Description

Technical Field

[0001] This utility model relates to the field of slope reinforcement technology, and in particular to a slope reinforcement device for open-pit coal mines. Background Technology

[0002] In open-pit coal mining, slope stability is one of the key factors ensuring the safety and efficient operation of the mine. Due to the influence of natural conditions and mining activities, slopes face challenges from various unstable factors, among which water plays a particularly significant role. The scouring and erosion of slopes by rainwater, groundwater, and surface runoff can not only lead to slope instability but also trigger geological disasters such as landslides, causing severe economic losses and environmental damage.

[0003] Traditional slope reinforcement methods mainly include physical reinforcement measures such as anchor bolts, retaining walls, and shotcrete slope protection. While these methods can improve slope stability to some extent, they do not provide effective solutions for water-related slope problems, such as soil erosion, soil softening, and slope surface erosion. Furthermore, when heavy rainfall or rapid snowmelt cannot effectively drain the water, it accumulates on the slope surface or seeps into the soil, increasing soil saturation, reducing its shear strength, and thus exacerbating the risk of slope instability.

[0004] To address the aforementioned issues, we propose an open-pit coal mine slope reinforcement device. This device can divert and drain water that cannot seep into the soil, reducing the direct impact of water on the slope, enhancing slope stability, reducing the risk of soil erosion and slope damage, and ensuring the safe operation of the mine. Summary of the Invention

[0005] To overcome the shortcomings of traditional slope reinforcement methods, which mainly include physical reinforcement measures such as anchor bolts, retaining walls, and shotcrete slope protection, although these methods can improve slope stability to a certain extent, they cannot solve problems such as soil erosion, soil softening, and slope surface erosion. This utility model provides an open-pit coal mine slope reinforcement device. This slope reinforcement device can divert and drain water that cannot seep into the soil, reduce the direct impact of water on the slope, enhance slope stability, reduce the risk of soil erosion and slope damage, and ensure the safe operation of the mine.

[0006] An open-pit coal mine slope reinforcement device includes a fixing plate, with ground nails fixedly connected to the four corners of the bottom end of the fixing plate. An installation plate is embedded and fixedly connected to the fixing plate. The installation plate is connected to equidistantly distributed water collection frames. A covering net is fixedly connected between the bottom ends of the equidistantly distributed water collection frames. Equidistantly distributed connecting pipes are connected between adjacent water collection frames. An equidistantly distributed drainage pipe is connected to the front side of the outermost water collection frame. The tail end of the drainage pipe extends out of the top of the fixing plate. The fixing plate is provided with a drainage component for draining excess water. The fixing plate is also provided with a splicing component for splicing adjacent fixing plates together.

[0007] To further explain, the bottom end of the ground nail is cone-shaped and is used to insert into the soil to reinforce the fixing plate.

[0008] To further explain, the drainage assembly includes a baffle plate, which is fixedly connected to the side of the fixed plate away from the drain pipe. Two horizontally symmetrical guide frames are fixedly connected to the top of the fixed plate, and a guide block is fixedly connected to the baffle plate.

[0009] To further explain, both sides of the baffle plate have guide holes that communicate with the guide frame.

[0010] To further explain, the splicing assembly includes a first splicing plate, which is fixedly connected to one side of the fixed plate, and a second splicing plate is fixedly connected to the other side of the fixed plate.

[0011] To further explain, the second splicing plate and the first splicing plate have a mutually compatible concave-convex structure.

[0012] Compared with the prior art, this utility model has the following advantages: the ground nails are inserted into the soil to fix the fixing plate to the slope to strengthen the slope; the first splicing plate and the second splicing plate can be used to splice two adjacent fixing plates together, improving the stability of the installation of a single fixing plate; the covering net covers the soil surface to prevent the soil from loosening and sliding down; when it rains, rainwater seeps into the soil through the water collection frame and the covering net; when the soil cannot absorb rainwater, the excess rainwater is collected in the water collection frame, and the excess water is transported forward through the connecting pipe, and finally discharged to the upper part of the fixing plate through the drainage pipe, and then discharged downward from the surface of the fixing plate, avoiding a large amount of rainwater flowing from the lower side of the fixing plate to wash away the soil and cause soil loss, reducing the direct impact of water on the slope, enhancing the stability of the slope, reducing the risk of soil erosion and slope damage, and ensuring the safe operation of the mine.

Detailed Implementation

[0020] 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.

[0021] Example 1: A slope reinforcement device for open-pit coal mines, such as Figures 1-6 As shown, the system includes a fixing plate 1, ground nails 2, mounting plate 3, water collection frames 4, covering net 5, connecting pipes 6, drainage pipes 7, drainage components, and splicing components. Ground nails 2 are fixedly connected to the four corners of the lower side of the fixing plate 1. The lower end of the ground nails 2 is conical and used to insert into the soil to reinforce the fixing plate 1. The mounting plate 3 is embedded and fixedly connected to the middle of the fixing plate 1. Water collection frames 4 are connected to the mounting plate 3 at equal intervals. Covering net 5 is fixedly connected between the lower sides of the water collection frames 4 at equal intervals. Three connecting pipes 6 at equal intervals are connected between two adjacent water collection frames 4. Three drainage pipes 7 at equal intervals are connected to the front side of the frontmost water collection frame 4. The tail end of the drainage pipe 7 extends out of the upper side of the fixing plate 1. The fixing plate 1 is equipped with a drainage component for draining excess water. The fixing plate 1 is equipped with a splicing component for splicing two adjacent fixing plates 1 together.

[0022] When using this device, workers move it to the designated location and insert the ground nails 2 into the soil to fix the fixing plate 1 to the slope, thus reinforcing the slope. The splicing components can splice two adjacent fixing plates 1 together, turning the device from a small unit into a large whole, thereby improving the stability of the installation. After the device is installed, the covering net 5 covers the soil surface to prevent the soil from loosening and sliding down. When it rains, rainwater seeps into the soil through the water collection frame 4 and the covering net 5. When the soil cannot absorb the rainwater, the excess rainwater is collected in the water collection frame 4 and discharged through the connecting pipe 6 to... The water is conveyed from the front and finally discharged to the upper side of the fixed plate 1 through the drainage pipe 7, and then discharged downward from the surface of the fixed plate 1. This avoids a large amount of rainwater flowing from the lower side of the fixed plate 1, which would cause soil erosion. Furthermore, since this device is installed in multiple spliced ​​configurations, the rainwater discharged downward from the surface of the rear fixed plate 1 will flow onto the front fixed plate 1, and then be collected and guided by the drainage components. The surface rainwater will then enter the water collection frame 4 again. In this way, while reinforcing the slope, water that cannot seep into the soil can be diverted and discharged separately, reducing the direct impact of water on the slope, enhancing the stability of the slope, reducing the risk of soil erosion and slope damage, and ensuring the safe operation of the mine.

[0023] Example 2: Based on Example 1, such as Figure 1 , Figure 4 and Figure 5 As shown, the drainage assembly includes a baffle plate 8, a guide frame 9, and a guide block 10. The baffle plate 8 is fixedly connected to the upper rear part of the fixed plate 1. The guide frame 9 is fixedly connected to the upper left and right parts of the fixed plate 1. The baffle plate 8 has guide holes on the left and right parts that communicate with the guide frame 9. The guide block 10 is fixedly connected to the baffle plate 8.

[0024] When using the device, rainwater discharged downwards from the surface of the rear fixed plate 1 will flow forward and enter the baffle plate 8. It will then be guided to both sides through the guide block 10. The rainwater will enter the guide frame 9 through the guide hole and then be guided forward through the guide frame 9 to prevent rainwater from entering the water collection frame 4 again and washing the soil.

[0025] like Figure 1 and Figure 6 As shown, the splicing assembly includes a first splicing plate 11 and a second splicing plate 12. The first splicing plate 11 is fixedly connected to the front side of the fixing plate 1, and the second splicing plate 12 is fixedly connected to the rear side of the fixing plate 1. The second splicing plate 12 and the first splicing plate 11 have a mutually compatible concave-convex structure.

[0026] When using the device, the operator controls the first splicing plate 11 on the rear fixed plate 1 to splice with the second splicing plate 12 on the front fixed plate 1, so that the upper fixed plate 1 rests on the lower fixed plate 1, ensuring that the rainwater discharged from the upper fixed plate 1 flows away from the surface of the lower fixed plate 1. Furthermore, splicing adjacent fixed plates 1 can also improve the stability of the installation of a single fixed plate 1.
