The invention discloses a bridge deck openable swing type inclined tied arch bridge. The bridge deck openable swing type inclined tied arch bridge comprises a curved steel main beam, an inclined steelpipe arch rib, tied arch suspenders, tied arch rotating hinges, tied arch rotating shafts, tied arch piers, an intelligent water pump device and a water pump device water pipe. The bridge deck openable swing type inclined tied arch bridge meets the special implementation scheme of the navigation clearance limit requirement, the inclined steel pipe arch rib and the curved steel main beam are connected through the multiple tied arch suspenders, the inclined steel pipe arch rib is connected with the two ends of the curved steel main beam, and the tied arch rotating hinges and the tied arch rotating shafts are arranged below the inclined steel pipe arch rib and the curved steel main beam; and the intelligent water pump device arranged in the tied arch piers pumps river water into the inclinedsteel pipe arch rib step by step, along with rising of the water level of injected water, after the gravity center of the inclined steel pipe arch rib moves to the critical value, the tied arch bridge integrally achieves automatic rotation, and therefore opening of a bridge deck is achieved.
