Description

Technical Field

[0001] The invention relates to the technical field of windbreak and sand fixation devices, in particular to a multi-layered windbreak and sand fixation device. Background Art

[0002] Bentonite, also known as bentonite, bentonite, or bentonite rock, is primarily composed of montmorillonite, which accounts for 85-90% of the total mineral content. Montmorillonite is responsible for many of the clay's properties. Montmorillonite can appear in a variety of colors, including yellow-green, yellow-white, gray, and white. It can be dense, lumpy, or loose, like a clay. It feels slippery when rubbed between fingers. Small lumps expand several times, up to 20-30 times, in volume when water is added. It suspends in water and becomes a paste when water is scarce. Montmorillonite's properties are related to its chemical composition and internal structure.

[0003] Considering that bentonite can swell when it comes into contact with water and can be mixed with water to form a paste, bentonite can usually be used for water retention and can be applied to the field of wind and sand fixation. However, bentonite cannot be used alone, otherwise it is easy to be lost, which will reduce the effect of wind and sand fixation. Therefore, it is generally used in conjunction with wind and sand fixation devices to reduce the loss rate of bentonite.

[0004] Generally, traditional wind-proof and sand-fixing devices are usually a single fixed frame with a protective net added on top, and then bentonite is placed inside the fixed frame, so that it can be prevented from being lost under the action of the protective net. However, this method makes the bentonite still cover the surface of the soil, and in the process of soil and water loss at the bottom, the bentonite will still be lost. After the bentonite is mixed with the soil and then absorbs water, it is easy to cause the bentonite to separate from the soil, thereby reducing the overall water retention and sand fixation effect. At the same time, when the wind is strong, it is very easy to pass through the holes in the top protective net, causing the bentonite and the dry mud and sand at the bottom to be blown away, thereby causing soil and water loss.

[0005] In summary, it is necessary to propose a multi-layered wind and sand fixation device to solve the above problems. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figures 1 to 10 , the present invention provides a technical solution:

At the same time, the covering plate 37 can be folded and propped up in rainy weather or windless weather, so that water can enter the interior for absorption and water retention. Under the action of the disassembly and assembly connection structure 4, multiple reinforcement frames 1 can be connected.

At this time, the excavated soil mixed with bentonite is placed inside the placement frame 26, and the rectangular ring clamping block 22 is clamped with the rectangular ring clamping groove 21, and then the threaded clamping rod 25 is fixed with the first screw hole 23 and the second screw hole 24. At this time, the auxiliary connecting block 217 is pulled to separate the clamping rod 218 from the first clamping hole 216 and the second clamping hole 219.
