The utility model relates to the technical field of tunnel construction, in particular to an accurate punching device for duct pieces in a tunnel, a magnetic element is embedded in the center of a punching cabinet, positioning through holes are formed in the four corners of the punching cabinet, and a horizontal bubble instrument is arranged at the top of the punching cabinet. The punching cabinet of a special structure is designed according to the reinforcement cage structure of the duct piece in the tunnel, the magnetic element is used for detecting, positioning and determining the position of the reinforcement of the duct piece, the positioning through holes are distributed around the positioning through holes and used for punching, the reinforcement cage structure of the duct piece in the tunnel is effectively avoided, punching is efficient and accurate, and construction efficiency is improved. The horizontal bubble instrument can detect the horizontal position in real time to ensure that the horizontal h
