Synchronous construction method for tower beams of special-shaped steel tower cable-stayed bridge
The invention belongs to the technical field of bridge design and construction, and particularly relates to a special-shaped steel tower cable-stayed bridge tower beam synchronous construction method which comprises the following steps that a cable-stayed bridge main beam support, a steel tower support and a gantry crane foundation are synchronously erected; a gantry crane rail is laid on the gantry crane foundation, and a gantry crane is installed; mounting a steel-concrete combined section of the swivel steel tower and pouring concrete; installing a swivel steel tower T1 section, and testing a swivel; a cable-stayed bridge main beam is poured, and the remaining steel tower sections are spliced section by section through the gantry crane; mounting a latticed column and a latticed column jack, and vertically rotating and closing the steel tower; stay cables are installed and tensioned, and accessory structures are dismantled; and bridge deck pavement is installed, and construction of the special-shaped steel tower cable-stayed bridge is completed. The method has the beneficial effects that synchronous construction of a bridge tower and a bridge beam is achieved, and the problem that the construction period of the bridge is short is solved.
本发明属于桥梁设计施工技术领域，尤其涉及一种异形钢塔斜拉桥塔梁同步施工方法，包括以下步骤：同步搭设斜拉桥主梁支架、钢塔支架、龙门吊基础；并在龙门吊基础上铺设龙门吊轨道，安装龙门吊；安装转体钢塔钢混结合段并浇筑混凝土；安装转体钢塔T1节段，试转体；浇筑斜拉桥主梁，通过龙门吊逐节段拼装剩余钢塔节段；安装格构柱、格构柱千斤顶，对钢塔竖转合龙；安装并张拉斜拉索，拆除附属结构；安装桥面铺装，完成异形钢塔斜拉桥施工。本发明的有益效果是：实现了桥梁塔、梁同步施工，解决了桥梁施工工期紧的难题。
