Bridge tower lower tower column non-landing support construction method
The invention relates to a bridge tower lower tower column non-landing support construction method which comprises the following specific steps: mounting a cable-stayed support device at the top of a bearing platform, mounting bracket devices on two side walls, parallel to the longitudinal bridge direction, of the bearing platform, and mounting a steel back ridge support frame, a steel back ridge and a shaped steel template on the bracket devices; a lower truss fixing device and a lower truss are mounted on the bracket device; a plurality of stay cable assemblies are installed on the cable-stayed supporting device in the transverse bridge direction through cable saddles, each stay cable assembly is divided into a plurality of stay cables through a stay cable beam splitter, the stay cables are connected with a lower truss, a cable force monitoring device and a pre-pressing sand bag are installed on each stay cable, and the stay cables are tensioned and anchored through a tensioning machine tool. And removing the sandbag, and pouring concrete at the set-shaped steel template to finish the construction of the lower tower column. According to the cable-stayed device, part of vertical force generated by construction of the lower tower column is converted into vertical force of the cable-stayed device to the bearing platform, the vertical supporting capacity of the bracket device is greatly improved, and the pouring quality of the lower tower column is guaranteed.
本发明是一种桥塔下塔柱不落地支撑施工方法，具体步骤为：在承台顶部安装斜拉支撑装置，在承台平行于纵桥向方向的两侧壁上安装托架装置，托架装置上安装钢背楞支撑架、钢背楞、定型钢模板；在托架装置上安装下桁架固定装置、下桁架；斜拉支撑装置沿横桥向方向通过索鞍安装若干斜拉索组件，每个斜拉索组件均通过斜拉索分束器分出若干斜拉索，斜拉索连接下桁架，每根斜拉索上均安装有索力监控装置，预压沙袋，采用张拉机具对斜拉索进行张拉、锚固；撤除沙袋，在定型钢模板处浇筑混凝土，完成下塔柱的施工。本发明的斜拉装置将部分下塔柱施工产生的竖向力转化为斜拉装置对承台的竖向力，大大提高托架装置的竖向支撑能力，保证了下塔柱的浇筑质量。
