[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0036] like Figures 1 to 4 As shown, this embodiment provides a wind-proof and sand-fixing grid system, including a fixing component and a plurality of wind-proof and sand-fixing grids 1, each wind-proof and sand-fixing grid 1 includes a plurality of small grids 11 spliced in sequence, and each small grid 11 is surrounded by a protective belt 111. The wind-proof and sand-fixing grid 1 is quadrilateral, and the wind-proof and sand-fixing grid 1 is provided with fixing holes 12. The fixing component includes a cross nail 2, a U-shaped nail 3 and a 1-shaped nail 4. A plurality of wind-proof and sand-fixing grids 1 are spliced in sequence, and the intersection of more than three fixing holes 12 is fixed with a cross nail 2, the intersection of two fixing holes 12 is fixed with a U-shaped nail 3, and one fixing hole 12 is fixed with a 1-shaped nail 4. The cross nail 2, the U-shaped nail 3 and the 1-shaped nail 4 all pass through the corresponding fixing holes 12 and are inserted below the sand ground. Each wind-proof and sand-fixing grid 1 is detachable. When the wind-proof and sand-fixing grid system is installed, the wind-proof and sand-fixing grids 1 are installed and spliced one by one. In the later operation and maintenance stage, when a certain wind-proof and sand-fixing grid 1 is damaged, it can be disassembled and replaced individually. The assembly is simple and convenient, and the later operation and maintenance are convenient. In addition, after the installation of the wind-proof and sand-fixing grid system is completed, after a period of sedimentation, the sand in the wind-proof and sand-fixing grid 1 accumulates to a certain height, and the wind-proof and sand-fixing effect is reduced. The fixing components can be pulled out and the position height of the protective belt 111 can be adjusted so that the effective protection height of the wind-proof and sand-fixing grid 1 returns to the initial height. Alternatively, after the mobile sand dunes are converted into fixed sand dunes, the wind-proof and sand-fixing grid 1 here can also be moved to other locations for reuse.
[0037] Specifically, when installing the wind-proof and sand-fixing grid system, first lay out the lines to clarify the position of each wind-proof and sand-fixing grid 1; then start the installation from the upwind position, and lay multiple wind-proof and sand-fixing grids 1 flat in the line-laying and positioning positions in turn; then select the corresponding fixing components according to the number of fixing holes 12 at the junction, and gradually extend them downward in rows through splicing and assembly until the installation of the entire wind-proof and sand-fixing grid system is completed.
[0038] If an error occurs during installation, resulting in the width of the last column not being consistent with the designed width of the windbreak and sand fixation grid 1, the shape of the windbreak and sand fixation grid 1 can be adjusted to a diamond shape to meet the width requirement. Alternatively, if the site is irregular, the shape of the windbreak and sand fixation grid 1 can be customized in advance to fit the site shape.
[0039] Optionally, the windbreak and sand fixation grid 1 is quadrilateral, and the quadrilateral setting can be beneficial to improving the sand fixation effect. Figure 1 , the windbreak and sand fixation grid 1 can be square, and accordingly, the small grid 11 is also square; or, referring to Figure 2 The windbreak and sand fixation grid 1 may also be a parallelogram, and correspondingly, the small grid 11 may also be a parallelogram; or, in other embodiments, the windbreak and sand fixation grid 1 may also be a rectangle or a quadrilateral of other shapes.
[0040] Specifically, the junctions of the plurality of small grids 11 can be fixed with cross nails 2 , U-shaped nails 3 or I-shaped nails 4 , as long as the plurality of small grids 11 can be spliced into the windbreak and sand fixation grid 1 .
[0041] Optionally, the protective belt 111 is made of high-density polyethylene material, so that the protective belt 111 has good anti-oxidation and anti-weathering properties, thereby effectively extending the service life of the windbreak and sand fixation grid system.
[0042] Optionally, the side length of the small grid 11 is 1m-2m. Specifically, in this embodiment, the side length of the small grid 11 is 1m, which not only protects the psammophytes from being buried by wind erosion and sand, but also prevents local sand blowing, thereby having a good sand fixation effect.
[0043] Optionally, the small grid 11 is 0.2m-0.5m high. Based on the physical principle of parabolic motion of sand particles, this height range is sufficient to block wind and sand, and allow the wind to form a rotational motion within the grid, forming a pot-shaped body with high edges and a low center, which is conducive to improving the sand fixation effect.
[0044] Optionally, refer to Figures 3 to 5 The ends of the cross nails 2, U-shaped nails 3 and I-shaped nails 4 inserted into the ground are all provided with pointed ends, so that the cross nails 2, U-shaped nails 3 and I-shaped nails 4 can be smoothly inserted under the sandy ground, which is conducive to improving installation efficiency.
[0045] Optionally, the ends of the cross nails 2, U-shaped nails 3 and I-shaped nails 4 away from the ground are all provided with an operating portion (not shown in the figure) to facilitate the operation of the operator. Specifically, the operating portion is an operating handle.
[0046] Furthermore, the operating unit is provided with an anti-slip structure. Specifically, the anti-slip structure is a non-slip pad, such as a rubber pad, provided on the outside of the operating unit; alternatively, the anti-slip structure is provided with anti-slip protrusions on the outside of the operating unit. The anti-slip protrusions can be dot-shaped protrusions or patterned protrusions of any shape. Their function is to increase the contact friction between the operating unit and the operator's hand, facilitating operation. The specific form of the anti-slip structure is referenced in the prior art and is not specifically limited in this embodiment; any anti-slip structure is sufficient as long as it can increase friction.
[0047] Optionally, the cross nails 2, U-shaped nails 3 and I-shaped nails 4 are all made of alloy materials, which have the advantages of high hardness and high corrosion resistance, and can effectively improve the service life of the windbreak and sand fixation grid system.
[0048] Optionally, the protective belt 111 is provided with a plurality of mesh holes, which are arranged in a dot matrix. Specifically, the mesh holes can be circular, diamond-shaped, or rectangular. The arrangement of the mesh holes can effectively reduce wind speed on the slope surface and improve sand fixation.
[0049] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
