The invention discloses a dynamic visual device for a cast-in-place pile underreaming drill bit, and relates to the technical field of cast-in-place devices. The device comprises a cab module, a drilling machine power head module, an underground module and a winch module; the cab module and the underground module are both connected with the drilling machine power head module, and the winch module is connected with the cab module. The cab module is arranged in a drilling machine cab; the underground module is used for collecting angle data and displacement data; the angle data is the opening angle of a wing plate of the underreaming drill bit, and the displacement data is the displacement of an oil cylinder of the underreaming drill bit; the winch module is used for collecting speed displacement data; the speed displacement data comprises lowering speed and lowering length of a steel wire rope of the winch; the cab module is used for determining and displaying attitude information of the underreaming drill bit
