Abstract
Description
Technical Field
[0001] The utility model relates to a wind-suppressing and sand-blocking barrier, in particular to a reed sand barrier, and belongs to the technical field of sand prevention and fixation facilities. Background Art
[0002] In the desert areas of northwest my country, with vast geographical areas and rich mineral resources, a large number of roads, railways, mines and other infrastructure must be built. However, sandstorms and dust storms often rage here all year round, and a large number of structures and properties are severely damaged and affected all year round. Many infrastructures must be protected, and various measures must be taken to block and fix sand to reduce losses.
[0003] People have come up with many ways to control the wind and sand in order to protect the structures needed for people's production and life. The main measures are: (1) Using concrete slabs, sleepers, etc. to make various high vertical sand barriers, and combining them with straw, wheat straw, etc. to make low sand fixation grids. The effect is good and has been widely promoted in many places. However, the service life of straw is very short, and it usually rots and becomes ineffective after two or three years. (2) Using concrete bases, concrete columns, and steel mesh, plastic mesh, etc. as high vertical sand barriers, the sand blocking effect is also good, but the construction cost is very high and the construction is very inconvenient.
[0004] Existing products have significant shortcomings: Many existing technologies for sand fixation have been implemented, but most have various problems. Some are too expensive, some have a short service life, and some may cause certain pollution to the environment. Therefore, further improvement is needed. Utility Model Content
[0005] The purpose of the present invention is to solve the above shortcomings and provide a sand barrier that rationally utilizes natural resources, reduces carbon emissions during the production process, and has strong sand prevention and fixation capabilities.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0007] A sand barrier comprises several upright posts and reed bundles; several hooks are provided on one side or both sides of the upright posts; the two ends of the reed bundles are respectively connected to corresponding hooks; the several reed bundles are evenly distributed along the vertical direction of the upright posts at both ends; vertical reinforcements and transverse reinforcements are also provided between the two upright posts.
[0008] Furthermore, each of the reed bundles is wrapped with iron wire; 5-20 reed bundles are connected between any two columns; and the reed bundles correspond to the hooks one by one.
[0009] Furthermore, the spacing between upper and lower adjacent reed bundles is 2-5CM; the iron wire is galvanized braided iron wire; the specification of the iron wire is 18#.
[0010] Furthermore, the columns are concrete columns; the columns are square columns; the columns are set on a C30 concrete foundation; the spacing between the columns is 2.0-5.0M.
[0011] Furthermore, the vertical reinforcement members and the transverse reinforcement members are vertical reinforcing steel strands and transverse reinforcing steel strands respectively.
[0012] Furthermore, both ends of the transverse reinforcing steel strands are connected to hooks; both ends of the vertical reinforcing steel strands are connected to the transverse reinforcing steel strands; and the vertical reinforcing steel strands and the transverse reinforcing steel strands are staggered.
[0013] Furthermore, the intersection nodes of the vertical reinforcing steel strands and the transverse reinforcing steel strands are connected by binding wires; the binding wires are galvanized iron wires.
[0014] This utility model has the following beneficial effects: Horizontally arranged reed bundles can break up wind shear, providing enhanced wind blocking. Furthermore, while vertical placement limits the height of reeds to a maximum of 3 meters, this horizontally arranged sand barrier design allows for heights of 3 to 5 meters, or even higher. Sand barriers of any height can be constructed regardless of reed length. The spacing between columns can be arbitrarily adjusted. By suspending the reed bundles on horizontal steel hinges, the spacing between columns is not limited by reed length, reducing the number of columns and foundations, and effectively lowering project investment.
[0015] At the same time, in Gobi floodplains, the lower part is suspended to allow water to flow through, preventing erosion or burial by sand. The material can be made of reeds, branches, bamboo, bamboo strips, wood, or steel, and is not limited by the material. It is durable, inexpensive, easy to implement, has good protection effects, and is pollution-free, playing an important role in sand control. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A sand barrier comprises several upright posts 1 and reed bundles 2; several hooks 3 are provided on one side or both sides of the upright posts 1; the two ends of the reed bundles 2 are respectively connected to the corresponding hooks 3; the several reed bundles 2 are evenly distributed in the vertical direction of the upright posts 1 at both ends; vertical reinforcements 4 and transverse reinforcements 5 are also provided between the two upright posts 1.
[0024] Furthermore, each of the reed bundles 2 is wrapped with iron wire; 5-20 reed bundles 2 are connected between any two columns 1; and the reed bundles 2 correspond to the hooks 3 one by one.
[0025] Furthermore, the spacing between the upper and lower adjacent reed bundles 2 is 2-5CM; the iron wire is galvanized braided iron wire; the specification of the iron wire is 18#.
[0026] Furthermore, the columns 1 are concrete columns; the columns 1 are square columns; the columns 1 are set on a C30 concrete foundation 7; and the spacing between the columns 1 is 2.0-5.0M.
[0027] Furthermore, the vertical reinforcement 4 and the transverse reinforcement 5 are vertical reinforcing steel strands and transverse reinforcing steel strands respectively.
[0028] Furthermore, both ends of the transverse reinforcing steel strands are connected to the hook 3; both ends of the vertical reinforcing steel strands are connected to the transverse reinforcing steel strands; and the vertical reinforcing steel strands and the transverse reinforcing steel strands are staggered.
[0029] Furthermore, the intersection nodes of the vertical reinforcing steel strands and the transverse reinforcing steel strands are connected by tying wires 6; the tying wires 6 are galvanized iron wires.
[0030] Working principle: The reed bundle 2 must be made of local high-quality reeds, each reed bundle is generally 3-10cm in diameter, and is woven with galvanized iron wire 4. The woven iron wire 4 is generally 18#, twisted and woven into a reed fence. The number of weavings is mostly 5-20, and the gap between the two reed bundles is generally 2-5cm. It is hung on the preset hook 3 of the prefabricated concrete column 1. The column 1 is generally made into a square with a cross-section of about 15-20cm square and a height of 1.5 -3.0 meters, the column spacing is 2.0-5.0 meters, the column 1 is fixed on the C30 concrete foundation 7, and is fixed with horizontal and vertical reinforcing steel strands. The steel strands are generally 4# or 5#, and the horizontal ones can be thicker than the vertical ones. The nodes where the steel strands are cross-connected are tied together with tying wire 6. The tying wire is 12# galvanized iron wire, so that the fence maintains a certain distance from the ground. This distance is generally 10-30cm, thus forming a new type of reed sand barrier.
[0031] Sand barriers break up wind shear, providing a more effective wind-blocking effect. They weaken the wind and trap the sand carried by the wind behind the barrier. Because the lower portion of the barrier is suspended in the air, the wind below carries the sand away from the barrier, preventing it from staying on the barrier. A vortex forms above the barrier, blocking the wind below. This causes the sand to stop at a certain distance from the barrier, preventing it from burying the sand.
[0032] When the sand behind the reed sand barrier exceeds a certain height, a new sand embankment will be formed. The incoming sand will roll along the sand behind the barrier from the top and fall on the leeward side of the sand. Therefore, the sand barrier must be away from protective facilities so that the sand barrier can be used for more than 30 years and achieve the purpose of permanent sand control.
[0033] Finally, it should be noted that the above embodiments are only intended to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
