Description

Technical Field

[0001] This invention relates to the field of ecological and environmental protection technology, specifically to a three-dimensional soil stabilization net mat for micro-drip irrigation and its preparation method. Background Technology

[0002] Three-dimensional soil stabilization netting, also known as geotextile mat, three-dimensional geotextile mat, three-dimensional vegetation net, and three-dimensional grass planting net, is a new type of civil engineering material. It is a three-dimensional, loofah-like netting mat used for planting grass and stabilizing soil. It can effectively solve the problem of protecting rock slopes and steep slopes. It is a new technology that constructs a protective system with its own growth capacity on the slope surface and strengthens the slope through the growth of plants. According to the characteristics of slope topography, soil quality, and regional climate, a layer of geosynthetic material is covered on the slope surface and various plants are planted in a certain combination and spacing. Through the growth activities of plants, the root system is reinforced and the stems and leaves are protected against erosion. After ecological slope protection technology, a dense vegetation cover can be formed on the slope surface, and an intricate root system can be formed in the topsoil layer. This effectively inhibits the erosion of the slope by rainwater runoff, increases the shear strength of the soil, reduces pore water pressure and soil self-weight, thereby significantly improving the stability and erosion resistance of the slope.

[0003] Existing three-dimensional geonets consist of multiple layers of plastic convex and concave mesh and biaxially oriented planar mesh, which are bonded together at the junctions through heat fusion to form a stable three-dimensional mesh structure. The surface layer has an uneven appearance and a loose and flexible material, leaving more than 90% of the space for filling with soil and sand. The bottom layer of biaxially oriented mesh has the characteristics of low elongation and high strength, which plays a role in preventing slope slippage. The roots of plants can comfortably and evenly penetrate through the entire vegetation mesh, reaching a depth of 0.5-2 meters underground. In this way, the vegetation, mesh, and soil form a strong composite mechanical interlocking system, thereby achieving the purpose of protecting the slope.

[0004] The existing three-dimensional geonet is installed on the slope, and an irrigation device is installed at the top of the slope to provide irrigation water for the three-dimensional geonet. However, the three-dimensional geonet has a certain length, so the three-dimensional geonet closer to the irrigation device receives irrigation water first and is irrigated first, while the three-dimensional geonet farther away from the irrigation device has to wait for a considerable amount of time to receive irrigation water. During the waiting period, the three-dimensional geonet closer to the irrigation device continues to irrigate, causing the irrigation water along the irrigation line to gradually decrease from near to far, resulting in uneven irrigation. Summary of the Invention

[0005] This invention provides a three-dimensional soil stabilization net mat for micro-drip irrigation and its preparation method to solve the problem of uneven irrigation caused by the long irrigation lines of existing three-dimensional geonet irrigation equipment.

[0006] To achieve the above objectives, the present invention provides the following solution:

[0007] The micro-drip irrigation three-dimensional soil stabilization net mat includes an irrigation device and a three-dimensional soil stabilization net mat, and also includes a micro-drip irrigation component connected to the three-dimensional soil stabilization net mat. The micro-drip irrigation component includes a plurality of reinforcing ribs for transmitting fluid and a plurality of micro-drip irrigation switches disposed on the reinforcing ribs. The micro-drip irrigation switches are used to control the speed at which fluid is drawn from the reinforcing ribs.

[0008] This invention controls the speed at which the micro-drip irrigation component draws fluid from the reinforcing ribs by using a micro-drip irrigation switch, thereby controlling the irrigation speed of the micro-drip irrigation component near the irrigation device. This prevents the component from being at its own irrigation speed limit for an extended period, which would otherwise lead to a reduction in irrigation water, a delay in the acquisition time, or even an inability to acquire enough irrigation water, resulting in uneven irrigation.

[0009] Furthermore, the micro-drip irrigation switch includes a water guide nail and a water-absorbing component installed on the upper end of the water guide nail. The water guide nail has a plurality of water guide grooves, which are connected to the interior of the reinforcing rib. The upper end of the water guide groove is in contact with the water-absorbing component.

[0010] By nailing water guide nails into the reinforcing ribs, the fluid inside the reinforcing ribs seeps into the water-absorbing component through the water guide channel, and then the water-absorbing component drips the fluid into the soil. The structure is simple and the drip irrigation effect is good. At the same time, the water guide nails can also fix the reinforcing ribs. By nailing water guide nails at the intersection of two reinforcing ribs, not only are the two reinforcing ribs fixed, but the fluid inside the two reinforcing ribs can also be guided into the water-absorbing component at the same time, which enhances the conduction and utilization efficiency of irrigation water in the micro-drip irrigation three-dimensional soil stabilization net mat.

[0011] Furthermore, the micro-drip irrigation switch also includes a water guiding part and a piston part connected to each other. The water suction component has a cavity inside for accommodating the water guiding part. The lower end of the water suction component has a notch for the water guiding nail to pass through. The piston part is installed in the water guiding groove. The lower end of the water guiding part is provided with several thrust elastic elements.

[0012] Because the water channel is a cavity, irrigation water can only be guided into the water suction unit when it is filled. This results in a slow start-up speed for irrigation using the micro-drip irrigation three-dimensional soil stabilization net mat. Therefore, by filling the water channel with the piston part, the irrigation start-up speed of the micro-drip irrigation three-dimensional soil stabilization net mat is accelerated. At the same time, the rise and fall of the water channel and piston part are controlled by the weight of the water channel and the thrust elastic element, which controls the contact area between the reinforcing rib, piston part and water channel, and controls the size and speed of the irrigation water passing through, thereby controlling the irrigation speed of the micro-drip irrigation component.

[0013] Furthermore, the piston portion includes an opening section located below and a closing section located above, with the outer side of the closing section covered by a waterproof layer.

[0014] When irrigation water passes through the reinforcing rib, it permeates through the piston section and the water guide groove into the water guide section. The water guide section then permeates the irrigation water into the water suction component, which then consumes the irrigation water for drip irrigation. When the irrigation water absorbed by the micro-drip irrigation component exceeds the irrigation water consumed by drip irrigation, the irrigation water accumulated in the water guide section increases, increasing its weight. This, in turn, compresses the thrust elastic component, causing the piston section to move downward. The contact area between the closing section above the piston section and the reinforcing rib increases. Due to the isolation of the waterproof layer, the irrigation water absorbed by the micro-drip irrigation component decreases or even stops. The continuous drip irrigation by the water suction component reduces the irrigation water accumulated in the water guide section, lightening its weight. The thrust elastic component pushes the water guide section upward, further reducing the contact area between the closing section above the piston section and the reinforcing rib. This achieves a dynamic balance between the irrigation water absorbed and consumed by the micro-drip irrigation component, preventing the micro-drip irrigation component from continuously absorbing large amounts of irrigation water, which would lead to a decrease in the irrigation water obtained by subsequent micro-drip irrigation components.

[0015] Furthermore, the upper end of the water guiding part is provided with several water guiding strips connected to the water absorption element.

[0016] Because the water guide needs to move up and down, there is a gap between the water guide and the water suction component, which affects the penetration of irrigation water. The water guide belt can allow irrigation water to pass through and maintain the connection between the water guide and the water suction component.

[0017] Furthermore, the water guiding part, piston part, and water guiding strip are all made of water guiding material, and the outer side of the piston part is in contact with the reinforcing rib.

[0018] Furthermore, a fluid channel is provided inside the reinforcing rib, and the fluid channel is filled with a water-conducting material for conducting fluid. The micro-drip irrigation switch and the irrigation device are both connected to the fluid channel.

[0019] Furthermore, the water-conducting material includes porous fiber cotton filaments.

[0020] By setting reinforcing ribs and porous fiber cotton inside, the water conveyance function is realized and the strength of the three-dimensional soil stabilization net is improved. The porous fiber cotton is made up of countless fine fibers interwoven together, forming a huge number of micropores. This not only increases the surface area of ​​the material, but also provides abundant channels for water to flow and be stored, so that the porous fiber cotton can effectively adsorb and store water, air and nutrients.

[0021] When rainwater or other water sources come into contact with porous fiber cotton, the water spreads rapidly on the fiber surface and forms tiny droplets between the fibers due to surface tension. These droplets are then captured by the tiny pores between the fibers and gradually diffuse and store within the fiber network. Because fiber materials typically have good hydrophilicity, they can strongly attract and retain moisture, thus achieving a highly efficient water absorption process. When the porous fiber cotton reaches saturation, excess water passes through the fiber layer, acting as a filter and drain, but most of the water remains tightly locked in the fiber network. Under natural conditions, even without contact with soil or sand, the porous fiber cotton experiences minimal water loss due to gravity. When the porous fiber cotton reaches saturation or needs to release water, its unique fiber structure and pore distribution ensure rapid and uniform drainage. Upon contact with dry soil or other substances with strong capillary force, the porous fiber cotton can release more than 60% of its stored water in a short time, providing necessary water replenishment for plant roots. Simultaneously, the porous fiber cotton requires no external energy consumption throughout the entire drainage process, achieving a natural and efficient drainage effect.

[0022] In addition to its excellent water conductivity, porous fiber cotton also possesses good eco-friendly characteristics and sustainable development potential. Made from natural fibers and pollution-free materials, it is non-toxic, harmless, and environmentally friendly. Its durability and long lifespan allow it to be reused multiple times without easily breaking or deforming, helping to reduce material waste and environmental pollution. Furthermore, porous fiber cotton has good air permeability and antibacterial properties, maintaining root health and a healthy growth environment, and reducing the occurrence of diseases.

[0023] Furthermore, the reinforcing rib is provided with several water delivery pipes arranged parallel to the fluid channel, and the space between the water delivery pipes and the fluid channel is filled with water-conducting material.

[0024] Because the area covered by the three-dimensional soil stabilization netting for micro-drip irrigation is large, the micro-drip irrigation components at the end may not receive irrigation water for a long time. Therefore, irrigation water is delivered through the water supply pipe set in the reinforcing ribs. At the same time, irrigation water is supplemented into the water supply pipe through the permeation of the water-conducting material, which can reduce the amount of irrigation water absorbed by the micro-drip irrigation components at the front end.

[0025] The preparation method of the three-dimensional soil stabilization netting for micro-drip irrigation includes:

[0026] Preparation of reinforcing ribs: Porous fiber cotton is made into threads, and then single or multiple porous fiber cotton threads are made into polypropylene porous fiber cotton reinforcing ribs by extrusion molding with high-strength polypropylene material.

[0027] Install micro-irrigation switches: Arrange multiple reinforcing ribs in a cross pattern to form a grid, and install micro-irrigation switches at the intersections of the grid.

[0028] The three-dimensional soil stabilization mesh is obtained by using a polypropylene melt-blowing process to spray polypropylene onto the mesh formed by the reinforcing ribs.

[0029] One or more technical solutions provided by this invention have at least the following technical effects or advantages:

[0030] (1) The present invention controls the speed at which the micro-drip irrigation component draws fluid from the reinforcing rib by controlling the micro-drip irrigation switch, thereby controlling the irrigation speed of the micro-drip irrigation component close to the irrigation device, preventing it from being at the upper limit of its own irrigation speed for a long time, which would lead to a reduction in irrigation water obtained by the subsequent micro-drip irrigation component, a delay in the acquisition time, or even an inability to obtain enough irrigation water, resulting in uneven irrigation.

[0031] (2) By nailing the water guide nail into the reinforcing rib, the fluid in the reinforcing rib can seep into the water suction device through the water guide groove, and then the fluid is dripped into the soil through the water suction device. The structure is simple and the drip irrigation effect is good. At the same time, the water guide nail can also fix the reinforcing rib. By nailing the water guide nail at the intersection of the two reinforcing ribs, not only are the two reinforcing ribs fixed, but the fluid in the two reinforcing ribs can also be guided into the water suction device at the same time, which enhances the conduction and utilization efficiency of irrigation water in the micro-drip irrigation three-dimensional soil stabilization net mat.

[0032] (3) By filling the water guide groove with the piston part, the irrigation start speed of the micro-drip irrigation three-dimensional soil stabilization net mat is accelerated. At the same time, the rise and fall of the water guide part and the piston part are controlled by the weight and thrust elastic element of the water guide part, the contact area between the reinforcing rib, the piston part and the water guide groove is controlled, and the size and speed of the irrigation water passing through it are controlled, thereby controlling the irrigation speed of the micro-drip irrigation component.

[0033] (4) By setting up reinforcing ribs and porous fiber cotton inside, the water conveyance function is realized and the strength of the three-dimensional soil stabilization net is improved. The porous fiber cotton is made up of countless fine fibers, forming a huge number of tiny pores, which not only increases the surface area of ​​the material, but also provides abundant channels for water to flow and store, so that the porous fiber cotton can effectively adsorb and store water, air and nutrients.

[0034] (5) Irrigation water is delivered through the water delivery pipe set in the reinforcing rib, and irrigation water is also replenished into the water delivery pipe through the permeation of the water-conducting material, which can prevent the irrigation water from being absorbed in large quantities by the micro-drip irrigation components at the front end.
