Description

Technical Field

[0001] The utility model relates to the technical field of slope reinforcement, in particular to an open-pit coal mine slope reinforcement structure. Background Art

[0002] Open-pit coal mine slope reinforcement refers to various engineering measures used to strengthen and protect slopes during the mining process to ensure their stability and safety. Slope reinforcement is typically achieved by laying cement blankets, a flexible protective material primarily made of cement, typically a mixture of cement and polymers. Cement blankets are adaptable to various slopes and terrains, effectively covering irregular slope surfaces and ensuring effective reinforcement.

[0003] Lay the cement blanket on the slope surface, and then spray water on the cement blanket. After spraying water, a hydration reaction will occur, thereby enhancing its compressive and tensile strength, improving the stability of the slope, and preventing geological disasters such as slope landslides and collapses, ensuring the safety of miners and the normal operation of equipment.

[0004] When laying cement blankets using existing technology, the cement blankets are fixed to the slopes using U-shaped nails. However, the U-shaped nails cannot effectively penetrate the soil layer or be fixed on a solid foundation, and the cement blankets cannot be stably fixed. When the slope is steep and the length of the laid cement blanket is too long, gravity causes the cement blanket to shift and slide easily, which will cause the slope surface to lose its reinforcement effect and increase the risk of landslide or collapse.

The fixing mechanism 3 includes an inserting rod 31, a slider 32, a connecting rod 1 33, a connecting rod 2 34 and a linkage rod 35. The inserting rod 31 is inserted into the sleeve 2. A plurality of side grooves 311 are provided on the side of the inserting rod 31. The plurality of side grooves 311 are linearly arranged along the length direction of the inserting rod 31. Grouting holes 313 are provided on the end surface of the inserting rod 31. The grouting holes 313 are connected to the side grooves 311. The slider 32 is slidably connected to the side grooves 311. Both ends of the slider 32 are rotatably connected to the connecting rod 1 33. The connecting rod 2 34 is rotatably connected to the free end of the connecting rod 1 33. The free end of the connecting rod 2 34 is rotatably connected to the inserting rod 31. The free end of the connecting rod 2 34 is provided between the two side grooves 311. A support plate 36 is provided at the connection position of the connecting rod 1 33 and the connecting rod 2 34. The cement blanket 1 is laid on the slope to be reinforced. Multiple rows of cement blankets 1 are arranged side by side to cover the entire slope. Holes opened on the cement blanket 1 are drilled. The sleeve 2 is inserted into the hole of the cement blanket 1. The fixing mechanism 3 is inserted into the sleeve 2. The fixing mechanism 3 expands outward and engages with the inside of the hole in the slope. Concrete is poured into the grouting hole 313 on the end face of the insertion rod 31. The concrete flows into the hole in the slope through the side groove 311. After the concrete solidifies, it fixes the fixing mechanism 3 on the slope to reinforce it.

[0028] like Figure 5As shown, a connecting head 321 is provided on the slider 32, and a plurality of limit heads 351 are fixedly connected to the linkage rod 35. The plurality of limit heads 351 are linearly arranged along the length direction of the linkage rod 35. The connecting head 321 is located between the two limit heads 351. A sliding head 312 is fixedly connected to the end of the insertion rod 31. The linkage rod 35 is slidably connected in the sliding head 312. Two fixing nuts 352 are provided at the end of the linkage rod 35. The two fixing nuts 352 are respectively located on both sides of the sliding head 312. The sliders 32 are connected through the linkage rod 35. Pushing the linkage rod 35 can simultaneously push multiple connecting heads 321 to drive the slider 32 to slide along the side groove 311. As the slider 32 moves, the linkage mechanism composed of multiple connecting rods 1 33 and connecting rods 2 34 moves at the same time. The distance between the connection between the connecting rod 1 33 and the connecting rod 2 34 on both sides of the insertion rod 31 and the insertion rod 31 increases, and the fixing mechanism 3 expands outward. The support plates 36 on both sides are tightly attached to the inner wall of the slope hole, so that the fixing mechanism 3 can be fixed on the slope. Tighten the fixing nut 352 on the linkage rod 35 so that the two fixing nuts 352 are clamped on both sides of the sliding head 312, so that the fixing mechanism 3 remains in an expanded state.

The diameter of the connecting ring 21 around the sleeve 2 is larger than the size of the hole in the cement blanket 1, which enables the sleeve 2 to be fixed in the hole. The connecting ring 21 is provided on the outside of the upper surface of the cement blanket 1. After grouting is completed, the fixing plug 4 is inserted into the opening of the grouting hole 313 and fixed to the end face of the connecting ring 21, thereby fixing the fixing mechanism 3 to the sleeve 2. The fixing mechanism 3 can firmly fix the cement blanket 1 to the slope and prevent the cement blanket 1 from slipping.

[0030] like Figure 6 As shown, a side strip 5 is provided at the joint of the two cement blankets 1. A sealing strip 51 is provided on one side of the side strip 5. The sealing strip 51 is installed on the cement blanket 1 to improve the waterproof capability of the side strip 5. A U-shaped staple 52 is fixed to the other side of the side strip 5. To prevent water from seeping into the slope through the joint of the cement blanket 1 and causing erosion, the side strip 5 is nailed to the joint of the cement blanket 1 with a U-shaped staple 52 to seal the side strip 5. This also serves to further secure the cement blanket 1.

[0031] Adopting this utility model, such as Figure 1 and Figure 2As shown, the cement blanket 1 is laid on the slope to be reinforced, and multiple rows of cement blankets 1 are arranged side by side to cover the entire slope. Holes are punched in the holes opened on the cement blanket 1, and the sleeves 2 are inserted into the holes of the cement blanket 1. The fixing mechanism 3 is inserted into the interior of the sleeve 2, and the linkage rod 35 is pushed to simultaneously push multiple connecting heads 321 to drive the slider 32 to slide along the side groove 311. As the slider 32 moves, the linkage mechanism composed of multiple connecting rods 1 33 and connecting rods 2 34 moves at the same time, and the distance between the connection point of the connecting rod 1 33 and the connecting rod 2 34 on both sides of the insertion rod 31 and the insertion rod 31 increases, the fixing mechanism 3 expands outward, and the support plates 36 on both sides are tightly attached to the inner wall of the holes punched in the slope, so that the fixing mechanism 3 can be fixed on the slope, and the fixing nuts 352 on the linkage rod 35 are tightened so that the two fixing The nuts 352 are clamped on both sides of the sliding head 312, so that the fixing mechanism 3 remains in an expanded state, and concrete is poured into the grouting hole 313 on the end face of the insertion rod 31. The concrete flows into the slope drilling through the side groove 311. After the concrete solidifies, it reinforces the fixing mechanism 3 on the slope. After grouting is completed, the fixing plug-in 4 is inserted into the orifice of the grouting hole 313, and the fixing plug-in 4 is fixed to the end face of the connecting ring 21, so that the fixing mechanism 3 and the sleeve 2 are fixed together. The fixing mechanism 3 can firmly fix the cement blanket 1 to the slope to prevent the cement blanket 1 from slipping. In order to prevent water from seeping into the slope from the joints of the cement blanket 1 and causing erosion of the slope, U-shaped nails 52 are used to nail the edge strips 5 to the joints of the cement blanket 1 for sealing, which also plays a further role in fixing the cement blanket 1.
