The invention discloses a bidirectional-swinging pier hinge which comprises a rectangular hollow core tube, overall hanging sleeves and an externally connected protection sleeve. The overall hanging sleeves are composed of a rigid rotating shaft, two rigid supports, two rigid supporting plates, four rigid baffles, two hinge shafts and a rectangular hollow outer sleeve. The rectangular hollow outer sleeve is welded to the rigid supporting plates and installed in semicircular grooves reserved in the two ends of the rectangular hollow core tube through the rigid rotating shaft and the rigid supports. The externally connected protection sleeve is made of a low-yield-point steel sheet and is welded to the upper overall hanging sleeve and the lower overall hanging sleeve. The bidirectional-swinging pier hinge is clear in concept and principle, easy to produce, convenient to maintain and capable of being installed in an area where a plastic hinge is likely to generate and relieving the damage of a bridge structure under the earthquake action.
