Abstract

PURPOSE:To prevent noise from being caused when existing concrete is broken by connecting a nozzle device for new construction to an existing nozzle device and newly overlapping the pavement material for road surface on the old road surface only at the amount which has been made higher by this connection and forming the new road surface. CONSTITUTION:The central part of the top wall 61 of a nozzle main body in an existing snow removing nozzle mouth is cut into a circle by an end mill 52. Both the surrounded part 64 and the built-in material 65 such as an old valve are removed by this circular cutting. A boring stage and a tapping six- cutting stage which are fitted with a nozzle device (a) for new constraction applied in the space formed by this removal are performed by utilizing a drill 53, a tap 54 and the end mill 55. The nozzle device (a) for new construction is introduced into the obtained space 71 in a fitting state by utilization of a tapping hole 68 and a welding means 24. In such a way, the new pavement material for road surface such as concrete and asphalt is overlapped on the existing road surface 73 to form the new road surface 74. As a result, noise and vibration are not caused when the existing concrete is broken.
