[0002] In the arid northwest of my country, Gobi and desert areas are widely distributed. Wind speeds in these areas can reach 20-50 m / s, carrying large amounts of sand. Wind erosion of roadbeds and sand on roads seriously endanger highway facilities and driving safety, making sand control and prevention of desertification particularly important. Traditional methods, such as straw checkerboard sand barriers and clay sand barriers, suffer from problems such as poor material stability and durability, high cost, and complex construction. Nylon mesh sand barriers have weak resistance to ultraviolet radiation and aging, while dense wire mesh and other metal materials have weak corrosion resistance. Under these circumstances, there is an urgent need to develop a new type of sand-blocking material with strong ultraviolet resistance, aging resistance, corrosion resistance, and long service life.

[0003] Traditional sand barrier structures suffer from problems such as unstable structure, easy collapse, frequent maintenance and reinforcement, and easy aging and damage of the barrier material. Therefore, there is an urgent need to design a low-cost, easy-to-install, durable, long-lasting, and easy-to-maintain HDPE board sand barrier for use in the Gobi Desert. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1-6 A sand barrier made of HDPE board for use in Gobi Desert areas includes several spaced columns 2. The bottom of each column 2 is fixedly connected to a column foundation 1, which is buried below the ground. The column foundation 1 is made of a first precast concrete block. The bottom of each column 2 is poured into the interior of the first precast concrete block. A sand barrier board 4 is fixedly installed on the front side of each column 2. The sand barrier board 4 is made of HDPE board.

[0027] HDPE sheets have a smooth and wear-resistant surface, which can resist the abrasion of particles such as sand. Its smooth surface reduces the adhesion of sand particles and reduces the frequency of maintenance.

[0028] HDPE sheets were used as sand barrier panels 4. Compared to traditional materials, HDPE sheets are lightweight (single sheet weight ≤10kg), high-strength (bending strength ≥25MPa), easy to cut and shape, and can be processed according to specific needs, facilitating transportation and installation. HDPE sheets have high mechanical strength, capable of withstanding significant external forces and impacts; they possess excellent weather resistance, maintaining stable performance under extreme climatic conditions (high temperature, low temperature, ultraviolet radiation); and they have good anti-aging properties, resulting in a long service life.

[0029] In this embodiment, the column 2 is provided with a first bolt hole 7, and the sand barrier 4 is fixed to the column 2 by stainless steel bolts, which facilitates installation and disassembly, thereby improving construction efficiency and reducing the cost of later maintenance and replacement.

[0030] In this embodiment, a column brace 3 is fixedly installed on the rear side of the column 2. The top of the column brace 3 is fixedly connected to the column 2 through a fixing structure. A brace foundation 10 is fixedly connected to the bottom of the column brace 3. The brace foundation 10 is buried below the ground. The brace foundation 10 is made of a second precast concrete block. The bottom of the column brace 3 is poured inside the second precast concrete block.

[0031] In this embodiment, both the column foundation 1 and the diagonal brace foundation 10 are made of precast concrete blocks, which can improve on-site construction efficiency by 50%, reduce environmental pollution, and solve the problem of water shortage when using cast-in-place concrete foundations in the Gobi Desert.

[0032] In this embodiment, the fixing structure includes a clamp base 13 and a clamp 12. The clamp base 13 is welded to the top of the column diagonal brace 3. A second bolt hole 11 is provided on the clamp base 13. The clamp 12 is fixedly connected to the clamp base 13 by stainless steel bolts 8. The column 2 is fixed between the clamp 12 and the clamp base 13, and the column diagonal brace 3 and the column 2 form a 45° angle.

[0033] The installation of the column diagonal brace 3 can significantly improve the stability of the sand barrier. During actual installation, the spacing of the column diagonal brace 3 can be flexibly adjusted according to the different wind load intensities in different areas of the Gobi Desert. The column 2 and the column diagonal brace 3 are fixedly connected by the clamp 12, which avoids the problems of easy damage and construction difficulties of the traditional column 2 support. At the same time, it improves the lateral stability of the column 2 and prevents the column 2 from collapsing.

[0034] In this embodiment, a number of steel plate strips 6 are provided on the surface of the sand barrier 4 from top to bottom. The steel plate strips 6 have third bolt holes 5. The steel plate strips 6 are fixed to the sand barrier 4 by stainless steel bolts. At the junction of the steel plate strips 6, the sand barrier 4 and the column 2, the stainless steel bolts pass through the three in sequence to fix them together, thereby improving the overall stability of the sand barrier. The setting of the steel plate strips 6 can prevent the sand barrier 4 from undergoing large deformation under wind load.

[0035] In this embodiment, the column 2 is made of stainless steel pipe, which can reduce weight and cost while ensuring service life. The top of the column 2 is equipped with a column cap 9 to prevent sand and rainwater from entering the column.

[0036] In this embodiment, the facade of the sand barrier 4 is a flat or wavy surface. When wind and sand pass through the sand barrier 4, the front and rear flow field structures will be significantly adjusted, forcing the change of airflow movement state, resulting in a change in sand carrying capacity, and realizing the sedimentation and accumulation of sand. The sand barrier 4 forms a continuous barrier through modular splicing, thereby achieving the effect of windbreak and sand fixation.

[0037] In this embodiment, a plurality of air passage holes are evenly distributed on the sand barrier 4, and the total area of ​​the air passage holes accounts for 30%-50% of the total area of ​​the sand barrier 4. This can reduce wind pressure resistance and effectively intercept sand particles. The air passage holes can be set as rectangles, triangles or trapezoids.

[0038] HDPE boards are manufactured with anti-UV aging agents to effectively cope with the strong sunlight and ultraviolet radiation in the Gobi Desert and reduce the UV aging of the boards.

[0039] A green colorant is added during the manufacturing process of HDPE boards, resulting in a green screen that enhances the visual experience.

[0040] Plant fibers (such as corn stalk fiber and cotton stalk fiber) can be added during the manufacturing process of HDPE boards to enhance the toughness of the HDPE board, while also increasing the utilization rate of waste cotton stalks and corn stalks and reducing carbon emissions.

[0041] HDPE sheets have outstanding low-temperature resistance, maintaining good toughness even at -40℃, unlike hard plastics (such as PVC) which become brittle and crack, making them suitable for use in cold Gobi desert regions.

[0042] HDPE boards have strong resistance to environmental aging and can be used in outdoor environments such as the Gobi Desert. Their performance degrades slowly when exposed to sunlight for a long time, resulting in a long service life and reducing replacement frequency and costs.

[0043] HDPE boards have a smooth and uniform surface, making them easy to cut during processing. They require no complex equipment, resulting in high processing efficiency and low processing costs.

[0044] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
