Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway sand control technology, specifically a sand control structure for desert highways. Background Technology
[0002] In desert regions, frequent and prolonged sandstorms during spring and autumn cause shifting sand to accumulate on roads, posing significant safety hazards to road operations. Currently, traditional sweepers are used to remove sand from roads, which, while more efficient than manual cleaning, cannot fundamentally solve the problem of shifting sand on roads and requires frequent cleaning, consuming substantial manpower, resources, and funds. Therefore, it is necessary to install sand-prevention structures along roadsides.
[0003] In existing technologies, although dense mesh grids can play a certain role in blocking sand, they are mostly made of plastic, which is difficult to degrade and easily causes environmental pollution. They are also prone to aging and damage under strong ultraviolet rays and long-term wind and sand erosion, requiring frequent replacement and high maintenance costs. Wood grids are easily eroded and deformed under continuous wind and sand impact, resulting in a gradual decrease in sand prevention effect. At the same time, their installation and maintenance require a lot of manpower and material resources. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a sand-proof structure for desert highways, which solves the problem that existing technologies are easily eroded and deformed under continuous wind and sand impact, leading to a gradual decrease in sand-proof effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand-proof structure for desert highways, comprising concrete columns, with foundation piles fixedly connected to the bottom of the concrete columns, and further comprising: a fixing ring, the fixing ring being threadedly connected to a pre-embedded threaded sleeve in the concrete column, a steel wire rope being fixedly connected to the outside of the fixing ring, a binding strap being fixedly connected to the outside of the steel wire rope, and a straw mat being fixedly connected to the outside of the binding strap, a limiting component being fixedly connected to the outside of the concrete column, the limiting component being used to restrict the rotation of the fixing ring, the fixing ring having an external thread corresponding to the internal thread of the pre-embedded threaded sleeve, and being fixed to the concrete column by screwing into the pre-embedded threaded sleeve, with the insertion hole 5 of the fixing ring 4 facing upward after tightening, multiple steel wire ropes being arranged between adjacent concrete columns, with both ends tied to the concrete columns by the fixing rings to provide good support for the straw mat.
[0006] Preferably, the fixing rings are arranged linearly along the central axis of the concrete column, and the binding straps are arranged linearly along the outer side of the wire rope. The straw curtain is fixed to the bound wire rope by the binding straps.
[0007] Preferably, the limiting component includes a fixed plate, a limiting slide rod is slidably connected to the inner wall of the fixed plate, a connecting frame is fixedly connected to the outer wall of the limiting slide rod, and an insert rod is fixedly connected to the outer side of the connecting frame. Pushing the connecting frame can cause the limiting slide rod to slide along the inner wall of the fixed plate.
[0008] Preferably, the outer wall of the limiting slide rod is fixedly connected to a limiting block, and the limiting block is linearly arranged along the central axis of the limiting slide rod. The outer side of the fixing plate is fixedly connected to the outer wall of the concrete column, and the fixing plate is fixed to the outer wall of the concrete column by bolts, providing a sliding track for the limiting slide rod.
[0009] Preferably, the bottom end of the insertion rod is inserted into the inner wall of the fixing ring through an insertion hole, and the insertion hole is opened in the wall of the fixing ring. Inserting the insertion rod into the insertion hole of the fixing ring can restrict the rotation of the fixing ring.
[0010] The beneficial effects of this utility model are as follows:
[0011] (i) The structure provides support for the straw curtain by setting steel wire ropes. The straw curtain is made of waste straw, reeds and other materials, which are easy to degrade and inexpensive. When wind and sand come, they first come into contact with the straw curtain. Because the material itself has a certain degree of porosity, it can reduce the wind speed and allow some air to pass through, reducing the impact of the wind on the structure. While extending the service life of the structure, it also causes some sand to settle in front of the straw curtain, which can effectively prevent the sand from moving towards the road and avoid the sand from accumulating on the road. This not only reduces the need for repeated cleaning of the road surface where sand frequently accumulates, but also greatly reduces the safety hazard factor of passing vehicles caused by sand accumulation on the road surface, and improves driving comfort and safety.
[0012] (ii) The structure prevents the fixed ring from loosening due to wind and sand vibration by setting a limiting component. The fixed plate is fixed to the outer wall of the concrete column by bolts, providing a sliding track for the limiting slide rod. Pushing the connecting frame can make the limiting slide rod slide along the inner wall of the fixed plate, driving the insertion rod to insert into the insertion hole of the fixed ring. This can limit the rotation of the fixed ring, thereby preventing the fixed ring from loosening due to wind and sand vibration, enhancing the stability of the structure, and also making the fixed ring easy to replace, thereby reducing the maintenance cost of the structure.

[0018] 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.
[0019] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a sand-proof structure for desert highways, including concrete columns 1, with foundation piles 2 fixedly connected to the bottom of the concrete columns 1, and also including: a fixing ring 4, which is threadedly connected to a pre-embedded threaded sleeve 3 in the concrete columns 1; a steel wire rope 6 is fixedly connected to the outside of the fixing ring 4; a binding strap 9 is fixedly connected to the outside of the steel wire rope 6; a straw mat 8 is fixedly connected to the outside of the binding strap 9; a limiting component 7 is fixedly connected to the outside of the concrete columns 1 to limit the rotation of the fixing ring 4; the fixing ring 4 is linearly arranged along the central axis of the concrete columns 1; and the binding straps 9 are linearly arranged along the outside of the steel wire rope 6. During installation, the concrete columns 1 are placed on both sides of the highway, with the concrete columns 1 serving as the core support component. The foundation piles 2 at their bottom are embedded 1.5 meters below the ground, and the distance between adjacent concrete columns 1 is 2.5 meters. The fixing ring 4 has a threaded sleeve that connects to the pre-embedded threaded sleeve. The internal thread corresponds to the external thread, which is fixed to the concrete column 1 by screwing into the pre-embedded threaded sleeve 3. After tightening, the insertion hole 5 of the fixing ring 4 faces upward. Multiple steel wire ropes 6 are set between adjacent concrete columns 1, and their two ends are tied to the concrete column 1 by the fixing ring 4, providing good support for the straw curtain 8. The straw curtain 8 is fixed to the tied steel wire ropes 6 by the binding strap 9. The straw curtain 8 is composed of waste straw, reeds and other materials. When the wind and sand come, they first come into contact with the straw curtain 8. Because the material itself has a certain porosity, it can reduce the wind speed and allow some air to pass through, reducing the impact of the wind on the structure. At the same time, it can cause some sand to settle in front of the straw curtain 8, which can effectively prevent the sand from moving towards the road and avoid the sand from accumulating on the road. This not only reduces the need for repeated cleaning of the road surface where sand frequently accumulates, but also greatly reduces the safety hazard coefficient of passing vehicles caused by sand accumulation on the road surface, and improves driving comfort and safety.
[0020] The limiting component 7 includes a fixing plate 71. A limiting slide rod 72 is slidably connected to the inner wall of the fixing plate 71. A connecting frame 73 is fixedly connected to the outer wall of the limiting slide rod 72. An insert rod 74 is fixedly connected to the outer side of the connecting frame 73. A limiting block 75 is fixedly connected to the outer wall of the limiting slide rod 72, and the limiting block 75 is linearly arranged along the central axis of the limiting slide rod 72. The outer side of the fixing plate 71 is fixedly connected to the outer wall of the concrete column 1. The bottom end of the insert rod 74 is inserted into the inner wall of the fixing ring 4 through an insertion hole 5, and the insertion hole 5 is opened in the wall of the fixing ring 4. The limiting component 7 is used to prevent... To prevent the fixed ring 4 from loosening due to wind and sand vibration, the fixed plate 71 is fixed to the outer wall of the concrete column 1 with bolts, providing a sliding track for the limiting slide rod 72. Pushing the connecting frame 73 allows the limiting slide rod 72 to slide along the inner wall of the fixed plate 71, driving the insertion rod 74 to be inserted into the insertion hole 5 of the fixed ring 4. This restricts the rotation of the fixed ring 4, thereby preventing the fixed ring 4 from loosening due to wind and sand vibration and enhancing the structural stability. The limiting block 75 is arranged along the axis of the limiting slide rod 72, which can prevent the limiting slide rod 72 from sliding excessively and causing the limiting slide rod 72 to detach from the fixed plate 71.
[0021] Working principle: During the installation of the structure, concrete columns 1 are placed on both sides of the road. Concrete columns 1 serve as the core support components. The foundation piles 2 at the bottom of the concrete columns 1 are buried 1.5 meters below the ground. The spacing between adjacent concrete columns 1 is 2.5 meters. The fixing ring 4 has an external thread corresponding to the internal thread of the pre-embedded threaded sleeve 3. It is fixed to the concrete column 1 by screwing into the pre-embedded threaded sleeve 3. After tightening, the insertion hole 5 of the fixing ring 4 faces upward. Multiple steel wire ropes 6 are set between adjacent concrete columns 1. Their two ends are tied to the concrete column 1 by the fixing rings 4 to provide good support for the straw curtain 8. The straw curtain 8 is fixed to the tied steel wire ropes 6 by the binding straps 9.
[0022] Among them, the straw curtain 8 is made of waste straw, reeds and other materials. When the wind and sand come, they first come into contact with the straw curtain 8. Because the material itself has a certain pores, it can reduce the wind speed and allow some air to pass through, reducing the impact of the wind on the structure. At the same time, it causes some sand to settle in front of the straw curtain 8, which can effectively prevent the sand from moving towards the road and avoid the sand from accumulating on the road. This not only reduces the need for repeated cleaning of the road surface where sand frequently accumulates, but also greatly reduces the safety hazard factor of passing vehicles caused by sand accumulation on the road surface, and improves driving comfort and safety.
[0023] The limiting component 7 is used to prevent the fixed ring 4 from loosening due to wind and sand vibration. The fixing plate 71 is fixed to the outer wall of the concrete column 1 by bolts, providing a sliding track for the limiting slide rod 72. Pushing the connecting frame 73 can make the limiting slide rod 72 slide along the inner wall of the fixing plate 71, driving the insertion rod 74 to be inserted into the insertion hole 5 of the fixed ring 4. This can limit the rotation of the fixed ring 4, thereby preventing the fixed ring 4 from loosening due to wind and sand vibration and enhancing the structural stability. The limiting block 75 is arranged along the axis of the limiting slide rod 72, which can prevent the limiting slide rod 72 from sliding excessively and causing the limiting slide rod 72 to detach from the fixing plate 71.
