Warning well lid / Public facilities

Warning well lid

In our daily life, necessary conspicuous warning is often lacking when the drainage system is under repairation, which brings potential safety danger to the traffic. This design combines the function of a roadblock with that of a well lid. The expansible roadblock pole can be pulled up as a warning and give people clear indication of obstacle ahead when the drainage system is under temporary repairation. Besides, a cascade of all-linked-together pattern in the center increases the leakage gaps of the well lid, thus providing a larger space for draining.
