Disclosed is a method of pasting a carbon fiber sheet on an inner wall of a large-diameter pipeline. The first tier of the carbon fiber sheet is pasted by a carbon fiber cloth (2), and the pasting of the carbon fiber cloth (2) comprises the steps of rubbing down an inner wall of a pipeline (1), keeping the surface of the inner wall of the pipeline (1) clean and arid, smearing uniformly a subbing glue on the inner wall of the pipeline (1), and using hands to gently press and paste the carbon fiber cloth (2) on a pasting area after the surface of the subbing glue is dry to touch or the surface of a leveling glue is dry to touch, installing a support device, dismantling the support device, adopting an angle grinder to grind carbon fiber cohesive glue which is squeezed out by the carbon fiber cloth (2), thus guaranteeing levelness of an entire structure plane. The method of pasting the carbon fiber sheet on the inner wall of the large-diameter pipeline realizes reinforcing of the inner wall of the large-diameter
