The main span of the Shanghai-Suzhou-Nantong Yangtze River Rail-cum-Road Bridge is 1 092 m,and the waterway in the bridge area is Ⅰ-(1)waterway.The main navigation holes of the bridge are based on the anti-collision standards for the representative ship types of 50 000 t container ships and 100 000 t bulk carriers,and the representative fleet of 16×3 000 t inland river fleet.The anti-collision facilities are made of steel-composite floating structure,which has the characteristics of complex structure,large plane size and heavy weight.The overall construction plan has been adopted to achieve safe,high-quality,and fast installation,which involves segmented processing and manufacturing in the factory,disassembly after overall pre-assembly,and then moving each segment to the harbor basin through a gantry crane.The segments are assembled into large sections in the harbor basin and towed by a tugboat to the bridge site,where they are bolted together as a whole.
