り、コスト高になるという問題もあつた。Problems to be Solved by the Invention In this conventional method, the lining is dismantled using chiseling tools such as breakers and coal pick hammers, which generates noise of 60 to 90 phon, which may be a problem for nearby residents. There is a problem in that working hours must be regulated to prevent noise pollution, and vibration problems occur because workers directly handle vibrating tools.Furthermore, since the work is carried out on the gondola, workers do not have to work on the gondola. There was also a risk of falling from the ground, which was unfavorable from a health and safety perspective for workers. Furthermore, since the tools used are manually applied to the working section, the working efficiency is low, and combined with the above-mentioned working time restrictions, the number of working days increases, resulting in high costs.

Since the destruction of the lining part is carried out by a hydraulic device, there is no need for direct human power as in the past, so the work efficiency is high. Furthermore, since there are no restrictions on work time, construction can be completed in a short period of time, resulting in lower costs, which has great effects. In addition, the blade for destroying the lining part is composed of a cutting edge part whose plunge length is approximately equal to the thickness of the lining part, and a regulating part for regulating the thrust length of this cutting edge part. Only the lining can be destroyed without destroying the chimney barrel.
