Description

Technical Field

[0001] This application relates to the field of slope treatment technology, and in particular to a fixing device for a planting cell. Background Technology

[0002] Mining and road construction activities create large areas of bare rock slopes and platforms. These bare rocks not only affect the aesthetics of the environment, but also cause secondary geological hazards as they break down. In windy weather, the dust formed from weathering is carried by the wind and pollutes the atmosphere. Therefore, the treatment of bare rock slopes is essential.

[0003] Planting geocells has been promoted and applied in my country for more than ten years, achieving good engineering results. Planting grass in geocells has been particularly effective in bare rock projects such as mine ecological restoration and highway and railway slopes.

[0004] A vegetated grid is essentially a honeycomb-like three-dimensional system, constructed from long strips of plastic sheets connected by methods such as ultrasonic welding. When unfolded, it forms a honeycomb-like three-dimensional mesh. The width of the long strips determines the height of the grid. It can significantly improve the performance of ordinary infill materials in load-bearing and insect control applications over a large area, thereby reshaping the vegetation growth environment. Its main principle involves setting up vegetated grid mesh strips on bare rock slopes, fixing the mesh by driving steel rods into the bedrock, covering the grids with soil, and planting vegetation—a method of greening exposed platforms and slopes.

[0005] Traditional methods of fixing vegetated geocells primarily involve vertically driving threaded steel bars of a specific grade into the bedrock. Depending on geological conditions, the driving depth is typically 1-2 meters, with the steel bars spaced 1-2 meters apart. The exposed portion of the anchor bolts is secured using a lug-type anchor. The disadvantages of this method are the small contact area between the steel bars and the geocell. While this is acceptable for slopes less than 45 degrees, as the slope increases, the pressure from the internal backfill significantly increases, leading to poor fixation on slopes greater than 45 degrees. Furthermore, traditional steel bars are easily damaged by wind, rain, and minor geological movements, potentially causing slippage in the entire geocell area. Additionally, the lack of a rust-proof layer on the surface of traditional steel bars makes them susceptible to corrosion under the influence of groundwater, reducing the fixing effectiveness. Based on these considerations, this application explores certain improvements to this method. Utility Model Content

[0047] The present application will be further described in detail below with reference to the accompanying drawings.

[0048] The vegetation grid 1 is approximately rhomboid in shape. The fixing device 2 is an anchor rod 21 with a sharp end 211 at one end and a blunt end 212 at the other end. During fixing, the sharp end 211 is embedded into the geological base layer 3 by hammering the blunt end 212 of the anchor rod 21. The part of the anchor rod 21 protrudes outside the ground, and the vegetation grid 1 is fixed by the part of the anchor rod 21 that protrudes from the ground.

[0049] refer to Figure 1 A large, continuous area of ​​plant-covered greenhouses is set up. (See attached reference) Figure 2-3The vegetation grid 1 is laid on the ground, one end of the fixing device 2 is embedded in the geological base layer 3, and the other end is fixed to the vegetation grid 1, and vegetation is planted in the vegetation grid 1.

[0050] Example 1

[0051] This application discloses a fixing device for a growing greenhouse.

[0052] Reference Figure 4-5 In this embodiment, the fixing device for the vegetation grid 1 includes an anchor rod 21 and a support member 22. The support member 22 has an arc-shaped plate structure with a certain width. The outer wall of the arc-shaped plate structure can be used to support the inner wall of the vegetation grid 1. In use, the contact surface between the outer wall of the arc-shaped plate structure and the inner wall of the vegetation grid 1 is the support surface. The anchor rod 21 includes a rod portion, one end of which is a sharp end 211 and the other end is a blunt end 212. In use, the sharp end 211 is embedded into the interior of the geological base layer 3. The arc-shaped plate structure of the support member 22 is fixed to the blunt end 212 of the anchor rod 21, and the blunt end 212 of the anchor rod 21 is fixed to the side of the support member 22 away from the support surface. Because the support member 22 in this application has an arc-shaped plate structure with a certain width, it has a large contact area with the inner wall of the vegetation grid 1, thereby improving the support effect. In order to improve corrosion resistance, the surfaces of the anchor rod 21 and the support member 22 have an anti-corrosion layer. In this embodiment, the unit is fixed within the cell and supported within the cell.

[0053] In this specific implementation, the anchor bolt 21 can be made of steel rod, and the support 22 can be made of curved steel plate, which are assembled by welding the curved steel plate with steel rod. The curved steel plate and steel rod are treated with hot-dip galvanizing to improve their rust prevention effect. Hot-dip galvanizing increases rust resistance and extends service life. In practice, the width of the curved steel plate is generally 10-50cm, the diameter is generally 5-15cm, and the depth of the steel rod driven into the bedrock is 50-100cm, depending on the actual situation.

[0054] In this embodiment, the fixing of the arc-shaped steel plate to the vegetation grid 1 increases the contact area, reduces the pressure on the grid, and can effectively fix the grid, making the fixing of the vegetation grid 1 more secure. This allows the vegetation grid 1 to adapt to steeper slopes, effectively improves the hanging stability of the vegetation grid 1, increases the service life of the vegetation grid 1, and significantly reduces the frequency and cost of maintenance and repair.

[0055] In this embodiment, the improvements to most commercially available vegetation grids 1 are applicable, effectively improving the installation stability of the vegetation grids 1, and are tested to be suitable for steep slopes of 45-60 degrees. Through further improvements, the vegetation grids 1 can be applied to even steeper slopes, enhancing the revegetation effect on high slopes, and are suitable for ecological restoration and roadside slope reinforcement.

[0057] This application discloses a fixing device for a growing greenhouse.

[0058] refer to Figure 6 In this embodiment, the inside of the support member 22 is fixedly connected to two anchor members 21. It is known that the fixing effect of the fixing device 2 can be improved by setting more anchor members 21.

[0059] Example 3

The blunt end 212 of the anchor member 21 is fixed to the side of the support member 22 away from the support surface via the connecting parts 214.

[0062] In the aforementioned embodiments, during installation, the anchor bolt 21 can only be embedded into the geological base layer 3 close to the inner wall of the vegetation grid 1. However, in actual implementation, the geological base layer 3 corresponding to the inner wall of the vegetation grid 1 may not be suitable for fixing the anchor bolt 21, such as soft soil or hard rocks. By setting a connecting part 214 to connect with the anchor bolt 21, the embedding position of the anchor bolt 21 can be adapted. Of course, multiple anchor bolts 21 can also be set, with each anchor bolt 21 having a different number of connecting parts 214. In this embodiment, the anchor bolt is fixed and supported within the grid.

[0063] refer to Figure 7 In this embodiment, the support member 22 is provided with a flange 221, which is disposed on one side of the support surface of the support member 22. The flange 221 can constrain the outer edge of the planted grid 1, thereby further improving the stability of the planted grid 1 after fixation. Of course, this flange 221 can also be provided in other embodiments, achieving the same effect.

That is, the blunt end 212 of the anchor member 21 is fixed to the side of the support member 22 near the support surface via the connecting portion 214. Through this embodiment, the anchor member 21 can be fixed in the first vegetated grid chamber 1, while the support member 22 is set in the adjacent vegetated grid chamber 1. The connecting portion 214 spans across the wall of the vegetated grid chamber 1, thereby realizing cross-grid support, that is, fixed within the current grid and supported in the adjacent grid.

This shape better adapts to the space of the vegetation grid 1, allowing the support member 22 to provide more adequate support within the vegetation grid 1 and to abut against the inner walls, further improving support stability. Of course, the support member 22 can also be configured with various other shapes that are beneficial to improving support stability. In addition, the use of specially shaped supports also facilitates the formation of different overall shapes of the vegetation grid 1, which is beneficial for the design of the slope protected by the vegetation grid 1.

The anchor member 21 is connected to the other two hexagonal shapes through the connecting part 214. In use, by fixing one anchor member 21, the three hexagonal shapes are placed in the grids of three adjacent vegetation cells 1. The sidewalls of the support members 22 of the hexagonal shapes abut against the inner wall of the grid of the vegetation cell 1, and the connecting part 214 spans across the inner wall side of the vegetation cell 1, thereby further improving the support effect and efficiency. That is, the blunt end 212 of one anchor member 21 is fixedly connected to multiple support members 22 through the connecting part 214, thereby achieving the effect of cross-grid support.

[0075] refer to Figure 11-13In this embodiment, to improve the stability of the anchor bolt 21 after it is embedded in the geological base layer 3, an anti-slip structure 213 is constructed on the outer wall of the bolt portion of the anchor bolt 21. Figure 12 In the middle, the entire outer wall of the anchor bolt 21 is roughened to form a frosted layer. Figure 13 In Figure 14, a roughened frosted layer is provided at intervals on the outer wall of the anchor bolt 21. Threads are also provided on the outer wall of the anchor bolt 21.
