Novel structure of main tower in multi-tower suspension bridge and construction method of novel structure
The invention provides a novel structure of a main tower in a multi-tower suspension bridge and a construction method of the novel structure. The novel structure comprises the main tower, a plurality of inclined slings, a first stiffening beam and a plurality of main cable saddles. The plurality of main cable saddles are vertically fixed on the tower top of the middle main tower in parallel at intervals along the transverse direction of the middle main tower; the multiple inclined slings are obliquely arranged on the two sides of the middle main tower respectively, the upper end of each inclined sling is anchored in a lower bearing plate on the top of the middle main tower, and the lower end of each inclined sling is connected to the corresponding first stiffening beam; the first stiffening beams are arranged on the two sides of the middle main tower respectively. According to the structure and method, the longitudinal flexural rigidity of the main tower is improved through components of the structure, the overall appearance of the whole bridge is not affected, construction is convenient, and procedures are not increased.
本申请提供一种多塔悬索桥中主塔新型结构及其施工方法，其包括中主塔、多根斜吊索、第一加劲梁以及多个主索鞍；多个主索鞍沿中主塔的横向而平行间隔地竖直固定于中主塔的塔顶上；多根斜吊索分别倾斜地设置于中主塔的两侧，且每根斜吊索的上端锚固于中主塔塔顶的下承板中，且下端连接于相对应的第一加劲梁上；第一加劲梁分别设置于中主塔的两侧。该构造及方法利用结构自身部件提升中主塔纵向抗弯刚度，不影响全桥整体外观、施工方便且不增加工序。
