Channel-crossing large-span trestle construction method
The invention provides a channel-crossing large-span trestle construction method which comprises the following steps of S1, carrying out backfield pre-assembly on a supporting steel structure of a trestle, and assembling a plurality of truss units into a main span unit and a side span unit, S2, after pre-assembling of the supporting steel structure is completed, completing hoisting of the side span units on the two sides through a floating crane, S3, after hoisting of the side span units is completed, using a movable crane for entering the side span units to be matched with the floating crane,jointly suspending the main span units at the two ends, and assisting the main span units and the side span units to complete assembling. According to the channel-crossing large-span trestle construction method, the construction difficulty of the large-span trestle can be reduced, and the working efficiency of trestle construction is improved.
本发明创造提供了一种跨航道大跨度栈桥施工方法，包括如下步骤：S1，对栈桥的支撑钢结构进行后场预拼装，将多个桁架单元拼装成主跨单元和边跨单元；S2，在支撑钢结构预拼装完成后，利用浮吊完成两侧边跨单元的吊装；S3，在完成边跨单元吊装后，利用可移动吊车进入边跨单元，与浮吊配合，两端分列共同悬吊主跨单元，协助主跨单元与边跨单元完成拼装。本发明创造所述的一种跨航道大跨度栈桥施工方法，能降低大跨度栈桥的施工难度，提升栈桥施工的工作效率。
