sensor and a micro magnetic core, and is engraved with scale lines on the outside. It is made of 304 stainless steel.

[0013] Furthermore, the planting area is provided with planting soil for planting plants, the upper surface of the planting soil is 5cm lower than the top surface of the concrete outer wall structure, and a 5cm thick layer of lightweight expanded clay is laid below the planting soil.

[0014] Preferably, the planting soil is 5cm below the top surface of the concrete module, and 5cm of lightweight expanded clay pebbles are placed below the planting soil. Water-tolerant plants (such as iris and yellow iris) are planted on top of the planting soil.

[0015] Furthermore, the water storage chamber is filled with sulfur / iron bimetallic modified biochar ceramic particles.

[0016] Furthermore, the sulfur / iron bimetallic modified biochar ceramic particles are loaded with Fe / Mn oxides on their surface, which are used to catalyze a Fenton-like reaction during water microcirculation with the capillary water-conducting fibers, thereby degrading pollutants in the water.

[0017] Furthermore, the water storage chamber has a reserved water storage space, which is located above the sulfur / iron bimetallic modified biochar ceramic particles.

[0018] Furthermore, the concrete outer wall structure is prefabricated from lightweight expansive concrete.

[0019] Furthermore, the concrete outer wall structure is connected with tenon and mortise connectors, and adjacent concrete outer wall structures are connected through the tenon and mortise connectors.

[0020] Preferably, the concrete module is made of lightweight expansive concrete, which can achieve rapid assembly and fixation through the interlocking relationship of mortise and tenon connectors.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. By coupling capillary water-conducting fibers with siphon drainage pipes and integrating them with a water level and temperature sensing probe for water level linkage control, the system can adaptively regulate the internal moisture state of the revetment according to changes in river water level, rainfall, and evaporation conditions. During the dry season, the capillary action of the capillary fibers continuously delivers water from the storage chamber to the planting area, replenishing the water needed for slope plants and preventing them from drying out due to lack of water. During the wet season or after heavy rainfall, when the water level in the storage chamber exceeds a preset threshold, the siphon drainage pipe is automatically triggered to drain the accumulated water, preventing plant roots from rotting due to long-term waterlogging and lack of oxygen. This mechanism fundamentally solves the problem of uneven distribution of water in traditional revetment plants, adapts to dynamic water level changes, provides a stable growing water environment for seedlings, and significantly improves plant survival rate and the long-term effectiveness of the landscape effect. 2. A passive, low-energy control solution is adopted, combining a "ferromagnetically controlled flexible folding check valve and an integrated water level and temperature sensing probe." The core water circulation process relies on purely physical capillary and siphon effects, with zero power consumption throughout normal water replenishment and drainage, eliminating the need for electric pumping equipment. This structure is naturally suited to the complex conditions of high humidity and high sediment in waterfront areas. It avoids the high-frequency failures of traditional valves, such as clogging by sediment or short circuits in electrical equipment due to water immersion. It is unaffected by power outages and conventional mechanical failures. From the block structure source, it avoids the "pseudo-low maintenance" drawbacks of traditional "smart irrigation" systems in waterfront environments, which involve frequent repairs and high maintenance costs, achieving truly long-term stable operation with low maintenance costs.

[0024] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0025] like Figures 1 to 3 As shown, a passive capillary microsiphon adaptive sensing low-maintenance ecological revetment structure includes a concrete outer wall structure 1 and planting areas 2 and water storage chambers 3 distributed from top to bottom. A siphon drainage pipe 4 communicating with the water storage chamber 3 is installed on the concrete outer wall structure 1. Capillary water-conducting fibers 5 are connected to the siphon drainage pipe 4 and extend from the water storage chamber 3 to the planting area 2. Water level and temperature integrated sensing probes 6 are connected in the planting area 2 and the water storage chamber 3. The water level and temperature integrated sensing probes 6 are configured to monitor the water temperature and water level inside the concrete outer wall structure 1, and control the siphon drainage pipe 4 to discharge excess water when the water level exceeds a preset value.

[0026] In this embodiment, by setting up planting areas 2 and water storage chambers 3 arranged vertically inside the concrete outer wall structure 1, a layered integrated structure of "planting and bearing above, water storage and regulation below" is formed. This provides a stable planting and growth space for plants and has the ability to retain rainwater and buffer hydrology. It breaks through the limitations of traditional prefabricated ecological frames that are just simple cavities and lack water circulation functions. It realizes the functions of planting plants, runoff regulation and hydrological control simultaneously within a single block unit, preserves the hydrological exchange channel between land and water, and avoids the defect of hard revetments that isolate the ecological connection between land and water.

[0027] Furthermore, relying on the structural design of the capillary water-conducting fiber 5 connecting the water storage chamber 3 and the planting area 2, the water in the water storage chamber 3 can be continuously and passively transported to the upper planting area 2 using purely physical capillary action, providing a stable supply of water for plant roots. During the dry season, there is no need to rely on electric pumping equipment or manual irrigation operations to maintain the water requirements for plant growth, fundamentally solving the pain points of traditional revetments where slope plants are prone to drying out during the dry season, and the high cost of manual maintenance and pumping. The entire process consumes zero power, and the water replenishment process is stable and without mechanical wear. In the above embodiments, the integrated water level and temperature sensing probe 6 possesses status monitoring and critical alarm capabilities. Under normal circumstances, it operates in a low-power, silent state. Only when key indicators such as capillary depletion or drainage blockage reach the failure threshold is an alarm automatically triggered, prompting manual intervention. This drives a shift in revetment maintenance from the traditional "blind inspection and laissez-faire maintenance" to "targeted intervention and precise maintenance." This mechanism significantly reduces the frequency of daily inspections, resulting in a substantial decrease in overall maintenance costs compared to the traditional daily inspection model. Simultaneously, it effectively avoids large-scale landscape damage caused by untimely maintenance and delayed fault detection, ensuring the long-term stability of the revetment's ecological landscape.

[0028] In some embodiments, a ferromagnetically controlled flexible folding check valve is provided at the inlet of the siphon drain pipe 4, and a Hall sensor, a miniature magnetic core and a control circuit are integrated inside the water level and temperature integrated sensing probe 6. The control circuit inside the water level and temperature integrated sensing probe 6 is electrically connected to the electromagnetic drive component inside the siphon drain pipe 4.

[0029] In this embodiment, a non-contact magnetic drive scheme using Hall sensors, miniature magnetic cores, and electromagnetic drive components is adopted to replace the rigid mechanical valve core transmission structure of traditional solenoid valves. The drive process has no rigid friction or jamming points, which can effectively avoid the clogging and jamming problems of silt and debris in the waterfront body on the valve opening and closing mechanism. The entire drive control component is integrated and encapsulated inside the probe and drainage pipe, with no exposed moving parts. It can resist the corrosion of circuits and mechanical structures by high humidity and water immersion environment, significantly reduce the probability of equipment failure, extend the service life of the revetment drainage system, and meet the low maintenance design goal.

[0030] In some embodiments, a water-filtering lightweight porous composite material horizontal plate 11 is provided between the planting area 2 and the water storage chamber 3. The water-filtering lightweight porous composite material horizontal plate 11 is made of polymer composite material and has a plurality of holes 111 evenly distributed on it.

[0031] In this embodiment, the evenly distributed holes 111 can provide a smooth drainage channel for the infiltrated water in the planting area 2, and can also effectively intercept planting substrate particles such as planting soil and lightweight expanded clay granules, preventing the substrate from being washed away by the water flow during rainfall, which would lead to a thinning of the planting layer and a decrease in fertility. At the same time, it can filter suspended solids and silt carried by runoff, reduce the entry of impurities into the lower water storage chamber, prevent the pores of the sulfur / iron bimetallic modified biochar expanded clay granules 31 from being blocked, and prevent the siphon drainage pipe 4 and capillary water-conducting fiber 5 from being silted up and failing. This reduces the risk of system blockage from the structural source, reduces daily cleaning and maintenance operations, and extends the service life of core functional components.

[0032] In some embodiments, the integrated water level and temperature sensing probe 6 is made of 304 stainless steel and has scale lines engraved on its outer surface.

[0033] In this embodiment, the properties of 304 stainless steel enable the integrated water level and temperature sensing probe 6 to possess excellent resistance to water corrosion, silt abrasion, and freeze-thaw cycles. It can be submerged in the revetment water and high-humidity environments for extended periods without easily rusting, aging, or structural damage, effectively resisting long-term erosion by pollutants and silt in the water. During the construction and assembly phase, the scale lines can serve as a depth positioning reference, facilitating precise control of the probe's insertion depth into the planting area and water storage chamber. This ensures uniformity in the installation reference of the probes within each modular block, guaranteeing consistency in water level monitoring thresholds and improving the standardization accuracy of the project construction. During routine operation and maintenance, the electronic monitoring data can be periodically calibrated using intuitive readings of the scale lines, promptly correcting drift deviations caused by long-term sensor operation, ensuring the accuracy of water level monitoring data, providing a reliable basis for the precise opening and closing control of the siphon drainage pipe, and further enhancing the control accuracy of the revetment hydrological adaptive sensing.

[0034] In some embodiments, the planting area 2 is provided with planting soil 21 for planting plants, the upper surface of the planting soil 21 is 5cm lower than the top surface of the concrete outer wall structure 1, and a 5cm thick layer of lightweight expanded clay aggregate 211 is laid below the planting soil 21.

[0035] In this embodiment, a 5cm thick layer of lightweight expanded clay granules 211 is laid under the planting soil to form a breathable and water-retaining buffer transition layer: during the wet season, the pores of the expanded clay granules layer can quickly drain the infiltrated water, avoid long-term saturation and water accumulation in the planting soil, ensure the aeration of plant roots, and effectively prevent root hypoxia and rot; during the dry season, the expanded clay granules layer can retain water and moisture by relying on its own pores, and evenly spread the water transported by the capillary water-conducting fibers to the bottom of the entire planting area, continuously replenishing water for plant roots and alleviating drought stress during the dry season.

[0036] In some embodiments, the water storage chamber 3 is filled with sulfur / iron bimetallic modified biochar ceramic particles 31.

[0037] In some embodiments, the surface of the sulfur / iron bimetallic modified biochar ceramic particles 31 is loaded with Fe / Mn oxides, which are used to catalyze a Fenton-like reaction when the capillary water-conducting fibers 5 undergo water flow microcirculation, thereby degrading pollutants in the water.

[0038] In this embodiment, sulfur / iron bimetallic modified biochar ceramic particles 31 are filled into the water storage chamber 3. The Fe / Mn oxides loaded on their surface can catalyze a Fenton-like reaction during the micro-circulation of water driven by capillary water-conducting fibers 5, degrading organic pollutants and nutrients such as nitrogen and phosphorus carried by runoff in situ. This achieves deep purification of non-point source pollution while storing and regulating water. Compared with the shortcomings of traditional hard revetments that isolate the ecological connection between water and land, this structure retains the hydrological exchange and material cycle channel between water and land. The revetment morphology is more ecologically natural and can simultaneously perform the combined functions of hydrological regulation, water purification, and ecological habitat, demonstrating outstanding ecological and environmental benefits in practical engineering applications.

[0039] In some embodiments, a water storage space 32 is reserved in the water storage chamber 3, and the water storage space 32 is located above the sulfur / iron bimetallic modified biochar ceramic particles 31.

[0040] In this embodiment, the water storage space 32 can form a continuous free water layer, ensuring that the lower water intake end of the capillary water-conducting fiber 5 is always immersed in the free water body. This avoids insufficient water volume at the water intake end and interruption of capillary water conduction due to the adsorption and water retention effect of the sulfur / iron bimetallic modified biochar ceramic particles 31. During the dry season, the water in the water storage chamber can still be continuously and stably transported to the upper planting area, providing uninterrupted passive water replenishment for the plants, further strengthening the water guarantee for plant growth during the dry season, and reducing the need for artificial water replenishment.

[0041] In some embodiments, the concrete outer wall structure 1 is precast from lightweight expansive concrete.

[0042] In this embodiment, the concrete outer wall structure 1 is made of lightweight expansive concrete prefabricated, which has high structural strength, excellent resistance to damage and freeze-thaw, and solves the problems of traditional revetment not being firmly fixed and components being easily damaged and aged.

[0043] In some embodiments, the concrete outer wall structure 1 is connected to a tenon and mortise connector 7, and adjacent concrete outer wall structures 1 are connected by the tenon and mortise connector 7.

[0044] In this embodiment, all core functional components, including capillary drainage, siphon drainage, water level and temperature sensing, and water purification, are integrated into standardized prefabricated lightweight expansive concrete blocks, forming a fully functional independent unit. On-site, the blocks are simply joined together using tenon and mortise connectors to form the revetment. This simple and efficient assembly process significantly improves the construction efficiency and standardization of landscape revetment projects. The modular unit is highly reproducible, flexibly adaptable to waterfront shorelines of different lengths and shapes. Furthermore, damaged blocks can be independently disassembled and replaced without the need for complete revetment demolition, significantly enhancing the convenience of future maintenance.

[0045] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. By coupling capillary water-conducting fibers with siphon drainage pipes and integrating them with a water level and temperature sensing probe for water level linkage control, the system can adaptively regulate the internal moisture state of the revetment according to changes in river water level, rainfall, and evaporation conditions. During the dry season, the capillary action of the capillary fibers continuously delivers water from the storage chamber to the planting area, replenishing the water needed for slope plants and preventing them from drying out due to lack of water. During the wet season or after heavy rainfall, when the water level in the storage chamber exceeds a preset threshold, the siphon drainage pipe is automatically triggered to drain the accumulated water, preventing plant roots from rotting due to long-term waterlogging and lack of oxygen. This mechanism fundamentally solves the problem of uneven distribution of water in traditional revetment plants, adapts to dynamic water level changes, provides a stable growing water environment for seedlings, and significantly improves plant survival rate and the long-term effectiveness of the landscape effect. 2. A passive, low-energy control solution is adopted, combining a "ferromagnetically controlled flexible folding check valve and an integrated water level and temperature sensing probe." The core water circulation process relies on purely physical capillary and siphon effects, with zero power consumption throughout normal water replenishment and drainage, eliminating the need for electric pumping equipment. This structure is naturally suited to the complex conditions of high humidity and high sediment in waterfront areas. It avoids the high-frequency failures of traditional valves, such as clogging by sediment or short circuits in electrical equipment due to water immersion. It is unaffected by power outages and conventional mechanical failures. From the block structure source, it avoids the "pseudo-low maintenance" drawbacks of traditional "smart irrigation" systems in waterfront environments, which involve frequent repairs and high maintenance costs, achieving truly long-term stable operation with low maintenance costs.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
