Description

Technical Field

[0001] This invention relates to the field of environmental governance technology, and more specifically, to a method for manufacturing a grid protection belt for sand fixation in salt lake brine, a construction method for a sand fixation protection system, and a road sand fixation protection system. Background Technology

[0002] Due to low rainfall and high evaporation, arid regions have unique wind-blown sand landforms, which have also led to the formation of many salt lakes. Wind-blown sand disasters cause great harm to the industrial and agricultural development of arid regions, seriously affecting their sustainable development. While arid regions have a large number of salt lakes, their main function is to process and enhance various salt minerals, but there are no reports of them being used as raw materials for sand fixation.

[0003] The inventors discovered the following drawbacks in existing sand-fixing and protection systems:

[0004] Traditional sand-fixing methods, such as straw checkerboard, polyethylene sand-fixing net, and high-density polyethylene sand-fixing net, are easily corroded near salt lakes and in saline-alkali areas, resulting in a very short service life and unsatisfactory sand-fixing effect. Summary of the Invention

[0005] The purpose of this invention is to provide a method for manufacturing a sand-fixing grid protection belt for salt lake brine, a construction method for a sand-fixing protection system, and a road sand-fixing protection system. These methods can utilize salt lake brine for sand prevention and fixation in a way that is suitable for local conditions, with good results, environmental protection, and cost reduction.

[0006] The embodiments of the present invention are implemented as follows:

[0007] In a first aspect, the present invention provides a method for manufacturing a mesh protective belt for sand fixation in salt lake brine, comprising:

[0008] The brine and sand are mixed in a weight ratio of 1:5 to 1:8 to make the first brine slurry;

[0009] A sand-fixing molding mold with a pouring space is formed by splicing together multiple sand-fixing plates with storage holes.

[0010] The first brine mortar is poured into the pouring space, and the brine mortar fills the pouring space and the receiving hole;

[0011] Demolding is performed to obtain brine-fixed sand boards filled with the first brine mortar. Multiple brine-fixed sand boards are then spliced ​​together to form a sand-fixed grid protective belt.

[0012] In an optional embodiment, in the step of mixing brine and sand in a weight ratio of 1:5 to 1:8 to prepare a first brine slurry, the sand is first poured into a mixer, and then the brine is poured into the mixer, and the mixer is used to mix them.

[0013] In an optional embodiment, after the step of demolding to obtain the brine-based sand-fixing board filled with the first brine slurry and before the step of splicing multiple brine-based sand-fixing boards to form a sand-fixing protective belt, the following step is also included: laying the brine-based sand-fixing board flat and drying it for at least 24 hours.

[0014] Secondly, the present invention provides a construction method for a sand-fixing and protection system, the construction method comprising:

[0015] The method for manufacturing a sand-fixing mesh protection belt for salt lake brine as described in any of the foregoing embodiments.

[0016] In an optional implementation, the construction method further includes:

[0017] Construct a protective belt for sand fixation on the surface of salt lake brine, a protective belt for halophytes, and a protective belt for sand fixation in the body of salt lake brine. The protective belt for sand fixation on the grid, the protective belt for sand fixation on the surface, the protective belt for halophytes, and the protective belt for sand fixation in the body of salt lake brine are arranged in sequence, and the protective belt for sand fixation in the body of salt lake brine is located on one side of the roadbed width direction.

[0018] In an optional implementation, the step of constructing a protective belt for sand stabilization on the brine surface of a salt lake includes:

[0019] The brine and sand are mixed in a weight ratio of 1:3 to 1:6 to make a second brine slurry;

[0020] The second brine slurry is sprayed onto the surface of the area to be stabilized and treated, forming a brine slurry sand-stabilizing surface.

[0021] In an optional implementation, the step of constructing the halophyte protective strip includes:

[0022] Halophytes are planted on the ground surface. The halophytes include trees, shrubs and herbaceous plants, wherein the trees and shrubs are planted in rows and columns, and the herbaceous plants are planted by surface sowing.

[0023] In an optional implementation, the step of constructing a protective belt for sand stabilization in salt lake brine includes:

[0024] Multiple layers of brine mortar are sprayed from bottom to top to form a multi-layer brine mortar layer. The cross-sectional profile of the multi-layer brine mortar layer gradually decreases from bottom to top to form a sand-fixing body with a triangular longitudinal profile. Multiple sand-fixing bodies are arranged in an intersecting pattern to form a grid structure.

[0025] In an optional implementation, the construction method further includes:

[0026] On each side of the roadbed width, a protective belt for sand fixation by salt lake brine, a protective belt for halophytes, a protective belt for sand fixation by salt lake brine surface, and a protective belt for sand fixation by salt lake brine grid are constructed in sequence.

[0027] Thirdly, the present invention provides a road sand-fixing protection system based on the construction method of the sand-fixing protection system described in any of the foregoing embodiments, the road sand-fixing protection system comprising:

[0028] The roadbed is arranged in sequence along the width direction of the following: a grid protection belt for sand fixation by salt lake brine, a surface protection belt for sand fixation by salt lake brine, a protection belt for halophyte plants, and a protection belt for sand fixation by salt lake brine. The protection belt for sand fixation by salt lake brine is located close to the roadbed.

[0029] The beneficial effects of the embodiments of the present invention are:

[0030] In summary, this embodiment provides a method for manufacturing a brine-based sand-fixing mesh protective belt. Salt lakes are abundant in arid regions, and brine is plentiful near these lakes and in saline-alkali areas. Therefore, locally sourced materials can be utilized, including brine from salt lakes and aeolian sand from wind-blown sandy areas. The brine and sand are mixed in a predetermined ratio to obtain a first brine slurry, a method that is both adaptable to local conditions and cost-effective. Furthermore, the first brine slurry is combined with a mold, filling the receiving holes in the sand-fixing plate that forms the mold. After the first brine slurry and sand-fixing plate are bonded, the mold is demolded to obtain the brine-fixed sand-fixing plate. Because the combination of brine and sand forms a salt crust and salt film with extremely high hardness and strong wind erosion resistance, the combination of the first brine slurry and the sand-fixing plate effectively enhances the structural strength of the sand-fixing plate, resulting in strong corrosion and wind erosion resistance, a long service life, and resistance to damage. At the same time, multiple brine sand-fixing boards are used together to form a sand-fixing grid protection belt. The sand-fixing grid protection belt can effectively reduce the surface wind speed, suppress the local sand blowing, and block the wind and sand flow, playing a highly efficient sand-blocking role and having a good protective effect.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] Currently, arid regions, due to low rainfall and high evaporation, exhibit unique aeolian landforms and have also formed numerous salt lakes. The brine in these salt lakes is highly corrosive. Traditional sand-fixing methods, such as straw checkerboards, polyethylene sand-fixing nets, and high-density polyethylene sand-fixing nets, are easily corroded near salt lakes and in saline-alkali areas, resulting in extremely short service lives and unsatisfactory sand-fixing effects. The inventors discovered in practice that although salt lake brine is highly corrosive, it contains various minerals and has a strong adhesive bond with sand particles, forming a strong solidified material with excellent wind erosion resistance. Salt lakes are generally not far from aeolian areas, making them highly usable. Furthermore, salt lakes also face severe wind and sand disasters. If salt lake brine can be utilized directly and locally, it will achieve low-cost sand fixation and improve sand-fixing protection effectiveness.

[0046] In view of this, the designers have provided a method for manufacturing a salt lake brine sand-fixing mesh protection belt 001, which can utilize salt lake brine for sand fixation in a way that is suitable for local conditions, with good results, environmental protection and cost reduction.

[0047] Please combine Figures 1-3 In this embodiment, the manufacturing method of the salt lake brine sand-fixing mesh protection belt 001 includes the following steps:

[0048] Step s100: Mix brine and sand in a weight ratio of 1:5 to 1:8 to prepare a first brine slurry. For example, the brine and sand can be mixed in a weight ratio of 1:5, 1:6.5, or 1:8. When the brine and sand are combined in the set ratio, a salt crust and salt film will form, exhibiting extremely high hardness and strong resistance to wind erosion. During operation, the prepared sand can be poured into a mixer first, followed by the prepared brine. The mixer is then started to stir and mix the mixture, improving its tightness. The mixing time should be no less than 5 minutes. After the set mixing time, the first brine slurry is obtained.

[0049] It should be noted that the brine can be taken from salt lakes, and the sand can be taken from wind-blown sand in windy and sandy areas.

[0050] Step s200: Prepare the sand-fixing molding mold 100. Specifically, multiple sand-fixing plates 110 with receiving holes 111 are spliced ​​together to form a sand-fixing molding mold 100 with a pouring space 130. Each sand-fixing plate 110 can be a rectangular plate, and the receiving holes 111 can be round, square, etc. The receiving holes 111 penetrate through both surfaces of the sand-fixing plate 110, that is, the receiving holes 111 are through holes. It should be understood that there can be multiple receiving holes 111 on the sand-fixing plate 110. The multiple receiving holes 111 are arranged in a rectangular array. The multiple receiving holes 111 are arranged reasonably, effectively utilizing the area of ​​the sand-fixing plate 110, so that the sand-fixing plate 110 can better bond with the first brine mortar. Meanwhile, multiple sand-fixing plates 110 can be arranged in a crisscross pattern, with four sand-fixing plates 110 forming a square casting space 130. The sand-fixing molding mold 100 has multiple casting spaces 130, and adjacent casting spaces 130 share a sand-fixing plate 110. Thus, the intersection of the four sand-fixing plates 110 forms a cross structure. A locking cap 120 can be placed at each intersection position. The locking cap 120 has a cross-shaped groove 121. The edges of the four sand-fixing plates 110 forming the same cross structure are all locked in the cross-shaped groove 121. In this way, the locking cap 120 can improve the firmness of the connection structure of the multiple sand-fixing plates 110. When the first brine mortar is poured into the casting space 130, the sand-fixing molding mold 100 is not prone to deformation. The first brine mortar can fill the casting space 130 as much as possible and fill the receiving hole 111, so that the first brine mortar and the receiving hole 111 are tightly bonded.

[0051] In one possible implementation, the sand-stabilizing plate 110 is a cuboid plate with a length of 1.0-1.5m, a height of 15-25cm, and a thickness of 4-7cm. The sand-stabilizing plate 110 has evenly distributed circular holes 111 with a diameter of 1.5-2.0cm. The outer circumference spacing of the holes 111 is 2.5-3.5cm, meaning the minimum distance between the edges of adjacent holes 111 is 2.5-3.5cm. Meanwhile, the lock cap 120 is a cylinder with a height of 10-15cm. The top is a solid cylinder with a diameter of 15-20cm and a height of 5-7cm. The bottom surface has two slots 121 arranged in a cross shape, each slot 121 with a width of 4-7cm. It should be understood that the structural dimensions of the sand-stabilizing plate 110 and the lock cap 120 can also be other parameters, which will not be described in detail in this embodiment.

[0052] Step s300: Demolding to obtain brine-fixed sand slabs 110 filled with the first brine mortar. Multiple brine-fixed sand slabs 110 are spliced ​​together to form a sand-fixed mesh protective belt. That is, after the first brine mortar fills the casting space 130, it enters and fills the receiving holes 111. After demolding, the sand slabs 110 are separated from the first brine mortar formed in the casting space 130, resulting in brine-fixed sand slabs 110 with the receiving holes 111 filled with the first brine mortar. All receiving holes 111 of each brine-fixed sand slab 110 are filled with the first brine mortar, giving the brine-fixed sand slab 110 high structural strength and strong resistance to corrosion and wind erosion. Before demolding, the locking caps 120 can be pulled away from the sand slabs 110 for easier demolding. After demolding, obtain multiple brine-based sand-fixing boards 110. Lay each board flat and allow it to dry for at least 24 hours to ensure a stronger bond between the first brine mortar and the board. During drying, the boards can be flipped as needed to expose both sides. Once dried, the boards are joined together to form a sand-fixing mesh protective strip. It should be noted that the boards can be arranged in a crisscross pattern, and one side of the cross-shaped arrangement of four boards can be secured with locking caps 120 to improve overall structural strength.

[0053] Optionally, magnesium cement can be added appropriately during the preparation of the first brine mortar, wherein the weight ratio of magnesium cement to sand is between 4:1 and 5:1. Adding magnesium cement can significantly improve the strength and cohesion of the prepared first brine mortar, thereby enhancing its resistance to wind erosion. Furthermore, the magnesium cement used in this embodiment can be a product extracted from salt lake brine, reducing costs.

[0054] Optionally, in other embodiments, when preparing the first brine slurry, an appropriate amount of *Reed Catkins* straw is added to the raw materials to form a mixture, which can significantly improve the cohesiveness of the brine slurry. Furthermore, *Reed Catkins* is a common plant in arid regions, suitable for local collection, and convenient to use. The amount of *Reed Catkins* straw is selected as needed, and this embodiment does not impose a specific limitation. In addition, when adding *Reed Catkins* straw, its length can be cut to 5-10 cm first, and then it can be crushed and dried to obtain dry straw fragments.

[0055] In another embodiment, when the brine-based sand-stabilizing board 110 is obtained through demolding, a layer of hemp rope fiber mesh is applied to the windward side of the board to further increase its structural strength. The windward side of the brine-based sand-stabilizing board 110 is the side facing the prevailing wind direction.

[0056] The method for manufacturing the salt lake brine sand-fixing mesh protective belt 001 provided in this embodiment utilizes locally sourced materials. It mixes the brine from the salt lake and aeolian sand particles from wind-blown sandy areas in a predetermined ratio to obtain a first brine slurry. This method is locally adapted and cost-effective. The first brine slurry is then combined with a mold, filling the receiving holes 111 on the sand-fixing plate 110 that forms the mold. After the first brine slurry and sand-fixing plate 110 are combined, the mold is demolded to obtain the brine sand-fixing plate 110. A hemp rope fiber mesh is installed on the windward side of the brine sand-fixing plate 110. Because the combination of brine and sand particles forms a salt crust and salt film with extremely high hardness and strong wind erosion resistance, the combination of the first brine slurry and the sand-fixing plate 110 effectively enhances the structural strength of the sand-fixing plate 110, resulting in strong corrosion and wind erosion resistance, a long service life, and resistance to damage. Meanwhile, multiple brine sand-fixing boards 110 are used together to form a sand-fixing grid protection belt. The sand-fixing grid protection belt can effectively reduce the surface wind speed, suppress local sand blowing, and block wind and sand flow, playing a highly efficient sand-blocking role and having a good protective effect.

[0057] This embodiment also provides a construction method for a sand-fixing protection system, used to install sand-fixing protection systems on both sides of roadbed 005. Specifically, sand-fixing protection systems are installed on both sides of the roadbed 005 in the width direction; this embodiment uses the sand-fixing protection system on one side of the roadbed 005 as an example for illustration.

[0058] The construction method for this sand-fixing and protection system includes:

[0059] Please combine Figure 4 and Figure 5According to the manufacturing method provided in the above embodiments, a salt lake brine sand fixation grid protection belt 001 is constructed. On the side of the salt lake brine sand fixation grid protection belt 001 near the roadbed 005, a salt lake brine sand fixation surface protection belt 002, a halophyte protection belt 003, and a salt lake brine sand fixation body protection belt 004 are constructed in sequence. The salt lake brine sand fixation body protection belt 004 is set close to the roadbed 005 and can be connected to the roadbed 005.

[0060] In the construction of the brine-based sand-fixing protective belt 002, brine and sand are mixed at a weight ratio of 1:3 to 1:6 to create a second brine slurry. This second brine slurry is then sprayed onto the surface of the area to be stabilized and treated, forming a brine-slurry sand-fixing surface. It should be understood that both the brine and sand used in the second brine slurry can be sourced locally, reducing costs.

[0061] Alternatively, the construction method for the halophyte protective strip 003 is as follows:

[0062] The halophyte protective belt 003 is located on the side of the brine-stabilized sand protection belt 002 adjacent to the roadbed 005. The width of the covered area of ​​the halophyte protective belt 003 is 8-10m, and this width direction is consistent with the width direction of the roadbed 005. The halophyte protective belt 003 includes trees, shrubs, and herbaceous plants. Trees and shrubs are planted in rows, while herbaceous plants are sown in the field. Specifically, trees and shrubs include poplar, tamarisk, and jujube, while herbaceous plants include Suaeda salsa, reeds, Dunaliella salina, Salix babylonica, Salix babylonica, Salix babylonica, Salix babylonica, and Salix babylonica.

[0063] Optionally, the construction method for the 004 protective belt for sand stabilization in salt lake brine is as follows:

[0064] A brine-based sand-fixing protection zone 004 is constructed on the side of the halophyte protection zone 003 closest to the roadbed 005. The brine-based sand-fixing protection zone 004 is 10-15m wide and 15-20cm high, and is arranged in a grid pattern, with each grid consisting of square cells with sides of 1.0-1.5m. It should be understood that the brine-based sand-fixing protection zone 004 can also be formed by spraying brine slurry. It should be noted that during the construction of the brine-based sand-fixing protection zone 004, sand-fixing bodies are set on the surface of the sand to be protected. These sand-fixing bodies are strip-shaped and formed by spraying multiple layers of brine mortar. Each sand-fixing body consists of multiple layers of brine mortar layered from bottom to top, with each layer stacked on top of the others. During the formation of the brine mortar layers, the cross-sectional area of ​​each layer gradually decreases from bottom to top; that is, the cross-sectional area of ​​the lower layer is larger than that of the upper layer. This ultimately forms a sand-fixing body with a triangular longitudinal cross-section. Multiple sand-fixing bodies are arranged crisscrossingly to form a grid-like brine-based sand-fixing protection zone 004. Each grid can be formed by four sand-fixing bodies surrounding it. Each grid can be a square or rectangle with a side length of 1.0-1.5m and a height of 15-20cm. By setting up a grid-like protective belt for sand fixation in the salt lake brine, surface wind speed can be effectively reduced, local sand blowing can be suppressed, and wind and sand flow can be blocked, thus playing a highly efficient role in sand control.

[0065] The sand fixation and protection system construction method provided in this embodiment involves setting up a salt lake brine sand fixation grid protection belt 001, a salt lake brine sand fixation surface protection belt 002, a halophyte protection belt 003, and a salt lake brine sand fixation body protection belt 004 on both sides of the roadbed 005. The salt lake brine sand fixation body protection belt 004 is set close to the roadbed 005, thus achieving a good sand fixation and protection effect on the roadbed 005.

[0066] Please combine Figure 4 and Figure 5 This embodiment also provides a road sand-fixing and protection system, suitable for wind and sand control projects on railways, highways, and other roads near salt lakes and in saline-alkali areas. This road sand-fixing and protection system is constructed based on the aforementioned sand-fixing and protection system construction method, and includes a salt lake brine sand-fixing grid protection belt 001, a salt lake brine sand-fixing surface protection belt 002, a halophyte protection belt 003, and a salt lake brine sand-fixing body protection belt 004 arranged sequentially along the width of the roadbed 005. The salt lake brine sand-fixing body protection belt 004 is positioned close to the roadbed 005. The protection system is installed on both sides of the roadbed 005, greatly improving the sand-fixing and protection effect.

[0067] The sand fixation and protection system construction method and road sand fixation and protection system provided in this embodiment have at least the following advantages:

[0068] 1. There are large amounts of salt lake brine distributed near salt lakes and in saline-alkali areas. Utilizing salt lake brine for sand prevention and fixation in accordance with local conditions is innovative and practical.

[0069] 2. In this embodiment, brine and sand particles combine to form a salt crust and salt film, which have extremely high hardness and strong resistance to wind erosion.

[0070] 3. In areas near salt lakes and saline-alkali regions, brine is abundant and highly salinized, making it extremely corrosive. Traditional sand-fixing measures, such as straw checkerboards, polyethylene sand-fixing nets, and high-density polyethylene sand-fixing nets, are easily corroded in these areas, resulting in a very short service life and unsatisfactory sand-fixing effects. The road sand-fixing and protection system provided in this embodiment can effectively improve the situation of short service life and high cost of existing sand-fixing measures.

[0071] 4. The road sand stabilization and protection system provided in this embodiment is characterized by the use of natural materials, which is environmentally friendly. The materials come from nature and ultimately return to nature, making it green and environmentally friendly.

[0072] 5. The sand fixation method, sand fixation materials, and windbreak and sand fixation system provided in this embodiment propose the idea of ​​using salt to control sand, which is advanced.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
