The warning manhole cover can provide people with the position of the manhole cover, so that people can avoid being close to the manhole cover, thus endangering their lives. A circle of gap U-shaped space is designed in its inner side, and a hollow cylindrical plastic anti-collision barrel is placed in its inner side. In case of flood, just open the manhole cover, and the plastic can float upwards by water pressure by the U-shaped pipe principle. The folding anti-collision bucket can be stretched out by opening the cover of the manhole cover. This design warns people in the flood-stricken areas that they may accidentally walk to the manho.
