Main channel cross-sea bridge fusiform main tower structure and large segment construction method thereof
The invention provides a fusiform main tower structure of a main channel cross-sea bridge and a large section construction method thereof, and relates to the technical field of bridge construction. The main tower is composed of a bearing platform, a tower base, a lower tower column, a lower cross beam, a middle tower column, an upper cross beam, an upper tower column and a tower crown and is of an oval frame structure in the transverse bridge direction, and the transverse center distance between the tower columns is gradually changed from the tower bottom to the tower top. The construction method comprises the steps of construction stage division, tower column large section division, construction preparation, lower tower column construction, lower cross beam construction, middle tower column construction, upper cross beam construction, upper tower column construction, steel anchor beam and cable guide pipe construction, tower crown construction and construction tool dismantling. The construction period is shortened through large-stage construction, the construction efficiency is high, the safety is high, the steps are simple, the economic benefit is good, the engineering quality is guaranteed through symmetrical force adjustment of a cross arm system and whole-process monitoring analysis and finite element analysis, linear control is accurate, auxiliary parts are convenient to construct, mount and dismount and can be repeatedly used, high-altitude welding operation is little, and the construction period is shortened. The repairing workload is small.
本发明提出一种主航道跨海大桥梭形主塔结构及其大节段施工方法，涉及桥梁施工技术领域。主塔由承台、塔座、下塔柱、下横梁、中塔柱、上横梁、上塔柱和塔冠组成，横桥向为椭圆框架结构，各塔柱横向中心间距从塔底到塔顶渐变；施工方法为施工阶段划分、塔柱大节段划分、施工准备、下塔柱施工、下横梁施工、中塔柱施工、上横梁施工、上塔柱施工、钢锚梁及索导管施工、塔冠施工及拆除施工机具。本发明结构线形美观景观性好、大阶段施工缩短工期、施工效率高、安全性高、步骤简单、经济效益好、横撑体系对称调力及全过程监测分析与有限元分析保证工程质量、线形控制精确、辅助件施工安装拆卸方便可重复利用、高空焊接作业少、修补工作量小。
