The invention provides a verticality measuring device and method for a vertical cylindrical structure in a construction process. The measuring device comprises an assembled positioning ring and a perpendicularity measuring mechanism mounted on the positioning ring, the perpendicularity measuring mechanism comprises a vertical mounting plate, a measuring cross rod, a target bottom plate and a laser pendulum bob, the target bottom plate is perpendicular to the vertical mounting plate, a target is arranged on the target bottom plate, and the laser pendulum bob is arranged on the measuring cross rod. And the laser pendulum bob is suspended above the center of the target through the measuring cross rod. During measurement, a component to be measured is fixed through the positioning ring, the perpendicularity measuring mechanism is adjusted through the right-angle ruler to enable the target bottom plate and the measuring cross rod to keep relatively parallel, and reading and recording of perpendicularity deviation
