Abstract
Description
Technical Field
[0001] This application relates to the field of slope protection technology, and in particular to slope protection structures for open-pit mine spoil heaps. Background Technology
[0002] Open-pit mine slope treatment engineering is guided by theories from mining science, soil and water conservation, rock mechanics, soil mechanics, and other disciplines, and different slope treatment methods are used for slopes of different rock types and different degrees of importance.
[0003] Currently existing ecological protection structures for slope reinforcement at open-pit mine spoil heaps consist of only a single layer of protective netting covering the slope surface. This netting is lightweight and easily blown away by the wind, rendering it ineffective and unable to provide long-term, long-term coverage of the slope. Furthermore, this type of netting does not have a drainage function, allowing rainwater to continue eroding the soil at the bottom during severe weather, resulting in soil erosion. It also fails to collect natural rainfall, leading to reduced erosion of the spoil heap and consequently, a decrease in the amount of mineral soil. Utility Model Content
[0004] To address or partially address the problems existing in related technologies, this application provides a slope protection structure for open-pit mine spoil heaps, which can effectively protect the slope and collect and treat rainwater.

[0006] A base, on one side of which a support frame is fixedly connected;
[0007] The inner wall of the support frame is fixedly connected to a protective layer, and the other end of the support frame is fixedly connected to a connecting plate.
[0008] The top of the support frame is fixedly connected to a fixing strip, and the top of the fixing strip is fixedly connected to a plug-in tube. The plug-in tube is internally threaded with a ground nail, which penetrates and connects to the support frame.
[0009] The protective layer includes a cover plate with multiple water tanks on its top and four mounting holes on its top.
[0010] The base has grooves on both sides inside, and a filter device is connected through the inside of the grooves.
[0011] The filter device includes a connecting cylinder, and a discharge device is fixedly connected to the bottom of the filter device.
[0012] The discharge device includes sewage pipes.
[0013] Optionally, in some embodiments of this application:

[0016] A filter box is inserted into the top of the connecting cylinder, and a mesh is embedded in the upper part of the outer wall of the filter box.
[0017] Optionally, in some embodiments of this application:
[0018] The bottom of the connecting box is fixedly connected to the top of the sewage pipe, and the bottom of the filter box penetrates the inside of the groove so that the strainer is installed above the groove.
[0019] Optionally, in some embodiments of this application:
[0020] One end of the sewage pipe is connected to a pump, and the other end of the pump is fitted with a drain pipe.

This netting is lightweight and easily blown away by the wind, rendering it ineffective and unable to provide long-term, long-term coverage of the slope. Furthermore, this type of netting does not have a drainage function, allowing rainwater to continue eroding the soil at the bottom during severe weather, resulting in soil erosion.

[0036] To address the aforementioned issues, this application provides a slope protection structure for an open-pit mine spoil heap, which effectively protects the slope and collects and treats rainwater.
[0037] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0038] Figure 1 This is a schematic diagram of an ecological protection structure for slope reinforcement of an open-pit mine spoil heap in an embodiment of this application.
[0039] Figure 2 This is a structural schematic diagram of the support frame 2 in an embodiment of this application;
[0040] Figure 3 This is a schematic diagram of the structure of the base 1 in an embodiment of this application;
[0041] Figure 4 This is a schematic diagram of the structure of the filter device 4 in the embodiments of this application.
[0042] See Figure 1-4 A slope protection structure for an open-pit mine spoil heap, comprising:
[0043] The base 1 has a support frame 2 fixedly connected to one side. The support frame 2 is made of plastic and can be easily adjusted according to the accumulation height of the slope.
[0044] The inner wall of the support frame 2 is fixedly connected to a protective layer 3, and the other end of the support frame 2 is fixedly connected to a connecting plate 6.
[0045] The top of the support frame 2 is fixedly connected to a fixing strip 21, and the top of the fixing strip 21 is fixedly connected to a plug tube 22. The plug tube 22 is internally threaded with a ground nail 23, which penetrates and connects to the support frame 2.
[0046] In this embodiment, the slope protection structure is made more convenient to use through the combined action of the support frame 2 and the protective layer 3. The cross-section of the fixing strip 21 is U-shaped, and the top is connected to the plug-in tube 22, which makes the connection of the ground nail 23 inside more stable, ensuring the fixed installation of the support frame 2. It will not leave the slope surface in windy weather, effectively protecting the slope.
[0047] The protective layer 3 includes a cover plate 31, the top of which has multiple water tanks 32 and four mounting holes 33. The cover plate 31 is made of plastic.
[0048] In this embodiment, by opening multiple sets of water troughs 32 on the top of the cover plate 31, it is convenient to collect and discharge rainwater after the protective layer 3 is installed on the slope surface, forming an artificial drainage channel, which is more convenient to use and avoids the slope being washed away by rainwater, resulting in a reduction of mineral soil.
[0049] The base 1 has grooves 11 on both sides inside, and a filter device 4 is connected through the inside of the grooves 11.
[0050] The filter device 4 includes a connecting cylinder 41, and a discharge device 5 is fixedly connected to the bottom of the filter device 4.
[0051] Specifically: the top of the connecting cylinder 41 is fixedly connected to the bottom of the base 1, the connecting cylinder 41 is installed at the bottom of the groove 11, the bottom of the connecting cylinder 41 is fixedly connected to the connecting component 42, the bottom of the connecting component 42 is inserted into the connecting box 45, and the inside of the connecting box 45 is fixedly connected to the filter screen 46.
[0052] Specifically: a filter box 43 is inserted into the top of the connecting cylinder 41, and a mesh 44 is embedded in the upper part of the outer wall of the filter box 43.
[0053] Specifically: the bottom of the connecting box 45 is fixedly connected to the top of the sewage pipe 51, and the bottom of the filter box 43 penetrates the interior of the groove 11 so that the strainer 44 is installed above the groove 11.
[0054] In this embodiment, by setting up a base 1, rainwater collected by the protective layer 3 can be discharged into the base 1. By setting up a filter box 43, some suspended particles can be intercepted to avoid clogging. At the same time, by setting up a filter screen 46 inside the connecting box 45, a second layer of filtration can be achieved. The filtered rainwater enters the sewage pipe 51 for collection and is then discharged into the water channel by the pump 52. This allows for the collection and treatment of water and soil flow, and is more convenient to use.
[0055] The discharge device 5 includes a sewage pipe 51.
[0056] Specifically: one end of the sewage pipe 51 is connected to a pump 52, and one end of the pump 52 is fitted with a drain pipe 53.
[0057] The technical solutions provided in this application have the following beneficial effects:
[0058] This application makes the slope protection structure more convenient to use through the combined action of the support frame 2 and the protective layer 3. The cross-section of the fixing strip 21 is U-shaped, and the top is connected to the plug-in tube 22, which makes the connection of the internal ground nails 23 more stable, ensuring the fixed installation of the support frame 2. It will not leave the slope surface in windy weather, effectively protecting the slope.
[0059] This application utilizes multiple water channels 32 on the top of the cover plate 31 to facilitate the collection and discharge of rainwater after the protective layer 3 is installed on the slope surface, forming an artificial drainage channel. This makes the application more convenient and prevents the slope from being eroded by rainwater, thus reducing the amount of mineral soil. Simultaneously, by setting up the base 1, rainwater collected by the protective layer 3 can be discharged into the base 1, and the filtered rainwater enters the sewage pipe 51 for collection before being discharged into the drainage channel by the pump 52. This allows for the collection and treatment of rainwater runoff and makes the application more convenient.
