上海长江大桥主通航孔桥采用导向架、套箱与围堰结合、透水模板布、索塔爬架内设置密闭围挡和喷雾系统、承插式临时墩、防退扭千斤顶等技术措施,成功解决了长江口水域大跨全漂浮超宽钢斜拉桥施工难题。
Many technologies applied to the main bridge construction of the Shanghai Changjiang Channel Project,including the guiding frame,combination of collision case and cofferdam,water-penetration formwork cloth,the wind-free closure and spraying system, pulling-and-insertion temporary pier,anti-torsion jack,etc.These key technologies help to overcome the severe environment in Changjiang estuary to building the long-span,ultra-width and completely floating steel bridge.
