Abstract
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 a combination of slats. 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 grid sand barriers are all composed of mass-produced sand barrier boards. When used on sand slopes or uneven sandy ground, the bottom of the grid sand barrier cannot fit well against the sand surface, which not only causes assembly problems but also affects the sand-fixing effect. Therefore, there is an urgent need to design a grid-like sand barrier based on a slat combination that can be used on sand slopes or uneven sandy ground for sand control. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model discloses a grid-type sand barrier for sand control and afforestation based on a combination of slats, and specifically discloses the following technical solutions:
[0004] A grid-type sand barrier for sand control based on slats includes several parallel and spaced row-type sand barriers. Each row-type sand barrier includes several sand barrier panels that are sequentially overlapped. A fixing structure is installed at the overlap of two adjacent sand barrier panels to fix the two sand barrier panels. The bottom end of the fixing structure is inserted into the sand. Several sand-blocking strip groups are arranged at intervals between two adjacent row-type sand barriers. The extension direction of the sand-blocking strip groups is perpendicular to the extension direction of the row-type sand barriers. Each sand-blocking strip group includes several sand-blocking strips that are spaced apart and inserted into the sand.
[0005] Furthermore, the sand barrier is provided with a number of ventilation holes evenly distributed throughout.
[0006] Furthermore, the total area of all ventilation holes on the sand barrier accounts for 10-70% of the area of the sand barrier.
[0007] Furthermore, the fixing structure adopts a fixing post with a spike-shaped bottom. The bottom end of the fixing post is inserted into the sand. The top or bottom of the fixing post has a vertical slot, and the overlap of two adjacent sand barrier boards is locked in the vertical slot.
[0008] Furthermore, the fixing structure adopts a fixing plate, the bottom of which has a vertical groove, and both sides of the bottom of the fixing plate have inclined surfaces. The fixing plate is snapped into the joint of two adjacent sand barrier plates through the vertical groove, and the bottom end of the fixing plate is inserted into the sand.
[0009] Furthermore, the fixing structure is made of wood.
[0010] Furthermore, the sand barrier is made of wood fiberboard or wood veneer.
[0011] Furthermore, the overlap length of the two sand barriers is 2-5 cm.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] The grid-type sand barrier of this utility model is formed by the spaced-out row-type sand barriers and the sand-blocking strips between the row-type sand barriers. There is no direct connection between adjacent row-type sand barriers and sand-blocking strips, so it can be flexibly arranged according to the terrain and has stronger adaptability to different terrains.
[0014] The combination of strips in this invention not only helps to prevent sand barriers from being eroded and collapsing in windy and sandy environments, but also allows sand to pass through through the gaps between the sand-blocking strips. The ability of the sand-blocking strips to shake with the wind can reduce wind speed and increase the sand interception rate. Compared with traditional straw grid sand barriers, willow sand barriers, nylon mesh sand barriers, and polylactic acid sand barriers, it has a faster laying speed, simpler construction, and lower labor costs.

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.
[0022] Example 1
[0023] Reference Figure 1-2 A grid-type sand barrier for sand control based on a combination of strips is disclosed. It comprises several parallel and spaced-apart row-type sand barriers. Each row-type sand barrier consists of several sand barrier panels 1 stacked sequentially. A fixing structure is installed at the overlap of two adjacent sand barrier panels 1 to secure them. The bottom end of the fixing structure is inserted into the sand. Several spaced-apart sand-blocking strip groups are arranged between two adjacent row-type sand barriers. The extension direction of the sand-blocking strip groups is perpendicular to the extension direction of the row-type sand barriers. Each sand-blocking strip group includes several sand-blocking strips 2 spaced-apart in the sand. This grid-type sand barrier is formed by spaced-apart row-type sand barriers and sand-blocking strip groups between them. There is no direct connection between adjacent row-type sand barriers, nor between the sand-blocking strips 2, allowing for flexible arrangement according to the terrain and greater adaptability to different terrains.
[0024] In this embodiment, the fixing structure adopts a fixing post 3 with a spike-shaped bottom. The bottom end of the fixing post 3 is inserted into the sand. The bottom of the fixing post 3 has a vertical slot. The overlapping part of two adjacent sand barrier panels 1 is locked in the vertical slot, thereby fixing the two sand barrier panels 1.
[0025] 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, and after degradation, they can also increase the organic matter content of the sand.

The fixing plate 4 is engaged with the overlapping part of two adjacent sand barrier plates 1 through the vertical groove, and the bottom end of the fixing plate 4 is inserted into the sand. In other embodiments, the vertical groove can also be provided at the top center of the fixing plate 4.
[0031] Example 4
[0032] Reference Figure 5 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 5 are evenly opened on the sand barrier 1 to reduce wind resistance and improve the wind resistance of the grid sand barrier. The total area of all ventilation holes 5 on the sand barrier 1 accounts for 10-70% of the area of the sand barrier 1.
