Precision control method for moving and folding giant block

The embodiment of the invention provides a giant block moving and folding precision control method. Module cars and rail cars are adopted for moving and folding the giant block, or the rail cars are independently used as moving equipment. Before closure, a final closure site, namely a closure positioning block, is determined according to a production line table. And the center line of the positioning block is used as a monitoring reference in the moving process when the closure block is constructed. Due to the fact that the rail car is adopted in the transferring device, the distance between the rail where the rail car is located and the center line of the positioning block is reserved. And in the folding process, it is ensured that the center lines of the folding block and the positioning block are kept consistent after folding. Before the folding block and the positioning block are completely folded and butted, the folding end faces are pre-cut by collecting the precision data of the folding end faces of th
