The invention discloses a manufacturing method of a correction device. The manufacturing method comprises the following steps that a simulated assembly drawing of the correction device is drawn according to a drawing of an expansion joint; an assembly part drawing and an auxiliary part drawing are drawn according to the simulated assembly drawing, wherein the assembly part drawing is the drawing of parts for forming the correction device, and the auxiliary part drawing is the drawing of temporary parts used when the correction device is assembled; according to the assembly part drawing and theauxiliary part drawing, assembly parts and auxiliary parts are manufactured respectively; and the correction device is assembled according to the simulated assembly drawing. The invention further discloses the correction device manufactured by the manufacturing method and a using method of the correction device. By means of the correction device, rainwater can be prevented from entering a dieselengine, a smoke exhaust pipe can be conveniently corrected, and the expansion joint can be prevented from being damaged.
