Description

Technical Field

[0001] This utility model relates to the field of drainage engineering technology, and in particular to a municipal rainwater flow distribution well. Background Technology

[0002] Urban flooding often occurs in old urban areas and older districts. Due to limitations such as transportation, housing, and existing pipelines, large-scale demolition and construction are not feasible in these areas. In order to make full use of existing rainwater facilities and ensure the proper drainage of upgraded rainwater, it is often necessary to accurately allocate the flow of rainwater from upstream areas.

[0003] How to control the direction of rainwater flow, and how to schedule the discharge of rainwater and accurately allocate the flow rate are urgent problems to be solved. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a municipal stormwater flow distribution well, which can control the direction of stormwater flow and realize the scheduling of stormwater discharge and accurate distribution of flow.

[0005] A municipal stormwater flow distribution well according to an embodiment of the present invention includes a well body, a municipal stormwater pipe, a first drainage pipe, a second drainage pipe, and a diversion channel. The municipal stormwater pipe is connected to the well body. The first drainage pipe and the municipal stormwater pipe are connected to the well body. The first drainage pipe and the municipal stormwater pipe are connected through the diversion channel. The second drainage pipe and the municipal stormwater pipe are connected through the diversion channel. A partition wall is provided between the first drainage pipe and the second drainage pipe.

After entering the well through the municipal stormwater pipe, rainwater flows through the diversion channel into the first and second drainage pipes. When the stormwater pipe network to which the first drainage pipe belongs is overloaded, sealing the first drainage pipe allows all rainwater to be discharged through the second drainage pipe.

[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 utility model.

[0019] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Reference Figures 1 to 3 A municipal stormwater flow distribution well includes a well body 10, a municipal stormwater pipe 20, a first drainage pipe 30, a second drainage pipe 40, and a diversion channel 50. The municipal stormwater pipe 20 is connected to the well body 10. The first drainage pipe 30 and the second drainage pipe 40 are connected to the well body 10. The first drainage pipe 30 and the municipal stormwater pipe 20 are connected through the diversion channel 50. The second drainage pipe 40 and the municipal stormwater pipe 20 are connected through the diversion channel 50. A partition wall 60 is provided between the first drainage pipe 30 and the second drainage pipe 40.

[0022] It should be noted that the first drainage pipe 30 and the second drainage pipe 40 are connected to different rainwater systems. The first drainage pipe 30 is connected to a rainwater system with limited drainage capacity, while the second drainage pipe 40 is connected to a rainwater system with sufficient drainage capacity. After rainwater enters the manhole 10 through the municipal rainwater pipe 20, it flows through the diversion channel 50 into the first drainage pipe 30 and the second drainage pipe 40. When the rainwater pipe network to which the first drainage pipe 30 belongs is overloaded, blocking the first drainage pipe 30 will allow all rainwater to be discharged through the second drainage pipe 40.

[0023] It should be noted that the first drain pipe 30 and the second drain pipe 40 are connected to different downstream drains.

[0024] Reference Figures 1 to 3 A first water-blocking gate 31 is movably inserted into the first drainage pipe 30.

[0025] Reference Figures 1 to 3 A second water-blocking gate 41 is movably inserted into the second drainage pipe 40.

[0026] It is understandable that the first drain pipe 30 can be blocked by the first water gate 31. When the rainwater pipe to which the first drain pipe 30 belongs is overloaded, blocking the first drain pipe 30 will allow all rainwater to be discharged through the second drain pipe 40.

[0027] Conversely, the second water-blocking gate 41 can block the second drainage pipe 40. When the rainwater pipe to which the second drainage pipe 40 belongs is overloaded, blocking the second drainage pipe 40 will allow all rainwater to be discharged through the first drainage pipe 30.

[0028] Reference Figure 3 The top slope of the guide channel 50 is not less than 5%.

[0029] It should be noted that the top of the guide channel 50 has a slope. In the embodiment of this utility model, the slope of the top of the guide channel 50 is not less than 5%, so as to realize the diversion of water above.

[0030] Reference Figures 1 to 3 The upper end of the diversion channel 50 is flush with the upper end of the municipal rainwater pipe 20.

[0031] Understandably, the height of the diversion channel 50 is flush with the upper end of the municipal rainwater pipe 20. The two are sized to match, so there will be no impact or eddy currents, thus achieving smooth diversion.

[0032] Reference Figures 1 to 3 The height of the partition wall 60 is equal to the height of the well body 10.

[0033] Understandably, the partition wall 60 is at the same height as the well body 10, which can separate all rainwater and prevent water from flowing together above the partition wall 60.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
