摘要
在墩旁托架的最外侧组拼钢桁梁节段单元,每组拼1个节间即通过千斤顶纵向拖拉1个节间长度,如此循环完成武汉天兴洲公铁两用长江大桥3号主塔墩墩顶4节间钢桁梁架设,解决了倒Y形主塔下方吊装的难题。
The steel truss girder block units were first assembled at the outermost parts of the pier-side brackets. A panel length of the assembled steel truss girder was then longitudinally hauled by jacks after assembling of each panel of the girders was completed. Repeating in such a way, the erection of all the four panels of the steel truss girders at the top of pylon pier No. 3 of Wuhan Tianxingzhou Changjiang River Rail-cum-Road Bridge was to be carried out and the problem of lifting right under the inverted Y-shape pylon of the Bridge could be therefore tackled.
