[0031] Municipal drainage systems are a crucial component of urban infrastructure, primarily responsible for collecting and transporting rainwater and domestic sewage. The outfall structure is a key component of the urban drainage system, primarily used to collect and discharge rainwater. This outfall structure typically consists of a brick shaft with a square or circular cast iron overflow installed on top, connected to the site drainage pipe via a perforated pipe below, and ultimately discharged into the municipal stormwater pipeline. Rainwater easily washes debris such as mud, fallen leaves, and other debris from the ground into the outfall structure. However, due to the large gaps in the water grates of traditional outfall structures, pollutants in rainwater cannot be effectively intercepted, resulting in blockages within the rainwater structure that are difficult to clear, affecting the outfall structure's discharge capacity and easily causing urban waterlogging.

[0032] In order to solve the above problems, the present application proposes a drainage assembly.

[0033] See also Figures 1 to 4 In one embodiment of the present application, the drainage assembly includes a wellbore structure 1, a first filter structure 2 and a second filter structure 3. The wellbore structure 1 is provided with a plurality of penetration holes 11 on at least the side wall, and the penetration holes 11 pass through the side wall of the wellbore structure 1; the water outlet end of the wellbore structure 1 is used to connect to the municipal drainage pipe; the first filter structure 2 is covered on the water inlet end of the wellbore structure 1; the second filter structure 3 is erected in the wellbore structure 1, and the second filter structure 3 is provided with a plurality of sewage interception holes.

[0034] In the above structure, by setting a first filter structure 2 at the water inlet end of the well structure 1, rainwater passing through the first filter structure 2 can initially remove larger debris and garbage, preventing them from entering the interior of the well structure 1, thereby reducing the risk of blockage inside the drainage component; secondly, a second filter structure 3 is arranged in the well structure 1, and a plurality of sewage interception holes are provided on the second filter structure 3, so that rainwater can pass through the sewage interception holes smoothly, and smaller debris and pollutants can be further intercepted and collected by the second filter structure 3 to prevent them from entering the municipal drainage pipe; at the same time, the second filter structure 3 is easy to take out and perform regular cleaning and maintenance to maintain the drainage smoothness of the drainage component; in addition, a plurality of penetration holes 11 are provided on the side wall of the well structure 1, and the penetration holes 11 pass through the side wall of the well structure 1, so that rainwater can penetrate smoothly into the ground through the penetration holes 11, which can not only reduce the amount of water accumulation inside the well structure 1, but also promote the natural infiltration of rainwater and the replenishment of groundwater, thereby improving the discharge capacity of the drainage component.

[0035] It should be noted that the first filter structure 2 is also called bamboo strips, and the second filter structure 3 is also called a sewage interception basket. In addition, when the drainage component is in good drainage condition, the rainwater outside the drainage component first infiltrates through the biological retention facilities (such as vegetation-covered ditches, infiltration ditches, etc.), and uses the permeability of the soil to allow part of the rainwater to directly infiltrate into the ground, thereby reducing the surface runoff. The rainwater that fails to infiltrate through the biological retention facilities can enter the interior of the well structure 1 through the infiltration holes 11 on the well structure 1, thereby improving the rainwater collection efficiency, promoting the natural infiltration of rainwater, and reducing the risk of urban waterlogging.

[0036] In one embodiment, a raised grating-like structure 21 is formed on the top of the first filter structure 2, and a horizontal portion 22 is provided around the grating-like structure 21. The horizontal portion 22 abuts against the cover at the water inlet end. The horizontal portion 22 is provided around the grating-like structure 21 so that the first filter structure 2 can better abut against the water inlet end of the well structure 1. The first filter structure 2 is installed by abutting the horizontal portion 22 against the water inlet end, which can reduce the difficulty of construction. The horizontal portion 22 of the first filter structure 2 abuts against the water inlet end of the well structure 1, which can ensure that rainwater can effectively enter the interior of the well structure 1 for the next step of processing, and can also help prevent debris and garbage from directly entering the well, thereby protecting other structures inside the well. The grating structure 21 of the first filter structure 2 performs preliminary filtration on the rainwater. Larger debris and garbage are intercepted on the first filter structure 2, while the rainwater enters the wellbore through the gaps in the first filter structure 2; a raised grating structure 21 is provided on the top of the first filter structure 2, which can increase the strength and stability of the first filter structure 2, while providing a larger surface area for contact with rainwater; and the raised grating structure 21 helps to evenly distribute rainwater, reduce direct impact, and reduce the risk of the first filter structure 2 being blocked by debris.

[0037] In one embodiment, the drainage system further includes a plurality of compression members 4, which are provided on the horizontal portion 22. By providing the compression members 4 on the horizontal portion 22, the first filter structure 2 is fixed by the compression members 4, and the horizontal portion 22 abuts against the water inlet end of the wellbore structure 1. The compression members 4 can effectively compress the first filter structure 2, ensuring the tightness of the connection between the first filter structure 2 and the wellbore structure 1, and preventing debris from directly entering the interior of the wellbore structure 1. The compression members 4 can also enhance the overall stability of the first filter structure 2, especially under the action of wind or other external forces, to prevent the first filter structure 2 from shifting or being damaged. It should be noted that the compression members 4 can be made of pebbles or gravel when necessary. These natural materials have little impact on the environment and meet environmental protection requirements.

[0038] In one embodiment, the first filter structure 2 is made of polypropylene. The first filter structure 2 made of polypropylene can be recycled and reused after reaching its service life, reducing its impact on the environment and meeting environmental protection requirements. Polypropylene also has excellent durability and can maintain its performance during long-term use in natural environments. Polypropylene is particularly stable in water, being insoluble in water and having extremely low water absorption, thus ensuring excellent stability in humid environments. Furthermore, polypropylene has excellent mechanical properties, including tensile strength, compressive strength, and hardness, as well as outstanding rigidity and resistance to bending fatigue, enabling the first filter structure 2 to withstand the various physical stresses of daily use. Finally, polypropylene also has excellent processability and can be molded through methods such as injection molding and extrusion. This allows the first filter structure 2 to be designed into various shapes and structures as needed, facilitating large-scale production and installation. In summary, using recycled, environmentally friendly PP (polypropylene) as the material for the first filter structure 2 not only has excellent durability, corrosion resistance, and impact resistance, but is also easily recyclable and reusable, meeting environmental protection requirements.

[0039] In one embodiment, the hole cross-section of the sewage interception hole is smaller than the grid area of ​​the grating structure 21. After the rainwater passes through the grating structure 21 of the first filter structure 2 for coarse filtration to remove larger impurities and garbage, it is then filtered twice by the second filter structure 3, which can reduce the impurities entering the shaft structure 1, ensure that the rainwater entering the market drainage system is cleaner, and reduce the pollution of groundwater quality. Secondly, the second filter structure 3 can be cleaned regularly to remove trapped impurities and garbage, making maintenance work simpler and more efficient. It should be noted that the design of the sewage interception hole can adjust the pore size according to actual needs to adapt to different filtration requirements and environmental conditions.

[0040] In one embodiment, a flange portion 31 is provided around the edge of the opening of the second filter structure 3. The flange portion 31 is mounted on the edge of the opening at the water inlet end, so that the second filter structure 3 is suspended within the shaft structure 1. The flange portion 31 is mounted on the edge of the opening at the water inlet end, so that the second filter structure 3 is suspended within the shaft structure 1. This ensures that rainwater is filtered through the basket before flowing into the shaft, thereby effectively intercepting and collecting debris. In addition, the flange portion 31 serves as a support structure for the second filter structure 3, making it easy to install and disassemble the second filter structure 3, facilitating regular cleaning of trapped debris and making maintenance more convenient. It also ensures that the second filter structure 3 is stably suspended within the shaft structure 1, preventing displacement or overturning due to water flow impact or external forces.

[0041] In one embodiment, the flange portion 31 is provided with a retaining groove 311, into which the first filter structure 2 is snapped. The retaining groove 311 provides a stable fixing point for the first filter structure 2, allowing for quick assembly and disassembly of the filter structure 2, facilitating maintenance and replacement, and improving the maintainability of the system. This enhances the stability and durability of the entire system, prevents the filter structure 2 from shifting during use, and ensures its continued effective filtration.

[0042] In one embodiment, the well structure 1 is provided with a bottom wall having a plurality of infiltration holes 11 therein, the infiltration holes 11 extending through the bottom wall. The drainage assembly further includes a filter layer 5 disposed on the bottom wall. Rainwater undergoes secondary filtration within the well structure 1 through the filter material layer, further removing smaller suspended matter, silt, and other pollutants. This helps improve the quality of the rainwater and ensures that the rainwater ultimately flowing into the municipal drainage pipe is as clean as possible. In addition, by varying the aperture and number of infiltration holes 11, the speed at which rainwater enters the well can be adjusted, preventing a large amount of rainwater from directly impacting the bottom wall of the well structure 1 in a short period of time and reducing the impact on the filter layer 5. The infiltration holes 11 on the bottom wall allow rainwater to pass through the bottom wall and enter the municipal drainage system. The filter layer 5 disposed on the bottom wall facilitates regular cleaning or replacement of the filter layer 5 to maintain its filtration efficiency. In addition, the filter layer 5 can use activated carbon and sand as filter materials. Activated carbon has a strong adsorption capacity and can effectively remove organic matter, chlorine, odor and color in water. When activated carbon and sand are used in combination, the sand can first filter out larger particles, while the activated carbon can further remove smaller pollutants.

[0043] In one embodiment, the outer surface of the shaft structure 1 is wrapped with a geotextile layer. The geotextile has excellent air and water permeability, allowing water to flow through while effectively intercepting sand and soil loss, preventing fine soil particles from being carried away by water, maintaining soil stability, and reducing the risk of seepage damage. Furthermore, when subjected to external impact, the geotextile can decompose and diffuse concentrated stress, protecting the shaft structure 1 from impact damage and enhancing its stability and filtration effectiveness.

[0044] In one embodiment, a gravel layer 6 is provided on the outer periphery of the shaft structure 1, and the gravel layer 6 can play multiple roles such as filtering, drainage, and protection of the shaft structure 1; and when the gravel layer 6 is used in combination with a geotextile layer, the geotextile layer can serve as a filter layer 5 to prevent fine particles in the gravel layer 6 from entering the shaft structure 1. At the same time, the geotextile layer allows water to pass through, increasing the permeability of water to achieve optimal filtering, drainage and protection effects.

[0045] In one embodiment, the drainage system further includes a base 7, which is disposed at the bottom of the shaft structure 1. The base 7 is provided with a barrel pipe opening 71 and at least one drainage pipe opening 72. The barrel pipe opening 71 is connected to the water outlet of the shaft structure 1 and communicates with the drainage pipe opening 72. The drainage pipe opening 72 is used to connect to a municipal drainage pipe. The barrel pipe opening 71 on the base 7 is directly connected to the water outlet of the shaft structure 1 and is used to receive rainwater that has undergone preliminary filtration and infiltration. The base 7 is provided with at least one drainage pipe opening 72, which is used to guide rainwater from the base 7 to the municipal drainage pipe. The communication between the barrel pipe opening 71 and the drainage pipe opening 72 ensures smooth water flow and reduces the risk of water accumulation and blockage. The base 7 provides a stable support for the shaft structure 1, preventing deformation or damage to the shaft structure 1 due to soil movement or heavy pressure.

[0046] The technical solution of the present application is to set a first filter structure 2 at the water inlet end of the well structure 1, so that rainwater can pass through the first filter structure 2 to initially remove larger debris and garbage, preventing them from entering the interior of the well structure 1, thereby reducing the risk of blockage inside the drainage component; secondly, the second filter structure 3 is arranged in the well structure 1, and the second filter structure 3 is provided with a plurality of sewage interception holes, so that rainwater can pass through the sewage interception holes smoothly, and smaller debris and pollutants can be further intercepted and collected by the second filter structure 3 to prevent them from entering the municipal drainage pipe; at the same time, the second filter structure 3 is easy to take out and perform regular cleaning and maintenance to maintain the drainage smoothness of the drainage component; in addition, a plurality of penetration holes 11 are provided on the side wall of the well structure 1, and the penetration holes 11 pass through the side wall of the well structure 1, so that rainwater can penetrate into the ground smoothly through the penetration holes 11, which can not only reduce the amount of water accumulation inside the well structure 1, but also promote the natural infiltration of rainwater and the replenishment of groundwater, thereby improving the discharge capacity of the drainage component.
