Description

Technical Field

[0001] The invention belongs to the field of wind and sand protection, in particular to a wind and sand protection system. Background Art

[0002] The Gobi Desert is one of the world's vastest deserts and semi-deserts, stretching across the vast expanse of Central Asia and spanning the vast expanses of Mongolia and China. Most areas of the Gobi Desert are not desert, but bare rock. my country's Lanzhou-Xinjiang High-Speed ​​Railway is the first high-speed railway to traverse the Gobi Desert's high-wind zone. From east to west, it passes through four major wind zones: the Yandun, Baili, Sanshili, and Dabancheng wind zones. The high-wind zone stretches 462.41 kilometers, accounting for 65% of the Xinjiang section. These high-wind zones are primarily located at the windward sides of mountain ranges and are characterized by high wind speeds, long wind periods, strong seasonality, stable wind direction, and rapid wind speeds. The Gobi Desert is predominantly a Gobi-type landform, and with annual precipitation below 50 mm, it is an extremely arid region with sparse vegetation and limited survival. Consequently, strong winds can easily generate Gobi sand and gravel flows, carrying gravel with high impact and causing significant damage to road and transportation facilities. Several years ago, the holy shepherds pushed the uneven sand dunes into flat land, and then through vertical deep loosening operations, mixed the hard red mud under the sand layer with the fine sand on the surface, forming a "sand loft" that is conducive to storing water, retaining moisture and fertilizer, and suitable for crop growth.

[0003] Traditional mechanical engineering protection systems have a limited lifespan and require regular cleaning of accumulated sand inside and outside the system to ensure their continued effectiveness. Consequently, they are insufficiently effective in combating the wind and sand disasters in this region. Biological measures, as a potential solution to combat wind and sand disasters, are difficult to implement and costly in this extremely harsh environment. The low survival rate of vegetation makes it difficult to establish a systematic and effective protection system and achieve effective results.

[0004] To address the aforementioned issues, Chinese patent publication CN 109235411 B discloses a prefabricated sand-collecting and water-collecting afforestation system suitable for use in windy and sandy areas. The prefabricated sand-collecting and water-collecting afforestation system comprises a removable sand barrier, a wind-suppressing and dust-reducing buffer net installed on the top of each barrier, sand-collecting and water-collecting ditches located between adjacent barriers, and a vegetation protection belt planted within the ditches. The barrier comprises multiple embankments, the windward side of which is curved, extending along the height of the barrier and forming a depression relative to the barrier. Guide grooves are provided on the curved surface, extending along the height of the barrier.

[0005] This system addresses the existing technical problem of Gobi desert regions being susceptible to the formation of wind-blown sand and gravel flows that damage road and traffic facilities under extremely strong winds. However, due to the varying locations of different sand barriers, their ability to suppress wind and sand varies, and the conditions of adjacent ditches vary, rainwater and sediment accumulated in any one ditch within a short period of time could potentially lead to significant flooding hazards due to the inability to drain them in a timely and necessary manner. Therefore, this proposal proposes a wind and sand protection system to mitigate this risk. Summary of the Invention

[0006] In order to solve the problem that rainwater and sediment accumulated in any of the above-mentioned ditches in a short period of time may cause a large number of hidden dangers of waterlogging due to the inability to discharge them in a timely and necessary manner, the present invention provides a wind and sand protection system to alleviate and balance the obvious gradient pressure difference caused by the gradual accumulation of sand and dust, as well as emergencies such as water discharge, sediment leap, and rainstorms, thereby effectively avoiding a series of waterlogging problems.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a wind and sand protection system, comprising a first sand-blocking dike, a second sand-blocking dike and a third sand-blocking dike arranged in sequence from the protected area to the outside, a first auxiliary ditch is provided between the first sand-blocking dike and the second sand-blocking dike, and a second auxiliary ditch is provided between the second sand-blocking dike and the third sand-blocking dike; the tops of the first sand-blocking dike, the second sand-blocking dike and the third sand-blocking dike are all detachably connected with arc-shaped baffles; the bottoms of the first auxiliary ditch and the second auxiliary ditch are both paved with red mud.

[0008] A connecting pipe is provided at the bottom of the second sand-blocking dam, which connects the first auxiliary ditch and the second auxiliary ditch. A limiting block is fixedly connected to the middle of the connecting pipe, and a sphere for blocking the connecting pipe is slidably fitted on the limiting block; when the sand and water in the first auxiliary ditch and the second auxiliary ditch increase, the sand and water will accumulate in the connecting pipe, and the gradual accumulation of sand and water will gradually increase the pressure on the sphere; when the pressure on one side of the sphere is greater than that on the other side, the sphere will break away from the limiting block.

[0009] The principle and beneficial effects of the above scheme are as follows: when sand blows towards the protected area, the first sand barrier, the second sand barrier, the top of the third sand barrier and the baffle can, to a certain extent, curb the rapid erosion of sand and dust caused by strong winds.

[0010] The first and second auxiliary ditches are paved with red mud, which enhances soil structural stability and effectively prevents silt from forming a consolidation layer within the ditches. As the amount of sand and water in the first and second auxiliary ditches increases, they accumulate in the connecting pipe. This gradual accumulation of sand and water gradually increases the pressure on the sphere. When the pressure on one side of the sphere is greater than the other, the sphere will break away from the retaining block. Therefore, as sand and water gradually accumulate in the first and second auxiliary ditches, they gradually accumulate through the connecting pipe. The connecting pipe, which stores sand and water, forms a valve at the bottom of the second sand barrier through the positioning of the sphere. As the amount of sand and water increases, the pressure on the sphere gradually increases. When the pressure on one side of the sphere exceeds the limit of the retaining block, the sphere breaks away from the retaining block, releasing the sand and water stored in the connecting pipe. Adding devices like connecting pipes effectively alleviates the pressure difference between the first and second auxiliary ditches, enhancing the passability and flow between the two ditches. Alleviate and balance the obvious gradient pressure difference caused by the gradual accumulation of sand and dust, as well as sudden events such as water discharge, sediment leap, and rainstorms, thereby effectively avoiding a series of waterlogging problems.

[0011] Furthermore, when the first auxiliary ditch is connected to the second auxiliary ditch, the red mud layer is turned over and mixed with fine sand to form a sand-covered ridge of soil and sand, and plants are planted on the sand-covered ridge.

[0012] Beneficial effects: By planting plants, a large number of root systems are formed on the "sand cover", which helps to capture fine sand particles with high water content, slow down the speed of water flow, increase the retention time of water flow in the vegetation-covered area, and reduce the probability of floods and rainstorm disasters.

[0013] Furthermore, a baffle net is detachably connected to the top of the baffle.

[0014] Beneficial effects: By connecting the baffles, the height and density of the baffles can be increased, thereby effectively reducing the amount of quicksand entering the protected area, improving the sand blocking efficiency and protecting the ecological environment.

[0015] Furthermore, both ends of the connecting pipe are fixedly connected with a barrier net.

[0016] Beneficial effect: The barrier net can filter out larger impurities and avoid clogging the connecting pipe.

[0017] Furthermore, the baffle includes a hollow first connecting plate and a second connecting plate, the second connecting plate is slidably fitted in the top of the first connecting plate, and the top of the second connecting plate is slidably fitted with a third connecting plate; the first connecting plate and the second connecting plate are both provided with a number of threaded holes, and the threaded holes are both threaded with screws.

[0018] Beneficial Effects: The height of the baffle can be adjusted by sliding the second connecting plate onto the first connecting plate, and then sliding the third connecting plate onto the second connecting plate. The height of the baffle can then be fixed using screws. This allows the baffle to be adjusted to suit specific circumstances, better adapting to different environments and improving protective effectiveness. The height-adjustable baffle can be more flexibly adapted to different needs and can be flexibly adjusted based on actual conditions. Furthermore, when the baffle is finished or needs to be moved, it can be lowered, making it easier to move.

[0019] Furthermore, the baffle is hinged with a support rod on the side close to the protected area, a fixing rod is hinged in the middle of the support rod, a through hole is provided at one end of the fixing rod away from the support rod, and an L-shaped auxiliary rod is provided on the baffle, which can be inserted into the through hole.

[0020] Beneficial effect: The support rod can facilitate supporting the baffle, and when the auxiliary rod is inserted into the through hole at one end of the support rod, the support rod, the auxiliary rod and the baffle form a triangle, thereby enhancing the stability of the support rod and the baffle.

[0021] Furthermore, after plants are planted on the sand bank, the first sand barrier, the second sand barrier and the third sand barrier are moved away from the protected area.

[0022] Beneficial effects: This allows the planting area to gradually move forward and expand, increasing the density and range of the plant barrier, thereby effectively blocking the invasion of wind and sand, and improving the overall protective effect of the wind and sand protection system.

[0023] Furthermore, diversion grooves are provided on the tops of the first sand-blocking dike, the second sand-blocking dike and the third sand-blocking dike on the side away from the protected area.

[0024] Beneficial effect: The diversion trough can facilitate the diversion of wind, sand and water. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 2 4 is a cross-sectional view of a baffle according to an embodiment of the present invention. DETAILED DESCRIPTION

[0027] The following is further described in detail through specific implementation methods:

[0028] The figure marks in the drawings of the specification include: first sand-blocking dike 1, second sand-blocking dike 2, third sand-blocking dike 3, protected land 4, first auxiliary ditch 5, second auxiliary ditch 6, baffle 7, red mud 8, connecting pipe 9, limit block 10, sphere 11, plant 12, barrier net 13, barrier net 14, first connecting plate 15, second connecting plate 16, third connecting plate 17, screw 18, support rod 19, fixing rod 20, auxiliary rod 22.

[0029] Example 1

[0030] The embodiment is basically as shown in the attached Figure 1 and attached Figure 2 As shown:

[0031] A wind and sand protection system includes a first sand-blocking dike 1, a second sand-blocking dike 2 and a third sand-blocking dike 3, which are stacked in sequence from the protected area 4 to the outside. A first auxiliary ditch 5 is dug between the first sand-blocking dike 1 and the second sand-blocking dike 2, and a second auxiliary ditch 6 is dug between the second sand-blocking dike 2 and the third sand-blocking dike 3; the tops of the first sand-blocking dike 1, the second sand-blocking dike 2 and the third sand-blocking dike 3 are all detachably connected with arc-shaped baffles 7 by screws; the bottoms of the first auxiliary ditch 5 and the second auxiliary ditch 6 are both paved with red mud 8.

[0032] A connecting pipe 9 is buried at the bottom of the second sand-blocking dam 2, which connects the first auxiliary ditch 5 and the second auxiliary ditch 6. The middle part of the connecting pipe 9 is fixedly connected to a limiting block 10 by screws, and a sphere 11 is slidably fitted on the limiting block 10 for sealing the connecting pipe 9; when the sand and water in the first auxiliary ditch 5 and the second auxiliary ditch 6 increase, the sand and water will accumulate in the connecting pipe 9, and the gradual accumulation of sand and water will gradually increase the pressure on the sphere 11; when the pressure on one side of the sphere 11 is greater than that on the other side, the sphere 11 will break away from the limiting block 10.

[0033] The specific implementation process is as follows: when the wind and sand blow from right to left toward the protected area 4, the first sand barrier 1, the second sand barrier 2, the top of the third sand barrier 3 and the baffle 7 can to a certain extent curb the rapid erosion of sand and dust caused by the strong wind.

[0034] The first and second auxiliary ditches 5 and 6 are paved with red mud 8, which enhances soil structural stability and effectively prevents silt from forming a soil consolidation layer within the ditches. As the amount of sand and water in the first and second auxiliary ditches 5 and 6 increases, they accumulate in the connecting pipe 9. This gradual accumulation of sand and water gradually increases the pressure on the sphere 11. When the pressure on one side of the sphere 11 is greater than the other, the sphere 11 will break away from the retaining block 10. Therefore, as sand and water gradually accumulate in the first and second auxiliary ditches 5 and 6, they gradually accumulate through the connecting pipe 9. The positioning of the sphere 11 in the connecting pipe 9, which stores sand and water, forms a valve at the bottom of the second sand barrier 2. As the amount of sand and water gradually increases, the pressure on the sphere 11 gradually increases. When the pressure on one side of the sphere 11 exceeds the limit of the retaining block 10, the sphere 11 will break away from the retaining block 10, releasing the sand and water stored in the connecting pipe 9. The addition of devices such as the connecting pipe 9 effectively alleviates the pressure difference between the first and second auxiliary ditches 5 and 6, enhancing the passability and flow between the two ditches. Alleviate and balance the obvious gradient pressure difference caused by the gradual accumulation of sand and dust, as well as sudden events such as water discharge, sediment leap, and rainstorms, thereby effectively avoiding a series of waterlogging problems.

Then, use the screw 18 to fix the height of the baffle 7. The height of the baffle 7 can be adjusted according to actual conditions, thereby better adapting to different environments and improving the protective effect. The adjustable height of the baffle 7 can more flexibly adapt to different needs and can be flexibly adjusted according to actual conditions.
