On November 5, the completion of the hoisting of the last tuyere unit of the steel-concrete combined section of the Yongjiang Left Line Super-Large Bridge on the Newly-built North Ring Road in Ningbo Railway Hub completed the hoisting of the modular unit of the first steel cable-stayed bridge construction in China Manufacturing technology has been a success. The bridge design uses a new type of steel-concrete combination of structural connection, combined with the use of stepped-filled concrete before and after the pressure plate steel-concrete joints, through the combination of steel box girder roof, floor, web and partitions and end bearing Compression between the platen composed of steel grid room, and in which the filling of concrete, and concrete box girder
