Description

Technical Field

[0001] This utility model relates to the field of tailings dam technology, specifically a flood control and reinforcement structure for tailings dams. Background Technology

[0002] Tailings dams are constructed by damming valleys or enclosing land to store tailings or other industrial waste discharged after ore beneficiation in metal or non-metal mines. Tailings dams are man-made debris flow hazards with high potential energy and are prone to collapse. Once they fail, they can easily cause major accidents. Therefore, it is necessary to lay geomembranes for flood control and soil erosion prevention.

[0003] Chinese patent application number 202221350499.5 discloses a slope structure for an iron ore tailings dam, including a reinforcing plate assembly, a waterproof groove provided inside the reinforcing plate assembly, a geomembrane provided inside the waterproof groove, an embedded part fixedly installed at the bottom end of the reinforcing plate assembly, and an installation groove provided at the top end of the embedded part.

[0004] The patented reinforcement plate assembly cannot be adjusted according to needs, making it impossible to adjust the installation of the reinforcement structure according to different slopes during use. Furthermore, the reinforcement structure occupies a large space when not in use or during transportation, resulting in poor practical performance of the reinforcement structure.

[0005] Meanwhile, this patent only fixes the reinforcement structure by inserting fasteners into the soil, which makes the reinforcement structure relatively unstable after installation. It is prone to loosening and failure, resulting in poor stability of the reinforcement structure. Utility Model Content

[0006] To address the above problems, this utility model provides a flood control and reinforcement structure for tailings ponds, which solves the aforementioned issues.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flood control and reinforcement structure for tailings dams, comprising a geomembrane and two reinforcement plates disposed on one side of the geomembrane, a fixing frame provided at one end of the two reinforcement plates, two connecting rods connected to one side of the fixing frame, and the exterior of the two connecting rods respectively rotatably connected to one end of the two reinforcement plates;

[0008] Each of the two reinforcing plates has a mounting plate at one end, and a fixed shaft is connected to one side of the mounting plate. The outside of the fixed shaft is rotatably connected to the inside of the reinforcing plate.

[0009] A fastening mechanism is installed on one side of the mounting plate. The fastening mechanism includes an insert, the bottom of which is pyramidal. A limit ring is connected to the outside of the insert, and a cavity is opened inside the insert.

[0010] Preferably, two movable frames are connected in the cavity, one side of each movable frame is provided with an inclined surface, and one side of each movable frame is connected with a reinforcing rod, the outside of which is slidably connected to the inside of the embedded part.

[0011] Preferably, the upper end of the insert has an opening, and a plug is inserted into the opening, one end of which is pyramidal.

[0012] Preferably, a connecting plate is connected to one side of the insert block, and the connecting plate is connected and installed to the insert by bolts.

[0013] Preferably, the fixing frame is internally threaded with a fixing screw, one end of the fixing screw is connected to a rotating block, the other end of the fixing screw is connected to a fixing plate, and the two sides of the fixing plate are slidably connected to the inner side of the fixing frame.

[0014] Preferably, one end of each of the two reinforcing plates has a mating surface, and the mating surface of the reinforcing plate abuts against the bottom of the fixing plate when the reinforcing plate is stored.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This application uses a combination of a fixed frame, a fixed plate, and a reinforcing plate, and the reinforcing plate is combined with the mounting plate, so that the reinforcing structure can be easily folded and stored when not in use, which facilitates transportation. When in use, the reinforcing structure can be unfolded and the mounting plate can be adjusted and installed according to different tailings dam slopes. This solves the problem that the reinforcing structure occupies a lot of space when not in use and during transportation, and that it cannot be adjusted and installed according to different slopes when in use, which helps to improve the practical performance of the reinforcing structure.

[0017] 2. This application uses an embedding mechanism to embed the reinforced structure into the ground during installation, and uses reinforcing rods to cooperate with the embedded parts for fixation. This solves the problem that the reinforced structure is not very firm after installation and is prone to loosening, which leads to the failure of the reinforced structure. It is beneficial to improve the firmness of the reinforced structure after installation. Attached Figure Description

Detailed Implementation

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] Please see Figures 1 to 8 A flood control and reinforcement structure for tailings dams includes a geomembrane 1 and two reinforcement plates 2 installed on one side of the geomembrane 1. One end of each reinforcement plate 2 is equipped with a fixing frame 4, and one side of the fixing frame 4 is connected to two connecting rods 5. The exterior of each connecting rod 5 is rotatably connected to one end of the two reinforcement plates 2. Tailings dam slopes often require seepage prevention structures. Currently, there are two methods: one is direct shotcreting, which is difficult and prone to concrete waste; the other is laying the geomembrane 1. The geomembrane 1 is a seepage prevention material made from high-molecular polymers. When laid on the surface of the tailings dam, the geomembrane 1 can prevent seepage, lower the phreatic line of the dam. An excessively high phreatic line will saturate the soil of the dam, reducing shear strength and easily leading to accidents such as dam slope landslides. By laying the geomembrane, the impact of seepage on the dam can be reduced, enhancing the stability of the dam and ensuring the safe operation of the tailings dam.

[0029] Each of the two reinforcing plates 2 has a mounting plate 9 at one end, and a fixing shaft 10 is connected to one side of the mounting plate 9. The outside of the fixing shaft 10 is rotatably connected to the inside of the reinforcing plate 2.

[0030] When the reinforcement structure is in use, the personnel unfold the two reinforcement plates 2 and lay them on the slope of the tailings dam. Then, the fixing plate 8 in the fixing frame 4 is lowered to abut against one side of the two reinforcement plates 2. At this time, the fixing plate 8 restricts the installation of the two reinforcement plates.

[0031] Specifically, the bottom of the two reinforcing plates 2 is restricted by the slope and will not deflect, and the top of them is also restricted by the fixing plate 8 and will not deflect. Therefore, the two reinforcing plates 2 can remain stable on the tailings dam body at this time.

[0032] Next, the mounting plates 9 are adjusted. Specifically, regardless of the slope of the reinforcing plate 2, both mounting plates 9 can be rotated and adjusted at one end of the reinforcing plate 2. The fixed shafts 10 on the two mounting plates 9 will rotate inside the reinforcing plate 2 to adjust the angle, so that the reinforcing structure can be applied to different slopes. Then, the personnel insert the embedded part 12 into the ground using tools.

[0033] An embedding mechanism 11 is installed on one side of the mounting plate 9. The embedding mechanism 11 includes an insert 12. The bottom of the insert 12 is pyramidal. A limit ring 13 is connected to the outside of the insert 12. A cavity 14 is opened inside the insert 12.

[0034] Two movable frames 15 are connected in the cavity 14. One side of each movable frame 15 has an inclined surface. One side of each movable frame 15 is connected to a reinforcing rod 16. The outside of the reinforcing rod 16 is slidably connected to the inside of the embedded part 12.

[0035] Personnel insert the embedded part 12 through the mounting plate 9 into the ground. Specifically, the embedded part 12 is hammered into the ground using a tool. It should be noted that the embedded part 12 is inserted until the limiting ring 13 abuts against the mounting plate 9. In this way, the embedded part 12 can not only fix the mounting plate 9 in the horizontal direction, but also in the vertical direction.

[0036] After the embedded part 12 is inserted into the ground, the personnel insert the insert block 18 into the insertion port 17 on the embedded part 12. When the insert block 18 is inserted, as the insert block 18 goes deeper, it will push open the two moving frames 15, so that the two moving frames 15 move synchronously to both sides of the embedded part 12. At this time, the movement of the moving frames 15 in the cavity 14 will drive the reinforcing rod 16 to move inside the embedded part 12, and the reinforcing rod 16 will also be inserted into the ground on both sides, thereby improving the firmness of the embedded mechanism 11 and thus improving the firmness of the reinforcement structure.

[0037] After the reinforcing rod 16 is inserted into the soil, it significantly increases the contact area between the embedded part 12 and the soil. Compared with simply inserting the fixing part into the soil, the reinforcing rod 16 provides more surface for interaction with the soil, which increases the friction and embedding force of the soil on the structure, thereby improving the anchoring effect of the structure in the soil. In addition, the reinforcing rod 16 grips the surrounding soil like an anchor claw. When the embedded part 12 tries to loosen and detach from the soil, the reinforcing rod 16 will be resisted by the soil, preventing it from being pulled out. Therefore, the strength of the reinforced structure can be improved.

[0038] It should be further added that after the insert 18 is inserted into the embedded part 12, the connecting plate 19 will also abut against one side of the embedded part 12. At this time, the personnel will connect and install the connecting plate 19 and the embedded part 12 with bolts so that the insert 18 and the embedded part 12 are connected and fixed to prevent the insert 18 from loosening.

[0039] When it is necessary to disassemble the embedded mechanism 11, the personnel take out the insert block 18, and then use tools such as a pry bar to reset the moving frame 15 through the insertion port 17. Finally, the embedded part 12 can be easily removed.

[0040] The upper end of the insert 12 is provided with an insertion port 17, and an insertion block 18 is inserted into the insertion port 17. One end of the insertion block 18 is pyramidal. The pyramidal shape of the insertion block 18 is mainly to cooperate with the inclined surface on the movable frame 15, so that when the insertion block 18 is inserted, it will smoothly push the two movable frames 15 apart.

[0041] A connecting plate 19 is connected to one side of the insert 18, and the connecting plate 19 is connected and installed to the embedded part 12 by bolts.

[0042] The fixing frame 4 has a fixing screw 6 connected to its internal thread. One end of the fixing screw 6 is connected to a rotating block 7, and the other end of the fixing screw 6 is connected to a fixing plate 8. The two sides of the fixing plate 8 are slidably connected to the inner side of the fixing frame 4.

[0043] One end of each of the two reinforcing plates 2 has a mating surface 3. When the reinforcing plates 2 are stored, the mating surface 3 abuts against the bottom of the fixed plate 8. When the reinforcing structure is not in use and is stored, the two reinforcing plates 2 rotate together on the connecting rod 5 inside the fixed frame 4. Both reinforcing plates 2 are rotated and adjusted towards the center. At this time, the mating surface 3 of the reinforcing plates 2 will be parallel to the fixed plate 8. Then, the operator rotates the rotating block 7 to make the fixing screw 6 rotate and descend inside the fixed frame 4, thereby driving the fixed plate 8 to descend to the point where it abuts against the mating surface 3 of the reinforcing plates 2.

[0044] It should be further explained that the bottom surface of the fixing plate 8 cooperates with the mating surface 3 of the reinforcing plate 2 to restrict the reinforcing plate 2, so that the two reinforcing plates 2 will not loosen after being folded and stored side by side;

[0045] Because if the reinforcing plate 2 becomes loose or rotates, the mating surface 3 is restricted by the reinforcing plate 2, preventing the reinforcing plate 2 from rotating. Therefore, the reinforcing plate 2 can be fixed and restricted after being stored.

[0046] When using this utility model:

[0047] First, when the reinforcement structure is in use, the personnel unfold the two reinforcement plates 2 and lay them on the slope of the tailings dam. Then, the fixing plate 8 in the fixing frame 4 is lowered to abut against one side of the two reinforcement plates 2. At this time, the fixing plate 8 restricts the installation of the two reinforcement plates.

[0048] Secondly, the mounting plates 9 are adjusted. Specifically, regardless of the slope of the reinforcing plate 2, the two mounting plates 9 can be rotated and adjusted at one end of the reinforcing plate 2. The fixed shafts 10 on the two mounting plates 9 will rotate inside the reinforcing plate 2 to adjust the angle, so that the reinforcement structure can be applied to different slopes.

[0049] Then, the personnel insert the embedded part 12 through the mounting plate 9 into the ground. Specifically, the embedded part 12 is hammered into the ground using a tool. It should be noted that the embedded part 12 is inserted until the limiting ring 13 abuts against the mounting plate 9. In this way, the embedded part 12 can fix the mounting plate 9 not only horizontally but also vertically. After the embedded part 12 is inserted into the ground, the personnel insert the insert block 18 into the insertion port 17 on the embedded part 12. When the insert block 18 is inserted, as the insert block 18 goes deeper, it will push open the two moving frames 15, so that the two moving frames 15 move synchronously to both sides of the embedded part 12. At this time, the movement of the moving frames 15 in the cavity 14 will drive the reinforcing rod 16 to move inside the embedded part 12, and the reinforcing rod 16 will also be inserted into the ground to both sides, thereby improving the firmness of the embedded mechanism 11 and thus improving the firmness of the reinforcement structure.

[0050] Finally, when it is necessary to disassemble the embedded mechanism 11, the personnel take out the insert block 18, and then use tools such as a pry bar to reset the moving frame 15 through the insertion port 17. Finally, the embedded part 12 can be easily taken out. Moreover, when the reinforcement structure is not in use and is stored, the two reinforcement plates 2 rotate together on the connecting rod 5 inside the fixed frame 4. Both reinforcement plates 2 are rotated and adjusted towards the center. At this time, the mating surface 3 of the reinforcement plate 2 will be parallel to the fixed plate 8. Then, the personnel rotate the rotating block 7 to make the fixing screw 6 rotate and descend inside the fixed frame 4, thereby driving the fixed plate 8 to descend to the point where it abuts against the mating surface 3 of the reinforcement plate 2.
