Safe Well Cover / Manhole cover

Safe Well Cover
Safe Well Cover

In southern China, when a short-term heavy rainfall occurs in a city, sometimes the ash will rain and the manhole cover will be washed away, causing irreparable damage.
In this design, the original structure of the manhole cover is improved, and the manhole cover is designed as a lifting and unfolding type.
When solving the structural problem of how the manhole cover is unfolded, the expanded part is added to the warning function device to remind passing vehicles and pedestrians.
