Rainwater bucket belongs to the branch of metal falling water system, which is located at the entrance of rainwater from roof gutter into rainwater pipeline.
The rainwater outlet is a structure that collects rainwater on the rainwater pipe canal or the confluence pipe canal. The rainwater on the street surface first flows into the drainage pipe through the rainwater inlet and the connecting pipe.
2. Different roles
The rain bucket is equipped with a rectifying grid device, which can quickly drain the rain from the roof. The grille has the function of rectifying, avoiding the formation of too many whirlpools, stabilizing the water level in front of the hopper, reducing aeration, quickly removing rainwater and snow water on the roof, and effectively blocking larger sundries.
The form, quantity and layout of the rain outlets should be determined according to the water quantity generated by the catchment area, the discharge capacity of the rain outlets and the road form. The position of the rain outlet should ensure that the surface rainwater can be collected quickly and effectively.
3. Different functions
Rainwater outlet shaft can be prefabricated by brick or reinforced concrete, and can also be made of top concrete pipe. Pollutant interception facilities should be set up at the rain mouth to reduce the insoluble pollutants generated by surface runoff from entering the receiving water body. In order to avoid odor overflow from sewage, measures such as setting water seal or adding chemicals should be taken to prevent odor overflow from rainwater outlet of combined system.
