You would see the heave rain in ten minutes last night if you live in Changsha. And I think the scene would shock you once you see the heavy water in the street. Of course, workers had make it done with the help of scaffolding prop.
Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man made structures. It would be very helpful for the heavy rain last night. With the higher scaffolding system’s help, we can drainage the heavy water quickly and give the convenience for passengers.
