PURPOSE: A method for measuring a shaft alignment line at a site where a rotor is not equipped is provided to measure a shaft alignment line by verifying errors after measuring a height of a target or a staff with a measuring device and correcting a measurement value, thereby obtaining a shaft line in the state a rotor is not existed and frequently correcting a position of a pedestal. CONSTITUTION: A method for measuring a shaft alignment line at a site where a rotor is not equipped is as follows. A measurement point is set in the lowest part of an oil deflector fit being installed in a pedestal(S1). The pedestal is installed in the set measurement point(S2). A target is installed in the set measurement point(S3). An absolute horizontal line in which a measuring device reads is set(S4). A height of the pedestal is measured by using the measuring device. A height of the target is measured by using the measuring device. A correction value is obtained by verifying measurement errors. The measurement value is corrected with the correction value. |
