襄阳汉江三桥跨南大堤桥菱形挂篮换幅横移关键技术,即江侧挂篮底篮及侧模分别采用卷扬机整体下放,主桁架先整体纵移后横移的方式进行挂篮的拆除及换幅周转。通过工程实践证明,该技术能大大降低施工难度、加快拆除进度、减少施工设备投入、保证施工安全和降低施工成本。 The key technology for the crossbar transfer and cross-over of rhombus-shaped hanging basket in Hanjiang River Bridge in Xiangyang Hanjiang River is that the hoisting machine is used as the bottom basket and the side molds of the river side hanging basket, respectively, and the main trusses are vertically moved and traversed first, And change turnover. The engineering practice proves that the technology can greatly reduce the construction difficulty, speed up the demolition progress, reduce the investment in construction equipment, ensure the construction safety and reduce the construction cost.
