The invention discloses a can-shaped navigation mark. The can-shaped navigation mark comprises a plurality of arc-shaped units connected with one another in a clamped and sleeved mode. The arc-shaped units comprise upper arc-shaped frameworks, lower arc-shaped frameworks and vertical indicatrix plates arranged between the upper arc-shaped frameworks and the lower arc-shaped frameworks in a clamped and sleeved mode. The upper arc-shaped frameworks can form an upper annular framework, and the lower arc-shaped frameworks can form a lower annular framework. The can-shaped navigation mark further comprises vertical supporting rods. The vertical supporting rods are fixedly connected with the upper arc-shaped frameworks and the lower arc-shaped frameworks through fasteners. By arranging the vertical supporting rods, the position relation between the upper arc-shaped frameworks and the lower arc-shaped frameworks is fixed, the problem that the assembly order in the prior art is unclear can be solved, and the primary-secondary relation of installation of the can-shaped navigation mark can be determined. When the can-shaped navigation mark is assembled, the distance between the upper arc-shaped frameworks and the lower arc-shaped frameworks is fixed through the vertical supporting rods, so that a basic installation framework is formed, and then the vertical indicatrix plates are arranged between the upper arc-shaped frameworks and the lower arc-shaped frameworks in the clamped and sleeved mode on the basis of the framework, so that assembly is completed.
