Description

Technical Field

[0001] This application relates to the field of drainage device technology, specifically to an integrated prefabricated drainage device. Background Technology

[0002] Rainy seasons are often characterized by heavy rainfall. As rainfall increases, the soil piles at spoil heaps or open-pit mines are easily loosened and slid due to rainwater erosion, leading to landslides, soil collapses, mine collapses, and other dangers that seriously endanger people's lives. It is evident that if the soil piles at spoil heaps or the water accumulated in open-pit mines are not drained in time, it will endanger people's lives and cause the loss of mineral resources. Summary of the Invention

[0003] In view of the technical problems existing in the background art, this application provides an integrated prefabricated drainage device with simple structure and convenient operation. It can filter impurities in the water flow and discharge the water flow into the corresponding ditch through the drainage pipe, so as to successfully intercept and drain water and prevent water accumulation.

[0004] This application provides an integrated prefabricated drainage device, installed in a drainage ditch, including a filter unit and a drain pipe arranged vertically, and reinforcing units spaced apart on the outside of the drain pipe; the filter unit includes a housing and a filter assembly installed in the housing, the filter assembly including coarse gravel and fine gravel arranged on both sides of the coarse gravel, the drain pipe is embedded in the bottom plate of the housing and located below the coarse gravel; the portion of the drain pipe embedded in the housing is provided with a third water-permeable hole.

[0005] In the technical solution of this application embodiment, by setting a filtration unit, the impurities in the water flow are filtered by the synergistic interaction of fine and coarse gravel to prevent particulate matter from seeping into the drain pipe and clogging it; by setting a third permeable hole in the part of the drain pipe embedded in the box, the water flow is discharged into the drain pipe, and the lower half of the drain pipe without holes serves as the main channel for water flow, smoothly discharging the water filtered by the filtration unit into the corresponding ditch. The water accumulation in the ditch does not affect the spoil heap or open mine, thus successfully achieving water interception and drainage and preventing water accumulation; by setting a reinforcing unit, the drain pipe is supported, reducing the pressure of coarse gravel on the drain pipe and protecting the drain pipe.

[0006] In some embodiments, the sidewall of the housing includes a first reverse filter plate group and a second reverse filter plate group disposed between the first reverse filter plate group; the first reverse filter plate group is provided with a first water permeable hole, and the second reverse filter plate group is provided with a second water permeable hole; the coarse gravel is disposed between the second reverse filter plate group, and the fine gravel is disposed between the first reverse filter plate group and the second reverse filter plate group.

[0007] In this embodiment, the coarse and fine gravel particles provide support for the first and second reverse filter plate groups, preventing excessive water flow from crushing the tank. Water-permeable holes are provided on the first and second reverse filter plate groups, allowing water to flow smoothly through the filter units and into the drain pipe.

[0008] In some embodiments, the diameter of the first permeable hole is 8-12 mm, the row spacing of the first permeable hole and the spacing between adjacent first permeable holes in each row is 20-30 mm; the diameter of the second permeable hole is 18-22 mm, the row spacing of the second permeable hole and the spacing between adjacent second permeable holes in each row is 40-60 mm.

[0009] In this embodiment, by setting the first permeable hole as a small-diameter, high-density hole and the second permeable hole as a large-diameter, low-density hole, the water entering the integrated prefabricated drainage device from both sides first flows through the first permeable hole to filter impurities before entering the tank, thus preventing fine gravel, the second permeable hole, and coarse gravel from being blocked.

[0010] In some embodiments, the top plate of the enclosure includes a plurality of spaced reinforcing ribs, with the spacing between adjacent reinforcing ribs being 0.4-0.6m.

[0011] In this embodiment, by setting reinforcing ribs, the housing is reinforced to prevent it from being crushed by the water flow. At the same time, the appropriate spacing between adjacent reinforcing ribs ensures that the water flow can smoothly enter the filter unit.

[0012] In some embodiments, the reinforcing unit includes four reinforcing plates; two of the reinforcing plates are disposed inside the housing, and the other two reinforcing plates are disposed outside the housing.

[0013] In this embodiment, two reinforcing plates are installed inside the box to protect the drain pipe and prevent coarse gravel from flattening or damaging it due to gravity; two reinforcing plates are installed outside the box to protect the lower surface of the drain pipe and prevent it from being flattened or damaged.

[0014] In some embodiments, the spacing between adjacent reinforcing units is 0.2-0.3m.

[0015] In this embodiment, by setting the spacing between adjacent reinforcing units within an appropriate range, the drainage pipe is protected while ensuring that water flows into the drainage pipe through the third permeable hole.

[0016] In some embodiments, the first permeable holes in adjacent rows are staggered; the second permeable holes in adjacent rows are staggered.

[0017] In this embodiment, arranging the first and second water-permeable holes in a rhomboid shape facilitates the rapid and smooth passage of water.

[0018] In some embodiments, the diameter of the third permeable hole is 10-15 mm, and the row spacing of the third permeable holes and the spacing between adjacent third permeable holes in each row is 30-50 mm.

[0019] In this embodiment, by reasonably setting the aperture and spacing of the third permeable hole, the water flow is ensured to pass smoothly through the third permeable hole while ensuring the strength of the drainage pipe.

[0020] In some embodiments, the upper surface of the filter assembly is provided with a filter screen.

[0021] In this embodiment, a filter screen is provided on the upper surface of the filter assembly to achieve preliminary filtration of the water flow and prevent the filter unit and drain pipe from being blocked.

[0022] In some embodiments, the inner wall of the drain pipe is provided with a water-permeable cloth.

[0023] In this embodiment, by providing a water-permeable cloth on the inner wall of the drain pipe, the water flowing into the drain pipe is further filtered to prevent it from clogging the drain pipe.

[0038] During the rainy season, as rainfall increases, it not only damages roads and severely affects people's travel, but also easily causes the danger of landslides, endangering people's lives and damaging buildings on top of the landslides.

[0039] To address the technical problem of untimely drainage damaging people's travel, safety, and buildings, this application provides an integrated prefabricated drainage device. This device incorporates a filtration unit that utilizes the synergistic effect of fine and coarse gravel to filter impurities in the water flow, preventing particulate matter from seeping into and clogging the drainage pipe. A third permeable hole is provided in the portion of the drainage pipe embedded in the casing, allowing water to flow into the pipe. The lower, unperforated portion of the drainage pipe serves as the main water channel, smoothly discharging the filtered water into a corresponding ditch. Water accumulation in this ditch does not affect spoil heaps or open-pit mines, effectively achieving water interception and drainage, and preventing water accumulation. A reinforcing unit supports the drainage pipe, reducing the pressure exerted by coarse gravel on it and protecting the drainage pipe.

[0040] Please refer to Figures 1 to 5 This is a schematic diagram of the structure of an integrated prefabricated drainage device 100 provided in the embodiment of this application. The integrated prefabricated drainage device 100 is disposed in a drainage ditch and includes a filter unit 1 and a drain pipe 2 disposed vertically and a reinforcing unit 3 disposed at intervals on the outside of the drain pipe 2. The filter unit 1 includes a box 11 and a filter assembly disposed in the box 11. The filter assembly includes coarse gravel 12 and fine gravel 13 disposed on both sides of the coarse gravel 12. The drain pipe 2 is embedded in the bottom plate of the box 11 and is located below the coarse gravel 12. The portion of the drain pipe 2 embedded in the box 11 is provided with a third water permeable hole 21.

[0041] In the technical solution of this application embodiment, a filter unit 1 is set to filter impurities in the water flow to prevent particulate matter from seeping into the drain pipe 2 and clogging it. The filter unit 1 also provides support for the housing 11 to prevent it from being deformed by the impact of the water flow. By setting fine gravel 13 on both sides of coarse gravel 12, when the water flow enters from both sides of the integrated prefabricated drainage device 100, it first passes through the fine gravel 13 and then through the coarse gravel 12. The strong filtering effect of the fine gravel 13 on the water flow can prevent the coarse gravel from entering. 12 is blocked, and the fine gravel 13 can prevent the backflow of water in the coarse gravel 12; by setting a third permeable hole 21 in the part of the drain pipe 2 embedded in the box 11, water is discharged into the drain pipe 2. The lower half of the drain pipe 2 without holes serves as the main channel for water flow, and the water filtered by the filter unit 1 is smoothly discharged into the corresponding ditch to prevent water accumulation; by setting a reinforcing unit 3, the drain pipe 2 is supported, reducing the pressure of the coarse gravel 12 on the drain pipe 2, and playing a role in protecting the drain pipe 2. Specifically, in use, an excavator is used to dig a drainage ditch at the location where water interception and drainage are required. The depth and width of the drainage ditch are not less than the depth and width of the integrated prefabricated drainage device 100. The sidewalls of the drainage ditch are designed with a certain slope to facilitate water flow into the integrated prefabricated drainage device 100. The integrated prefabricated drainage device 100 is placed in the drainage ditch. After the water is filtered and impurities are removed by the filter unit 1, it enters the drainage pipe 2 through the third permeable hole 21 and then enters the sewer, thus successfully achieving water interception and drainage. The water flow in the drainage pipe 2 has a certain velocity. When a small amount of unfiltered mud enters the drainage pipe 2, the flushing effect of the water flow can also play a role in clearing silt. In addition, by increasing the slope of the sidewalls of the drainage ditch, the water flows quickly into the integrated prefabricated drainage device 100, which can also prevent mud from entering the integrated prefabricated drainage device 100 to a certain extent. The integrated prefabricated drainage device 100 of this application enables mass production, rapid assembly, and efficient interception and drainage. Its length is 1-2m, and several integrated prefabricated drainage devices 100 can be spliced ​​together according to the length of the drainage ditch. When the drainage ditch is a blind ditch, holes need to be drilled on both the top and bottom sides for installation of the integrated prefabricated drainage device 100; when the drainage ditch is an open ditch, only the top needs to be drilled for installation.

[0042] Furthermore, in the embodiments of this application, such as Figure 1 As shown, the side wall of the housing 11 includes a first filter plate assembly 14 and a second filter plate assembly 15 disposed between the first filter plate assembly 14; as Figure 5 As shown, the first filter plate assembly 14 is provided with a first water permeable hole 141, such as... Figure 4As shown, the second filter plate group 15 is provided with a second water permeable hole 151; coarse gravel 12 is disposed between the second filter plate group 15, and fine gravel 13 is disposed between the first filter plate group 14 and the second filter plate group 15.

[0043] In the technical solution of this application embodiment, coarse gravel 12 is placed between the second filter plate group 15 to support the second filter plate group 15; fine gravel 13 is placed between the first filter plate group 14 and the second filter plate group 15 to support both the first filter plate group 14 and the second filter plate group 15, preventing excessive water flow from crushing the tank 11. A first water permeable hole 141 is provided on the first filter plate group 14, and a second water permeable hole 151 is provided on the second filter plate group 15, allowing water from both sides to flow smoothly through the filter unit 1 and into the drain pipe 2.

[0044] Furthermore, in the embodiments of this application, such as Figure 5 As shown, the diameter of the first permeable hole 141 is 8-12 mm, preferably 10 mm. The row spacing of the first permeable holes 141 and the spacing between adjacent first permeable holes 141 in each row are both 20-30 mm, preferably 25 mm. Figure 4 As shown, the diameter of the second permeable hole 151 is 18-22 mm, preferably 20 mm. The row spacing of the second permeable holes 151 and the spacing between adjacent second permeable holes 151 in each row are both 40-60 mm, preferably 50 mm. That is, the first permeable hole 141 has a small diameter and high pore density, while the second permeable hole 151 has a large diameter and low pore density.

[0045] In the technical solution of this application embodiment, by setting the first permeable hole 141 as a hole with a small pore size and high density, and the second permeable hole 151 as a hole with a large pore size and low density, the water entering the integrated prefabricated drainage device 100 from both sides first flows through the first permeable hole 141 to filter impurities before entering the box 11, preventing fine gravel 13, the second permeable hole 151 and coarse gravel 12 from being blocked, and the second permeable hole 151 has a larger pore size, so that the water flows smoothly.

[0046] Furthermore, in the embodiments of this application, such as Figure 1 As shown, the top plate of the housing 11 includes several spaced reinforcing ribs 16, with the spacing between adjacent reinforcing ribs 16 being 0.4-0.6m, preferably 0.5m. The reinforcing ribs 16 are connected to the upper surfaces of both the first filter plate group 14 and the second filter plate group 15.

[0047] In the technical solution of this application embodiment, by setting reinforcing ribs 16, the box 11 is reinforced to prevent it from being crushed by water flow. At the same time, the spacing between adjacent reinforcing ribs 16 is 0.4-0.6m. The appropriate spacing can ensure that the water flow can smoothly enter the filter unit 11.

[0048] Furthermore, in the embodiments of this application, such as Figure 1 As shown, the reinforcing unit 3 includes four reinforcing plates 31; two reinforcing plates 31 are disposed inside the housing 11, and the other two reinforcing plates 31 are disposed outside the housing 11.

[0049] In the technical solution of this application embodiment, two reinforcing plates 31 are provided inside the housing 11 to protect the drainage pipe 2 and prevent the coarse gravel 12 from flattening or damaging the drainage pipe 2 due to gravity. By providing two reinforcing plates 31 on the outside of the housing 11, not only is the lower surface of the drainage pipe 2 protected from being flattened or damaged, but the integrated prefabricated drainage device 100 can also be installed more stably in the drainage ditch.

[0050] Furthermore, in the embodiments of this application, the spacing between adjacent reinforcing units 3 is 0.2-0.3m, preferably 0.25m.

[0051] In the technical solution of this application embodiment, by setting the spacing between adjacent reinforcing units 3 in the range of 0.2-0.3m, the drainage pipe 2 is protected while ensuring that water flows into the drainage pipe 2 through the third permeable hole 21.

[0052] Furthermore, in the embodiments of this application, such as Figure 5 As shown, the first permeable holes 141 in adjacent rows are staggered; as Figure 4 As shown, the second permeable holes 151 in adjacent rows are staggered, that is, the first permeable hole 141 and the second permeable hole 151 are both arranged in a rhombus shape.

[0053] In the technical solution of this application embodiment, by arranging the first water-permeable hole 141 and the second water-permeable hole 151 in a rhomboid shape, it is beneficial for water to flow quickly and smoothly.

[0054] Furthermore, in this embodiment, the diameter of the third permeable hole 21 is 10-15mm, the row spacing of the third permeable holes 21 and the spacing between adjacent third permeable holes 21 in each row is 30-50mm, and the third permeable holes 21 are disposed between adjacent reinforcing plates 31.

[0055] In the technical solution of this application embodiment, by reasonably setting the aperture of the third permeable hole 21 and the spacing of the third permeable hole 21, the water flow is ensured to pass smoothly through the third permeable hole 21 while ensuring the strength of the drain pipe 2.

[0056] Furthermore, in this embodiment, a filter screen is provided on the upper surface of the filter assembly.

[0057] In the technical solution of this application embodiment, a filter screen is provided on the upper surface of the filter assembly to achieve preliminary filtration of the water flow and prevent the filter unit 1 and the drain pipe 2 from being blocked.

[0058] Furthermore, in this embodiment, a water-permeable cloth is provided on the inner wall of the drain pipe 2.

[0059] In the technical solution of this application embodiment, by providing a water-permeable cloth on the inner wall of the drain pipe 2, the water flowing into the drain pipe 2 is further filtered to prevent it from clogging the drain pipe 2.

[0060] The drainage pipe 2, the first reverse filter plate group 14, the second reverse filter plate group 15, the reinforcing rib 16, and the reinforcing plate 31 are all made of nylon fiber composite polyethylene material. The combination of plastic and chemical fiber with strong and bending resistance gives the integrated prefabricated drainage device 100 a certain strength.

[0061] Please refer to the following: Figures 1 to 5 According to one or more embodiments of this application, by setting a filter unit 1, the fine-grained gravel 13 and coarse-grained gravel 12 work together to filter impurities in the water flow to prevent particulate matter from seeping into the drain pipe 2 and clogging it; by setting a third permeable hole 21 in the part of the drain pipe 2 embedded in the box 11, the water flow is discharged into the drain pipe 2, and the lower half of the drain pipe 2 without holes serves as the main channel for water flow, so that the water flow filtered by the filter unit 1 can be smoothly discharged into the corresponding ditch, thus achieving water interception and drainage and preventing water accumulation; by setting a reinforcing unit 3, the drain pipe 2 is supported, reducing the pressure of the coarse-grained gravel 12 on the drain pipe 2 and protecting the drain pipe 2.
