[0023] Reference Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a riverside sewage collection system, which includes a support component 100, a collection pipe 200, and a plurality of first drainage pipes 300.
[0024] The support component 100 is erected along the side wall of the river; the collection pipe 200 is laid on the support component 100, one end of the collection pipe 200 is sealed, and the other end of the collection pipe 200 is used to connect to the sewage treatment facility; the first drainage pipe 300 is used to discharge domestic sewage from residents, and multiple first drainage pipes 300 are connected to the collection pipe 200.
[0025] The support assembly 100 is erected on the side wall of the river channel, and the collection pipe 200 is laid on the support assembly 100. This allows the collection pipe 200 to be positioned above the river's surface, eliminating the need for river excavation, saving construction time, and reducing the risk of backflow. The primary drainage pipe 300, used for discharging domestic sewage, is connected to the collection pipe 200, centrally discharging all domestic sewage from riverside residents, preventing river pollution and improving environmental quality. It is important to understand that the support assembly 100 must be positioned above the highest water level of the river channel.
[0026] Furthermore, the diameter of the collection pipe 200 can be selected from DN150 to DN200. DN150 refers to a nominal diameter of 150mm. Generally, the design slope of the collection pipe 200 is 4‰, and the slope can be appropriately increased if required. It should be understood that the end of the collection pipe 200 used to connect to the sewage treatment facility is at a lower position, and the end to be sealed is at a higher position. The end of the collection pipe 200 can be sealed using a plug; the sealing method can be a removable plug or a permanent seal using welding or other methods.
[0027] It is understood that the first drain pipe 300 includes a first branch pipe and a second branch pipe. The first branch pipe is located above the collection pipe 200, and the second branch pipe is vertically arranged and connected to the collection pipe 200. A rounded transition is provided between the first branch pipe and the second branch pipe.
[0028] The first straight pipe is located above the collection pipe 200. Therefore, when domestic sewage is discharged into the collection pipe 200, it needs to pass through a vertically installed second branch pipe. On the one hand, the discharge speed of domestic sewage increases when passing through the vertical second branch pipe. On the other hand, when the water flow in the collection pipe 200 is too large and backflow occurs, it reduces the risk of water flowing back into the first branch pipe. The first and second branch pipes have a rounded transition; optionally, the angle between the first and second branch pipes is 90°. It should be understood that the vertical installation of the second branch pipe also includes the case where the second branch pipe is nearly vertical, that is, even a slight angle between the second branch pipe and the vertical should be understood as the second branch pipe being vertically installed. Therefore, the first branch pipe can also be designed with a slope, making it easier for domestic sewage to be discharged into the collection pipe 200 from the first branch pipe.
[0029] Understandably, it also includes multiple second drainage pipes 400, which are used to discharge residents' combined rainwater and sewage. All of the multiple second drainage pipes 400 are connected to the collection pipe 200.
[0030] In some residents' homes, rainwater and sewage are discharged together. During the rainy season or on rainy days, the volume of water discharged from the combined rainwater and sewage system is even greater, so a second drainage pipe 400 is required to discharge the combined rainwater and sewage into the collection pipe 200. It should be understood that the water flow to be handled by the second drainage pipe 400 is greater than that of the first drainage pipe 300, therefore the diameter of the second drainage pipe 400 must be larger than that of the first drainage pipe 300.
[0031] It is understood that the second drain pipe 400 includes a third branch pipe and an overflow pipe 410. The overflow pipe 410 is vertically arranged, with an overflow port at the top. The bottom of the overflow pipe 410 is connected to the collection pipe 200. The third branch pipe is connected to the overflow pipe 410, and the connection point between the third branch pipe and the overflow pipe 410 is located on the side wall of the overflow pipe 410.
[0032] Because the flow rate of combined sewer and stormwater in the second drainage pipe 400 is greater during the rainy season or on rainy days, the second drainage pipe 400 includes an overflow pipe 410 to reduce the pressure on the collection pipe 200. The overflow pipe 410 can directly discharge the upper layer of liquid from the large flow of combined sewer and stormwater. It should be understood that after sewage and rainwater mix, the sewage is diluted, and the upper layer of liquid is clearer than the lower layer. Therefore, discharging the upper layer of liquid directly into the river has a smaller impact on the environment, but it can greatly alleviate the pressure on the collection pipe 200 during the rainy season or on rainy days.
[0033] It should be understood that, generally, the diameter of the third branch pipe is greater than or equal to DN150. In some cases, the diameter of the third branch pipe may be less than DN150. Multiple third branch pipes with diameters less than DN150 can be connected to the same overflow pipe 410. In this case, the diameter of the overflow pipe 410 needs to be greater than the diameter of the third branch pipe.
[0034] It is understood that the overflow pipe 410 includes a straight pipe 411 and a bend 412. The straight pipe 411 is set vertically and is connected to the collection pipe 200. The bend 412 is connected to the upper end of the straight pipe 411, and the outlet of the bend 412 is set downward.
[0035] The length of the straight pipe 411 primarily serves to set the overflow elevation. Preferably, the length of the straight pipe 411 is not less than 10cm, meaning the overflow elevation is not less than 10cm. This is to reduce the risk of sewage backflow from the bend pipe 412. It should be understood that the outlet of the bend pipe 412 is oriented downwards to prevent external rainwater from entering the straight pipe 411 and reaching the collection pipe 200, thus reducing the impact of external rainwater on the collection pipe 200's processing capacity.
[0036] It is understandable that the collection pipe 200 is provided with multiple openable cleaning ports 210, which are located on the side wall of the collection pipe 200 and at the top of the collection pipe 200.
[0037] Domestic sewage also contains suspended solids, which tend to settle easily where the water flow velocity changes, such as at the connection between the first drain pipe 300 and the collection pipe 200, or at the connection between the second drain pipe 400 and the collection pipe 200. Over time, the accumulated suspended solids can easily clog the collection pipe 200. Therefore, it is preferable to have multiple cleaning ports 210 on the collection pipe 200, covering its entire length. During maintenance, the nearest cleaning port 210 can be opened at any potential blockage location to clean the collection pipe 200.
[0038] It is understandable that multiple cleaning ports 210 are spaced apart along the length of the collection pipe 200, and the distance between two adjacent cleaning ports 210 is less than or equal to 20m.
[0039] To facilitate cleaning of the collection pipe 200, the spacing between the cleaning ports 210 should not be too large; a spacing of 20m or less is preferable. If the spacing between the cleaning ports 210 is too large, the pipe section between two adjacent cleaning ports 210 will be difficult to clean, making it difficult to find suitable cleaning equipment or devices. Preferably, the diameter of the cleaning port 210 is set to 100mm.
[0040] Reference Figure 3 As shown, it can be understood that the support assembly 100 includes multiple supports 110, which are evenly spaced along the river channel. The supports 110 are connected end to end by multiple connecting rods to form a triangular structure. Preferably, the upper end of the supports 110 is horizontal to support the placement of the collection pipe 200.
[0041] It is understood that the system also includes a manhole 500, and the collection pipe 200 is connected to the manhole 500. Preferably, the manhole 500 is located between the collection pipe 200 and the sewage treatment facility. Solid or suspended matter in the collection pipe 200 can settle after entering the manhole 500, reducing the risk of solid matter clogging subsequent pipe sections and facilitating the long-distance transportation of sewage to the sewage treatment facility.
[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
