Abstract
Description
Technical Field
[0001] This utility model relates to the field of ecological restoration technology, and more specifically, to an ecological restoration structure for damaged mountain slopes. Background Technology
[0002] As mining activities continue, numerous ecological problems remain after mining operations cease. Among these, steep slope breaches created by mine slope collapses not only affect the stability of the terrain but also severely damage the surrounding ecosystem. These breaches typically have steep gradients, poor soil, and difficulty in natural vegetation recovery. They also easily trigger secondary geological disasters such as soil erosion and landslides, threatening the lives and property of nearby residents. Traditional ecological restoration methods for such steep slope breaches suffer from poor restoration results, high construction difficulty, and high costs.
[0003] Traditional slope restoration methods typically involve vegetation restoration (planting grass and trees), engineering protection (mortar-grouted rubble slope protection, concrete slope protection, and anchor bolt support), or a combination of both. However, the slopes of damaged mountains are often steep, making direct vegetation restoration or engineering protection difficult and prone to soil erosion and landslides. Utility Model Content
[0004] To overcome the shortcomings mentioned above, this utility model aims to provide an ecological restoration structure for damaged mountain slopes. Through the construction of steps and slope reinforcement, the slope is decomposed into multiple relatively gentle steps, reducing the overall slope and effectively reducing the risk of soil erosion and landslides.
[0005] An ecological restoration structure for a damaged mountain slope includes a wire mesh fixed to the damaged mountain. Planting troughs are laid sequentially from bottom to top on the wire mesh. A rod is fixed to the lower end of each planting trough and inserted into the wire mesh. Concrete is poured between the damaged mountain, the wire mesh, and the planting troughs. A stepped trench is excavated on the slope of the damaged mountain. A partition is fixed inside the planting trough, dividing the planting trough into a planting chamber and a drainage chamber. Water passage holes are provided on the partition, and drainage holes are provided at the bottom of the drainage chamber. Holes adapted to the drainage holes are provided on the partition.
[0006] Furthermore, the stepped groove is filled with gravel.
[0007] Furthermore, a drainage ditch is provided at the bottom of the damaged mountain, and a drainage pipe is integrally formed in the drainage ditch, with one end of the drainage pipe connected to the drainage hole at the bottom of the lowest drainage chamber.
[0008] Furthermore, a central pipe is installed inside the drainage blind ditch, and the drainage pipe is connected to the central pipe.
[0009] Furthermore, the concrete is C20 concrete.
[0010] Furthermore, the mesh size of the wire mesh is 8cm × 8cm.
[0011] Furthermore, filter screens are fixedly connected to both the water passage hole and the drain hole.
[0012] Furthermore, the filter screen is a geotextile filter screen.
[0013] Furthermore, a slot is provided on the lower end face of the planting trough, and a first locking block adapted to the slot is fixedly connected to the drainage blind ditch.
[0014] Furthermore, both the planting chamber and the partition are fixedly connected with a second card block adapted to the card slot.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In this invention, stepped trenches are excavated sequentially on the slope of a damaged mountain through blasting or mechanical excavation. This helps to spray more concrete between the slope and the planting trench, while increasing the thickness of the protective layer and improving the stability of the slope. The stepped trenches can decompose the slope into multiple relatively gentle steps, reducing the overall slope of the slope and effectively reducing the risk of soil erosion and landslides.

[0023] 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. Specific implementation examples:
[0025] like Figure 1-4 As shown, an ecological restoration structure for a damaged mountain slope includes a wire mesh 2 fixed to the damaged mountain slope 1 by anchor bolts. Planting troughs 3 are erected sequentially from bottom to top on the wire mesh 2. Inserted rods 31 are fixedly connected to the lower end of the planting troughs 3 and inserted into the wire mesh 2. Concrete 4 is poured between the damaged mountain slope 1, the wire mesh 2, and the planting troughs 3. After the concrete 4 dries, the planting troughs 3 are fixed to the damaged mountain slope 1. Gabion cages 16 are installed in the damaged area of the damaged mountain slope 1. The gabion cages 16 and the damaged area are covered with soil 17. The planting troughs 3, wire mesh 2, and planting troughs 3 (with inserted rods 31) are then connected to the wire mesh 2. Concrete 4 is sprayed between poles 31 to form a solid protective layer, enhancing the weathering and erosion resistance of the damaged mountain slope 1. Stepped trenches 5 are excavated sequentially on the slope of the damaged mountain 1 by blasting or mechanical excavation (before stacking gabion cages 16 and covering soil 17). This helps to spray more concrete between the slope and planting trenches 3, while increasing the thickness of the protective layer and improving the stability of the slope. The stepped trenches 5 can decompose the slope into multiple relatively gentle steps, reducing the overall slope of the slope and effectively reducing the risk of soil erosion and landslides.
[0026] like Figure 1-4 As shown, between the laying of wire mesh 2, some of the gravel generated during the excavation of stepped trench 5 is filled into the stepped trench 5. The height of the gravel is lower than the height of each step trench 5. Then the wire mesh 2 is laid. By filling the space between the wire mesh 2 and the stepped trench 5 with gravel, it is convenient to insert the fixing rod 31.
[0027] like Figure 1-4As shown, a partition 32 is fixedly connected inside the planting trough 3. The partition 32 divides the inside of the planting trough 3 into a planting chamber 33 and a drainage chamber 34. The planting chamber 33 is filled with planting soil 6 for cultivating plants. A water passage hole 35 is opened on the partition 32 so that rainwater in the planting chamber 33 can flow into the drainage chamber 34. A drainage hole 36 is opened at the bottom of the drainage chamber 34. The partition 32 is inverted L-shaped and has holes on the partition 32 that are adapted to the position and size of the drainage hole 36 so that rainwater in the upper drainage chamber 34 can be discharged into the lower drainage chamber 34 through each drainage hole 36.
[0028] like Figure 1-4 As shown, a drainage ditch 7 is set at the bottom of the damaged mountain body 1. A drainage pipe 8 is integrally cast in one side of the drainage ditch 7. One end of the drainage pipe 8 is connected to the drainage hole 36 at the bottom of the lowest drainage chamber 34. A central pipe 9 is set in the drainage ditch 7. The central pipe 9 is connected to the external drainage channel or to the river. All drainage pipes 8 are connected to the central pipe 9, so that excess rainwater in the planting trough 3 can be discharged into the central pipe 9 and flow into the external drainage channel or river.
[0029] like Figure 1-4 As shown, based on the local climate, soil conditions and ecological environment characteristics, native plant varieties suitable for growing on steep slopes, such as drought-resistant and barren-tolerant herbaceous plants, are selected and planted in planting compartment 33.
[0030] like Figure 1-4 As shown, concrete 4 is C20 concrete, and the mesh size of wire mesh 2 is 8cm×8cm. After laying wire mesh 2 on the damaged mountain 1, some concrete 4 can be sprayed on wire mesh 2. Before concrete 4 dries, the insertion rod 31 on the planting trough 3 is inserted into wire mesh 2 and gravel.
[0031] like Figure 1-4 As shown, filter screens 10 are fixedly connected inside both the water passage hole 35 and the drainage hole 36. The filter screen 10 is a geotextile filter screen, which uses its pore structure to allow fluids such as water to pass through while blocking soil particles.
[0032] like Figure 1-4 As shown, a slot 37 is provided on the lower end face of the planting trough 3. A first locking block 11 adapted to the slot 37 is fixedly connected to the drainage blind ditch 7. When setting up the lowermost planting trough 3, after inserting the rod 31 into the wire mesh 2, the planting trough 3 is moved so that the slot 37 on the planting trough 3 can be fitted onto the first locking block 11, which plays a positioning role and makes the planting trough 3 more neatly arranged.
[0033] like Figure 1-4As shown, both the planting trough 33 and the partition 32 are fixedly connected with second locking blocks 12 that are adapted to the locking slots 37. When the planting troughs 3 are erected sequentially from bottom to top, they are moved and adjusted so that the locking slots 37 on the upper planting trough 3 are fitted onto the second locking blocks 12 on the lower planting trough 3, so that the planting troughs 3 in the same row are arranged neatly.
[0034] like Figure 1-4 As shown, a cover plate 13 is provided on the uppermost planting trough 3. The cover plate 13 has a slot 14 that fits the second slot 12. After the concrete 4 is poured, the cover plate 13 is placed on the uppermost planting trough 3 and the slot 14 is fitted onto the second slot 12 to serve as a positioning function. The cover plate 13 is fixed to the damaged mountain 1 by expansion bolts 15. The cover plate 13 is used to seal the gap between the planting trough 3 and the damaged mountain 1 to prevent rainwater from flowing directly into the gap left between the damaged mountain 1 and the planting trough 3.
[0035] The planting trough 3 has holes on both sides for use with ropes and cranes to lift the planting trough 3, making it easy to install without manual handling; the drainage ditch 7 is also filled with planting soil 6, in which climbing plants are planted.
[0036] The working principle of the ecological restoration structure for a damaged mountain slope in this embodiment is as follows: First, the slope of the damaged mountain 1 is excavated by blasting or mechanical excavation to sequentially create stepped trenches 5. The excavated gravel is placed inside gabion cages 16, and the gabion cages 16 are stacked in the damaged area of the damaged mountain 1. Covering soil 17 is then filled onto the gabion cages 16 and compacted so that the surface of the covering soil 17 has the same stepped shape as the stepped trenches 5. Next, wire mesh 2 is laid. Between the wire mesh 2 sections, some of the gravel generated during the excavation of the stepped trenches 5 is filled into the stepped trenches 5, with the height of the gravel lower than the height of each step of the stepped trench 5. Next, wire mesh 2 is laid. By filling the space between wire mesh 2 and stepped groove 5 with gravel, it is easy to insert fixing rods 31. After laying wire mesh 2 on the damaged mountain 1, some concrete 4 can be sprayed on wire mesh 2. Before the concrete 4 dries, the fixing rods 31 on the planting trough 3 are inserted into the wire mesh 2 and gravel. More concrete is sprayed between the slope and the planting trough 3 to increase the thickness of the protective layer and improve the stability of the slope. The stepped groove 5 and the gabion stone cages 16 and stepped soil cover 17 can decompose the slope into multiple relatively gentle steps, reduce the overall slope of the slope, and effectively reduce the risk of soil erosion and landslides.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
