There are provided a method for removing a blade ring by pulling out the blade ring smoothly and surely while preventing damage to other components, and a member for removing a blade ring. By using a dummy blade ring, connection plates, and connecting bolts, work for removing and mounting a lower half section of the blade ring is performed. Thereby, work of rotation and the like can be performed while the lower half section of the blade ring and the dummy blade ring are connected to each other in both end portions. Therefore, during the work, the lower half section of the blade ring and the dummy blade ring are prevented from shifting from each other and therefore from interfering with the opposed rotor blade tip, a lower half section of a casing, and the like, thus preventing damage to the tip, distortion of the lower half section of the blade ring and the dummy blade ring, and the like. Consequently, a stator blade ring can be pulled out smoothly and surely.
