Zusammenfassung:	PURPOSE:To coat a waterproof layer efficiently, by a method wherein a spraying robot composed by attaching a spraying nozzle with a dust collector to a rotatable, swingable, telecopic boom is removably mounted on a traveling car and a quickly hardenable synthetic resin is sprayed on the inner surface of a tunnel. CONSTITUTION:A spraying robot 1 to which a spraying nozzle 8 with a dust collector is attached rotatably and swingably along the inner surface of a tunnel is mounted on a traveling car 2. As the traveling car 2, a construction machine such as a backhoe may also be used. An interval between the nozzle 8 and a segment 9 is finely controlled by an optical sensor 8d. A fast-curing synthetic resin is sprayed on the inner surface of the tunnel and a waterproof layer is formed. In this way, a construction period can be shortened.
