Description

Technical Field

[0001] The utility model relates to the technical field of tailings pit reclamation, in particular to a device for improving the bearing capacity of a tailings pit reclamation. Background Art

[0002] With the development of the mining industry, some open-pit mines have been converted into tailings pits after passing safety assessments, environmental impact assessments and other reviews. However, since the tailings mud of such tailings ponds has a high water content and low bearing capacity, it is difficult for personnel and equipment to work on them. The general push-and-drain construction process consumes a lot of backfill material and there are safety and environmental risks such as collapse and silt heave.

[0003] The moisture content of tailings in open-pit tailings pits is around 70%. The current backfill process consumes a lot of backfill material, which is a huge expense for the project. At the same time, since the water in the reservoir is difficult to drain, the lightweight tailings are prone to bulging. Since the particles are around 500 mesh and contain water, it is difficult for personnel and equipment to level them. Currently, galvanized mesh and bamboo rafts are laid on the tailings pit, but the bamboo rafts are placed randomly on the galvanized mesh and will be pushed aside when crushed by mechanical equipment, requiring staff to place them back and forth.

[0004] Therefore, we have made improvements to this problem and proposed a device for improving the bearing capacity of tailings pit reclamation. Utility Model Content

[0005] The purpose of the utility model is to solve the existing problem of laying galvanized mesh and bamboo raft on the tailings pit, but the bamboo raft is placed randomly on the galvanized mesh, and will be pushed aside when being crushed by mechanical equipment, and workers are required to place it back and forth.

[0034] Example 1

[0035] Please refer to Figure 1-6A device for improving the bearing capacity of a tailings pit reclamation comprises: a galvanized mesh body 1, with multiple bamboo raft bodies 2 mounted above the galvanized mesh body 1, a connecting block 3 disposed between the galvanized mesh body 1 and the bamboo raft bodies 2, a fixing assembly 5 disposed on the lower side of the connecting block 3, an installation assembly 4 disposed within the connecting block 3, and mounting slots 6 disposed at the four corners of the bamboo raft bodies 2. The fixing assembly 5 includes fixing hooks 501 disposed on either side of the bottom of the connecting block 3, which engage with the galvanized mesh body 1. T-shaped blocks 502 are mounted above the fixing hooks 501, and T-shaped slots 503 are disposed on either side of the bottom of the connecting block 3, which slide into the T-shaped blocks 502. A fixing column 504 is mounted on the bottom of the connecting block 3, and a connecting bracket 505 is rotatably engaged with the fixing column 504. The connecting bracket 505 is located above the T-shaped blocks 502 within the connecting block 3. Grooves 506 are formed on both sides of the connecting frame 505, and connecting posts 507 are mounted on the upper side of the T-shaped block 502, which flexibly fit within the grooves 506. A threaded rod 508, which extends through the outer side of the connecting block 3 side plate, rotatably fits within one of the T-shaped slots 503. A first threaded groove 509 is formed on one side of one of the T-shaped blocks 502, which threadably engages with the threaded rod 508.

[0036] Implementation process: By rotating the threaded rod 508, one of the T-shaped blocks 502 is driven to slide in the T-shaped groove 503. The sliding T-shaped block 502 drives the other T-shaped block 502 to slide in the opposite direction through the cooperation of the connecting frame 505 and the connecting column 507, so that the two fixing hooks 501 move in opposite directions to fix the connecting block 3 on the galvanized mesh body 1, thereby reducing the situation where the bamboo raft body 2 is placed arbitrarily on the galvanized mesh body 1 and needs to be moved back and forth; the galvanized mesh body 1 can increase the durability of use and reduce the risk of backfill collapse. The bamboo raft body 2 can generate some buoyancy by increasing the surface area, allowing people to enter the silt area. The device is laid in the field. At the same time, due to the pushing and rafting operation process, adding bamboo rafts can increase the strength of the device to prevent the device from being damaged by mechanical power or some large stones during the pushing and rafting operation; the galvanized mesh body 1 can be a galvanized chain link wire mesh with a width of 2m, a mesh size of 5-6cm, and a wire diameter of 3-4mm. The bamboo raft body 2 can be a 100cm*200cm bamboo fixed by iron wire. The device is laid horizontally on the tailings, and 50cm of soil and stone are backfilled by dump trucks and bulldozers. Then a layer of the device is laid to cover 50-100cm of soil and stone. According to the different water content of the tailings, the number of laying layers of the device is increased. When the platform is relatively stable, the soil and stone can be directly backfilled.

[0037] Implementation benefits: the bamboo raft body 2 can be fixedly installed on the galvanized mesh body 1 through the connecting block 3.

[0038] Example 2

[0039] Mounting assembly 4 includes a second threaded groove 401 formed on the upper side of connecting block 3. A threaded post 402 is threadedly engaged with the inner thread of second threaded groove 401. A mounting plate 403, which is mounted at the lower end of threaded post 402 and located within mounting groove 6, is mounted. A drill bit 404 is mounted on the underside of mounting plate 403. T-shaped mounting groove blocks 8 and T-shaped mounting blocks 7 are mounted on the two side panels of connecting block 3, respectively. The T-shaped mounting block 7 between two adjacent connecting blocks 3 mates with the T-shaped mounting groove block 8.

[0040] Implementation process: The four corners of the bamboo raft body 2 are placed in the mounting groove 6 of the connecting block 3, and then the threaded column 402 is rotated downward to allow the drill bit 404 to penetrate the bamboo raft body 2. The mounting plate 403 squeezes and fixes the bamboo raft body 2, thereby ensuring that the connecting block 3 is fixedly installed at the four corners of the bamboo raft body 2. The T-shaped mounting block 7 between two adjacent connecting blocks 3 cooperates with the T-shaped mounting groove block 8 to ensure that the adjacent bamboo raft bodies 2 are connected through the connecting block 3 to form a whole.

[0041] Implementation benefits: The connection blocks 3 can be fixedly installed at the four corners of the bamboo raft body 2.

[0042] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
