The invention discloses a splicing structure used for a combined type tunnel lining, a culvert or a comprehensive pipe gallery. Unit plates are spliced into pipe joints in a circumferential direction; the pipe joints are axially spliced to form the tunnel lining, the culvert or the comprehensive pipe gallery, wherein when the pipe joints are axially spliced, contact end parts of adjacent unit plates are provided with folding sides folded to the outer sides of the pipe joints or hollow cavity structures with cross sections peripherally closed; and the contact surfaces of the adjacent folding sides or the hollow cavity structures are spliced connecting surfaces. The splicing structure is not exposed to the inner part of the tunnel or the culvert, does not affect passing vehicles therein and avoids collision or scratches; and meanwhile, the spliced part of the tunnel or the culvert inner wall is smooth and attractive, the inner passing space is increased, the section area is reduced, the engineering excavated volume is reduced, and the construction period is shortened.
