Description

Technical Field

[0001] The invention relates to the technical field of coal mine soil slope reinforcement, and in particular to an open-pit coal mine soil slope reinforcement device. Background Art

[0002] The purpose of soil slope reinforcement in open-pit coal mines is to prevent landslides caused by coal mining. However, traditional reinforcement methods often use cement-reinforced steel mixtures. Although this design method has obvious reinforcement effects, it is expensive and cannot be reused multiple times.

[0003] Therefore, in order to solve this problem, we propose an open-pit coal mine soil slope reinforcement device that can be used repeatedly to reduce costs. Summary of the Invention

[0004] In view of the defects in the prior art, the present invention provides an open-pit coal mine soil slope reinforcement device, which can be used repeatedly to reduce costs.

[0005] The present invention provides an open-pit coal mine soil slope reinforcement device, comprising: a reinforcement network and a reinforcement component; the reinforcement network includes a reinforcement network; the reinforcement component includes a reinforcement excavation pile column, wherein under the construction of external equipment, a plurality of pile holes are provided above and below the coal mine soil slope; the reinforcement network is installed at the coal mine soil slope and covers the coal mine soil slope; the reinforcement excavation pile column is provided in plurality, and is respectively installed one by one at the pile holes above and below the coal mine soil slope, and extends upward; wherein the reinforcement network is detachably connected to the reinforcement excavation pile columns.

[0006] Furthermore, the reinforcement net is made of steel cables. In actual use, the reinforcement net woven with steel cables has high material strength and long service life, can effectively meet the requirements of repeated use, and has a certain degree of flexibility, so that the tensile strength is high and it can be effectively applied to sudden slope collapse.

[0007] Furthermore, the reinforced excavation pile column includes a main column sleeve and an impact column. The main column sleeve is provided with a sliding cavity, one end of which is open; one end of the impact column is slidably mounted in the sliding cavity of the main column sleeve. In actual use, the purpose of this design is to deepen the excavation depth of the reinforced excavation pile in the pile hole. In actual operation, the reinforced excavation pile column is first placed as a whole into the pre-set pile hole, and then the impact column is hoisted by the hoisting equipment. After that, the impact column is placed and impacts the main column sleeve. In this way, the depth of the main column sleeve in the pile hole can be extended downward, further achieving the reinforcement effect.

[0008] Furthermore, the main column sleeve is provided with lifting holes. The lifting holes are provided in multiple locations and are evenly distributed along the end of the sliding cavity. The reinforced excavation pile column is lifted and transported with external equipment through the lifting holes. In actual use, the lifting holes are threaded holes. This design is designed to facilitate connection with lifting equipment, such as heavy-duty hooks. Components such as heavy-duty hooks are installed one by one in the lifting holes, and then connected to an external crane through the heavy-duty hooks, so that the reinforced excavation pile column can be lifted and transported as a whole. At the same time, the reinforcement net is also detachably connected to the reinforced excavation pile column through the lifting holes.

[0009] Furthermore, the main column sleeve is also provided with side holes, and the side holes are provided in multiple locations and are arranged in a direction away from the hanging hole. The impact column is provided with a liquid flow cavity, wherein the liquid flow cavity is communicated with the side holes.

[0010] Furthermore, the impact column is also provided with a discharge hole, which is arranged on the side of the impact column and communicates with the fluid chamber. In actual use, the purpose of this design is to allow the reinforcement fluid to flow from the discharge hole, through the fluid chamber, and through the side hole to the inner wall of the pile hole. In this way, the reinforcement between the reinforced pile column and the pile hole can be achieved. The reinforcement fluid is made of a mixed material mainly composed of polyurethane foam; in this way, effective reinforcement can be achieved, and the decomposition of the mixed material mainly composed of polyurethane foam can be utilized. When the reinforced pile column needs to be disassembled, the main column sleeve is energized. Since the main column sleeve is made of metal material, the principle of metal heating is utilized to achieve thermal liquefaction of the reinforcement fluid, and then it is removed through external equipment, making the device detachable and reusable.

[0011] Furthermore, the reinforcement assembly further includes a lifting ring, which is installed at the other end of the impact column; the impact column is lifted by the lifting ring. In actual use, this design is for the convenience of lifting.

[0012] Furthermore, it also includes a plurality of rotating abutting members, each of which is installed on the reinforcement net and abuts against the surface of the soil slope of the open-pit coal mine. In actual use, the purpose of this design is to achieve the reinforcement of the reinforcement net and the surface of the soil slope of the open-pit coal mine, and effectively ensure the reinforcement effect of the soil slope of the open-pit coal mine through multiple clamping and abutting methods.

[0013] Furthermore, the rotating clamping member includes a mounting shaft, a motor, and a rotating claw. The motor is in transmission connection with the rotating claw and drives the rotating claw to rotate. In actual use, this design is designed to achieve an automatic reinforcement effect. The motor drives the rotating claw to reinforce the surface of the soil slope of the open-pit coal mine. In this way, when reinforcement is no longer needed, the rotating claw can be disengaged by rotating it, which facilitates the subsequent removal of the reinforcement mesh.

[0014] From the above technical solution, it can be seen that the beneficial effects of the open-pit coal mine soil slope reinforcement device provided by the present invention are:

[0015] (1) In actual application, the combination of reinforcement network and reinforcement components effectively replaces the traditional cement steel reinforcement method, reduces costs, and can also achieve repeated multiple uses, greatly improving the overall application efficiency.

[0016] (2) Furthermore, by presetting a plurality of pile holes, the construction method becomes common and easy to implement, thus avoiding the phenomenon of cost increase caused by new construction technology. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0025] The embodiment is basically as shown in the attached Figures 1 to 4 As shown:

[0026] like Figure 1 - Figure 4 As shown, the present embodiment provides an open-pit coal mine soil slope reinforcement device, which can be used repeatedly to reduce costs.

[0027] The present invention provides a device for reinforcing an open-pit coal mine soil slope, comprising: a reinforcement network 1 and a reinforcement assembly 2; the reinforcement network 1 includes a reinforcement mesh 11; the reinforcement assembly 2 includes reinforcement piles 21, wherein a plurality of pile holes 100 are provided above and below the coal mine soil slope under external equipment construction; the reinforcement mesh 11 is installed at the coal mine soil slope and covers the coal mine soil slope; a plurality of reinforcement piles 21 are provided, and are installed one by one in the pile holes 100 above and below the coal mine soil slope and extend upward; the reinforcement mesh 11 is detachably connected to the reinforcement piles 21. In actual use, the combined use of the reinforcement network 1 and the reinforcement assembly 2 effectively replaces traditional cement and steel reinforcement methods, reducing costs while also enabling repeated use, greatly improving overall efficiency. Furthermore, by presetting a plurality of pile holes 100, the construction method becomes common and easy to implement, thus avoiding the phenomenon of cost increase caused by a new construction process.

[0028] In this embodiment, the reinforcement mesh 11 is made of steel cables. In actual use, the reinforcement mesh 11 woven with steel cables has high material strength and long service life, which can effectively meet the requirements of repeated use. It also has a certain degree of flexibility, resulting in high tensile strength and can be effectively applied to sudden slope collapse.

[0029] In this embodiment, the reinforced excavation pile column 21 includes a main column sleeve 211 and an impact column 212. The main column sleeve 211 is provided with a sliding cavity 2111, one end of which is open. One end of the impact column 212 is slidably mounted within the sliding cavity 2111 of the main column sleeve 211. In actual use, the purpose of this design is to deepen the excavation depth of the reinforced excavation pile within the pile hole 100. In actual operation, the reinforced excavation pile column 21 is first placed in its entirety into the pre-set pile hole 100. Then, the impact column 212 is hoisted using a hoisting device, and then the impact column 212 is placed so that it impacts the main column sleeve 211. This allows the main column sleeve 211 to extend downward within the pile hole 100, further achieving a reinforcement effect.

[0030] In this embodiment, the main column sleeve 211 is further provided with lifting holes 2112. Multiple lifting holes 2112 are provided and evenly spaced along the end of the sliding cavity 2111. The reinforced excavation pile column 21 is lifted and transported to and from external equipment via the lifting holes 2112. In actual use, the lifting holes 2112 are threaded holes. This design facilitates connection with a lifting device, such as a heavy lifting hook. Components such as the heavy lifting hooks are mounted one by one on the lifting holes 2112, and then connected to an external crane via the heavy lifting hooks. This allows the reinforced excavation pile column 21 to be hoisted and transported as a whole. Furthermore, the reinforcement net 11 is also detachably connected to the reinforced excavation pile column 21 via the lifting holes 2112.

[0031] In this embodiment, the main column sleeve 211 is also provided with a side hole 2113, and the side holes 2113 are provided in multiple locations and are arranged in a direction away from the hanging hole 2112. The impact column 212 is provided with a liquid flow cavity 2121, wherein the liquid flow cavity 2121 is communicated with the side hole 2113.

[0032] In this embodiment, the impact column 212 is further provided with a discharge hole 2122, which is located on the side of the impact column 212 and communicates with the fluid chamber 2121. In practice, this design allows the reinforcement fluid to flow from the discharge hole 2122, through the fluid chamber 2121, and through the side hole 2113 to the inner wall of the pile hole 100. This effectively reinforces the connection between the reinforced pile column 21 and the pile hole 100. The reinforcing fluid is primarily a mixed material composed of polyurethane foam. This effectively reinforces the pile column 21 and utilizes the thermal decomposition of the polyurethane foam-based mixed material. When the reinforced pile column 21 needs to be disassembled, the main column sleeve 211 is energized. Since the main column sleeve 211 is made of metal, the metal heats up and liquefies the reinforcing fluid. The fluid can then be removed through an external device, making the device removable and reusable.

[0033] In this embodiment, the reinforcement assembly 2 further includes a lifting ring 22, which is installed at the other end of the impact column 212; the impact column 212 is lifted by the lifting ring 22. In actual use, this design is for the convenience of lifting.

[0034] This embodiment also includes a rotating abutment 3, which is provided in multiple locations and is mounted on the reinforcement mesh 11 and abuts against the surface of the open-pit coal mine soil slope. In actual use, the purpose of this design is to achieve the reinforcement of the reinforcement mesh 11 and the surface of the open-pit coal mine soil slope, and effectively ensure the reinforcement effect of the open-pit coal mine soil slope through multiple clamping and abutting methods.

[0035] In this embodiment, the rotating clamping member 3 includes a mounting shaft 31, a motor 32, and a rotating claw 33. The motor 32 is in transmission connection with the rotating claw 33 and drives the rotating claw 33 to rotate. In actual use, this design is to achieve an automatic reinforcement effect. The motor 32 drives the rotating claw 33, which, by rotating the claw 33, reinforces the surface of the soil slope of the open-pit coal mine. In this way, when reinforcement is no longer needed, the rotating claw 33 can be disengaged by rotating it, which facilitates the subsequent removal of the reinforcement net 11.

[0036] To sum up, this open-pit coal mine soil slope reinforcement device is not only reasonably designed, but also simple to operate. It can effectively reinforce the soil slope of the open-pit coal mine. At the same time, the device can also be disassembled and reused, which greatly improves the scope of application of the device and can effectively reduce the actual cost. Therefore, the device is suitable for industry promotion.
