Description

Technical Field

[0001] This utility model relates to the field of slope drainage technology, specifically a drainage device for a mine ecological restoration backfill slope platform. Background Technology

[0002] During mining operations, topsoil stripping and slag filling create fill slopes with varying heights. These fill slopes are characterized by uneven soil and rock structure, high gravel content, loose structure, good permeability, and significant settlement and deformation. Under the influence of factors such as heavy rainfall, earthquakes, and human engineering activities, they are highly susceptible to instability, deformation, collapse, and damage, resulting in serious consequences.

[0003] A search revealed that this utility model, with authorized Chinese patent publication number CN 223305033 U, provides a drainage device for a mine ecological restoration fill slope platform, relating to the field of mine ecological restoration slope drainage technology. It includes: a fill slope, a soil drainage ditch, a clay layer, a drainage pipe, a geomembrane, and a soil water-retaining stalk; a soil drainage ditch is set on the inner side of the slope platform; a clay layer is set on the surface of the soil drainage ditch, and a drainage pipe is set on the surface of the clay layer; a geomembrane is set on the surface of the drainage pipe, extending towards the platform and the slope toe on both sides of the geomembrane, and a soil water-retaining stalk is set on the surface of the geomembrane extending to the platform. This utility model is convenient and quick to construct, has a simple structure, and can adapt to uneven settlement and deformation of mine fill slopes. Water on the surface of the fill slope can be collected in the drainage ditch at the slope toe and discharged in a timely manner, preventing the slope from being eroded and infiltrated by surface water, thus reducing the damage of surface water to vegetation and ensuring the effectiveness of mine ecological restoration.

[0004] The slope platform in the aforementioned patent still has certain shortcomings. As existing mine backfill slope platforms mostly rely on drainage channels for drainage, traditional drainage channels are mostly simple in structure and are easily covered by vegetation on the slope, thus losing their basic drainage function and easily leading to water accumulation on the slope, making them unsuitable for users' drainage needs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drainage device for a mine ecological restoration backfill slope platform. This device solves the problem that existing mine backfill slope platforms mostly rely on drainage channels for drainage. However, traditional drainage channels are often simple in structure and easily covered by vegetation on the slope, thus losing their basic drainage function and leading to water accumulation on the slope, making them unsuitable for users' drainage needs.

[0006] This utility model provides the following technical solution: a drainage device for a mine ecological restoration backfill slope platform, including a mine slope base, wherein a plurality of partition connecting plates are evenly arranged on the inclined surface of the mine slope base, and a drainage groove is opened at the top of each partition connecting plate. Each pair of partition connecting plates is connected by a fixed connecting plate, and two drainage holes are symmetrically arranged on the fixed connecting plate. A drainage protection component is provided at the top of each partition connecting plate.

[0007] The drainage protection assembly includes a top side support mesh disposed on the top side of the partition connecting plate. The ends of the top side support mesh are symmetrically provided with connection holes. The top sides of the partition connecting plate are symmetrically provided with side connecting strips. The sides of the side connecting strips are provided with mounting grooves. The bottom sides of the top side support mesh are symmetrically provided with side connecting plates. The ends of the side connecting plates are provided with mounting holes. The sides of the side connecting plates are provided with mounting slides. The mounting slides are slidably inserted into the mounting grooves.

[0008] Preferred technical solution 1: A connecting bolt is inserted between the mounting hole and the connecting hole, and a fixing nut is fitted onto the end of the connecting bolt.

[0009] Preferred technical solution 2: Several side water inlets are symmetrically opened on both sides of the partition connecting plate, and a soil filter screen is installed in each side water inlet.

[0010] Preferred technical solution 3: The top side surface of the top side support net is arc-shaped.

[0011] This solution enables the top side support net to better protect the top side of the drainage channel, preventing the drainage channel from being quickly covered by vegetation.

[0012] Preferred technical solution four: The longitudinal sections of both the mounting slide and the mounting groove are trapezoidal.

[0013] This solution ensures that the mounting strip will not easily fall off while sliding in the mounting groove.

[0014] Preferred technical solution five: all the side water inlets are connected to the drainage trough.

[0015] This design allows water flowing into the protective grid formed by the fixed connecting plate and the partition connecting plate to be discharged into the drainage trough through the side inlet.

[0016] Compared with the prior art, this utility model provides a drainage device for a mine ecological restoration backfill slope platform, which has the following beneficial effects: This utility model forms a backfill protection grid on the inclined surface of the mine slope base by setting several fixed connecting plates and partition connecting plates in an alternating manner, which facilitates backfill restoration for users. The top of the partition connecting plates is equipped with a drainage channel, and the sides of the partition connecting plates are equipped with several side water inlets, which allow rainwater to enter the drainage channel through the side water inlets and be quickly discharged. The top side of the drainage channel is supported and protected by a top side support net, which effectively prevents the rapid growth of vegetation from covering the drainage channel, ensuring the normal drainage function of the drainage channel and making it convenient for users.

[0023] Please see Figure 1-4 ,

[0024] Example 1: A drainage device for a mine ecological restoration backfill slope platform includes a mine slope base 1. Several partition connecting plates 2 are evenly arranged on the inclined surface of the mine slope base 1. Each partition connecting plate 2 has a drainage groove 3 at its top. Each pair of partition connecting plates 2 is connected by a fixed connecting plate 4. Two drainage holes 5 are symmetrically arranged on the fixed connecting plate 4. Each partition connecting plate 2 has a drainage protection component 6 at its top.

[0025] The drainage protection component 6 includes a top side support net 601 set on the top side of the partition connecting plate 2. The top side support net 601 has symmetrically opened connection holes 602 at both ends. The top of the partition connecting plate 2 has symmetrically arranged side connecting strips 603 on both sides. The side of each side connecting strip 603 has an installation groove 604. The bottom of the top side support net 601 has symmetrically arranged side connecting plates 605 on both sides. The end of each side connecting plate 605 has an installation hole 606. The side of each side connecting plate 605 has an installation slide 607. The installation slide 607 is slidably inserted into the installation groove 604. A connecting bolt 608 is inserted between the installation hole 606 and the connection hole 602. The end of the connecting bolt 608 is fitted with a fixing nut 609. The partition connecting plate 2 has several symmetrically opened side water inlets 610 on both sides. Each side water inlet 610 is provided with a soil filter screen 611.

[0026] Example 2: The difference between this example and Example 1 is that the top side surface of the top side support net 601 is arc-shaped.

[0027] This allows the top side support net 601 to better protect the top side of the drainage channel 3, preventing the drainage channel 3 from being quickly covered by vegetation.

[0028] Example 3: The difference between this example and Example 1 is that the longitudinal sections of both the mounting slide 607 and the mounting groove 604 are trapezoidal.

[0029] This ensures that the mounting slide 607 will not easily fall off when sliding in the mounting groove 604.

[0030] Example 4: The difference between this example and Example 1 is that the side water inlets 610 are all connected to the drainage trough 3.

[0031] This allows water flowing into the protective grid formed by the fixed connecting plate 4 and the partition connecting plate 2 to enter the drainage trough 3 through the side inlet 610 and be discharged.

[0032] In this embodiment, existing mine fill slope platforms mostly rely on drainage channels for drainage. However, traditional drainage channels are mostly simple in structure and are easily covered by vegetation on the slope, thus losing their basic drainage function and easily causing water accumulation on the slope, making them unsuitable for users' drainage needs.

[0033] In summary, during implementation, several partition connecting plates 2 and fixed connecting plates 4 are evenly arranged on the inclined surface of the mine slope base 1. The partition connecting plates 2 and fixed connecting plates 4 are staggered to form a protective grid, which facilitates the user to fill and repair the inclined side of the mine slope base 1. Drainage channels 3 are opened at the top of each partition connecting plate 2, and several side water inlets 610 are opened on both sides of the partition connecting plate 2. The combination of drainage channels 3 and side water inlets 610 can quickly and conveniently drain the accumulated water on the inclined surface of the mine slope base 1. The drainage holes 5 opened on the fixed connecting plates 4 can also be used to drain the accumulated water. The protective grid composed of fixed connecting plates 4 and partition connecting plates 2 can effectively prevent soil and water loss.

[0034] A drainage protection component 6 is also provided on the top side of the drainage ditch 3. The bottom of the top support net 601 in the drainage protection component 6 is provided with side connecting plates 605 on both sides. The side connecting plates 605 and the top support net 601 are connected by connecting bolts 608 inserted in the connecting holes 602 and the mounting holes 606. The side of the side connecting plate 605 is provided with a mounting slide 607. The mounting slide 607 is slidably inserted into the mounting groove 604 opened on the side connecting plate 603, so that the top support net 601 can be stably set at the top of the drainage ditch 3, providing support and protection for the top side of the drainage ditch 3. This can effectively prevent the top of the drainage ditch 3 from being covered by vegetation growth on the slope. The top support net 601 allows water to flow through and enter the drainage ditch 3, so that rainwater can be quickly discharged along the drainage ditch 3 on rainy days.

[0035] Furthermore, since the top side support net 601 is fixed to the top of the partition connecting plate 2 through the side connecting plate 605, the top side support net 601 is easier to disassemble and replace, which effectively improves the user's ability to replace and maintain the top side support net 601 and makes it more convenient for the user to use.
