[0002] Storm inlets are an important component of urban drainage systems. They are typically located at road intersections, the lowest points of roads, and along curbs to collect rainwater from the road surface and discharge it into storm drains.

[0003] However, when rainfall is heavy, the existing storm drains cannot keep up with the flow, and roads are prone to flooding. In addition, rainwater often contains debris such as tree branches, which can clog the storm drains, making it difficult for rainwater to enter and exacerbating the flooding. Utility Model Content

[0027] Reference Figure 1 The embodiments of this application provide a multi-stage sedimentation overflow rainwater inlet system.

[0028] The rainwater well 1 has at least a first inlet 11 and a second inlet 12 on its side wall from bottom to top; the rainwater well 1 also has a first outlet 13 on its side wall.

[0029] Sediment infiltration well 2 is connected to the inner wall of rainwater well 1; the side wall of sediment infiltration well 2 is provided with at least a third inlet 21 and a fourth inlet 22 from bottom to top; the first inlet 11 is provided corresponding to the third inlet 21, and the second inlet 12 is provided corresponding to the fourth inlet 22; the side wall of sediment infiltration well 2 is provided with a second outlet 23; the first outlet 13 is provided corresponding to the second outlet 23;

[0030] The sedimentation tank 3 is located on the outer side of the side where the first inlet 11 of the rainwater well 1 is located.

[0031] The rainwater well 1 is used to temporarily store rainwater that cannot be drained away in time during heavy rainstorms. Optionally, the rainwater well 1 can be a cylindrical or square structure with an open top.

[0032] Overflow inlets of different heights are installed on the sidewall of the rainwater well 1, including at least a first inlet 11 and a second inlet 12. Different inlet heights correspond to different regulating water levels. For example, the height of the first inlet 11 corresponds to the annual runoff volume control rate control water level, the height of the second inlet 12 corresponds to the 10-year return period control water level, and the top surface of the rainwater well 1 corresponds to the 30-year return period control water level. The height of each inlet can be set based on empirical values ​​or calculated through simulation. Understandably, inlets of other heights can also be installed according to actual needs.

[0033] A sedimentation well 2 is installed on the inner wall of the rainwater well 1. This sedimentation well 2 can be pulled out of the rainwater well 1 for easy cleaning later. A third inlet 21 and a fourth inlet 22 are provided on the sedimentation well 2 at positions corresponding to the first inlet 11 and the second inlet 12 of the rainwater well 1. Similarly, when inlets of other heights are provided on the side wall of the rainwater well 1, inlets are also provided at corresponding positions on the sedimentation well 2. The sedimentation well 2 can be made of stainless steel or plastic. A through hole 24 can be provided at the bottom of the sedimentation well 2 to facilitate ventilation and make it easy to pull out after sediment deposition, preventing difficulty in removal due to silt blockage.

[0034] A first outlet 13 is provided on the side wall of the rainwater well 1, and a second outlet 23 is provided at the corresponding position in the sedimentation well 2. A water outlet pipe 6 is connected to the first outlet 13 and the second outlet 23, and the water outlet pipe 6 is connected to the municipal water supply network. Water from the rainwater well 1 is discharged into the municipal water supply network through the water outlet pipe 6. Understandably, to ensure smooth drainage of rainwater from the rainwater well 1, the first outlet 13 can be positioned opposite the first inlet 11.

[0035] A sedimentation trough 3 is provided on the outer side of the first inlet 11 of the rainwater well 1. The sedimentation trough 3 is used to collect rainwater and discharge excess rainwater into the rainwater well 1.

[0036] In one embodiment, the multi-stage sedimentation overflow storm drain system further includes a grating 4, which connects the top of the sedimentation trough 3 and the top of the storm drain 1. The grating 4 is used to prevent large pieces of debris from entering the sedimentation trough 3. The grating 4 can be hinged to the sedimentation trough, allowing it to be opened at any time for cleaning the sedimentation trough 3. It is understood that the grating 4 can also be hinged to the storm drain 1.

[0037] In one embodiment, the height of the sedimentation tank 3 is flush with the first inlet 11. Rainwater within the annual runoff volume control rate control water level line is stored in the sedimentation tank 3. When there is a moderate to heavy rainstorm, rainwater with a water level line higher than the annual runoff volume control rate control water level line is discharged into the rainwater well 1 through the first inlet 11 or even the second inlet 12 and then into the municipal pipe network.

[0038] In one embodiment, the multi-stage sediment overflow storm drain system further includes a storm drain grate 5, which covers the opening of the storm drain well 1, and the bottom edge of the storm drain grate 5 is hinged to the sediment infiltration well 2.

[0039] In one embodiment, the sedimentation tank 3 is 10-15 cm higher than the bottom of the bioretention device.

[0040] The multi-stage sediment overflow storm drain system provided in this application can be installed in medium to large-sized sunken green spaces, bioretention ponds, or regulating ponds, as well as in centralized water storage areas along municipal roads to regulate road rainwater.

[0041] In this embodiment, by opening multi-stage overflow inlets of different heights on the sidewall of the rainwater well, with different inlets corresponding to different rainwater levels, excess rainwater can be discharged into the rainwater well through the overflow inlets during heavy rainstorms, and then discharged into the municipal pipe network through the first outlet of the rainwater well, thus avoiding the phenomenon of water accumulation on roads during heavy rainfall.

[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
