Construction method for high-tower large-span upper cross beam of single-tower asymmetric cable-stayed bridge
The invention discloses a construction method for a high-tower large-span upper cross beam of a single-tower asymmetric cable-stayed bridge, which can greatly reduce the material consumption and save the engineering cost by implementing the construction method, and ensures the welding quality of a bracket by utilizing an integral hoisting mode after a bracket is welded on the ground; an unloading block is adopted on site to replace a conventional gas cutting bracket cushion block, so that the working efficiency is improved, and the risk of high-altitude welding operation of constructors is effectively reduced.
本发明公开了一种独塔不对称斜拉桥高塔大跨度上横梁施工方法，本工法的实施可大大减少材料的用量，节约工程成本，牛腿支架在地面焊接完成后利用整体吊装的方式进行安装，保证了牛腿的焊接质量；现场采用卸荷块代替以往气割牛腿垫块的方式，提高了工作效率，有效减少施工人员高空焊接作业的风险。
