Description

Technical Field

[0001] This invention relates to the field of road drainage technology, and in particular to a rapid three-dimensional drainage system for roads prone to flooding. Background Technology

[0002] Urban flooding refers to the phenomenon of water accumulation in cities caused by heavy or continuous rainfall exceeding the city's drainage capacity. The main causes of urban flooding include: first, urbanization and impeded water vapor transport, leading to increased localized rainfall; second, inadequate drainage systems, with urban planning lagging behind development, resulting in existing drainage systems unable to meet current demands; and third, high rates of surface hardening, increasing surface runoff and making low-lying areas prone to flooding. The harm caused by urban flooding is immeasurable. At best, it causes traffic paralysis, hinders travel, or triggers disease outbreaks and water pollution; at worst, it threatens people's lives and property and affects social stability.

[0003] The existing road drainage system mainly relies on the drain outlets on both sides of the road. Rainwater flows from the drain outlets on both sides of the road into the drainage ditch. However, because the existing drain outlets have large openings, road debris can easily enter the drain outlets, causing blockages and hindering road drainage. Every time the rainy season is about to arrive, large-scale dredging of the drainage ditch and drain outlet is required to keep the drainage smooth, which is costly. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid three-dimensional drainage system for roads prone to flooding. The system adopts a multi-stage, automatic, and three-dimensional adjustable drainage system, which has better drainage capacity during heavy rain or storms, and is less prone to blockage by debris. It also eliminates the need for frequent dredging, thus reducing dredging costs.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A rapid three-dimensional drainage system for roads prone to flooding includes a driving lane and sidewalks on both sides of the driving lane. The driving lane includes a central ordinary pavement layer and permeable concrete pavement layers on both sides of the ordinary pavement layer. A permeable concrete base layer is provided at the lower end of the permeable concrete pavement layer, and a water diversion ditch is provided at the lower end of the permeable concrete base layer. A drainage ditch is provided below the sidewalk, and multiple diversion ditches connected to the drainage ditch are provided outward from the water diversion ditch.

[0007] Multiple installation slots are provided along the length of the permeable concrete pavement layer, extending downwards. A permeable mesh ring is positioned at the upper end of each installation slot. A sliding sleeve is located on the inner side of the permeable mesh ring, and an annular lifting column is slidably connected within the sliding sleeve. A permeable mesh drainage column is slidably connected to the inner side of the annular lifting column, remaining in its original position. An annular water-receiving groove is connected to the bottom of the annular lifting column, located outside the sliding sleeve. The inner ring of the annular water-receiving groove is slidably connected to the outer wall of the sliding sleeve. Multiple drainage holes are provided at the bottom. A ring of permeable concrete is provided inside the annular water receiving groove. A drainage pipe is provided downward at the lower end of the mesh drainage column and is slidably connected to the inner ring of the annular lifting column. The lower end of the drainage pipe passes downward through the permeable concrete base and communicates with the water diversion ditch. A support ring is provided in the middle of the drainage pipe. A support spring is provided between the support ring and the annular lifting column, which is fitted with the drainage pipe. When no external force is applied, the support spring makes the upper end of the annular lifting column flush with the permeable mesh ring.

[0008] By adopting the above technical solution, during light rain, the water on the road surface drains to the permeable concrete pavement layers on both sides. The water gradually seeps down into the drainage ditch along the permeable concrete pavement layers and the permeable concrete base layer. The water also flows from the permeable mesh ring into the annular water receiving trough. The water in the annular water receiving trough flows out through the annular permeable concrete and the drainage holes and then flows into the permeable concrete base layer. From the permeable concrete base layer, it seeps down into the drainage ditch. If the drainage of the annular water receiving trough is greater than the inflow, there will never be any water accumulation in the annular water receiving trough. Therefore, the annular water receiving trough will not cause the annular lifting column to move down. Finally, the water in the drainage ditch flows into the drainage ditch.

[0009] During heavy rain or storms, the inflow of water into the annular water receiving trough exceeds its drainage capacity, causing water to gradually accumulate inside. As the weight of the accumulated water increases, it causes the annular lifting column to move downwards, exposing the mesh drainage column. The accumulated water then enters the sliding sleeve and quickly flows through the mesh drainage column into the drainage pipe, rapidly draining into the irrigation ditch and finally into the drainage ditch. This achieves a two-stage, three-dimensional drainage system, increasing drainage capacity and preventing urban flooding. After the rain stops and drainage ends, the accumulated water in the annular water receiving trough is gradually drained. With the weight reduced, the annular lifting column gradually moves upwards under the action of the supporting spring, retracting the mesh drainage column into its interior. During the upward movement, it also pushes out any debris or debris that has entered the sliding sleeve, preventing blockages.

[0010] A further feature of the present invention is that: the upper sidewall of the sliding sleeve is provided with a plurality of first limiting holes; the outer side of the upper part of the annular lifting column is provided with a plurality of second limiting holes corresponding one-to-one with the first limiting holes; the upper sidewall of the sliding sleeve is provided with a plurality of limiting pieces corresponding one-to-one with the first limiting holes and in the shape of an inverted L; a sliding hole is provided through the vertical section of the limiting piece; the sliding hole is slidably connected to a limiting shaft facing the corresponding first limiting hole and the second limiting hole; a stop bar is provided near the outer wall of the sliding sleeve on the limiting shaft; and a limiting spring sleeved on the limiting shaft is provided between the stop bar and the limiting piece.

[0011] A lightweight floating ring is movably disposed within the annular water receiving trough. The upper end of the lightweight floating ring is provided with multiple lightweight connecting blocks that correspond one-to-one with the limiting shaft. The upper end of each lightweight connecting block is provided with two inclined spreading bars located on the left and right sides of the corresponding limiting shaft, respectively. The inclined spreading bars are located between the stop bar and the sliding sleeve. When the inclined spreading bars move upward, they drive the stop bar to compress the spring, causing the limiting shaft to be pulled out from the first limiting hole and the second limiting hole.

[0012] By adopting the above technical solution, as the water in the annular water receiving tank increases, the water pushes the lightweight floating ring upward, causing the inclined support bar to push the stop bar to compress the spring, thus pulling the limiting shaft out of the first and second limiting holes. The annular lifting column then loses its fixation and can slide up and down. After drainage is completed, the water in the annular water receiving tank gradually decreases, causing the annular lifting column to move upward. When it rises to the point where the second limiting hole is aligned with the first limiting hole, the limiting shaft slides into the first and second limiting holes, restricting the annular lifting column to prevent it from being pressed down and causing an accident when vehicles or pedestrians pass by.

[0013] A further feature of the present invention is that both the lightweight floating ring and the lightweight connecting block are hollow plastic.

[0014] A further feature of the present invention is that the gaps in the permeable concrete base layer are larger than the gaps in the permeable concrete pavement layer.

[0015] A further provision of the present invention is that the bottom of the water diversion ditch is inclined toward the drainage ditch.

[0016] A further feature of the present invention is that the inner wall of the sliding sleeve is provided with multiple vertical limiting strips, and the outer wall of the annular lifting column is provided with multiple vertical limiting grooves corresponding one-to-one with the vertical limiting strips.

[0017] A further feature of the present invention is that: a retaining ring is provided inwardly for the permeable mesh ring, and an annular groove that cooperates with the retaining ring is provided at the upper edge of the annular lifting column.

[0018] A further feature of the present invention is that the upper end of the mesh drainage column is sealed, and the sidewall of the mesh drainage column is composed of several vertical strips distributed in a circle.

[0019] A further provision of the present invention is that the sidewalk has a manhole opening communicating with the drainage ditch, and the manhole opening is detachably connected to a manhole cover.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Firstly, this invention utilizes permeable concrete on both sides of the road for drainage during light rain, and during heavy rain or storms, the ring-shaped lifting column automatically descends to expose the mesh drainage column for three-dimensional drainage. Combined with the permeable concrete, it achieves multi-stage and three-dimensional drainage, increasing the road's rapid drainage capacity and preventing waterlogging.

[0022] Secondly, the permeable concrete drainage system of this invention does not require drainage outlets, and will not be blocked by road debris. During light rain, the perforated drainage column is retracted into the annular lifting column, preventing debris from entering and causing blockages. After the perforated drainage column finishes draining, the annular lifting column can push out any debris that has entered the sliding sleeve, making it less likely for the perforated drainage column to become blocked. It is less likely for road debris to affect drainage capacity, and a large amount of debris will not enter the drainage ditch, greatly reducing the number of times the drainage ditch needs to be dredged and lowering dredging costs.

[0023] Thirdly, the mesh drainage column is at the same height as the road surface. When draining water, the mesh drainage column opens downwards, so there will be no protrusion of the mesh drainage column affecting vehicle driving and pedestrian traffic. In addition, the ring-shaped rising column will not descend when the upper surface is under pressure, preventing the ring-shaped rising column from descending and causing accidents when vehicles or pedestrians pass by.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0033] Example, refer to Figure 1-5A rapid three-dimensional drainage system for roads prone to waterlogging includes a driving lane 1 and sidewalks 2 on both sides of the driving lane 1. A green belt 21 is also located between the sidewalks 2 and the driving lane 1. The driving lane 1 includes a central ordinary pavement layer 11 and permeable concrete pavement layers 12 on both sides of the ordinary pavement layer 11. A permeable concrete base layer 3 is provided at the lower end of the permeable concrete pavement layer 12. The gaps in the permeable concrete base layer 3 are larger than the gaps in the permeable concrete pavement layer 12. The gaps in the permeable concrete pavement layer 12 are relatively smaller, which makes the pavement stronger. The gaps in the permeable concrete base layer 3 are larger, which makes its drainage capacity better. A water diversion ditch 31 is provided at the lower end of the permeable concrete base layer 3, and a drainage ditch 22 is provided below the sidewalk 2. The bottom of the water diversion ditch 31 is inclined towards the drainage ditch 22, so that the sediment caused by the muddy water in the water diversion ditch 31 can be more easily discharged into the drainage ditch 22. Multiple guide ditches 32 connected to the drainage ditch 22 are provided outward from the water diversion ditch 31. The sidewalk 2 has a manhole (not shown) connected to the drainage ditch 22. The manhole is detachably connected to a manhole cover 23, which can be used to inspect or clean the drainage ditch 22.

[0034] Multiple installation slots 13 are provided along the length of the permeable concrete pavement layer 12, penetrating downwards. A permeable mesh ring 4 is provided at the upper end of the installation slot 13. A sliding sleeve 41 is provided downwards on the inner side of the permeable mesh ring 4. A ring-shaped lifting column 5 is slidably connected inside the sliding sleeve 41. The ring-shaped lifting column 5 has a hollow structure. Three vertical limiting strips 42 are provided on the inner wall of the sliding sleeve 41. Three vertical limiting grooves 51 are provided on the outer wall of the ring-shaped lifting column 5, which correspond one-to-one with the vertical limiting strips 42. The cooperation between the vertical limiting strips 42 and the vertical limiting grooves 51 can prevent the ring-shaped lifting column 5 from rotating during the up and down movement. A retaining ring 43 is provided inwardly on the permeable mesh ring 4. An annular groove 52 that matches the retaining ring 43 is opened downward at the upper edge of the annular lifting column 5. A permeable mesh drainage column 6 is slidably connected to the inner side of the annular lifting column 5. The upper end of the permeable mesh drainage column 6 is sealed. The side wall of the permeable mesh drainage column 6 is composed of several vertical strips distributed in a circle. There are gaps between the vertical strips to prevent debris from entering while draining water. The permeable mesh drainage column 6 remains in place and does not rise or fall.

[0035] The bottom of the annular lifting column 5 is connected to an annular water receiving groove 53 located outside the sliding sleeve 41. The bottom of the annular water receiving groove 53 is flush with the bottom of the annular lifting column 5. The inner ring of the annular water receiving groove 53 is slidably connected to the outer wall of the sliding sleeve 41. When the annular water receiving groove 53 is filled with water and its weight increases, it drives the annular lifting column 5 to descend. The bottom of the annular water receiving groove 53 has multiple drainage holes 54. A ring of permeable concrete 55 is set inside the annular water receiving groove 53, so that the annular water receiving groove 53 has a certain drainage capacity. When the drainage capacity is less than the water intake capacity, it is heavy rain or rainstorm. The lower end of the mesh drainage column 6 is provided with a drainage pipe 61 that is slidably connected to the inner ring of the annular lifting column 5. The lower end of the drainage pipe 61 passes through the permeable concrete base layer 3 and connects to the water diversion ditch 31. A support ring 62 is provided in the middle of the drainage pipe 61. A support spring 7 is provided between the support ring 62 and the annular lifting column 5 to cover the drainage pipe 61. An inner sleeve 71 is provided on the edge of the support ring 62 to cover the support spring 7. The lower end of the annular lifting column 5 is provided with an outer sleeve 72 that covers the inner sleeve 71 and is slidably connected to it. When no external force is applied, the support spring 7 makes the upper end of the annular lifting column 5 flush with the permeable mesh ring 4.

[0036] The upper side wall of the sliding sleeve 41 is provided with three first limiting holes 44. The outer side of the upper part of the annular lifting column 5 is provided with three second limiting holes 56 corresponding to the first limiting holes 44. The upper side wall of the sliding sleeve 41 is provided with three limiting pieces 8 that are inverted L-shaped and correspond to the first limiting holes 44. A sliding hole (not shown) is provided through the vertical section of the limiting piece 8. A limiting shaft 81 is slidably connected to the sliding hole and is directly opposite to the first limiting hole 44 and the second limiting hole 56. A stop bar 82 is provided near the outer wall of the sliding sleeve 41 on the limiting shaft 81. A limiting spring 83 is provided between the stop bar 82 and the limiting piece 8 and is sleeved on the limiting shaft 81.

[0037] A lightweight floating ring 9 is movably installed inside the annular water receiving tank 53. The lightweight floating ring 9 also has three vertical limiting grooves 51. The inner wall of the annular water receiving tank 53 has three vertical limiting bars 42 corresponding to the vertical limiting grooves 51. The upper end of the lightweight floating ring 9 has three lightweight connecting blocks 91 corresponding to the limiting shafts 81. Both the lightweight floating ring 9 and the lightweight connecting blocks 91 are made of hollow plastic, or possibly foam material. The upper end of each lightweight connecting block 91 has two connecting bars located opposite each other. The inclined support bars 92 on both sides of the limiting shaft 81 are located between the stop bar 82 and the sliding sleeve 41. When the inclined support bars 92 move upward, they drive the stop bar 82 to compress the spring, causing the limiting shaft 81 to be pulled out from the first limiting hole 44 and the second limiting hole 56. When the limiting shaft 81 is inserted into the first limiting hole 44 and the second limiting hole 56, the annular lifting column 5 is blocked and cannot move. When the upper surface of the annular lifting column 5 is pressed, it will not descend, so that it will not descend and cause accidents when vehicles or pedestrians walk by.

[0038] Working principle: When it rains lightly, the water on the road surface drains to the permeable concrete pavement layer 12 on both sides. The water gradually seeps down into the drainage ditch 31 along the permeable concrete pavement layer 12 and the permeable concrete base layer 3. The water also flows from the permeable mesh ring 4 into the annular water receiving trough 53. The water in the annular water receiving trough 53 flows out through the annular permeable concrete 55 and the leakage hole 54 and then flows into the permeable concrete base layer 3. From the permeable concrete base layer 3, it seeps down into the drainage ditch 31. If the drainage of the annular water receiving trough 53 is greater than the inflow, there will never be any water accumulation in the annular water receiving trough 53. Therefore, the annular water receiving trough 53 will not cause the annular lifting column 5 to move down. Finally, the water in the drainage ditch 31 flows into the drainage ditch 22.

[0039] During heavy rain or storms, the inflow of water into the annular water receiving trough 53 exceeds its drainage capacity, causing water to gradually accumulate inside. This water pushes the lightweight floating ring 9 upwards, causing the inclined support bar 92 to push the stop bar 82 to compress the spring. This pulls the limiting shaft 81 out of the first limiting hole 44 and the second limiting hole 56, allowing the annular lifting column 5 to slide up and down without being fixed. As the water accumulates and the annular water receiving trough 53 becomes heavier, it causes the annular lifting column 5 to move downwards, exposing the mesh drainage column 6. The accumulated water enters the sliding sleeve 41 and quickly flows through the mesh drainage column 6 into the drain pipe 61, then rapidly flows into the water diversion ditch 31, and finally into the drainage channel. The drainage ditch 22 realizes two-stage three-dimensional drainage, increases drainage capacity, and prevents urban flooding. After the rain stops and drainage ends, the water in the annular water receiving trough 53 is gradually drained. With the weight reduced, under the action of the support spring 7, the annular lifting column 5 gradually moves upward and takes the mesh drainage column 6 into its interior. During the rising process, it can also push out the garbage and debris that have entered the sliding sleeve 41 to prevent blockage. When the second limit hole 56 is aligned with the first limit hole 44, the limit shaft 81 slides into the first limit hole 44 and the second limit hole 56 to restrict the annular lifting column 5 and prevent it from falling under pressure.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
