Description

Technical Field

[0001] This utility model belongs to the field of windbreak and sand fixation technology, specifically relating to a fixing structure for a grid-shaped plate sand barrier. Background Technology

[0002] Desertification is a major ecological problem affecting human survival and development, and it seriously impacts the daily lives and safety of local people.

[0003] Currently, the common methods for stabilizing shifting sand in desert areas include mechanical sand barriers, chemical sand barriers, and plant sand barriers.

[0004] Straw checkerboard sand barriers can not only prevent wind erosion and fix sand, but also intercept precipitation. However, straw sand barriers have a short service life, their resistance to wind erosion decreases, and mechanized harvesting affects the length of straw. The paper industry's demand for straw has also increased, resulting in a severe shortage of straw available for sand fixation.

[0005] Gravel sand barriers and ordinary cement board sand barriers are used to control quicksand. However, due to the difficulty in transporting materials and the high labor costs, the construction of gravel sand barriers requires finding gravel of suitable size, which limits the deployment of gravel sand barriers.

[0006] With the development of materials science and the advancement of desertification control technology, more and more polymer materials are being used to manufacture sand barriers. For example, sand barrier materials made from nylon mesh and high-density polyethylene mesh have a very significant effect on windbreak and sand fixation. However, the materials used in this type of sand barrier are mainly derived from petroleum and cannot degrade in the desert environment, leading to secondary pollution and thus limiting their large-scale application. Polylactic acid (PLA) is mainly derived from corn starch and is naturally biodegradable. More and more researchers are using it to manufacture sandbags and sand barriers, and it has been widely studied in many regions. However, PLA is too expensive to be widely promoted. Wood fiberboard mainly uses natural fibers such as wood fiber, bamboo fiber, or hemp fiber as raw materials. After applying adhesives through atomization, it is cured under high temperature and pressure. Its main raw materials are all natural fibers from nature, which are biodegradable, can be mass-produced industrially, and are low in cost, making it very suitable for manufacturing sand barrier materials. However, as a new type of sand barrier material, how to fix it in the desert has become a very critical problem. While traditional polyethylene (PE) panel sand barriers are widely used, their fixing method primarily involves using steel wire to secure the PE panels to steel reinforcement columns. This method is difficult to implement, inefficient, and leaves a large amount of steel residue in the desert, damaging the desert environment. Therefore, this method is unsuitable for fixing wood fiberboard (WFP) sand barriers. Grass checkerboard sand barriers are fixed by burying them in the sand. However, WFP, being a different material from grass, cannot be fixed by burying; its edges must be secured. Otherwise, it is prone to swaying in windy and sandy conditions, causing the sand barrier to topple. Checkerboard polylactic acid (PLA) bag-shaped sand barriers involve filling sandbags with sand and using the weight of the bags to arrange them in a crisscross pattern. None of these methods are suitable for fixing panel sand barriers; therefore, there is an urgent need to design a checkerboard panel sand barrier fixing structure. Utility Model Content

[0007] To address the problems existing in the prior art, this utility model discloses a fixing structure for a grid-shaped plate sand barrier, and specifically discloses the following technical solutions:

[0008] A fixed structure for a grid-type sand barrier includes a fixed plate and sand-blocking plates. The fixed plate has a slot through the lower middle part and slots on both ends. There are four sand-blocking plates, two of which overlap at one end and are engaged in the slot. The other two sand-blocking plates are inserted into the slots at both ends of the fixed plate. Several air passage holes are evenly distributed on the sand-blocking plates.

[0009] Furthermore, the fixing plate is provided with fixing holes on the side of each slot and on both sides of the sand baffle, and the fixing plate and the sand baffle are fixed together by bolts.

[0010] Furthermore, both sides of the bottom end of the fixing plate are chamfered.

[0011] Furthermore, the sand-blocking board is made of wood fiberboard.

[0012] Furthermore, the total area of ​​all the air passage holes on the sand baffle accounts for 10-70% of the area of ​​the sand baffle.

[0013] Furthermore, the overlap length of the two sand-blocking plates is 2-5cm.

[0014] Furthermore, the height of the slot on the fixing plate is greater than the height of the sand baffle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, the sand-blocking plate can be fixed by a fixing plate, making the entire installation process very convenient and quick, without requiring workers to use additional tools such as cable ties or wire ropes for binding and fixing.

[0017] The sand barrier is made of wood fiberboard, which is conducive to the promotion and application of wood fiberboard in the field of sand prevention and control, and achieves the goal of green, environmentally friendly, degradable and low-cost sand barrier materials.

[0018] The fixing plate is also made of wood, unlike traditional fixing devices that use non-degradable materials such as plastic and steel, thus avoiding secondary pollution to the environment.

[0019] The sand-blocking board is made of wood fiberboard. After aging and degradation, it can increase the organic matter content of the sandy soil, which is beneficial to the growth of desert plants.

[0020] The combination of the fixing plate and the sand-blocking plate forms a cross-shaped structure, which can improve the stability of the sand barrier structure and prevent it from tipping over.

In actual installation, firstly, two sand-blocking plates 6 are overlapped and inserted into the sand. Then, the two sand-blocking plates 6 are secured by the fixing plate 1 through the slot 2. Next, the two sand-blocking plates 6 are inserted into the slots 3 at both ends of the fixing plate 1 and fixed. Then, the fixing plate 1 and other sand-blocking plates 6 that cooperate with the fixing plate 1 are installed again at the free ends of the four sand-blocking plates 6 until they are assembled into a grid-shaped sand barrier that meets the area requirements.

[0028] In this embodiment, fixing holes 4 are provided on the side of each slot 2 on the fixing plate 1 and on both sides of the sand baffle 6.

[0029] In this embodiment, both sides of the bottom end of the fixing plate 1 are chamfered, so that the bottom end of the fixing plate 1 forms a structure that is narrow at the bottom and wide at the top, thereby reducing the resistance during its insertion into the sand.

[0030] In this embodiment, the sand-blocking board 6 is made of wood fiberboard. Specifically, the sand-blocking board 6 is a board made of one or more of wood fiber, bamboo fiber, and hemp fiber, which are then bonded together with adhesive and hot-pressed at high temperature.

[0032] In this embodiment, the total area of ​​all the wind holes 7 on the sand baffle 6 accounts for 10-70% of the area of ​​the wind baffle, which can reduce wind resistance while ensuring the sand blocking effect.

[0033] In this embodiment, the overlap length of the two sand-blocking plates 6 is 2-5cm.

[0034] In this embodiment, the height of the slot 2 on the fixing plate 1 is greater than the height of the sand baffle 6.

[0035] In this utility model, the sand baffle 6 can be fixed by the fixing plate 1. The whole installation process is very convenient and quick, and no workers need to use additional tools such as cable ties and ropes to tie and fix it.

[0036] The sand barrier board 6 is made of wood fiberboard, which is conducive to the promotion and application of wood fiberboard in the field of sand prevention and control, and realizes the goal of green, environmentally friendly, degradable and low cost of sand barrier materials.
