[0001] This application relates to the field of drainage technology, and in particular to a roof drainage system for underground garages in sponge cities. Background Technology

[0002] The published patent CN217379545U discloses a roof drainage system for underground parking garages in sponge cities. The system includes a planting layer, a green area, and an underground parking garage. The planting layer has a green area on top and an underground parking garage at the bottom. An outdoor rainwater pipe system is installed inside the planting layer, with a rainwater sedimentation and filtration diversion device at the end. A rainwater collection pool is located on one side of the rainwater sedimentation and filtration diversion device. A waterproof protective layer is installed at the top of the underground parking garage, topped with a root-penetration-resistant waterproof membrane. A raised drainage board is laid on top of the root-penetration-resistant waterproof membrane, and blind drains are symmetrically arranged outside the raised drainage board. Permeable bricks are installed at the bottom of the planting layer. This roof drainage system for underground parking garages in sponge cities has strong drainage capacity, simple construction, low cost, effectively drains accumulated water, solves the problem of water accumulation, requires no maintenance, and has a long service life, comparable to the building's lifespan.

[0003] The drainage system for underground garage roofs in the aforementioned patent for sponge cities has a flat drainage board design. During drainage, the water cannot flow effectively to the blind ditch, which makes it easy for water to accumulate on the top of the drainage board, thus causing roof seepage, leaks, and damage to the roof.

[0004] Therefore, this application proposes a roof drainage system for underground parking garages in sponge cities. Utility Model Content

[0005] This application proposes a roof drainage system for underground parking garages in sponge cities to solve the problems mentioned in the background art. By designing the convex-concave drainage board as a layered surface with concave and convex surfaces, the convex surface area of ​​the drainage board is larger than the concave surface, making it difficult for water to accumulate on the convex-concave drainage board and effectively directing it to the concave surface, thereby accelerating drainage efficiency. By setting guide plates in the concave surface of the drainage board, with the sides of the guide plates being lower than the middle position, the water on the convex-concave drainage board can flow smoothly to the blind ditch, preventing water accumulation on the convex-concave drainage board. With long-term use, the convex-concave drainage board is not prone to rotting and seepage problems, thereby avoiding roof leaks and improving roof drainage performance.

[0006] To achieve the above objectives, this application adopts the following technical solution: A sponge city underground garage roof drainage system includes an underground garage, a planting layer, a green area, and a raised drainage board. The planting layer is located on top of the underground garage, and a green area is located on top of the planting layer. The raised drainage board is located between the underground garage and the planting layer. Permeable bricks are fixedly connected to the bottom of the planting layer, and a filter layer is located at the bottom of the permeable bricks. An elevated space is formed between the raised drainage board and the filter layer, thus forming an elevated layer.

[0007] In a preferred embodiment, the groove of the concave-convex drainage plate forms a drainage and venting channel, and a guide plate is provided inside the drainage and venting channel, with the two sides of the guide plate being lower than the middle position; By designing the convex-concave drainage board with a layered surface, the convex surface area is larger than the concave surface, making it less prone to water accumulation and allowing water to flow effectively to the concave surface, thus accelerating drainage efficiency. By installing guide plates within the concave surface of the drainage board, with the sides of the guide plates lower than the center, the water flow on the convex-concave drainage board can smoothly flow to the blind drain, preventing water accumulation. Long-term use also makes the convex-concave drainage board less prone to rotting and seepage, thus avoiding roof leaks and improving roof drainage performance, thereby enhancing the practicality of the device.

[0008] In a preferred embodiment, the top of the underground garage is provided with a waterproof protective layer, and a root-penetration resistant waterproof membrane is laid on top of the waterproof protective layer, with the root-penetration resistant waterproof membrane located at the bottom of the convex-concave drainage board; By laying root-penetration resistant waterproof membranes, excellent waterproof performance can be achieved, effectively preventing water penetration and protecting buildings from water damage. These membranes are usually made of polymer materials, with a dense texture and a low water vapor permeability coefficient, ensuring their excellent waterproof effect. Secondly, root-penetration resistant waterproof membranes can prevent plant roots from penetrating, which means that they can not only effectively prevent water penetration, but also withstand the penetration of plant roots, maintaining the integrity of the waterproof layer for a long time, while not affecting the normal growth of plants, thus improving the practicality of the installation.

[0009] In a preferred embodiment, two blind drains are symmetrically arranged on the outside of the convex and concave drainage board, and an outdoor rainwater pipe system is arranged inside the planting layer, and the outdoor rainwater pipe system is connected to the blind drains; By laying a raised drainage board on the waterproof protective layer to form an elevated space, the elevated layer forms a drainage and ventilation channel. Rainwater seeps down and flows into the blind ditch through the drainage and ventilation channel, thereby improving the practicality of the device.

[0010] In a preferred embodiment, a rainwater sedimentation and filtration diversion device is provided at the end of the outdoor rainwater pipe system, and the outdoor rainwater pipe system and the rainwater sedimentation and filtration diversion device are connected by a connecting pipe; By connecting to the outdoor rainwater pipe system through blind drains, the rainwater is guided through the connecting pipe into the rainwater sedimentation and filtration diversion device for sedimentation and filtration, thereby improving the practicality of the device.

[0011] In a preferred embodiment, a rainwater collection tank is provided on one side of the rainwater sedimentation and filtration diversion device, and the rainwater collection tank is connected by a flexible connecting pipe. Outdoor rainwater is guided into the rainwater sedimentation, filtration and diversion device through the connecting pipe. After treatment, the rainwater flows into the rainwater collection tank through the flexible connecting pipe, thereby improving the practicality of the device.

[0012] The beneficial effects of this application are: 1. The roof drainage system for underground garages in sponge cities is designed with a textured drainage board, where the convex surface of the drainage board is larger than the concave surface, so that water does not easily accumulate on the drainage board and flows effectively to the concave surface of the drainage board, thereby accelerating the drainage efficiency and greatly improving the practicality of the device. 2. This sponge city underground garage roof drainage system features a guide plate installed within the concave surface of the drainage board. The sides of the guide plate are lower than the middle position, allowing water to flow smoothly into the blind ditch on the concave-convex drainage board. This prevents water accumulation on the concave-convex drainage board and makes it less prone to rotting and seepage over long-term use, thus avoiding roof leaks, improving roof drainage efficiency, and greatly enhancing the practicality of the device.

The planting layer 2 is set on the top of the underground garage 1, and the green area 3 is set on the top of the planting layer 2. The raised drainage board 8 is set between the underground garage 1 and the planting layer 2. The bottom of the planting layer 2 is fixedly connected to a permeable brick 4, and the bottom of the permeable brick 4 is set with a filter layer 5. An elevated space is formed between the raised drainage board 8 and the filter layer 5, thus forming an elevated layer.

[0017] Reference Figure 1-4 The grooves of the convex-concave drainage board 8 form drainage and ventilation channels 9. Inside the drainage and ventilation channels 9, there are guide plates 10, with the two sides of the guide plates 10 lower than the middle position. By designing the convex-concave drainage board 8 as a layered surface with concave and convex surfaces, the convex surface area of ​​the drainage board is larger than the concave surface, so that the water flow on the convex-concave drainage board 8 is not easy to accumulate and flows effectively to the concave surface of the drainage board, thereby accelerating the drainage efficiency. By setting the guide plates 10 in the concave surface of the drainage board, with the two sides of the guide plates 10 lower than the middle position, the water flow on the convex-concave drainage board 8 can flow smoothly to the blind drain 11, and there is no water accumulation on the convex-concave drainage board 8. With long-term use, the convex-concave drainage board 8 is not easy to rot and leak, thereby avoiding roof leakage, improving the roof drainage effect, and thus improving the practicality of the device.

[0018] Reference Figure 1-4 The underground parking garage 1 is equipped with a waterproof protective layer 6 on top, and a root-penetration resistant waterproof membrane 7 is laid on top of the waterproof protective layer 6, with the root-penetration resistant waterproof membrane 7 located at the bottom of the convex and concave drainage board 8. By laying the root-penetration resistant waterproof membrane 7, it has excellent waterproof performance, effectively preventing water penetration and protecting the building from water damage. This membrane is usually made of polymer materials, with a dense texture and a low water vapor permeability coefficient, ensuring its excellent waterproof effect. Secondly, the root-penetration resistant waterproof membrane 7 can prevent plant roots from penetrating, which means that it can not only effectively prevent water penetration, but also withstand the penetration of plant roots, maintaining the integrity of the waterproof layer for a long time, while not affecting the normal growth of plants, thereby improving the practicality of the device.

[0019] Reference Figure 1-4Two blind drains 11 are symmetrically arranged on the outside of the convex drainage board 8. An outdoor rainwater pipe system 12 is installed inside the planting layer 2, and the outdoor rainwater pipe system 12 is connected to the blind drains 11. By laying the convex drainage board 8 on the waterproof protective layer 6 to form an elevated space, the elevated layer forms a drainage and ventilation channel 9. The infiltrated rainwater flows into the blind drains 11 through the drainage and ventilation channel 9, thereby improving the practicality of the device.

[0020] Reference Figure 1-2 The outdoor rainwater pipe system 12 is equipped with a rainwater sedimentation and filtration diversion device 14 at its end, and the outdoor rainwater pipe system 12 and the rainwater sedimentation and filtration diversion device 14 are connected by a connecting pipe 13. The rainwater pipe system 12 is connected to the outdoor rainwater pipe system 12 through a blind ditch 11, and the rainwater is guided into the interior of the rainwater sedimentation and filtration diversion device 14 through the connecting pipe 13 for sedimentation and filtration, thereby improving the practicality of the device.

[0021] Reference Figure 1-2 A rainwater collection tank 16 is provided on one side of the rainwater sedimentation and filtration diversion device 14, and the rainwater sedimentation and filtration diversion device 14 and the rainwater collection tank 16 are connected by a flexible connecting pipe 15. Outdoor rainwater is guided into the rainwater sedimentation and filtration diversion device 14 through the connecting pipe 13, and the treated rainwater flows into the rainwater collection tank 16 from the flexible connecting pipe 15, thereby improving the practicality of the device.

[0022] Working principle: The roof of the underground parking garage 1 is a green roof, and the roof waterproofing uses root-penetration resistant waterproof membrane 7. The roof drainage system adopts an organized drainage system. By laying a corrugated drainage board 8 on the waterproof protective layer 6 to form an elevated space, the elevated layer forms drainage and ventilation channels 9. Rainwater infiltrates through the drainage and ventilation channels 9 and flows into the blind drain 11. The blind drain 11 is connected to the outdoor rainwater pipe system 12 and is guided into the rainwater sedimentation, filtration and diversion device 14 through the connecting pipe 13. The treated rainwater flows from the flexible connecting pipe 15. The rainwater is collected in the rainwater collection tank 16. Once the rainwater collection tank 16 is filled with water, the rainwater is diverted into the municipal drainage network of the urban area. The drainage board has a transparent structural system, strong drainage capacity, simple construction, and low cost. It effectively drains accumulated water, solves the problem of water accumulation, requires no maintenance, has a long service life that can last as long as the building, and the open layer is connected to the atmosphere, which is conducive to plant growth. The infiltrated water is collected and reused, saving water resources and meeting the requirements of sponge city construction. It achieves the goals of environmental protection, water and energy conservation, and flood control and disaster relief.

[0023] This drainage system, by designing the convex-concave drainage board 8 as a layered surface with concave and convex sections, with the convex surface area being larger than the concave surface, prevents water from accumulating on the drainage board 8 and allows it to flow effectively to the concave surface, thereby accelerating drainage efficiency. By installing guide plates 10 inside the concave surface of the drainage board, with the sides of the guide plates 10 being lower than the middle position, the water on the convex-concave drainage board 8 can flow smoothly to the blind drain 11, preventing water accumulation on the drainage board 8. With long-term use, the convex-concave drainage board 8 is less prone to rotting and seepage problems, thus avoiding roof leaks and improving roof drainage performance.
