Description

Technical Field

[0001] This invention belongs to the field of ecological flood control dams, specifically a method for constructing ecological flood control dams using rural waste. Background Technology

[0002] Every year, my country's vast rural areas generate a large amount of crop straw, reeds, weeds, tree branches and leaves, and livestock and poultry breeding waste. These wastes are scattered, bulky, and complex in composition, making them difficult to handle. In the field of flood control and disaster reduction, especially along riverbanks and around reservoirs, a large amount of manpower and resources are needed every summer and autumn for the construction and reinforcement of flood control dams. Traditional flood control dam structures mainly rely on materials such as sandbags, boulders, and willow bundles. These traditional materials and methods have many inherent defects: First, sandbags and boulders are expensive, and their extraction and transportation consume a lot of resources. They also damage the natural landform and original ecosystem, forming hard "gray" infrastructure that hinders water and soil exchange and ecological continuity. Second, although willow bundles and tree branches have a certain degree of flexibility and ecological potential, their material sources and specifications are not uniform. Relying on manual binding and laying results in low construction efficiency, making it difficult to form a durable and stable engineering structure. Moreover, their flood control effectiveness rapidly decreases as the materials decompose.

[0003] Existing technologies also include some attempts to use waste for ecological restoration, such as simply bundling straw and piling it on the riverbank, or directly covering the slope with crushed material. However, simply bundling or covering waste is loose and easily washed away by water flow, failing to form a flood control dam with sufficient erosion resistance and structural stability. Its flood control efficiency is far lower than that of traditional engineering materials. At the same time, plant seeds directly mixed in or sown are easily blown away by wind and water, resulting in a low germination rate. Furthermore, due to the lack of a stable substrate environment and continuous water and fertilizer supply, the survival rate and long-term growth of seedlings are difficult to guarantee. The ecological slope protection effect has great uncertainty and delay, and it is impossible to quickly and effectively form a soil-stabilizing root network.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a method for constructing ecological flood control dams using rural waste. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a method for constructing ecological flood control dams using rural waste, thereby solving the problem in the prior art of transforming complex and difficult-to-process rural waste into modular waterproof components with stable performance and immediate flood control effectiveness.

[0006] A method for constructing an ecological flood control dam using rural waste includes the following steps: S1: crushing one or more types of rural waste, such as crop straw, weeds, reeds, and branches;

[0007] S2: Mix the crushed material with plant seeds;

[0008] S3: Compact the mixed materials and fill them into a permeable ecological box;

[0009] S4: Transport the ecological container filled with the aforementioned material to the flood control dam construction site;

[0010] S5: Stack and lay multiple of the aforementioned ecological boxes on the riverbank to form a flood control dam;

[0011] S6: Connect the stacked ecological boxes to each other and anchor them to the foundation.

[0012] Preferably, in step S2, a water-retaining agent and fertilizer are also added to the material; the water-retaining agent is a starch-grafted acrylate water-retaining agent, and the fertilizer is a slow-release organic fertilizer; the mass ratio of the water-retaining agent, fertilizer, and plant seeds is (5-8):(15-25):(1-3); after addition, a dual-shaft differential speed mixer is used for stirring.

[0013] Preferably, the plant seeds are drought-resistant mixed grass and shrub seeds with well-developed root systems, and their composition by weight includes 2-4 parts of Populus euphratica seeds, 3-5 parts of Hippophae rhamnoides seeds, 4-6 parts of Caragana korshinskii seeds, and 1-2 parts of alfalfa seeds. Before mixing, the mixed seeds are soaked in a gibberellin solution with a concentration of 50-100 mg / L to promote germination for 12-24 hours, then taken out and dried until the surface is slightly dry before mixing.

[0014] Preferably, the preprocessing step S1 specifically includes,

[0015] S1a: First, a twin-shaft shearing coarse crusher with a pre-compression roller is used to initially crush and shear the loose straw and reeds. The gap between the pre-compression roller and the cutter shaft is 50-100mm.

[0016] S1b: Then the coarsely crushed material, along with hard branches and livestock and poultry waste, is fed into a vertical hammer mill equipped with carbide hammers for secondary crushing.

[0017] S1c: Finally, the material with a particle size of less than 8cm is sent to the mixing step through the vibrating screen, while the material with a particle size greater than 8cm is returned to the inlet of the fine crusher.

[0018] Preferably, in step S3, a four-column hydraulic press is used to press the material into the ecological box in two layers; after the first layer is filled to half the height of the box, a first-level pressure is applied for pre-compaction, the first-level pressure being 5-8 MPa; after the second layer is filled, a second-level pressure is applied for final compaction, the second-level pressure being 12-18 MPa, and the top surface of the material inside the box is 5-10 cm lower than the upper edge of the box.

[0019] Preferably, the ecological box is a double-twisted hexagonal mesh structure woven from aluminum-zinc alloy steel wire, with a mesh diameter of 60-80mm, and a connecting ring made of the same mesh extending from the side of the box.

[0020] Preferably, step S6 includes vertical anchoring and lateral connection. The vertical anchoring is achieved by using a hydraulically driven hammer to drive a hollow steel pipe nail into the foundation through a reserved hole on the top surface of the ecological box, to a depth of not less than 1m, and then injecting cement mortar into the hollow steel pipe nail.

[0021] The lateral connection is achieved by using U-shaped high-strength steel rebar connectors, which pass through the connecting rings on the sides of adjacent boxes in sequence, and are tightened and locked with nuts at both ends, so that the boxes on the same layer are connected as a whole.

[0022] Preferably, in step S5, the hollow steel pipe ground nails of the lowest layer box are driven into the ground at a downward angle of 0-15°, and the ground nails of the uppermost layer box are driven into the ground at an upward angle of 0-15°.

[0023] Preferably, in step S5, the ecological boxes are stacked in a staggered manner, and a non-woven geotextile mat made of discarded fishing nets or old clothes is laid between the upper and lower boxes, and the unit area mass of the geotextile mat is not less than 200g / m².

[0024] Preferably, in step S5, an intelligent tracked transport vehicle integrating a GNSS positioning system and an inertial measurement unit (IMU) is used for construction. The transport vehicle automatically grabs, precisely positions, and stacks the ecological boxes according to the pre-input three-dimensional design model of the flood control dam through the multi-degree-of-freedom robotic arm, and records and feeds back the actual laying position data of each box to the central control system, so as to realize digital management and quality traceability of the construction process.

[0025] Through the above technical solutions

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. This invention successfully transforms scattered, loose, and easily polluting waste into structurally stable and uniformly sized modular flood control components by crushing rural waste, mixing it with seeds, compacting it, filling it into a permeable ecological container, and then mechanically stacking and anchoring it. This method not only realizes the resource utilization of waste and avoids environmental pollution, but also constructs a flood control dam with both immediate erosion resistance and long-term ecological self-repair function, effectively solving the problems of poor structural performance, random ecological effects, and low construction efficiency of traditional waste utilization methods.

[0028] 2. This invention, through specific material ratios, seed pretreatment processes, multi-stage crushing and layered compaction methods, and innovative box-type structures and intelligent anchoring systems, further ensures the initial stability of the flood control dam, seed germination rate, and survival rate, and achieves precise, automated, and digital management of the construction process. Ultimately, it forms an economical, efficient, eco-friendly, sustainable, and easily scalable ecological flood control dam construction technology system, comprehensively improving the performance, durability, and environmental benefits of flood control projects. Attached Figure Description

[0029] Figure 1 This is a flowchart of the overall method steps of the present invention. Detailed Implementation

[0030] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0031] Example 1: As shown in the attached document Figure 1 As shown: This invention provides a method for constructing ecological flood control dams using rural waste, including the following steps: S1: crushing one or more types of rural waste, such as crop straw, weeds, reeds, and branches and leaves;

[0032] S2: Mix the crushed material with plant seeds;

[0033] S3: Compact the mixed materials and fill them into a permeable ecological box;

[0034] S4: Transport the eco-friendly containers filled with materials to the flood control dam construction site;

[0035] S5: Multiple ecological containers are stacked and laid on the riverbank to form a flood control dam;

[0036] S6: Connect the stacked ecological boxes to each other and anchor them to the foundation.

[0037] Preferably, in step S2, a water-retaining agent and fertilizer are also added to the material; the water-retaining agent is a starch-grafted acrylate water-retaining agent, and the fertilizer is a slow-release organic fertilizer; the mass ratio of water-retaining agent, fertilizer, and plant seeds is (5-8):(15-25):(1-3); after addition, a twin-shaft differential speed mixer is used to stir at a speed of 30-40 rpm for 5-8 minutes to ensure that each component is evenly distributed in the crushed material. This step specifies the specific types of water-retaining agent and fertilizer (starch-grafted acrylate, slow-release organic fertilizer), and provides a precise mass ratio and specific mixing equipment and process parameters to ensure that seeds can germinate and grow efficiently and synergistically in arid riverbank environments.

[0038] Preferably, the plant seeds are drought-resistant mixed grass and shrub seeds with well-developed root systems. The composition, by weight, includes 2-4 parts of Populus euphratica seeds, 3-5 parts of Hippophae rhamnoides seeds, 4-6 parts of Caragana korshinskii seeds, and 1-2 parts of alfalfa seeds. Before mixing, the mixed seeds are soaked in a gibberellin solution with a concentration of 50-100 mg / L to promote germination for 12-24 hours. They are then taken out and dried until the surface is slightly dry before mixing. Instead of mixing, a water-retaining agent and slow-release fertilizer with a specific ratio are added to create a water- and fertilizer-rich "microenvironment" for the germination and early growth of the plant seeds. Using gibberellin to promote germination of the grass and shrub seeds with a specific ratio greatly improves the germination rate and survival rate of the seeds, ensuring the reliability and timeliness of the ecological effect.

[0039] Furthermore, the plant seeds are drought-resistant mixed grass and shrub seeds with well-developed root systems. The composition, by weight, includes 2-4 parts of Populus euphratica seeds, 3-5 parts of Hippophae rhamnoides seeds, 4-6 parts of Caragana korshinskii seeds, and 1-2 parts of alfalfa seeds. Before mixing, the mixed seeds are soaked in a gibberellin solution with a concentration of 50-100 mg / L to promote germination for 12-24 hours, then taken out and dried until the surface is slightly dry before mixing.

[0040] Specifically, the pretreatment step S1 includes S1a: First, a twin-shaft shear crusher with a pre-compression roller is used to initially crush and shear the loose straw and reeds. The gap between the pre-compression roller and the cutter shaft is 50-100mm.

[0041] S1b: Then the coarsely crushed material, along with hard branches and livestock and poultry waste, is fed into a vertical hammer mill equipped with carbide hammers for secondary crushing.

[0042] S1c: Finally, the material with a particle size of less than 8cm is sent to the mixing step through the vibrating screen, while the material with a particle size greater than 8cm is returned to the inlet of the fine crusher. The loose straw and reeds are processed by the "pre-compression roller coarse crushing" to solve the problem of easy entanglement and difficulty in efficient crushing. The hard branches are processed by the "hammer crushing" to ensure that the final material has a uniform particle size. The screening and return mechanism ensures the crushing quality.

[0043] Furthermore, in the filling step S3, a four-column hydraulic press is used to press the material into the ecological box in two layers; after the first layer is filled to half the height of the box, the first level of pressure is applied for pre-compaction, which is 5-8 MPa; after the second layer is filled, the second level of pressure is applied for final compaction, which is 12-18 MPa, and the top surface of the material inside the box is 5-10 cm lower than the upper edge of the box, so as to reserve space for seed germination and rainwater storage.

[0044] Furthermore, the ecological box is a double-twisted hexagonal mesh structure woven from aluminum-zinc alloy steel wire, with a mesh diameter of 60-80mm. Connecting rings made from the same mesh surface are provided on the side of the box. Anchoring step S6 includes vertical anchoring and lateral connection. Vertical anchoring is achieved by using a hydraulically driven hammer to drive a hollow steel pipe nail into the foundation through a reserved hole on the top surface of the ecological box to a depth of not less than 1m. Cement mortar is then injected into the hollow steel pipe nail. Lateral connection is achieved by using U-shaped high-strength steel rebar connectors, which are passed through the connecting rings on the sides of adjacent boxes in sequence, and nuts are fitted at both ends for tensioning and locking, so that the boxes on the same layer are connected as a whole.

[0045] Specifically, in step S5, the ecological boxes are stacked in a staggered manner, and a non-woven geotextile mat made of discarded fishing nets or old clothes is laid between the upper and lower boxes. The unit area mass of the geotextile mat is not less than 200g / m².

[0046] As can be seen from the above, when using the system, loose materials such as straw and reeds collected from rural areas are first fed into a twin-shaft shear crusher with pre-compression rollers for initial crushing and shearing. Subsequently, they are fed into a vertical hammer mill for secondary crushing along with hard waste materials such as branches. After being screened by a vibrating screen, qualified materials are sent out, while oversized materials are returned to the crusher for reprocessing.

[0047] The pulverized material is conveyed to the mixing chamber. Simultaneously, mixed grass and shrub seeds (poplar, sea buckthorn, caragana, alfalfa), pre-soaked in gibberellin solution to promote germination and then dried to a slightly crisp state, are added to the chamber along with a specific ratio of starch-grafted acrylate water-retaining agent and slow-release organic fertilizer. The dual-shaft differential speed mixer is started and runs at a specific speed for several minutes to ensure uniform mixing of all components.

[0048] The mixed materials are sent to the filling station. After the empty ecological boxes (aluminized zinc alloy steel wire mesh boxes) are fixed, the materials are filled in two layers. When the first layer is filled to half the height, the four-column hydraulic press applies the first level of pressure for pre-compaction. After the second layer is filled, the hydraulic press applies a greater second level of pressure for final compaction, and ensures that the top surface of the material after compaction is lower than the upper edge of the box, leaving room for seed growth.

[0049] The filled ecological containers are transported to the riverbank construction site by intelligent transport vehicles. Based on the built-in 3D model of the flood control dam, the transport vehicles automatically grab the containers using their robotic arms and precisely stack them using a staggered stacking method. During the stacking process, the operator controls a hydraulically driven hammer to drive hollow steel pipe ground nails into the foundation to the specified depth at the designed angle (the bottom layer tilts downwards and the top layer tilts upwards). Then, cement mortar is poured into the ground nails to complete the vertical anchoring. At the same time, U-shaped high-strength steel bars are used to pass through the connecting rings of adjacent containers and are tightened with nuts to complete the lateral connection. Between the upper and lower container layers, a layer of non-woven geotextile made from discarded fishing nets is laid.

[0050] After construction, minimal maintenance is required. Relying on natural rainfall, the water-retaining agent inside the enclosure provides initial moisture for seed germination, while slow-release fertilizer provides continuous nutrition. The seeds germinate rapidly, and their roots penetrate the net cages and reach deep into the foundation soil. Several months later, the plants grow vigorously, and their root network tightly binds the entire flood control dam into a robust and vibrant ecological whole.

[0051] Example 2: As shown in the attached document Figure 1 As shown: This embodiment is basically the same as the previous embodiment, except that in the laying step S5, the hollow steel pipe ground nails of the bottom box are driven into the ground at a downward angle of 0-15°, and the ground nails of the top box are driven into the ground at an upward angle of 0-15°, forming an anti-overturning anchoring system.

[0052] As can be seen from the above, overturning resistance is the primary requirement in steep slope environments. Therefore, during the laying and anchoring processes, intelligent transport vehicles or construction personnel will more precisely control the driving angle of the ground stakes. The ground stakes for the lowest layer of boxes will be driven in at a downward angle of approximately 15 degrees to maximize the anchoring force against the downward slippage of the dam body, while the ground stakes for the highest layer of boxes will be driven in at an upward angle to create a "holding" effect on the dam body, together forming a torque system to resist overturning.

[0053] Furthermore, the non-woven geotextile layer between the layers plays a crucial role in this embodiment. It effectively prevents the slope soil from being eroded through the gaps in the box structure during heavy rain or a sudden drop in water level, ensuring the long-term stability of the slope. Its ecological restoration function is also more significant because, on steep slopes, the box system creates a rare stable growth platform for plants, accelerating the process of vegetation coverage and reinforcement of the slope.

[0054] Example 3: As shown in the attached document Figure 1 As shown: Based on Embodiment 1, this method also includes a central intelligent control system. This system runs through all steps from waste pretreatment to final anchoring acceptance. In laying step S5, an intelligent tracked transport vehicle integrating a GNSS positioning system and an inertial measurement unit (IMU) is used for construction. The transport vehicle automatically grabs, precisely positions, and stacks the ecological boxes according to the pre-input three-dimensional design model of the flood control dam through a multi-degree-of-freedom robotic arm, and records and feeds back the actual laying position data of each box to the central control system, realizing digital management and quality traceability of the construction process.

[0055] As can be seen from the above, this method introduces a central intelligent control system that runs through all steps from waste pretreatment to final anchoring acceptance.

[0056] The process begins with a 3D dam design model based on remote sensing imagery and a Geographic Information System (GIS). This model not only determines the shape of the dam but also precisely calculates the spatial coordinates of each ecological enclosure, the required material volume, and the seed ratio.

[0057] During the pretreatment stage, the operating parameters of the crushing equipment (such as the gap between the cutter rollers and the screen size) are adaptively adjusted by the central system according to the type of waste input (such as pure straw or mixed with branches) to ensure that the particle size of the output material always meets the requirements. In the mixing stage, the seed hopper and the water-retaining agent / fertilizer bin are automatically fed by the system according to the current batch material volume and the preset optimal ratio, eliminating human error in the ratio.

[0058] The filling process is a key aspect of quality control. The pressure sensors of the four-column hydraulic press feed data back to the system in real time, ensuring that the compaction density of each container is strictly controlled within the specified range (e.g., 450-600 kg / m³). Each completed eco-friendly container is assigned a unique electronic identifier (such as an RFID tag or QR code) that records key data such as its production batch, filling time, compaction density, and seed information.

[0059] The transportation and laying process utilizes an intelligent tracked transport vehicle integrated with a GNSS positioning system and an inertial measurement unit (IMU). Receiving task instructions and 3D model data from a central system, the transport vehicle, through its multi-degree-of-freedom robotic arm, automatically grasps the marked containers and precisely delivers them to the locations specified by the GNSS coordinates. The robotic arm, fine-tuned by the IMU, stacks the containers into place with extremely high precision (centimeter-level). The entire laying process requires no human intervention, achieving unmanned and automated construction.

[0060] During the anchoring process, when the hydraulically driven hammer is used to install the ground nail, its driving depth and inclination angle data are recorded in real time and linked to the electronic tag of the box. Similarly, the amount of cement mortar used is also recorded.

[0061] Ultimately, all data—from the source of raw materials to the production data, precise location, and anchoring data of each container—is uploaded to the big data platform of the central control system, generating a "digital twin" of the entire flood control dam. This not only enables digital quality traceability of the construction process, but more importantly, it provides a data foundation for subsequent long-term monitoring and intelligent operation and maintenance, thereby achieving precise and low-cost maintenance.
