Hidden-Manhole cover
Hidden-Manhole cover

Manhole cover-was always a hidden killer during the pipes repairs. It became a trap when it reversed. A lot of people get injury from it.
Hidden-Manhole cover is a simple design. When the workers reverse the Manhole cover, they could pull out the folded warning pipes and get people and cars attractions. This design will be able to help both pedestrian and car passed by avoid the trap and dangers. The covers also have reflective fabric which could also warning person during night time. The design could show our care on social responsibilities.
