(54) MANHOLE TWIST


(57) The idea of the Twist Manhole has its origins in the need of solving one of the problems that arise during the execution of works regarding the restoration of road surfaces. In fact, when a road is rebuilt, the finished level of the road surface matches the level of the manhole's top surface. Later, when intervention works are going to be made on the restoration works of the existing asphalt surface with the installation of an additional layer, because the height of manholes currently in the market can only be modified by carrying out construction work, it happens that the same ones are being left the same in order to avoid the need of carrying put further construction works around the manhole. The Twist Manhole has been designed to address this specific issue. In fact, with a simple twisting movement, clockwise or counterclockwise, and thanks to a four-armed tool, it is possible to increase or reduce the height of the manhole itself.
