Rainwater outlet:
The gap between the two sides of the road to discharge rainwater leads directly to the sewer, which is covered with iron fences.
Refers to the facilities for collecting surface water in the pipeline drainage system, which are composed of intake grille, shaft and branch pipes, and are divided into eccentric ditch type, flat plate type and combined type.
Rainwater well:
In fact, it is the manhole of the rainwater pipe, which is a well-shaped structure made of glue or brick to facilitate regular inspection, cleaning and dredging or inspection of underground operations.
There are holes on the side connected with the drainage pipeline, and there is a seepage pipe extending downward at the bottom, which can replenish rainwater to the ground and discharge excess rainwater through the drainage pipeline to slow down the ground settlement and prevent the road surface from being flooded during the rainstorm. There are baskets in the well, which can intercept dirt, prevent the drainage pipes from being blocked and facilitate cleaning.
Difference:
Different uses.
The rainwater outlet is used to collect ground rainwater and is connected to the rainwater well through the water collection branch pipe.
Rainwater well is set on the main rainwater pipe to collect rainwater collected by rainwater outlet and clean it for daily maintenance.
