[0001] This application relates to the field of railway technology, and in particular to a design method, device, equipment and medium for railway sand control belts in degraded grassland areas. Background Technology
[0002] Many railways in western my country that traverse desertified areas have long faced severe threats to transportation safety from sandstorms since their construction and operation. Therefore, sandstorm control has become a critical technical challenge that urgently needs to be addressed in railway construction and operation. Sections of the Lanzhou-Xinjiang, Baotou-Lanzhou, Qinghai-Tibet, Southern Xinjiang, Taiyuan-Zhongwei-Yinchuan, Lhasa-Xigaze, and Linfen-Ceke railways pass through desertified areas, where sandstorm hazards are particularly prominent. To ensure smooth operation, railway operators must invest significant funds, materials, and manpower annually in maintenance and repairs, which not only increases operating costs but also severely disrupts normal transportation. Existing sand control methods are relatively simplistic, with insufficient attention paid to the management of accumulated sand. Summary of the Invention

[0015] Figure 1 An exemplary system architecture 100 is shown, which can be applied to embodiments of the railway sand control belt design method or apparatus for degraded grassland areas of this disclosure.
[0016] like Figure 1 As shown, system architecture 100 may include terminal devices 101, 102, and 103, a network 104, and a server 105. Network 104 serves as the medium for providing communication links between terminal devices 101, 102, and 103 and server 105.

[0018] Terminal devices 101, 102, and 103 can be either hardware or software. When terminal devices 101, 102, and 103 are hardware, they can be various electronic devices, including but not limited to smartphones, tablets, in-vehicle computers, laptops, and desktop computers.

[0021] It should be noted that the railway sand control belt design method for degraded grassland areas provided in this embodiment can be executed by terminal devices 101, 102, and 103, or by server 105. Correspondingly, the railway sand control belt design device for degraded grassland areas can be installed in terminal devices 101, 102, and 103, or in server 105.
[0022] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.
[0023] Figure 2 A flow chart 200 illustrates an embodiment of the railway sand-control belt design method for degraded grassland areas disclosed herein. (See also:) Figure 2 As shown, the railway sand control belt design method for degraded grassland areas in this embodiment may include the following steps: Step 201: Obtain information on wind and sand, geological information, vegetation information, and the location information of the target railway in the degraded grassland area.
[0024] In this embodiment, the implementing entity of the railway sand control belt design method in degraded grassland areas (e.g., Figure 1The terminal devices 101, 102, 103, or server 105 shown can acquire information on wind erosion, geology, vegetation, and the location of the target railway in degraded grassland areas through various means. Wind erosion information can be obtained from meteorological information and satellite imagery of degraded grassland areas, and may include prevailing wind direction, wind speed, wind frequency, and the movement patterns and intensity of sand dunes. Geological information may include topography, soil type, sandy soil moisture content, and groundwater depth. Vegetation information may include remaining native plant species, coverage, and growth status. The location information of the target railway may include the location of the target railway, the preset relative distance between the roadbed and the protected area, and the preset height difference.
[0025] Step 202: Determine the target area of the sand control belt based on wind and sand information and location information.
[0026] In this embodiment, the target area of the sand control belt can be determined based on wind and sand information and location information. For example, the sand movement speed can be determined based on wind direction, wind speed, and wind frequency. The radius of the target area is then determined based on this movement speed. Then, using each point on the target railway as the center and the radius of the target area as the radius, the intersection of these determined circles is taken as the target area of the sand control belt. Alternatively, the amount of sand dune movement caused by a single strong wind can be determined based on the movement pattern and intensity of the sand dunes. The target area of the sand control belt is determined based on a pre-established correspondence between sand dune movement and the area.
[0027] Step 203: Based on geological and vegetation information, determine the sub-regions corresponding to various sand-control structures within the target area.
[0028] In this embodiment, based on geological and vegetation information, sub-regions corresponding to various sand-control structures can be further determined within the target area. Specifically, the height and range of the mesh-like sand-control structure can be determined based on the topography in the geological information. For example, if the topography includes a hill, the height of the mesh-like sand-control structure can be slightly lower, and the range can be slightly narrower. Here, "slightly lower" and "slightly narrower" can be understood as taking the lowest value within a preset range. The implementing entity can also determine the seedlings, planting density, and planting range used for sand control based on the soil type, sand moisture content, and groundwater depth in the information. For example, if the soil type is water-fixing and the sand moisture content is high, water-loving plants can be used. In areas with high sand moisture content, the planting density can be higher. The planting range can be determined based on the range of sand with moisture content within a preset range. In some specific practices, the sand-control structure can include a mesh-like sand-control structure, a vegetation sand-control strip, and a grass-and-tree sand-control strip. Among them, the mesh-like sand-control structure is located far from the target railway and is a strip structure. The vegetation-based sand control strip is located inside the mesh-like sand control structure and mainly consists of plants suitable for growth in degraded grassland areas. The vegetated sand control strip is located near the target railway and mainly consists of vegetation and stones used to stabilize the railway.
[0029] Step 204: Determine the construction plan for the corresponding sand control structure in each sub-region.
[0030] After determining the sand-control structures to be installed in each sub-area, the construction plans for each structure can be further determined. For example, for a mesh-like sand-control structure, its installation process can be determined. For a plant-based sand-control strip, the installation process for its water supply device can be determined first, followed by the planting process for the plants. For a vegetation-based sand-control strip, the planting process for the vegetation and the placement process for the stones can be determined first, and so on.
[0031] Step 205: Output the construction plan.
[0032] Once the construction plan is determined, it can be output for technical personnel to review.
[0033] The railway sand-control belt design method for degraded grassland areas provided in the above embodiments of this disclosure can determine the target area of the sand-control belt based on the wind and sand information, geological information, vegetation information, and location information of the target railway in the degraded grassland area, and further determine the sub-areas corresponding to various sand-control structures. It further determines and outputs the construction schemes for each sand-control structure within each sub-area. This achieves automatic design of the sand-control belt and incorporates multiple sand-control structures in the design scheme, thereby improving sand-control performance.
[0034] See also Figure 3 This illustrates flow 300 of another embodiment of the railway sand-control belt design method for degraded grassland areas according to this disclosure. Figure 3 As shown, the method in this embodiment may include the following steps: Step 301: Obtain information on wind and sand, geological information, vegetation information, and the location information of the target railway in the degraded grassland area.
[0035] Step 302: Based on the wind and sand information, determine the prevailing wind direction, wind speed, wind frequency, and sand dune movement patterns and intensity in the degraded grassland area; based on the prevailing wind direction, wind speed, wind frequency, sand dune movement patterns and intensity, and the location information of the target railway, determine the protection area; based on the location information, determine the preset distance and preset height difference corresponding to the target railway; based on the preset distance, preset height difference, and protection area, determine the target area of the sand control belt.
[0036] In this embodiment, wind and sand information can be analyzed to determine the prevailing wind direction, wind speed, wind frequency, and dune movement patterns and intensity in the degraded grassland area. Then, based on this information and the location information of the target railway, a protection zone is determined. Here, the size of the protection zone can be determined by multiplying the wind speed and wind frequency. Furthermore, on the side facing the prevailing wind direction, the protection zone is appropriately enlarged by multiplying the aforementioned size by a coefficient greater than 1. On the other side facing the prevailing wind direction, the protection zone is appropriately reduced by multiplying the aforementioned size by a coefficient less than 1.
[0037] After determining the protected area, the preset distance and preset height difference corresponding to the target railway can be further determined based on the location information. Here, the preset distance refers to the distance between the target railway and the protected area. It is understandable that to ensure the normal operation of trains, a certain distance of clearance needs to be reserved on both sides of the target railway. The range of this reserved area varies depending on the region. The preset distance to the target railway can be set in advance. The preset height difference refers to the height difference between the roadbed and the protected area.
[0038] The implementing entity can further determine the target area of the sand-control belt based on preset distances, preset height differences, and the protected area. Specifically, the area outside the preset distance range of the target railway within the protected area can be designated as the target area of the sand-control belt.
[0039] Step 303: Based on geological information, determine the topography, soil type, sandy soil moisture content, and groundwater depth; based on topography, determine the first sub-region of the outer sand control belt; based on soil type, sandy soil moisture content, groundwater depth, and vegetation information, determine the second sub-region of the middle sand control belt; based on preset distance and preset height difference, determine the third sub-region of the inner sand control belt.
[0040] The implementing entity can also analyze geological information to determine topography, soil type, sandy soil moisture content, and groundwater depth. Based on the topography, the first sub-region of the outer sand control belt can be determined. Further, based on soil type, sandy soil moisture content, groundwater depth, and vegetation information, the second sub-region of the middle sand control belt can be determined. Finally, based on preset distances and preset height differences, the third sub-region of the inner sand control belt can be determined. In this embodiment, the first sub-region can be called the leading sand-blocking and promoting zone (outer zone), located at the outermost edge where wind and sand activity is most intense. Its main function is to intercept most of the sand transport and promote sand particle settling, creating a relatively stable environment for the inner side. The second sub-region can be called the core sand-fixing and restoration zone (middle zone), located in the middle area and is the core of ecological restoration. Its main function is to completely fix the sand surface and establish a stable growth base for plants. The third sub-region can be called the roadbed protection zone (inner zone): adjacent to the railway roadbed. Its main function is to prevent sporadic sand particles from encroaching on the roadbed and to act as a final buffer.
[0041] Step 304: Set up a mesh sand barrier of a preset height in the first sub-area; set up a reed mesh sand barrier in the second sub-area; and set up herbaceous plants and firebreaks in the third sub-area.
[0042] In this embodiment, a "high-rise HDPE (high-density polyethylene) mesh sand barrier" can be deployed in the leading sand-blocking and promoting zone. Here, a durable HDPE mesh sand barrier, 1.0-2.0 meters high, can be selected. It should have a permeable structure (air permeability of approximately 30%-40%). This design aims not to completely block the sand, but rather to reduce wind speed, causing a large amount of sand particles in the wind-blown sand flow to deposit in front of and behind the sand barrier, creating a "sand-buried" environment. This environment is actually conducive to the seed germination and growth of certain deep-rooted psammophytic plants.
[0043] In the core sand-fixing and restoration zone, "low-lying vertical grid sand barriers" are deployed. These can be environmentally friendly and cost-effective reed grid sand barriers, 0.5 meters high. A tight structure and medium-to-large grid (2.5m x 2.5m squares) are used. The goal in this area is to minimize surface wind speed (below the wind speed at which sand is blown), fix surface sand particles, and create a "microenvironment" protected from wind erosion, providing crucial shelter for plant seedlings.
[0044] "Surface covering for sand fixation" is employed in the roadbed slope toe protection zone. Specifically, a grass seeding area can be designated at the roadbed slope toe. The purpose of this operation is to prevent sand from crossing the leading sand-blocking and promoting zone and the core sand-fixing and restoration zone onto the railway line, thus adsorbing and fixing it near the herbaceous plants. Considering the potential fire hazards that may arise from lush vegetation, a firebreak is also set up near the roadbed slope toe, which can also serve as a buffer zone in the wind-blown sand movement trajectory, preventing sand from crossing the railway line.
[0045] Figure 4A schematic diagram of a railway sand control structure combining vertical sand barriers and multi-layered vegetation is shown in this embodiment. Figure 4 In the middle section, a 1.5-meter-wide firebreak is set up at the toe of the roadbed slope near the railway. Adjacent to this firebreak is a grass seeding area where perennial herb seeds can be sown. Next is a reed grid, with two saxaul plants planted in each square. The reed grid is 2.5 meters x 2.5 meters in size and 0.5 meters high. The row and column spacing of the grid can be 3 meters (e.g., ...). Figure 5 (As shown). An HDFE high vertical mesh, 1.5 meters high, is installed on the outermost side. Sand removal channels are provided before and after the HDFE high vertical mesh for removing sand.
[0046] Figure 6 The diagram shows a top view and a front view of the HDFE high vertical mesh setup. To improve the stability of the HDFE high vertical mesh, it can be set along the broken lines in the top view.
[0047] Step 305: Set up a sand clearing channel in the first sub-area; set up seedling planting containers in the second sub-area.
[0048] In this embodiment, the planting of organisms is carried out simultaneously with or slightly after engineering measures, and vegetation configuration also follows the zoning principle. When selecting plant species, local native species are given absolute priority, such as Haloxylon ammodendron, Caragana korshinskii, Mongolian crested grass, and Calomelena camara. These plants are drought-resistant, tolerant of poor soil, resistant to sand burial, and have well-developed root systems. Sand-clearing channels are set up before and after the leading sand-blocking and promoting zone. The core sand-fixing and restoration zone is located within the grid of the "reed grid sand barrier," where Haloxylon ammodendron and Caragana korshinskii are planted using direct seeding during the rainy season or container seedling planting. The sand deposited by the sand barrier provides nutrients and water for seed germination and seedling growth, and water-retaining agents are used to greatly improve the survival rate. The roadbed slope protection zone is equipped with a "densely planted perennial herb protection zone," selecting herbaceous plants with dense root systems and good slope protection effects, such as Mongolian crested grass and Calomelena camara. Figure 7 The elevation view of the jade-faced container is used.
[0049] Step 306: Before setting up sand control belts in each sub-area, set up water storage tanks and drip irrigation main pipelines in the target area; in response to confirming that the drip irrigation main pipelines are set up, set up mesh sand barriers in the first area and drip irrigation branch pipelines in the second sub-area; in response to confirming that the drip irrigation branch pipelines are set up, set up reed grids in the second sub-area and plant seedlings in the reed grids; in response to confirming that the seedlings are planted, close the reed grids.
[0050] In this embodiment, before setting up sand-control belts in each sub-region, water storage tanks and main drip irrigation pipelines can be installed in the target area first. Water from the storage tanks can enter the main drip irrigation pipelines to provide moisture for the seedlings in the second sub-region. After the main drip irrigation pipelines are installed, a mesh sand barrier can be set up in the first region. Then, drip irrigation branch pipelines can be installed in the second sub-region. When installing the drip irrigation branch pipelines, they can be buried by digging trenches of fixed size and depth in the second sub-region. After the drip irrigation branch pipelines are installed, reed grids can be further set up in the second sub-region, and seedlings can be planted in the reed grids. After the seedlings are planted, the reed grids are sealed off. Figure 8 This is a schematic diagram of a high-pressure water storage tank drip irrigation system. Figure 8 The water storage tank can hold 10-20 tons of water. To increase the outlet pressure, the tank can be placed at a predetermined height using a steel support. A water outlet pipe is connected to the tank's outlet, which in turn connects to the main drip irrigation pipeline, supplying water from the tank into the main pipeline. The main pipeline then distributes the water to various branch pipelines to supply water to the seedlings.
[0051] Step 307: Output the above construction plan.
[0052] Technical personnel can review the above construction plan and modify or adjust it based on their experience.
[0053] In some optional implementations of this embodiment, the reed squares can be arranged closely to form a grid, and the reed squares can be squares of a preset size and preset height.
