Construction of Cofferdam for Steel Pipe Pile Coupling of Ningbo Bridge Liu Wanwei Ningbo Bridge is adjacent to the mouth of Minjiang River. The total length of the main bridge is 568m. It is designed as a single-tower sector double-cable prestressed concrete cable-stayed bridge with a main span of 258m. The main tower pier design is 40m×20m×5.5m. As the pier is under complex geological conditions, through the comparison and optimization of the plan, the use of a key type steel pipe pile cofferdam was finally adopted.
