As a result, the support base plate 3 is fixedly installed on the chimney 1 horizontally. At this time, the second legs 8.8a, 8b...
Leave it in a free state without fixing it by 0. Therefore, the crushing blade 20 of the crushing section 18 is extended by hydraulic drive, and together with the fixed blade 21, a concentrated load is applied to the chimney wall portion 1a between these blade edges to crush the chimney wall 1a. The position of the crushing part 18 is moved by operating the rotary drive body 2. This crushing and positional movement are repeated alternately, and when the entire circumference of the upper opening of the chimney 1 has been crushed, the crushing part 18 is moved. Stop crushing. Then, the drills 10, which are the fixed parts of the second legs 8, 8a, 8b, are extended, and their tips are bitten into the chimney wall 1a, thereby fixing these legs. Thereafter, the fixing portions 9 of the first legs 7, 7a... are released. and the second leg 8.8a.
