Niutian Yangte Bridge is a key project, difficult project and control project of Niutianyang Expressway. Both the landmark significance and the difficulty of new technology are far beyond the Big Brother Bay Bridge and the Brick Stone Bridge.
Overview chart (from Baidu Encyclopedia)
Niutian Yangte Bridge is the largest double-tower double-cable-lined bridge with double cable-stayed steel trusses across the Rongjiang River in Shantou. The upper level is an eight-lane first-class highway, and the lower level is a double-lane straddle rail transit. The main bridge is about 955.2 meters long, and the main pier tower is 182.9 meters high, which adopts the shape of The Horn Head and the Xianglu Of the Chaoshan Local Characteristics, which has quite local cultural characteristics.
The high-speed outer ring is gradually taking shape
Niutian Yangte Bridge is located at the confluence of the four rivers of Rongjiang, Hanjiang, Lianjiang and Haojiang, with rapid and changeable water flow and poor hydrological conditions. It is also in the Rongjiang Fault Zone, an octave earthquake zone, and the geological conditions are complex. Because the area is anchorage, the navigation safety requirements are high, and the navigation level is considered by the navigation standard of 10,000 tons of sea vessels. In addition, the project also adopts the public rail co-construction model, which is difficult to connect and has high landscape requirements.
According to preliminary calculations, the seismic dampers of Niutian Yangte Bridge have reached a scale of 400 tons per person, which is the largest and highest seismic cable-stayed bridge among domestic bridges. After the completion of the Niutianyang Bridge, it will provide more innovative technological achievements for the bridges in the domestic coastal high-strength seismic zone in terms of wind resistance and earthquake resistance, which has great and far-reaching significance in the field of bridge construction.
The use of hydraulic self-climbing die technology in the main tower of niutian Yangte Bridge
Up to now, the whole line of the project has entered the construction stage of the superstructure. The main tower of the bridge also methodically advanced the construction speed. The South Bank has currently completed 16 sections and the North Tower has completed 22 sections, which are expected to be capped in the first quarter of 2022.
