Technical Field
[0001] The utility model relates to the field of temporary sewage and drainage at construction sites, in particular to an auxiliary device for rainwater and sewage diversion. Background Art
[0002] During the construction process, many temporary rainwater and sewage drainage projects will be generated.
[0003] In detail, all water flowing out or flushing from roads, hardened surfaces, living area floors, etc. during construction projects should be counted as sewage, because the oil stains, soil debris, dust, and dirt contained in them are much higher than those on ordinary urban surfaces. Especially in areas with strict sewage discharge management, these waters should be connected to temporary sewage systems and eventually flow into the municipal sewage system.
[0004] During the rainstorm season, the water generated by heavy rain washing temporary surfaces and roads of the project is still considered sewage in the short period before the beginning of the rainstorm. However, during the rainstorm, due to the heavy rainfall, it should be considered rainwater.
[0005] However, the temporary drainage systems on the ground and roads of general projects do not distinguish between drainage during heavy rains. During the heavy rain season, the temporary drainage systems will receive a large amount of rainwater that should have been discharged into the municipal rainwater wells. This will cause excessive rainwater to flow into the sewers and sewage treatment plants, causing system overload, resulting in urban flooding and water pollution.
[0006] It can be seen from this that during the construction process, it is particularly important to distinguish between the temporary roads during heavy rains, rainwater on the ground, and sewage. Utility Model Content

[0021] With respect to the above technical solution, preferred embodiments are now cited and specifically described in conjunction with the accompanying drawings.
[0022] Auxiliary devices for rainwater and sewage diversion, such as Figure 1 As shown, it includes a drainage pipe 1, which is made of a PVC pipe with a length of not less than 500mm and a diameter of not less than 200mm. In this embodiment, the drainage pipe 1 is a long circular groove structure, which is made by splitting the PVC pipe in half along the length direction and taking the split half of the PVC pipe. The bottom of the drainage pipe 1 faces downward and the open end faces upward, which is used to receive the water discharged from the drainage pipe above it. A hole is opened at the bottom of one end of the drainage pipe 1 and about 50mm away from the port. The hole has a diameter of about 10mm. The hole passes through a "T"-shaped steel bar 2 with a diameter of not more than 10mm. The horizontal section of the "T"-shaped steel bar 2 is located in the drainage pipe 1, and the vertical section passes through the hole of the drainage pipe 1 and is located below the drainage pipe 1, and is welded to the center position of the circular load plate 3 located below the drainage pipe 1. The load plate 3 is suspended and supported by the drainage pipe 1. The load plate 3 is provided with pancake-shaped counterweights 6 of various gravities, and a notch is provided along the radial direction from the center of the counterweight 6 toward the edge of the counterweight 6 . According to the counterweight requirements, a suitable counterweight 6 can be selected and placed on the load plate 3 .
[0023] The drainage pipe 1 has holes on opposite sides at the center, with a hole diameter of about 20 mm. The "J"-shaped steel bars 4 with a diameter of not less than 10 mm pass through the holes respectively. The middle horizontal section of the "J"-shaped steel bar 4 is not less than 20 cm and is inserted into the holes of the drainage pipe 1; the vertical section is not less than 30 cm high and is located below the drainage pipe 1. A concrete fixed support 5 is provided below the "J"-shaped steel bar 4. The vertical section of the "J"-shaped steel bar 4 is buried in the concrete fixed support 5, and the "J"-shaped steel bar 4 is supported by the concrete fixed support 5; so that the drainage pipe 1 can rotate with the horizontal section of the "J"-shaped steel bar 4 as the rotation axis. And the concrete fixed support 5 should limit the rotation angle of the drainage pipe 1 to -30° to 30°.
[0024] like Figure 2 As shown, when in use, the concrete fixed support 5 is set between the rainwater sedimentation tank 7 and the sewage sedimentation tank 8, and the end of the drainage pipe 1 without the "T"-shaped steel bar 2 is located above the rainwater sedimentation tank 7 and below the drain pipe, which is used to receive the water discharged by the drain pipe; the end of the drainage pipe 1 with the "T"-shaped steel bar 2 is located above the sewage sedimentation tank 8. When the drain pipe is discharged normally, the end of the drainage pipe 1 with the "T"-shaped steel bar 2 is inclined toward the sewage sedimentation tank 8, and the sewage is discharged normally into the sewage sedimentation tank 8. Through the amount of water received in the drainage pipe 1 and the weight of the counterweight block 6, the two ends of the drainage pipe 1 can respectively drain rainwater and sewage into the corresponding rainwater sedimentation tank 7 or sewage sedimentation tank 8 as needed.
[0025] How it works:
[0026] First, a suitable counterweight, namely, a counterweight block 6 , is placed on the load tray 3 .
[0027] During non-rainstorm periods or at the beginning of a rainstorm, sewage is discharged normally from the drain pipe 1. The amount of sewage discharged is not large and falls on the drainage pipe 1. Since the impact of the water flow is not enough to pry one end of the counterweight 6, the drainage pipe 1 as a whole tilts toward the side where the counterweight 6 is provided, that is, tilted toward the sewage sedimentation tank 8. The sewage normally flows into the sewage sedimentation tank 8 and is discharged into the municipal sewage well.
[0028] During heavy rain, a large amount of rainwater is discharged from the drainage pipe 1. Since the water speed and water volume are relatively large, the impact of the water flow pries one end of the counterweight 6, causing the drainage pipe 1 to tilt toward the other end as a whole, that is, the drainage pipe 1 tilts toward the rainwater sedimentation tank 7, and a large amount of rainwater flows into the rainwater sedimentation tank 7, realizing rainwater and sewage separation.
[0029] In addition, since the counterweight 6 is adjustable, the drainage tube 1 can be adjusted to make a tilting reaction in a suitable rainstorm by testing the weight of the counterweight 6. The overall device does not require other operations except adding or removing the counterweight 6, which is simple and convenient.
[0030] The above contents are intended to illustrate the technical means of the utility model, but not to limit the technical scope of the utility model. Those skilled in the art can make obvious improvements to the utility model in combination with existing common knowledge, which also fall within the scope of protection of the claims of the utility model.
