Safety covers

When streets are flooded, water will put the pressure on the metal device. Then the second layer will depart from the upper cover and descend to drain the water. The fixed barrier centered in the cover will prevent people from falling into the big hole. In general circumstances, springs under the cover will prop up the upper layer.
