Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mine restoration technology, specifically a geocell composite structure for mine restoration. Background Technology
[0002] Ecological restoration of mines is a crucial aspect of mine environmental management. Traditional methods primarily utilize concrete slope protection structures, which, while providing some structural stability, lack ecological restoration capabilities and struggle to achieve long-term stable vegetation growth. Current slope protection methods suffer from the following problems: 1. Low vegetation survival rate: simple planting soil is easily washed away by rainwater, and seeds are difficult to anchor; 2. Poor drainage: waterlogging during the rainy season easily leads to vegetation death; 3. Unstable anchoring systems: prone to sliding or detachment on the slope. To address these issues, a composite structure is proposed that provides both structural stability and ensures long-term vegetation survival, thereby achieving better ecological restoration of mines. Utility Model Content
[0003] To address the above problems, this utility model provides a geocell composite structure for mine restoration, which solves the problems of poor drainage and difficulty in vegetation survival in mine restoration structures.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A geocell composite structure for mine remediation includes: a geocell body and anchors;
[0006] The geogrid body has a grid structure, a drainage structure at its bottom, and anchoring points on the geogrid body.
[0007] The anchor passes through the anchor point and is fixed to the ground, so that the geogrid body fits the ground.
[0008] The geogrid body has a grid with a space for supporting plant growth.
[0009] As a further improvement to the above solution, the accommodating space is provided with an internal vegetation strip, which has a layered structure.
[0010] As a further improvement to the above solution, the built-in vegetation strip includes a seed carrier layer and a functional material layer, wherein the functional material layer contains a water-retaining agent and / or a slow-release fertilizer.
[0011] As a further improvement to the above solution, the built-in vegetation strip also includes:
[0012] The upper isolation layer is located above the seed carrier layer;
[0013] The lower isolation layer is located below the functional material layer and is in contact with the bottom of the geogrid body;
[0014] The lower isolation layer is permeable, allowing the drainage structure to drain normally.
[0015] As a further improvement to the above scheme, the drainage structure is an array of slots opened at the bottom of the geogrid body.
[0016] As a further improvement to the above scheme, the anchoring point includes a reinforcing strip disposed on the inner side of the geogrid body, and the reinforcing strip has perforations for easy anchoring.
[0017] As a further improvement to the above solution, the anchor includes an anchor rod that passes through a perforation and is anchored to the ground surface. The anchor rod is fitted with a connecting piece that splices and fixes multiple geogrid bodies together. The anchor rod is also provided with a fastening bolt that presses the connecting piece against the surface of the geogrid body.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. By setting up a containment space within the geogrid body in this scheme, a stable growth environment can be provided for plant seeds, ensuring normal plant growth and thus improving the effect of ecological restoration. Multiple drainage structures are set on the geogrid body to facilitate drainage, thereby reducing the impact on the seeds within the containment space and providing a better environment for plant seed growth. Anchors can be used to fix multiple geogrid bodies to the ground and to splice multiple geogrid bodies, ensuring the stability of the overall structure.
[0020] 2. By setting up an internal vegetation strip within the containment space, and by setting up functional material layers, upper isolation layers, and lower isolation layers, the seeds can be restrained, and at the same time, sufficient nutrients can be provided for seed growth.
[0021] 3. Anchor points are set on the geogrid body, which can provide a good anchoring point for a single geogrid body, or multiple geogrid bodies can be combined to achieve joint anchoring of multiple geogrid bodies, which can further improve the stability of the geogrid body for surface restraint support.

[0028] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0029] like Figure 1-5 As shown, the specific solution of this embodiment is: a geocell composite structure for mine remediation, comprising: a geocell body 1 and anchors 2; the geocell body 1 has a grid structure, specifically, the geocell body 1 is formed by welding high-density polyethylene sheets to form a honeycomb structure, the sheet thickness is 2mm, the grid side length is 200mm, and a drainage structure 101 is provided at the bottom of the geocell body 1. Specifically, in this embodiment, the drainage structure 101 is an array of slots opened at the bottom of the geocell body 1, as shown in the attached diagram. Figure 4 As shown, the drainage structure 101 facilitates the drainage of water from the geogrid body 1, thereby reducing the erosion of plant seeds and providing a better seed growth environment inside the geogrid body 1.
[0030] Anchor points 102 are provided on the geogrid body 1, as shown in the attached document. Figure 4 As shown, anchor point 102 includes a reinforcing strip disposed inside the geogrid body 1. The reinforcing strip has perforations for easy anchoring. The reinforcing strip is disposed at the corner of the geogrid body 1, which effectively strengthens the geogrid body 1. Anchor 2 passes through anchor point 102 and is fixed to the ground, so that the geogrid body 1 is in contact with the ground. The structure of anchor 2 is shown in Appendix. Figure 2As shown, the anchor 2 includes an anchor rod 201, which passes through a perforation and is anchored to the ground surface. To enhance the stability between the anchor rod 201 and the ground surface, multiple barbs can be provided on the surface of the anchor rod 201 to prevent it from being pulled out at will. A connecting piece 202 is sleeved on the anchor rod 201 to fix multiple geogrid bodies 1 together. The anchor rod 201 is also provided with a fastening bolt 203 to tighten the connecting piece 202 to the surface of the geogrid body 1. Through the anchor 2, on the one hand, the individual geogrid body 1 can be firmly fixed to the ground surface, and on the other hand, multiple geogrid bodies 1 can be tightly spliced together, thereby improving the overall stability.
[0031] The geogrid body 1 has a grid within it that provides space 3 for supporting plant growth. Specifically, the grid within the geogrid body 1 is made of wire or similar materials. The space 3 is arranged on the grid but does not completely cover it; rather, it is arranged intermittently. The grid provides attachment points for the arrangement of the space 3.
[0032] like Figure 3 As shown, the containment space 3 is equipped with an internal vegetation strip 301, which has a layered structure. Specifically, the internal vegetation strip 301 includes a seed carrier layer 302 and a functional material layer 303. The functional material layer 303 contains a water-retaining agent and / or slow-release fertilizer. The internal vegetation strip 301 also includes an upper isolation layer 304 located above the seed carrier layer 302 and a lower isolation layer 305 located below the functional material layer 303, which is in contact with the bottom of the geogrid body 1. The lower isolation layer 305 is permeable, allowing the drainage structure 101 to drain normally. Both the upper isolation layer 304 and the lower isolation layer 305 are made of biodegradable materials and will automatically degrade after at least a period of use to facilitate seed growth.
