Novel steel-concrete combined stay cable tower anchoring structure and construction method thereof
The invention discloses a novel stay cable tower anchoring structure in a steel-concrete combined form. The novel stay cable tower anchoring structure is used for anchoring stay cables on a cable-stayed bridge in a cable tower anchoring area. The novel steel-concrete combined type cable bent tower anchoring structure is provided with a plurality of cable bent tower anchoring structure sections, and each cable bent tower anchoring structure section comprises a steel box, a plurality of cable bent tower anchoring structures and a plurality of cable bent tower anchoring structures, wherein each cable bent tower anchoring structure section comprises a central cavity and a plurality of side cavities; the stay cable anchoring assemblies are connected with the two opposite first side walls, in the longitudinal direction of the bridge, of the central cavity. Each group of stay cable anchoring assemblies are symmetrically distributed in the central cavity in a spatial crossing manner and comprise at least four stay cable anchoring assemblies which are obliquely arranged; and the concrete is poured into the central cavity outside the stay cable anchoring assembly. The hoop effect of the central cavity of the steel box on concrete is utilized, and the bearing capacity of the cable bent tower anchoring area is obviously improved. The invention further provides a construction method of thestay cable tower anchoring structure in the steel-concrete combined form.
本发明公开一种新型钢混组合形式的斜拉索索塔锚固结构，用于在索塔锚固区锚固斜拉桥上的斜拉索；该新型钢混组合形式的索塔锚固结构具有多个索塔锚固结构节段，索塔锚固结构节段包括：钢箱，其具有一中央腔室和多个纵桥向对称分布在中央腔室两侧的侧腔室；至少一组斜拉索锚固组件，该组斜拉索锚固组件连接中央腔室纵桥向相对的两第一侧壁；每组斜拉索锚固组件在中央腔室中对称且空间交叉分布，且包括至少四个倾斜设置的斜拉索锚固组件；混凝土，其灌注于斜拉索锚固组件外的的中央腔室中。本发明利用了钢箱中央腔室对混凝土的“套箍效应”，索塔锚固区的承载能力明显提高。本发明还提供了该钢混组合形式的斜拉索索塔锚固结构的施工方法。
