[0031] As shown in Fig. 2, the cutting dismantling device (170) may include a belt-shaped cutting device (171), such as a band saw or wire saw, capable of cutting the outside of a large concrete drum (10), a clamping unit (173) that tensionally clamps both ends of the cutting device (171), an up-and-down driving unit (175) that is placed on the upper portion of the large concrete drum (10) while the clamping unit (173) clamps the cutting device (171) and pneumatically drives it up and down, and a guide rail fixing moving unit (177) that can move along the guide rail (151) of the guide rail device (150).

[0032] When the exterior of a large concrete drum (10) is cut once by the above-mentioned cutting and dismantling device (170), the rotating platform (110) is moved to a predetermined angle so that the cutting and dismantling device (170) is positioned relative to the large concrete drum (10) so that the next cutting and dismantling operation can be performed.
