[0002] The research and practice of wind and sand control engineering in my country require that the goal is to closely focus on the social and economic development and environmental restoration of the windy and sandy areas in northwest my country. The core of wind and sand control engineering is to take a variety of technical measures to reduce the amount of sand in the air flow, weaken the wind speed near the surface, and delay or prevent the movement of sand dunes, so as to achieve the purpose of weakening or avoiding the harm of wind and sand. Engineering sand control can be divided into three types according to its action principle and function: sand fixation measures, sand blocking measures and transport measures. Among them, sand fixation measures, on the one hand, seal the sand source near the line and inhibit the activity of quicksand to reduce or eliminate the harm to the line; on the other hand, protect the roadbed slopes and other places to prevent wind erosion. At the same time, under the premise of controlling the wind erosion on the surface of mobile sand, providing seed resources of blue algae, the pioneer colonization microorganisms in desert areas, can promote the formation of blue algae biocrust in sand, improve the soil properties of sand, make the surface biological community of sand enter a benign succession process, and ensure the accelerated evolution of desert biological community to grassland and shrub community stage.

[0024] In order to make the purpose, technical solution and advantages of the present utility model clearer, the implementation mode of the present utility model will be further described below in conjunction with the accompanying drawings.

[0025] Please refer to Figures 1 to 7 An embodiment of the utility model provides a mobile sand fixation device, which includes a plurality of fixed pile assemblies 1 and a plurality of connecting plates 2.

[0026] In this embodiment, the fixed pile components 1 are arranged in a "well"-shaped grid, and four connecting plates 2 are symmetrically arranged around each fixed pile component 1. Each fixed pile component 1 is detachably fixedly connected to adjacent sand-fixing components 1 through the four connecting plates 2 around it.

[0027] Each fixed pile assembly 1 includes a first cylinder 4, each first cylinder 4 is cylindrical in shape, and both ends thereof are open ends. Four grooves 8 are provided on the outer wall of the upper end of each first cylinder 4, and the grooves are evenly and symmetrically arranged on the corresponding first cylinder 4. The four connecting plates 2 around each fixed pile assembly 1 correspond to the four grooves 8 on the fixed pile assembly 1 one by one, and the two ends of each connecting plate 2 are respectively accommodated in the corresponding grooves 8 on the corresponding two fixed pile assemblies 1 and are detachably fixedly connected. Each connecting plate 2 is provided with a plurality of pore structures 3.

[0028] It should be noted here that, in this embodiment, the longitudinal cross-section of each connecting plate 2 may be a rectangle, for example Figure 1 It should also be noted that the longitudinal cross-sectional shape of each connecting plate 2 can also be approximately a single-peak normal distribution curve Figure 6 As shown, each connecting plate 2 has a porous structure, with an arc peak-shaped tip at the upper end and a smooth curved thick end at the lower end. This can reduce the accumulation of quicksand at the bottom of the connecting plate, reduce the speed at which the sand barrier is buried by wind and sand, and better play a role in sand fixation; but it should be noted that the shape of each connecting plate 2 in this embodiment is not limited by this embodiment, as long as it is reasonable.

[0029] Each connecting plate has a porous internal structure and can be immersed in cyanobacteria culture solution and pre-filled with desert cyanobacteria culture during the production stage. It can provide cyanobacteria germplasm resources in the sand fixation stage, provide the necessary microbial inoculum for the self-organized formation of cyanobacterial biocrust, and promote the positive succession process of desert biological communities.

[0030] Each fixed pile assembly 1 also includes a second cylinder 5, the upper end of each second cylinder 5 is detachably fixedly sleeved on the outer wall of the lower end of the corresponding first cylinder 4, and the axis of each first cylinder 4 coincides with the axis of the corresponding second cylinder 5; it should be noted here that the outer shape of each second cylinder 5 is funnel-shaped, with a small diameter at the upper end and a large diameter at the lower end.

[0031] A plurality of first channels 9 are provided in the wall of each first cylinder 4 around its axis, and a plurality of outwardly curved second channels 10 are provided in the wall of each second cylinder 5 around its axis. The first channels 9 in each first cylinder 4 correspond to the second channels 10 in the corresponding second cylinder 10 one by one and are interconnected.

[0032] A flexible rooting strip 6 is provided in each first channel 9. The lower end of each rooting strip 6 passes through the corresponding first channel 9 and the corresponding second channel 10 from top to bottom in sequence and then extends to the corresponding second cylinder 5. The upper end is located above the corresponding first cylinder 4. In this way, the lower ends of the corresponding rooting strips 6 can be dispersed and extended to the surroundings through the funnel shape of each second cylinder 5.

[0033] An end cover 7 is provided above each first cylinder 9. In the present embodiment, the outer shape of each end cover 7 is annular, and the axis of each end cover 7 coincides with the axis of the corresponding first cylinder 4. The upper ends of the rooting bars 6 in each first cylinder 4 are fixedly connected to the corresponding end cover 7, so that the corresponding rooting bars 6 can be pressed into the sand layer by pressing down the corresponding end cover 7 when needed. It should be noted here that each fixed pile assembly and connecting plate are made of biodegradable materials.

[0034] A disc 11 is provided inside each second cylinder 5, and a positioning rod 12 is provided at the lower end of each disc 11. The upper end of each positioning rod 12 is fixedly connected to the lower end surface of the corresponding disc 11, and the lower end is a pointed end. Each positioning rod 12 is used to facilitate fixing when installing the sand fixation component 1.

[0035] A sand fixation device in this example includes a method of use, which includes the following steps:

[0036] S1, assembling the device, then lifting up each of the end covers 7 to move up each of the rooting strips 6, and then burying each of the sand-fixing components 1 in the sand layer.

[0037] Specifically, first assemble the device as required, and then before burying the device in the soil layer to be fixed, lift each end cover to move each rooting bar 6 upward, so that the lower end of each rooting bar 6 is retracted to the inside of the corresponding second cylinder 5, and then bury the device in the sand layer. When burying the device, it can be relatively fixed by each positioning rod 12 to facilitate burying.

[0038] S2. After each of the sand-fixing components 1 is buried, each of the end covers 7 is pressed downward to allow each of the rooting bars 6 to move into the sand layer through the corresponding first channel 9 and the corresponding second channel 10, and then take root in the sand layer.

[0039] Specifically, after the device is buried, each end cover 7 is squeezed downward to allow each rooting strip 6 to move into the sand layer through the corresponding first channel 9 and the corresponding second channel 10. Since the shape of each second cylinder 5 is funnel-shaped, the rooting strips entering the sand layer can be spread out, thereby enhancing the sand fixation effect.
