The invention discloses a pulling and pressing bidirectional limiting device for a structural joint of a navigation aqueduct, and relates to the technical application field of civil engineering and earthquake engineering. Each group of steel plates comprises a mounting back plate and a plurality of triangular steel plates; the tips of the triangular steel plates of the two groups of steel plates are crossed and stacked; a sliding groove is formed in the middle of each triangular steel plate. Fixing cylinders are arranged on the sides, close to the mounting back plate, of the sliding grooves, and sliding cylinders are arranged in the overlapping area of the sliding grooves of the two triangular steel plates. The device is of a steel structure and can provide enough rigidity and the limiting capacity of accurately controlling displacement; under the action of a strong earthquake, the liquid viscous damper is combined with the liquid viscous damper for use, so that the relative displacement between the groove bo
