Abstract

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.

Description

technical field [0001] The invention relates to the technical field of bridge engineering in the transportation infrastructure industry, in particular to a pendulum-type inclined tie-bar arch bridge with an openable bridge deck. Background technique [0002] With the continuous and rapid development of China's economy, the process of urbanization and industrialization has been accelerating, and the transportation infrastructure industry has developed rapidly. A large number of municipal roads, highways, railways and rivers have formed spatial intersections. Considering that the navigation conditions of rivers need to be reserved for the development of the next few decades, the requirements for the navigation limit are often high. Combined with the dense urban environment and the existing complicated site conditions, if the elevation of the whole line is raised or the elevation of the roadbed is raised to meet the requirements of the river navigation limit at a specific locati...
