Folding web groove-shaped steel anchor box type combined cable bent tower anchoring structure and construction method
The invention discloses a folded-web groove-shaped steel anchor box type combined cable bent tower anchoring structure and a construction method, and relates to the technical field of bridge structures, the folded-web groove-shaped steel anchor box type combined cable bent tower anchoring structure comprises a plurality of folded-web groove-shaped steel anchor boxes which are connected in an up-down stacked mode, a concrete tower wall and stay cables; the concrete tower wall is connected to the outer side of the folded web groove-shaped steel anchor box in a surrounding mode. The folded web groove-shaped steel anchor box comprises two folded webs and two groove-shaped steel anchor boxes; the two ends of the zigzag web are connected with the two groove-shaped steel anchor boxes correspondingly, and an annular closed structure is defined. The concrete tower walls comprise end tower walls and side tower walls, the end tower walls and the groove-shaped steel anchor boxes are arranged at intervals, and the side tower walls are connected with the groove-shaped steel anchor boxes; the stay cable penetrates through the end tower wall and is connected with the groove-shaped steel anchor box. The method can reduce the tensile stress of the end tower wall concrete, improves the steel utilization rate, is convenient to construct, and is suitable for stay cable arrangement of multiple anchor heads and space cable surfaces.
本申请公开了一种折腹槽形钢锚箱式组合索塔锚固结构以及施工方法，涉及桥梁结构的技术领域，其包括若干节段上下垒叠连接的折腹槽形钢锚箱、混凝土塔壁以及斜拉索；混凝土塔壁围设连接于折腹槽形钢锚箱外侧；折腹槽形钢锚箱包括两片折形腹板与两个槽形钢锚箱；折形腹板的两端分别与两个槽形钢锚箱连接，围合形成环形封闭结构；混凝土塔壁包括端塔壁与侧塔壁，端塔壁与槽形钢锚箱之间间隔设置，侧塔壁与槽形钢锚箱连接；斜拉索穿设于端塔壁，并与槽形钢锚箱连接。本申请能够减小端塔壁混凝土的拉应力，提高钢材利用率，施工便捷，适应多锚头、空间索面的斜拉索布置。
