Abstract
PURPOSE: To work a flange surface of an outer casing in parallel with that of an inner casing by a method wherein a specified size is kept from measuring central lines of an optical measuring device, which are oriented in parallel with the inner casing flange surface.
CONSTITUTION: An inner casing 2 and an outer casing 3 of a tubular water wheel are installed at an installation site by concrete etc. An optical measuring device 13 provided at outside of the outer casing 3 is oriented in such a way as a moving locus of a measuring central view line 14 is spaced apart with a distance 15 from a flange surface 12 of the inner casing 2. A distance 16 is kept by a scale with respect to the measuring central view line 14 and a flange surface 9 of the outer casing 3 is ground by a grinder, and the flange surface 9 may be worked in parallel with the flange surface 12 of the inner casing.
