Description

Technical Field

[0001] The invention belongs to the technical field of wind and sand disaster control devices, and specifically relates to a wind and sand protection system and a construction method thereof. Background Art

[0002] At present, various types of sand barriers with sand blocking and sand fixation functions use the following main materials: HDPE board, HDPE net, plant fiber net, nylon net, perforated steel plate, wire mesh, various types of straw, cement board, stone, salt soil block, fin sandbag, etc. Its structure can be roughly divided into plane mesh shape, perforated plate shape, plate shape, block shape, and cylindrical shape. All of them generate turbulence to reduce wind force and block quicksand by airflow passing through meshes, pores, and plate gaps of different materials. Although they all play a certain role in blocking wind and settling sand, there are still many defects and shortcomings in the actual application of sand control projects.

[0003] Its main manifestations are:

[0004] 1. The plane mesh sand barrier is a thin layer (thickness 0.3-0.5mm) plane structure, which makes the wind blocking and wind elimination effect weak, and the sand can easily pass through; an accelerated lifting area will be formed near the top of the sand barrier, which promotes the phenomenon of a large number of sand particles passing over the sand barrier;

[0005] 2. Both the perforated plate and plate-shaped sand barriers reduce the wind force by generating turbulence through the plate holes and gaps. However, this turbulence does not break the airflow into small vortices, so the wind suppression effect is not strong and sand particles can easily pass through.

[0006] 3. Block-shaped and cylindrical sand barriers are relatively low and have no pores. They only act as obstacles in suppressing wind force and blocking quicksand, and their effect in reducing wind force is weak;

[0007] In addition, sand-fixing barriers currently usually use grid structures of different specifications. When the wind and sand fill 2 / 3 of the height of the grid, a stable concave surface will be formed in the grid. At this time, no sand is stored in the grid and no wind erosion occurs. The function is only equivalent to a sandy road surface, so the sand-fixing effect disappears. In actual engineering applications, such sand-fixing barriers cannot be artificially lifted and can only face failure or re-layout, and the original columns cannot be reused. Moreover, the thickness of the accumulated sand is only 20-30cm, the amount of accumulated sand is small, and the protective life is short.

[0008] The above analysis shows that in the current engineering sand control, the wind-blocking and sand-fixing efficiency of sand barriers is low, the amount of sand accumulation is small, and the protection life is short, which cannot meet the control needs of areas with abundant sand sources and serious sand disasters. Summary of the invention

[0009] The main purpose of the present invention is to provide a wind and sand protection system and a construction method thereof to overcome the deficiencies existing in the prior art.

[0010] To achieve the aforementioned object of the invention, the technical solution adopted by the embodiment of the present invention includes:

[0011] An embodiment of the present invention provides a wind and sand protection system, including a first protection zone distributed in the upwind direction of the protected facility, wherein in the first protection zone, an artificial sand-blocking embankment with a height of more than 8 meters, a wire loop-wrapped three-dimensional structure sand-blocking barrier, and an N-shaped suspended storage-type sand-fixing barrier are arranged in sequence from the outside to the inside of the protected facility, and are gradually lifted up by a wire loop-wrapped three-dimensional net sand barrier. The artificial sand-blocking embankment, the wire loop-wrapped three-dimensional structure sand-blocking barrier, and the N-shaped suspended storage-type sand-fixing barrier are respectively distributed in multiple sand-fixing belts, and blank belts are distributed between adjacent sand-fixing belts. The width of the sand-fixing belts and the blank belts is 10-40m.

[0012] Furthermore, the artificial sand-blocking dam comprises a sand-blocking dam body, and the windward side and leeward side slopes of the sand-blocking dam body are both provided with wire-loop-wrapped three-dimensional net sand barriers.

[0013] Furthermore, the wire loop-wrapped three-dimensional net sand barrier includes a wire loop-wrapped three-dimensional net, which is a carpet-like interwoven fabric with multiple intricate pores, wherein the porosity is 15-35%; the carpet-like interwoven fabric is formed by winding and interweaving wire loop-shaped resin filaments, and the wire diameter of the wire loop-shaped resin filaments is 0.5-1.5mm.

[0014] Furthermore, the wire loop-wrapped three-dimensional structure sand barrier includes the wire loop-wrapped three-dimensional net sand barrier and a plurality of extendable columns connected to the wire loop-wrapped three-dimensional net sand barrier, the lower portion of the extendable columns is inserted into the ground, and the wire loop-wrapped three-dimensional net therein is laid along a vertical plane.

[0015] Furthermore, the N-shaped suspended storage-type sand-fixing barrier includes the wire loop-wrapped three-dimensional net sand barrier and a plurality of support columns connected to the wire loop-wrapped three-dimensional net sand barrier, wherein the wire loop-wrapped three-dimensional net is laid in a horizontal direction and the edges on both sides droop naturally, thereby forming a structure with an N-shaped lateral cross-section.

[0016] The embodiment of the present invention also provides a method for constructing the wind and sand protection system, comprising:

[0017] The wire-loop-wrapped three-dimensional net sand barrier is directly laid on the windward and leeward slopes of the sand barrier.

[0018] The wire-loop-wrapped three-dimensional sand barrier is fixed vertically on the ground of the protection area by using extendable columns;

[0019] The n-shaped suspended storage-type sand-fixing barrier is horizontally fixed on the ground of the protection area by using support columns.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The wind and sand protection system of the present invention is based on the principle of far-away blocking and near-fixing. At the far end of the protected object, a 3-cm thick wire-loop-wrapped three-dimensional net sand barrier is used to construct an artificial sand-blocking embankment. The construction process is simple and can be directly laid on the surface without fixing rods. The surface of the sand embankment with a height of more than 8m is kept completely covered, so the sand blocking efficiency is high and the sand fixation capacity is large. As the sand barrier is gradually raised, the height of the sand embankment and the corresponding sand blocking and fixing efficiency will also gradually increase, which can block most of the sand sources in the fixed upwind direction. At the middle end of the protected object, multiple wire-loop-wrapped three-dimensional structures are arranged at intervals to block sand. The barrier has the advantages of being liftable, high in sand blocking efficiency, large in sand blocking capacity and long in protection life; at the near end of the protected object, multiple n-shaped suspended storage-type sand-fixing barriers are arranged at intervals to achieve the purpose of convenient lifting, ultra-high sand accumulation and long-term protection; on the whole, the protection system uses wire loop-wrapped three-dimensional net sand barrier as the main material of the barrier body, which has high sand blocking and fixing efficiency and huge sand blocking and fixing capacity, far exceeding the traditional and conventional plane mesh structure sand blocking and fixing barriers, and is easy to construct and has obvious long-term benefits. It is particularly suitable for use in high-intensity sand transport environments and areas with severe aeolian sand accumulation.

[0022] (2) The wind and sand protection system of the present invention includes a wire loop-wrapped three-dimensional net sand barrier, the main material of which has overall dense, porous and thickened (thickness is 1-3 cm) three-dimensional structural characteristics, which is different from punched, mesh or plate gap type sand barriers; when the wind and sand flow passes through any part of the sand barrier, dense irregular turbulence will be generated inside the wire loop, causing the speed and energy of the airflow to be greatly consumed, so that sand particles are more likely to settle and be fixed in front and behind the sand barrier, and the wind blocking and sand accumulation efficiency is higher.

[0023] (3) The wind and sand protection system of the present invention, wherein the wire loop-wrapped three-dimensional net sand barrier is made of resin, is environmentally friendly, green and pollution-free, and because it is a wire loop-wrapped three-dimensional structure, there is no need for edge locking and it can be cut at will without the edges loosening or tearing, thereby ensuring structural strength and protection life while being easy to use. In addition, because the overall structure is a thick sheet, it can be used interchangeably with the supporting columns and installation auxiliary materials of the currently commonly used nylon mesh fences, and there is no need to separately design and manufacture special columns, etc. It can also be directly fixed on the existing columns, thereby making the wire loop-wrapped three-dimensional net highly versatile and extensible.

[0024] (4) The wind and sand protection system of the present invention, wherein the wire loop-wrapped three-dimensional structure sand barrier has porous and thickened three-dimensional features, which greatly increase the probability of sand being blocked when it hits any position, and the porous structure can slow down the wind passing through, so it has a strong sand filtering function and is more efficient in sand accumulation than a thin-layer flat structure nylon mesh fence.

[0025] (5) The wind and sand protection system of the present invention includes an N-shaped suspended storage-type sand-fixing barrier, a wire-loop-wrapped three-dimensional net fixed on a column by two circular rubber sheets above and below. According to the elevation of the sand surface under the wire-loop-wrapped three-dimensional net, the sand barrier and the sand surface are always kept at a distance of 10-50 cm by raising the height of the fixed rubber sheet, or by raising the original column, or by sleeve-connecting a new column. Since it does not contact the sand surface, it has the function of being easily lifted compared to the traditional square-shaped sand-fixing barrier. The lifting range, i.e., the corresponding sand accumulation thickness, can reach several meters to tens of meters, which is much larger than the 10-30 cm sand accumulation thickness of the traditional square-shaped sand-fixing barrier. In addition, the laying width is 10-40 m. Therefore, the amount of sand accumulation far exceeds that of the traditional square-shaped sand-fixing barrier, and the service life is long.

[0026] (6) The wind and sand protection system of the present invention comprises an N-shaped suspended storage-type sand barrier and an N-shaped suspended flat structure. The edge of the sand barrier is naturally drooping, and the lower edge has a gap of 10-20 cm from the ground. Firstly, this structural design allows the wind and sand flow to smoothly enter the huge N-shaped inverted storage space without obstruction. Secondly, the wind force can be reduced by the swaying of the drooping edge. In addition, the sand barrier isolates and reduces the energy of the upper airflow, and the sand-carrying airflow at the bottom is also consumed by the friction between the sand barrier and the ground. Therefore, compared with the general square sand barrier with a completely open upper part, its sand deposition effect is significantly increased.

[0027] (7) The wind and sand protection system of the present invention, wherein the N-shaped suspended storage-type sand-fixing barrier will not be buried. Even if it is buried, the sand can be lifted and shaken to make the sand flow out from the gaps in the sand barrier and re-suspended on the surface. Therefore, it can be continuously lifted for continuous use, or moved for recycling. In addition, the N-shaped three-dimensional net structure has the functions of shading, windproofing and moisturizing, which can promote the growth of vegetation at the bottom of the N-shaped suspended storage-type sand-fixing barrier.

[0036] In view of the shortcomings of the existing technology, the inventor of this case has proposed a wind and sand protection system after long-term research and practice. Based on the principle of far-away blocking and near-fixing, at the far end of the protection object, a 3cm thick wire-loop-wrapped three-dimensional net sand barrier is used to construct an artificial sand barrier. The construction process is simple and can be laid directly on the surface without fixing rods; the surface of the sand embankment with a height of more than 5m is kept covered as a whole, so the sand blocking efficiency is high and the sand fixing capacity is large; with the gradual increase of the sand barrier, the height of the sand embankment and the corresponding sand blocking and fixing efficiency will gradually increase, which can block most of the sand sources in the fixed upwind direction; at the middle end of the protection object, multiple sand barriers are arranged at intervals. The wire loop-wrapped three-dimensional sand barrier has the advantages of being liftable, high in sand blocking efficiency, large in sand blocking capacity, and long in protection life. At the near end of the protected object, multiple n-shaped suspended storage-type sand-fixing barriers are arranged at intervals, achieving the purpose of convenient lifting, ultra-high sand accumulation, and long-term protection. On the whole, the protection system uses wire loop-wrapped three-dimensional net sand barriers as the main material of the barrier body.

[0038] In some preferred embodiments, the wind and sand protection system also includes a second protection zone distributed downwind of the protected facility, in which wire loop-wrapped three-dimensional structure sand-blocking barriers and N-shaped suspended storage-type sand-fixing barriers are arranged in sequence from the outside to the inside of the protected facility, and the wire loop-wrapped three-dimensional structure sand-blocking barriers and N-shaped suspended storage-type sand-fixing barriers are respectively distributed in multiple sand-fixing belts, and blank belts are distributed between adjacent sand-fixing belts, and the width of the sand-fixing belts and blank belts is 10-40m.

In addition, the laying width is 10-40m. Therefore, the amount of sand accumulation far exceeds that of the traditional square sand-fixing barrier, and the service life is long.
