In Ningbo Fuming road the bridge span across Ni-ngbo East Railway Station is a cable-stayed bridge with double cable planes of the Twin Towers 55+45+220+45+55=420m. Main beam using hybrid girder, the two sides across the prest-ressed concrete box girder, in the range of 197.2m with steel box girder, steel girder and prestressed concrete box girder intersection position is 2m long steel-concrete joint section, half floating system. The main girder span Ningbo East Rail-way Station location across the Ningbo-Taizhou-Wenzhou rai-lway line 2, and line 5; across the bus full of line 5, parking line 7; span and auxiliary station line 2 and the basic platform and the intermediate platform. In view of main girder cross lines, tower close to existing lines, the characteristics of organization and coordination are difficult, mid-span steel girder construction scheme with a push of the tower, tower construction technology with hydraulic climbing formwork.
