On August 10, the world's largest span three-tower cable-stayed bridge built by China Railway Bridge Group Corporation - Chaoma Intercity Railway Ma'anshan Highway-Railway Dual-purpose Yangtze River Bridge No. 3 pier main tower concrete pouring was completed, marking the completion of the main tower. The tower began to transfer to the construction phase of the middle tower column.
The Ma'anshan Highway-Railway Dual-purpose Yangtze River Bridge is a key control project for the Chao-Ma Intercity Railway and will set a number of world records.
The main tower is constructed by a super high multi-limb steel-concrete composite tower. The middle main tower is up to 345.6m, which requires high process requirements and is difficult to control linearly.
After the bridge is completed, it will be of great significance to further improve the layout of the regional high-speed railway network, enhance the channel transportation capacity, and promote the high-quality integrated development of the Yangtze River Delta and the development strategy of the Yangtze River Economic Belt.
