Asymmetric erection construction method for cable-stayed and suspension cable cooperative system bridge
The invention relates to an asymmetric erection construction method for a cable-stayed and suspension cable cooperative system bridge, which comprises the following steps of: installing a pushing mechanism and a girder erection crane on a main tower on a shore, and pushing a side span steel girder to the position of a side pier; a midspan cable-stayed steel beam on one shore is erected through a cantilever of a beam erecting crane, and a pushing mechanism located on the first shore is synchronously dismantled in the period; the dismantled pushing mechanism is inversely used on the main tower on the opposite bank, and then the girder erecting crane is transferred to the main tower on the opposite bank; the side span steel beams on the opposite bank are pushed to the positions of the side piers through a beam erecting crane and a pushing mechanism, and main cable erecting is conducted synchronously during pushing construction of the side span steel beams on the opposite bank; erecting mid-span cable-stayed steel beams opposite to the bank by using a cantilever of a beam erecting crane, and mounting a suspender and a cable loading crane on a main cable; after the mid-span cable-stayed steel beam cantilever on the opposite bank is erected, the cable-loaded crane walks to the mid-span position to erect a mid-span suspension area steel beam; and the cable crane is split into two small cranes, the two small cranes are used for synchronously hoisting the closure section steel beam, and bridge erection is completed.
本申请涉及一种斜拉悬索协作体系桥梁非对称式架设施工方法，包括：在一岸的主塔上安装顶推机构和架梁吊机，将边跨钢梁顶推至边墩位置；再利用架梁吊机悬臂架设一岸中跨斜拉钢梁，期间同步拆除位于一岸的顶推机构；将拆除的顶推机构倒用至对岸的主塔上，再将架梁吊机转移至对岸的主塔上；利用架梁吊机和顶推机构将对岸的边跨钢梁顶推至边墩位置，对岸的边跨钢梁顶推施工期间同步进行主缆架设；再利用架梁吊机悬臂架设对岸中跨斜拉钢梁，同时在主缆上安装吊杆和缆载吊机；待对岸中跨斜拉钢梁悬臂架设完成后，缆载吊机走行至跨中位置架设中跨悬吊区钢梁；将缆载吊机拆分为两台小吊机，利用两台小吊机分别同步吊装合龙段钢梁，完成桥梁架设。
