Fixed-point revolving follow-up method for round structure

The invention discloses a fixed-point revolving follow-up method for a round structure. The method comprises the following mounting steps of 1.1, hoisting a 100t automobile in a hall top, mounting a center ring and a center ring supporting truss on an assembling bed-jig in the middle of the hall top and constructing an assembling platform; 1.2, mounting a hydraulic crawler and other sliding equipment on the lower side of the assembling platform and debugging a power system; 1.3, mounting a sliding temporary structure on the hall top, and splicing a first sliding unit on the assembling bed-jigby means of an assembling platform; and 1.4, rotating the first sliding unit at a sliding degree clockwise, and assembling a second sliding unit. According to the fixed-point revolving follow-up method for the round structure, the hall top is constructed by means of a method of fixed-point mounting and symmetrical revolving accumulated sliding construction. Two 400 t crawler cranes are input on site for mounting a steel s
