摘要
苏通长江公路大桥为主跨1 088 m的钢箱梁斜拉桥,边跨及辅助跨梁段在工厂组拼成大块段,用大型浮吊安装。由于主桥通航净空高,传统桁架结构吊具难以满足国内现有浮吊吊高与吊重要求。提出苏通大桥边跨及辅助跨超大、超重钢箱梁节段轻型吊索具结构,并介绍吊索具设计与使用要点。
Sutong bridge is a cable-stayed bridge with a steel box girder and a main span of 1088 meters.Each back span large unit was fabricated by welding several deck segments together in factory, and was erected by floating crane. Due to the high navigational clearance of the main bridge, the traditional truss lifting device couldn＇t satisfy the requirement of domestic lifting cranes for this kind of lifting height and weight. Hence, a kind of lighter lifting device for erection of back span large units was accepted for this bridge. In this paper, the design and use of this lifting device is introduced.
