Embodiment 1

[0045] An initial rainwater flow device in a new urban area, comprising: drainage groove 1, rainwater grate hole 2, sewage collection tank 3, rainwater pipe 4, and water crossing threshold 5.

[0046] The above-mentioned drainage groove 1 is a rectangular parallelepiped, with a width of not less than 100cm, a length of not less than 150cm, and a depth of not less than 30cm, and is buried on both sides of the road in a sinking manner; the upper part of the drainage groove 1 is provided with rainwater grate holes 2 through which rainwater passes. The grate hole 2 enters the drainage groove 1.

[0047] The diameter of the rainwater pipe 4 mentioned above is the general diameter of the municipal pipe network. The rainwater pipe 4 is directly connected to the drainage channel 1. The water in the drainage channel 1 can directly enter the rainwater pipe 4. A circle of water crossing threshold with a diameter slightly larger than that of the rainwater pipe 4 is arranged around the rainwater...

Embodiment 2

[0069] The other content is the same as the first embodiment, except that the sewage collection tank is 1m 3 Cube structure, the box includes: empty piston 35, cavity 36, oblique drain hole 37, spring 38, spring bracket 39;

[0070] The spring 38 is fixedly connected to the hollow piston 35 and the spring bracket 39, the spring 38 is arranged above the hollow piston 35 and below the spring bracket 39, and the spring bracket 39 is fixed on the sewage collection tank 3; the inclined drainage hole 37 is provided at the inlet At the bottom of the sewage collection tank 3, the outlet is set on the upper part of the wall of the sewage pipe 6 and communicates with the sewage pipe 6 with a hole diameter of 5 cm; the Hooke coefficient k of the spring 38 is 300 N / m;

[0071] The hollow piston 35 is two cylinders with different diameters connected to each other. The diameter of the upper cylinder is slightly larger than the inner diameter of the sewage pipe 6 and the height is 5 cm. The diamet...

Embodiment 3

[0079] The other contents are the same as the first embodiment, except that the sewage collection tank 3 has a rectangular parallelepiped structure of 1.5m×1.5m×0.5m. The box includes: a water receiver 311, a connecting rod 312, a lightweight piston 313, a support spring 314, and a support spring Bracket 315;

[0080] The bottom of the water receiver 311 is connected to the lightweight piston 313 through a connecting rod 312, a support spring 314 is connected under the water receiver 311, and the lower part of the support spring 314 is connected to a support spring bracket 315, and the support spring bracket 315 is fixed to the sewage collection tank 3 On the inner wall of the inlet; the Hooke coefficient of the supporting spring 314 is 700N / m.

[0081] The water holder 311 is a cylindrical open container with a bottom diameter of 30 cm and a height of 10 cm; the bottom surface of the water holder 311 is higher than the top of the water sill 5 by 10 cm; the water holder 311 has a d...

Abstract

The invention relates to a new urban district initial rainwater flow dividing device and arrangement thereof, and belongs to the field of urban water conservancy facilities. The device comprises a draining groove, rainwater grate holes, a sewage collection box, a rainwater pipe and a water passing sill. According to the arrangement, a main arterial traffic in new urban district oval planning serves as an area boundary to be subjected to space division, a rainwater area with the planed arterial traffic as the boundary is obtained, and the rainwater flow dividing device is arranged in the rainwater area. The device has the following beneficial effects that the rainwater in the new urban district at different time periods is classified and drained into an urban rain sewage pipe network, and the river flow pollution is reduced. A mechanical device is completely adopted, a sensor and a controller are not needed, cost is low, reliability is high, and the device is suitable for being widely used.

Description

Technical field [0001] The invention relates to a device for initial rainwater flow in a new urban area and its arrangement, in particular to a device for classified discharge of rainwater into an urban rain and sewage pipe network at different times in a new urban area and an arrangement method thereof, belonging to the field of urban water conservancy facilities. Background technique [0002] It can be known from the existing research that the rainwater before the initial rainfall of 10mm in the city is sewage containing a certain amount of ground dust, rubber rubber particles, and oil. It should be discharged into the sewage pipeline and purified. Rainwater that falls after the urban ground has been washed clean and the rainfall reaches 10mm can be discharged as natural rainwater into rainwater pipes and flow into the river. However, the prior art does not yet have an initial rainwater separation device to separate the initial rainfall in the city. The existing rainwater sinks...
