Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology, and in particular to a bank protection and water resource integrated utilization system based on honeycomb tube-ecological blanket. Background Technology

[0002] Islands, reefs, and similar coastal areas often face unique engineering and environmental challenges. The revetment soil in these areas is mostly composed of loose materials such as coral fragments and calcareous sand, resulting in low structural strength, poor cohesion, and weak resistance to erosion. Under the influence of frequent typhoons, torrential rains, and waves, the slopes are highly susceptible to erosion, gully development, and even shallow landslides. The toe of the slope is also frequently eroded by water flow, seriously threatening the stability and safety of shoreline facilities.

[0003] At the same time, these regions often suffer from extreme scarcity of freshwater resources. Limited area and lack of underground freshwater aquifers mean that freshwater supply is highly dependent on external transportation or energy-intensive seawater desalination, which is costly and unsustainable. Natural precipitation is a potentially reliable source of freshwater, but traditional revetment projects often harden the surface, causing rainwater to quickly form surface runoff and flow directly into the sea, failing to be effectively collected and utilized, resulting in a serious waste of water resources.

[0004] In current technological practices, bank protection and rainwater harvesting are typically designed and constructed as two independent subsystems. On the one hand, conventional bank reinforcement schemes (such as deep anchoring with honeycomb anchor pipes or surface covering with ecological blankets) mainly focus on improving mechanical stability, and their structures themselves are not designed to intercept, guide, or utilize slope rainfall, resulting in the loss of valuable freshwater resources during the protection process. On the other hand, independent rainwater harvesting systems (such as surface water collection networks, storage tanks, or seawater desalination equipment) often require additional land, rely on complex pipeline layouts and external energy supplies, and are difficult to adapt to application scenarios with limited space and weak infrastructure, such as islands and reefs.

[0005] Therefore, existing technologies generally suffer from problems of "system fragmentation" and "single function." Bank protection engineering and water resource management are isolated in design and function, resulting not only in redundant investment of materials, space, and costs, but also failing to achieve functional synergy and maximize resource utilization efficiency among engineering measures. How to integrate bank protection reinforcement with rainwater collection, purification, and utilization into a unified design, thereby ensuring bank stability while achieving in-situ collection and utilization of freshwater resources, has become a pressing technical challenge in this field. Summary of the Invention

[0012] Optionally, the V-shaped water collection trough is made of modified high-density polyethylene elastic material; in rainy weather mode, the trough wall material absorbs water and softens, and automatically unfolds under gravity to form a water guiding channel; in sunny weather mode, the trough wall material recovers its elasticity and automatically closes after the water evaporates.

[0013] Optionally, the multifunctional honeycomb anchor pipe is made of galvanized steel pipe, and the pipe body is honeycomb-shaped with multiple holes; the inside of the anchor pipe is filled with a composite filler made of ceramsite and activated carbon mixed in a volume ratio of 7:3, and the overall porosity of the composite filler is ≥40%; a water inlet hole is provided at the top of the multifunctional honeycomb anchor pipe corresponding to the water guiding and collecting layer.

[0014] Optionally, the purification and storage unit includes a purification module and a water storage tank; the purification module integrates a dual-stage filtration process of ultrafiltration membrane and reverse osmosis membrane; the water storage tank is a buried polyethylene water storage tank with a capacity of 5-10m³, and the outer wall of the tank is wrapped with a local coral sand insulation layer with a thickness of ≥20cm.

[0015] Optionally, precast concrete anti-scouring blocks are installed at the toe of the revetment slope; the double-layer composite ecological blanket extends downward to form an ecological blanket extension section, covering the wall of the intercepting ditch and embedding it into the precast U-shaped groove of the anti-scouring block, and is anchored by stainless steel bolts; the U-shaped groove is filled with a mixture of coral sand and salt-resistant adhesive.

While ensuring the mechanical safety of the bank slope, it achieves in-situ collection, purification, and storage of natural precipitation, solving the technical challenge of disconnected bank protection engineering and water resource management, and low resource utilization rates in special environments such as islands and reefs.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 5 As shown, this embodiment provides a bank protection and water resource integration system based on honeycomb tube-ecological blanket. This system integrates bank protection and rainwater harvesting and utilization functions, and is particularly suitable for slope protection projects on islands, reefs, coastlines, and other areas with scarce freshwater resources and loose soil.

[0024] This embodiment of the system includes a double-layer composite ecological blanket laid from top to bottom on the revetment slope, multifunctional honeycomb anchor pipes embedded deep into the slope at certain intervals, a water collection network connected to the flow-guiding structure of the double-layer composite ecological blanket, and a lightweight purification and storage unit driven by solar energy. The double-layer composite ecological blanket is used to protect the slope, infiltrate and collect rainwater; the honeycomb anchor pipes provide deep anchoring force while pre-treating part of the diverted rainwater; the water collection network transports the collected rainwater to the purification module 16; the purification module 16 performs deep treatment on the rainwater, and the produced freshwater is stored in an underground polyethylene water storage tank for use.

[0025] like Figure 2As shown, the double-layer composite ecological blanket in this system is laid from top to bottom on the revetment slope, that is... Figure 2 The ecological carpet paving area shown is 8. Multifunctional honeycomb anchor pipes and water collection networks are embedded deep into the slope at certain intervals, i.e. Figure 2 The location shown is 9 where the honeycomb anchor pipe is laid.

[0026] Based on the above embodiments, the double-layer composite ecological blanket further includes, from top to bottom, a protective permeability layer, a transition layer 3, and a water-conducting and collecting layer 4.

[0027] like Figure 1 As shown, in one specific embodiment, the protective permeability layer is woven from coral particles / debris 1 with a particle size of 0.5-1mm and salt-resistant polyester fibers 2, with the fiber gap strictly controlled between 1-2mm. This design effectively solves the problem that traditional ecological blankets cannot simultaneously provide surface protection and deep water permeability. Its fine fiber gaps can act as an energy dissipation layer, reducing the kinetic energy of rainwater runoff by more than 60% and effectively preventing the loss of particles from the slope surface; it can also act as a primary filter, intercepting large particles such as silt and sand.

[0028] In one specific embodiment, the transition layer 3 is a 5mm thick permeable geotextile, the main function of which is to prevent the material of the lower water-collecting layer 4 from embedding into the upper layer, thus ensuring the durability of the structure.

[0029] In one specific embodiment, the water-guiding and collecting layer 4 is a 5mm thick high-density polyethylene (HDPE) water-guiding membrane. The membrane surface is molded with V-shaped water-collecting grooves with a groove depth of 3mm and a groove spacing of 50cm. The extension direction of all V-shaped water-collecting grooves points to the slope foot to facilitate rainwater convergence.

[0030] Furthermore, at the edge of the water collection layer 4, a 50mm diameter PE water collection pipe 6 (polyethylene water collection pipe) is sealed and connected via a hot-press composite process, thereby achieving efficient collection and directional drainage of rainwater. This double-layer structure design increases the erosion resistance velocity of the ecological blanket to 2.6m / s, which is 30% higher than that of the traditional single-layer ecological blanket (2.0m / s), significantly enhancing the slope's resistance to erosion.

[0031] In one specific embodiment, the multifunctional honeycomb anchor pipe is made of galvanized steel pipe with an outer diameter of 50mm and a wall thickness of 3mm, and the pipe body has multiple holes in a honeycomb pattern. Instead of using traditional grouting materials, the interior of the multifunctional honeycomb anchor pipe is filled with a composite filler made of ceramsite and activated carbon in a 7:3 volume ratio, with an overall porosity of not less than 40%. A 10mm diameter water inlet is provided at the top of the multifunctional honeycomb anchor pipe, corresponding to the water collection layer 4. This design solves the problem of traditional anchor pipes having a single function and being unable to utilize rainwater resources. When some rainwater enters the multifunctional honeycomb anchor pipe through the water inlet and flows through the composite filler, suspended particles are filtered by the ceramsite, and dissolved organic matter and some salts are adsorbed by the activated carbon, achieving a desalination rate of not less than 30%, effectively reducing the processing load of the subsequent purification module 16. Simultaneously, the slight expansion of the composite filler after absorbing water enhances the frictional resistance with the surrounding soil, thereby improving the overall stability of the revetment during the rainy season.

[0032] Building upon the above embodiments, the system's rainwater collection, purification, and storage units further employ a modular, low-energy-consumption design. The rainwater collection network delivers rainwater to the purification module 16, which integrates ultrafiltration (UF) and reverse osmosis (RO) dual-stage filtration processes. The ultrafiltration membrane removes the vast majority of colloids, bacteria, and large organic molecules from the water, with a removal rate ≥95%. The reverse osmosis membrane performs deep desalination, ensuring that the final freshwater has a salt content not exceeding 500 mg / L, meeting the standards for domestic use.

[0033] Based on the above embodiments, the rated operating power of the entire purification module 16 is only 50W, powered by a matching 200W solar photovoltaic panel and battery pack, achieving energy self-sufficiency. The purified freshwater is stored in an underground polyethylene storage tank with a capacity of 5-10m³. 3 To maintain stable water temperature and reduce evaporation, the outer wall of the tank is wrapped with a local coral sand insulation layer with a thickness of not less than 20cm. At the connection between the PE water collection pipe 6 and the inlet of the purification module 16, a one-way drain valve 15 is installed. This valve only allows rainwater to flow in one direction, which can effectively prevent seawater backflow during storm surges and protect the purification system.

[0034] Furthermore, to ensure the sealing reliability of the connections between the various components of the system, a U-shaped stainless steel buckle 5 is installed at the connection between the edge of the water-guiding and collecting layer 4 and the multi-functional honeycomb anchor pipe or water collection network. This U-shaped stainless steel buckle 5 fixes the edge of the water-guiding membrane by mechanical locking and, together with a nitrile rubber sealing gasket, ensures the sealing of the rainwater collection channel.

[0035] Furthermore, a coral sand cushion layer 17 is laid at the bottom of both the intercepting ditch and the foundation of the buried polyethylene water storage tank. This coral sand cushion layer 17 utilizes local coral sand material to filter, drain, and buffer foundation stress, thereby enhancing the long-term stability and environmental adaptability of the system.

[0036] like Figure 5 As shown, the system in this embodiment possesses an adaptive collaborative working mechanism based on material properties. The V-shaped water collection trough used in the water-guiding and collecting layer 4 is made of modified high-density polyethylene elastic material. In rainy weather mode, when the rainfall reaches or exceeds 5mm, the trough wall material softens due to water absorption and automatically unfolds under gravity to form a smooth water-guiding channel, and the system enters a highly efficient water collection state with a water collection rate ≥70%. At the same time, the ceramsite-activated carbon filler in the honeycomb anchor pipe undergoes slight expansion after absorbing water, enhancing the frictional resistance with the surrounding soil, thereby improving the overall stability of the revetment during the rainy season. In sunny weather mode, as the moisture in the material evaporates, the V-shaped water collection trough gradually closes automatically due to elastic recovery. The closed trough reduces the ineffective evaporation of slope moisture, playing a role in moisture retention, and also helps maintain the temperature and humidity stability of the slope microenvironment without affecting the normal growth of vegetation on the ecological carpet. This working mechanism is completely passively triggered, requiring no external sensors or energy drive, realizing intelligent collaboration of "using water to stabilize the slope and using the slope to nourish water".

[0037] Building upon the above embodiments, to further enhance the erosion resistance of the slope toe, precast concrete anti-scouring blocks 10 are installed at the toe of the revetment slope. A double-layer composite ecological blanket extends downwards to form an ecological blanket extension section 11, covering the intercepting ditch wall and embedding into the precast U-shaped groove 12 of the anti-scouring block, and is finally anchored using stainless steel bolts 13. The U-shaped groove 12 is filled with a mixture of coral sand and salt-resistant adhesive 14 to enhance sealing and fixation.

[0038] Furthermore, a one-way drain valve 15 is installed at the connection between the water collection pipe and the inlet of the purification module 16. This one-way drain valve 15 only allows rainwater to flow into the purification module 16 in one direction, effectively preventing seawater backflow during storm surges and protecting the purification system. Specifically, as shown below... Figure 3 As shown.

[0039] Furthermore, a trapezoidal earthen embankment 7 with a height of 10cm (8cm at the top and 15cm at the bottom) is constructed at the top of the slope, and a water interception ditch with a cross section of 30cm×30cm is excavated at the bottom of the slope to systematically guide and collect the slope runoff.

[0040] The construction and implementation of the bank protection and water resource comprehensive utilization system based on honeycomb tube-ecological blanket in this embodiment can follow the following process: S1. Slope Pretreatment: Manually remove coral particles or debris larger than 10cm in diameter from the slope. Compact the slope using a small vibratory roller weighing no more than 0.5 tons to achieve a surface compaction degree of 85% to 90%. Construct a water-retaining earthen embankment at the top of the slope and excavate a drainage ditch at the toe of the slope.

[0041] S2. Laying and Fixing of Ecological Mat: Lay a double-layer composite ecological mat with dimensions of 5m × 2m (total thickness 25mm) along the slope from top to bottom, allowing for 5% to 8% material expansion and contraction during laying. The overlap width between adjacent ecological mats is 15cm. The overlap seam is first double-seamed with a width of 5cm and then sewn a second time using nylon rope. Fix the mats using 304 stainless steel threaded anchors with a diameter of 12mm and a length of 25cm at 1.0m intervals, and install nitrile rubber washers under the pressure plate on the top of the anchors.

[0042] S3. Honeycomb Anchor Pipe Installation and System Connection: Install honeycomb anchor pipes at a grid spacing of 2m×2m, ensuring that their ends penetrate at least 2m into the stable rock layer. Make holes at the corresponding locations on the ecological blanket to connect the water inlet at the top of the anchor pipe with the water collection layer 4. Connect the water collection pipe to the main water collection network at the slope toe and finally connect it to the inlet of the purification module 16.

[0043] S4. Post-construction maintenance and vegetation synergy: Sow salt-tolerant plant seeds (such as purslane) on the upper layer of the ecological carpet at a rate of 20g / m². 2 Initially, collected rainwater was used for irrigation and maintenance.

[0044] It should be understood that, in practical applications, some materials and structures of this system may be adjusted according to the specific environment.

[0045] In some embodiments, the fiber material of the upper layer of the ecological blanket can be replaced with other salt-resistant plant fibers (such as coconut shell fiber) or high-performance synthetic fibers, provided that the requirements for erosion resistance and permeability are met.

[0046] In some embodiments, the filling material of the honeycomb anchor tube may also be replaced with other material combinations that have similar porous adsorption properties, such as zeolite, diatomaceous earth, etc.

[0047] In some embodiments, the purification module 16 may also consider alternative technologies such as electrodialysis for its deep desalination unit, provided that the effluent quality and energy consumption are guaranteed.

[0048] In some embodiments, the energy supply method can also be expanded to a solar and wind power complementary mode to further enhance the system's environmental adaptability.

[0049] These alternative solutions all adhere to the core idea of ​​this invention: to integrate bank protection reinforcement with water resource collection and utilization.

[0050] Through the above integrated design, the system of the present invention has achieved significant technical effects, specifically reflected in the following four aspects: A fundamental improvement in resource utilization efficiency: the system converts rainwater, which is traditionally discharged directly into the sea, into usable freshwater. The ecological blanket has a water collection rate of no less than 70%, and combined with a low-energy dual-membrane purification process, it can achieve a water yield of 700m². 2 Under a single rainfall of 20mm, approximately 9.8m³ of water can be collected and produced. 3 The qualified freshwater can continuously meet the living and miscellaneous needs of a group of 3-6 people, providing a sustainable solution to the problem of freshwater scarcity on islands and reefs.

[0051] Synergistic Enhancement of Bank Protection Performance: The system's dual functions create a synergistic enhancement effect. The double-layer structure of the ecological blanket increases the scour velocity resistance from 2.0 m / s in the traditional scheme to 2.6 m / s. Geotechnical centrifuge model tests have verified that, under the same working conditions, after the honeycomb anchor pipe filler absorbs water, the bank revetment's anti-sliding stability coefficient can increase from 1.5 to 1.8, significantly enhancing overall stability.

[0052] Comprehensive assurance of adaptability to extreme environments: For harsh environments with high temperature, high salt and strong scouring, the system has been optimized in all aspects from material corrosion resistance, structural design (with reserved expansion and contraction, and reinforced slope foot) to adaptive working mechanism, to ensure that the core functions do not fail under long-term harsh conditions, and the system design life is no less than 15 years.

[0053] Convenience of construction and operation: All components adopt a modular and lightweight design, simplifying the construction process and eliminating the need for large heavy machinery, perfectly adapting to the limited construction conditions on islands and reefs. Only periodic inspections and localized repairs are required later, resulting in low maintenance costs.

[0054] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0055] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
