辽河特大桥为跨越辽河的主跨436m钢箱梁斜拉桥,主桥北侧边跨钢箱梁最大起吊重量达258t,选用500t浮吊进行吊装。由于边跨地处浅滩区,在枯水季节浮吊无法正常进入边跨水域进行梁段吊装。通过选择合理的吊装施工工艺,成功完成了边跨辅助跨梁段的吊装。
The Liaohe River Bridge is a 436m steel box girder cable-stayed bridge spanning the Liaohe River. The maximum lifting weight of the steel box girder on the north side of the main bridge is 258t, which is hoisted by 500t floating crane. As the edge of cross-Shallow area, floating in the dry season can not normally enter the side of the cross-section of beam lifting. By selecting a reasonable hoisting construction technology, the cross-section of the side span is completed successfully.
