PROBLEM TO BE SOLVED: To greatly save time for maintenance work and to make effective access to the component of a turbine by passing through a combustor casing when necessary. SOLUTION: After a tool support 37 having a proper tool is inserted into the outer casing of a turbo machine, a connecting member between the upper part 27 and the lower part 28 of an inner casing 12 is separated, then the upper part 27 of the inner casing 12 is lifted inside the outer casing until the tool support 37 makes access to the inside of the inner casing 12. For this, at least one receiving device 32 is disposed for a lifter 33 in the upper part 27 of the inner casing. At least one radial gap 36 is formed between the outer casing and the inner casing, and this radial gap 36 corresponds to at least the radial width of the tool support 37 to be inserted into the inner casing 2. |
