Description

Technical Field

[0001] This utility model relates to the field of environmental management, and in particular to a slope protection structure for mine geological environment management. Background Technology

[0002] Slope stabilization, as a core task in the field of mine geological environment management, aims not only to ensure slope stability but also to restore the ecological environment of the mine, in line with the concept of green mining. Among various solutions, sowing grass seedlings to achieve soil stabilization through root systems is a fundamental way to achieve steady ecological restoration of slopes. Due to its low cost, good results, and high ecological compatibility, it has been widely promoted in practical applications. However, in actual construction, slope stabilization, as a long-term project, faces many objective challenges. In ecological restoration, newly sown grass seedlings are relatively fragile. During heavy rains, the water collected at the top of the slope forms a powerful surface runoff, causing concentrated erosion of the slope surface from top to bottom. Existing technologies often only install drainage ditches at the foot of the slope, failing to address the issues in the middle and upper parts of the slope. While some modular slope protection structures divide large slopes into small planting areas to reduce water erosion, their drainage systems are mostly passive, relying on natural water flow. This results in long water flow paths and concentrated energy, still posing a risk of erosion. Furthermore, if a section becomes blocked, the entire drainage system is prone to failure, directly threatening the safety of grass seeds in the planting area. Currently, many effective slope protection solutions suffer from low on-site construction efficiency and high installation costs due to their complex structures and numerous components, making it difficult to promote and apply them on a large scale in vast mining areas. This restricts the progress and scale of ecological restoration. Therefore, there is an urgent need in this field for a slope protection structure that is effective in resisting erosion, has stable drainage, is easy to install, and effectively combats water flow at the top of the slope, providing a more efficient, stable, and easier-to-install slope protection structure for related fields.

[0003] The core defects of existing technologies are that existing slope protection structures are relatively complex to install and many are permanent works. They are not very effective in resisting slope erosion and in the need of large-scale drainage, and are difficult to protect grass seedlings. Utility Model Content

[0004] The purpose of this utility model is to provide a slope protection structure for mine geological environment management, which aims to solve the problems of complex installation, weak resistance to slope top scouring, and weak active drainage and diversion capacity in the above-mentioned technical problems.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A slope protection structure for mine geological environment management includes:

[0007] The earthen slope has a right-angled trapezoidal cross-section;

[0008] A fixing groove is installed on the top surface of the earth slope. A drainage pipe is fixedly connected to the lower surface of the fixing groove, and a No. 1 connection hole is provided on the upper surface of the fixing groove.

[0009] A diversion channel is installed on the side surface of the earth slope. One end of the diversion channel near the top surface of the earth slope is fixedly connected to the upper surface of the No. 1 connecting hole. A diversion port is provided on the side surface of the diversion channel. A No. 2 connecting hole is provided on the upper surface of the diversion channel. A pressure relief port is provided on the inner surface of the diversion channel.

[0010] A planting trough is installed on the side surface of the soil slope. The side surface of the planting trough is fixedly connected to the upper surface of the second connecting hole. A circular frame is fixedly connected to the upper surface of the planting trough.

[0011] A diversion pipe is installed on the side surface of the drain pipe, and the output end of the diversion pipe is fixedly connected to the pressure relief port connection.

[0012] This utility model also has the following technical features:

[0013] In one embodiment of this utility model, a nursery is fixedly connected to the side surface of the soil slope, and the outer surface of the nursery is fixedly connected to the inner surface of the planting trough.

[0014] In one embodiment of the present invention, a first fixing hole is provided on the upper surface of the fixing groove, and the first fixing hole penetrates the fixing groove.

[0015] In one embodiment of this utility model, a second fixing hole is provided on the upper surface of the drainage channel, and the second fixing hole penetrates the drainage channel.

[0016] In one embodiment of this utility model, the upper surface of the planting trough is provided with a No. 3 fixing hole, which penetrates the planting trough.

[0017] In one embodiment of the present invention, an extension portion is fixedly connected to the side surface of the drainage channel, and an extension hole is provided on the upper surface of the extension portion.

[0018] In one embodiment of this utility model, a main water trough is provided on the bottom surface of the earth slope, and the side surface of the main water trough is fixedly connected to the output end of the diversion channel.

[0019] In one embodiment of the present invention, a drainage hole is provided on the lower surface of the planting trough, and the drainage hole penetrates the lower surface of the planting trough.

[0020] Compared with existing technologies, the beneficial effects of this invention are as follows: This device, through its modular design, collects water in a fixed trough at the top of the slope and actively guides and diverts the water flow to pressure relief outlets at different elevations via diversion pipes. Even if a local diversion channel becomes blocked, the water can still be discharged smoothly through other pressure relief outlets, greatly enhancing the drainage system's anti-clogging capability and failure tolerance. Furthermore, the circular frame structure on the upper surface of the planting trough has excellent arched mechanical properties, efficiently converting the vertical impact of rainwater or runoff into a tangential component force, with the connected diversion channel serving as the optimal tangential force. The transfer path smoothly guides the decomposed water flow away, effectively reducing local stress concentration and preventing structural displacement. This design decomposes the traditional top-down concentrated runoff into multiple dispersed and controllable outlet points, fundamentally dismantling the impact energy of the water flow at the top of the slope. At the same time, the fixing trough, diversion channel and planting trough of this device are all prefabricated components, which are quickly connected through multiple connection holes and fixed to the slope surface by each fixing hole. This modular and standardized design greatly simplifies the on-site installation process, reduces the construction difficulty and reliance on skilled workers, and is conducive to large-scale treatment in vast mining areas.

[0033] Reference Figure 1-4 The mine geological environment management slope protection structure of this utility model embodiment includes:

[0034] The earthen slope 10 has a right-angled trapezoidal cross-section. The main body of the treatment object has its cross-section modified into a right-angled trapezoid to provide a stable slope foundation. The installation parts mainly include the top of the slope and the slope surface. The side surface of the earthen slope 10 is fixedly connected to the nursery 11. The outer surface of the nursery 11 is fixedly connected to the inner surface of the planting trough 40. The nursery 11 is the filling material located inside the planting trough 40. It is a special nutrient substrate made of a mixture of topsoil, grass seeds, fertilizer, water-retaining agent and organic fiber, etc., used for planting grass seeds. It is directly filled and fixed inside the planting trough 40. The bottom surface of the earthen slope 10 is provided with a main water trough 12. The side surface of the main water trough 12 is fixedly connected to the output end of the diversion channel 30. The main water trough 12 is a concrete water collection ditch set at the bottom of the earthen slope 10. It is used to safely collect and finally guide all the water flowing out from the entire slope surface, completing the last link of the water cycle.

[0035] The fixing trough 20 is installed on the top surface of the slope 10. It is a strip-shaped trough structure located at the top of the slope and is prefabricated from high-strength engineering plastic. An installation pit is dug at the top of the slope 10 so that its upper surface is flush with the top surface of the slope. It is installed at the top of the slope close to the slope surface so that any water flowing from the top of the slope to the slope surface will be collected in it. A drainage pipe 22 is fixedly connected to the lower surface of the fixing trough 20. The drainage pipe 22 is pre-buried in the slope 10 on the lower surface of the fixing trough 20 and is used to drain the water collected by the fixing trough 20. A first fixing hole 21 is provided on the upper surface of the fixing trough 20. The first fixing hole 21 penetrates the fixing trough 20 and is anchored to the top surface of the slope 10 by anchor rods and other components passing through the first fixing hole 21, so that the position of the fixing trough 20 is effectively fixed. A first connecting hole 23 is provided on the upper surface of the fixing trough 20. The first connecting hole 23 is connected to the top of the uppermost diversion channel 30. The fixing trough 20 and the diversion channel 30 are locked together by the first connecting hole 23 through the connector, which increases the stability of the entire device.

[0036] The diversion channel 30 is installed on the side surface of the earthen slope 10. The diversion channel 30 is a longitudinal main drainage channel laid on the slope surface of the earthen slope 10. It is typically a U-shaped prefabricated trough, buried in a pre-excavated pit on the slope surface. Its outer surface is flush with the slope surface, used to collect water flowing down from the top of the slope and rainwater. One end of the diversion channel 30 near the top surface of the earthen slope 10 is fixedly connected to the upper surface of the first connecting hole 23. The top of the diversion channel 30 is connected to the fixing groove 20 through the first connecting hole 23. The component connecting the diversion channel 30 and the fixing groove 20 is specially made, with a connecting part. Half of the diversion channel 30 does not have this top connecting part. A diversion port 32 is provided on the side surface of the diversion channel 30. The diversion port 32 is a U-shaped hollow groove on both sides, allowing water diverted by the circular frame 41 to enter the diversion channel 30 through the hollow groove. A second fixing hole 31 is provided on the upper surface of the diversion channel 30, and the second fixing hole 31 penetrates through... The drainage channel 30 is anchored to the slope of the earth slope 10 through the anchor rod passing through the second fixing hole 31. The upper surface of the drainage channel 30 is provided with the second connecting hole 33, which is connected to the side of the planting trough 40. The drainage channel 30 is connected to the planting trough 40 by the fixing screw passing through the second connecting hole 33, thereby realizing the splicing of the drainage channel 30 and the planting trough 40. The inner surface of the drainage channel 30 is provided with the pressure relief port 34, which is connected to the output end of the diversion pipe 50, providing an opening for the water discharged from the diversion pipe 50 so that it can reach the diversion pipe 50. The side surface of the drainage channel 30 is fixedly connected with the extension part 36. The upper surface of the extension part is provided with the extension hole 35. The extension part 36 is a plastic structure on the drainage channel 30, which is a plastic plate with a threaded channel. The extension part 36 is spliced ​​with the adjacent drainage channel 30 through the extension hole 35 to extend the drainage path.

[0037] Planting trough 40 is installed on the side surface of the slope 10. Planting trough 40 is the core ecological restoration unit of this device. It is an open frame structure made of corrosion-resistant PVC material, half of which is buried in the soil and half on the slope surface, used to support the nursery 11. The side surface of planting trough 40 is fixedly connected to the upper surface of the second connecting hole 33. The side surface of planting trough 40 has a connecting part for connecting to the second connecting hole 33, including a plastic plate and threaded holes. Planting trough 40 is fixedly connected to the second connecting hole 33 on the drainage channel 30 by fixing screws. The upper surface of planting trough 40 is provided with a third fixing hole 43. 0. An anchor rod is used to pass through the third fixing hole 43 for auxiliary anchoring to fix the position of the planting trough 40. The third fixing hole 43 passes through the planting trough 40. A circular frame 41 is fixedly connected to the upper surface of the planting trough 40. The circular dome structure of the circular frame 41 can effectively disperse and resist the impact force of raindrops and the shear force of water flow by utilizing the circular load-bearing characteristics, and transfer the water flow to the tangential drainage channel 30. A drainage hole 42 is provided on the lower surface of the planting trough 40. The drainage hole 42 can ensure that there is no water accumulation inside, create a good environment for plant roots, and effectively prevent the loss of planting soil. The drainage hole 42 passes through the lower surface of the planting trough 40.

[0038] Diversion pipe 50 is installed on the side surface of drain pipe 22. Diversion pipe 50 is a pipe network connected to the side of drain pipe 22 and must be made of durable PVC material. The output end of diversion pipe 50 is fixedly connected to the connection of pressure relief port 34. The input end of diversion pipe 50 is connected to the connection port on the side surface of drain pipe 22 below fixed groove 20. Multiple output ends are fixedly connected to the pressure relief ports 34 of diversion channels 30 at different height levels. Diversion pipe 50 is inclined downward to connect to pressure relief port 34 to ensure that water flows naturally with gravity and prevent backflow. Through active diversion, the water collected at the top of the slope is actively and accurately transported to the drainage skeleton at different heights of the slope, avoiding the formation of a huge impact after the water accumulates at the top of the slope. Through multi-point drainage, water damage is eliminated from the source. At the same time, its redundant design ensures that even if the drainage of a certain section of the slope is not smooth, other diversion points can still work normally, improving the reliability of the system.

[0039] Working principle: Before installation, according to the size of each component and the actual situation of the slope 10, relevant trenches need to be dug at the top and bottom of the slope 10. The top trench can be used to install the fixing trench 20, and the bottom trench is used to install the drainage channel 30 and the planting trough 40. At the same time, drainage pipes 22 and branch pipes 50 need to be laid inside the slope 10. After fixing the pipe interfaces, the fixing trench 20 is connected to the drainage channel 30 and the drainage channel 30 and the planting trough 40 respectively through the first connection hole 23 and the second connection hole 33. Then, the extension hole 35 on the extension part 36 is used to connect the connection. By connecting multiple drainage channels 30 together, a slope protection structure can be laid for the entire slope. The structure is fixed to the soil slope 10 through fixing holes 21, 31, and 43. When extreme weather occurs, the water at the top of the slope will gather into the fixing groove 20 and enter the drainage channels 30 through the drainage pipe 22. The rainwater falling into the planting trough 40 will be decomposed by the dome structure of the circular frame 41. The impact water flow enters the drainage channel 30 through the drainage port 32, effectively preventing the entire structure from being impacted and displaced, thereby effectively protecting the internal nursery 11.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
