Description

Technical Field

[0001] This utility model belongs to the field of windbreak and sand fixation technology, specifically relating to a grid-type sand barrier for sand control based on an interlocking structure. Background Technology

[0002] Wind and sand disasters cause serious harm to people's production, lives, transportation, and personal safety, therefore, various sand control engineering technologies must be adopted for prevention and control. Laying grid-like sand barriers on the sand surface is currently a very effective sand control measure. It mainly achieves the purpose of wind and sand control by changing the ground characteristics, increasing surface roughness, reducing wind speed near the protected area, and reducing wind erosion inside and behind the sand barrier. Wooden plank sand barriers are gradually being used in sand control due to their low cost and environmental friendliness. However, existing wooden plank sand barriers require connectors for fixation, making assembly very inconvenient. They also lack necessary fixing structures, have poor stability, and are easily blown away or even disintegrate in strong winds. Therefore, there is an urgent need to design a grid-like sand barrier for sand control based on an interlocking structure that is easy to assemble and has strong stability. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a grid-type sand barrier for sand control and afforestation based on an interlocking structure, and specifically discloses the following technical solution:

[0004] A grid-type sand barrier for sand control based on an interlocking structure includes a grid body, which is composed of several grid units. Each grid unit is composed of four sand barrier panels vertically spliced ​​together. Each sand barrier panel has two slots. Two adjacent sand barrier panels that are perpendicular to each other are interlocked through the slots. The width of the slot is 2-3 times the thickness of the sand barrier panel. Two adjacent grid units share one sand barrier panel.

[0005] Furthermore, the depth of the slot is 1 / 3 to 2 / 3 of the width of the sand barrier.

[0006] Furthermore, both slots are located on the same side of the sand barrier, and the two slots are at the same vertical distance from the center line of the sand barrier.

[0007] Furthermore, the two slots are respectively disposed on both sides of the sand barrier, and the two slots are equidistant from the center line of the sand barrier.

[0008] Furthermore, it also includes several fixing structures, which are installed at the edges of the grid body to fix the edges of the grid body to the sand surface.

[0009] Furthermore, the fixing structure includes a fixing column, the bottom of which has a cross-shaped groove extending from bottom to top. The depth of the groove is greater than the width of the sand barrier. The fixing column is fixed to the sand barrier connection node located at the edge of the grid body through the groove. The bottom end of the fixing column is set as a spike.

[0010] Furthermore, the fixing structure is a fixing plate with a vertical groove in the middle. The bottom of the fixing plate is provided with inclined surfaces on both sides of the vertical groove. The sand barrier plate at the sand barrier plate connection node parallel to the edge of the grid body is snapped at the connection node or snapped at the connection node along the diagonal.

[0011] Furthermore, the fixing structure is made of wood.

[0012] Furthermore, the sand barrier is provided with a number of ventilation holes evenly distributed throughout.

[0013] Furthermore, the sand barrier is made of wood fiberboard or wood veneer.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this utility model, the sand baffles are connected by slots, which facilitates installation and disassembly.

[0016] The sand barrier panels are connected and fixed by interlocking, which avoids the sand barrier from being eroded and falling over in the wind and sand environment. The construction is simple, the amount of materials required is far less than that of traditional straw grid sand barriers, the cost is low and the laying efficiency is high.

[0017] The edges of the main grid are equipped with a fixing structure that can fix the main grid to the sand surface and prevent the main grid from being overturned or blown away by the wind.

[0018] Both the sand barriers and the fixing structure are made of wood, which is biodegradable and will not cause pollution to the environment. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Reference Figure 1-5 A grid-type sand barrier for sand control based on an interlocking structure includes a grid body, which is composed of several grid units. Each grid unit is composed of four sand barrier plates 1 vertically spliced ​​together to form a square structure. Each sand barrier plate 1 has two slots 2. Two adjacent sand barrier plates 1 that are perpendicular to each other are interlocked through the slots 2. The width of the slot 2 is 2-3 times the thickness of the sand barrier plate 1. Two adjacent grid units share one sand barrier plate 1.

[0032] In this embodiment, all sand barrier plates 1 have the same structure and size, which facilitates mass production. During actual installation, two interlocking sand barrier plates 1 are placed in opposite directions, that is, the slot 2 of one sand barrier plate 1 faces upward and the corresponding slot 2 on the other sand barrier plate 1 faces downward, thereby achieving interlocking.

[0033] In this embodiment, the depth of the slot 2 is 1 / 3 to 2 / 3 of the width of the sand barrier 1.

[0034] In this embodiment, both slots 2 are located on the same side of the sand barrier 1, and the vertical distances from the two slots 2 to the center line of the sand barrier 1 are the same.

[0035] In this embodiment, several fixing structures are also included. The fixing structures are installed at the edge of the grid body and are used to fix the edge of the grid body to the sand surface.

[0036] In this embodiment, the fixing structure includes a fixing column 3. The bottom of the fixing column 3 has a cross-shaped groove 4 extending from bottom to top. The depth of the groove 4 is greater than the width of the sand barrier 1. The fixing column 3 is fixed to the sand barrier connection node located at the edge of the grid body via the groove 4. The connection node can be inserted into the cross-shaped groove 4 from the bottom. The fixing column 3 not only fixes the grid body to the sand surface, improving its wind resistance, but also improves the connection stability at the corresponding connection node. In other embodiments, the number of fixing structures can be set according to the actual situation. One fixing structure can be set at each connection node at the edge of the grid body, or several connection nodes can be selected for fixing structures. Furthermore, to improve stability, fixing structures can also be installed at connection nodes located outside the edge.

[0037] In this embodiment, the bottom end of the fixed column 3 is set as a spike, which makes it easier and less strenuous to insert the bottom end into the sand.

[0038] In this embodiment, the fixing structure is made of wood, and the sand barrier 1 is made of wood fiberboard or wood veneer. Both can be degraded, which not only will not cause pollution to the environment, but will also increase the organic matter content of the sand after degradation.

[0039] Example 2

[0040] Reference Figure 6 The technical solution of this embodiment is basically the same as that of embodiment 1, with the only difference being that in this embodiment, two slots 2 are respectively disposed on both sides of the sand barrier 1, and the vertical distance from the two slots 2 to the center line of the sand barrier 1 is the same. After the four sand barriers 1 in this embodiment are spliced ​​into a grid unit, the four sand barriers 1 can form a clockwise or counterclockwise interlocking relationship, thereby making its structure more stable.

[0041] Example 3

[0042] Reference Figure 7-8The technical solution of this embodiment is basically the same as that of Embodiment 1, with the only difference being that: in this embodiment, the fixing structure is a fixing plate 5 with a vertical groove in the middle. The bottom of the fixing plate 5 has inclined surfaces on both sides of the vertical groove. The fixing plate 5 is attached to the sand barrier at the connection node of the sand barrier at the edge of the grid body, either parallel to the connection node or diagonally, with its bottom end inserted into the sand, thereby fixing the edge of the grid body. In other embodiments, a fixing plate can also be attached to each side of the sand barrier at the connection node, i.e., two parallel fixing plates can be installed.

[0043] Example 4

[0044] Reference Figure 9 The technical solution of this embodiment is basically the same as that of embodiment 1. The only difference is that in this embodiment, a number of ventilation holes 6 are evenly opened on the sand barrier plate 1, which can reduce wind resistance and improve the wind resistance of the sand barrier.

[0045] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
