Construction method of curved-surface special-shaped cable bent tower
The invention discloses a construction method of a curved-surface special-shaped cable bent tower. The construction method comprises the step of simultaneously constructing a first lower tower column and a second lower tower column. The first lower tower column and the second lower tower column are constructed section by section to form a first middle tower column and a second middle tower column, and a temporary supporting axial force pre-adding device is installed between the first middle tower column and the second middle tower column. Constructing on the first middle tower column and the second middle tower column section by section to form a first upper tower column and a second upper tower column; and the first upper tower column and the second upper tower column are anchored correspondingly, and the curved-surface special-shaped cable bent tower with the orthographic projection in the transverse bridge direction being in a herringbone shape is formed. The temporary supporting axial force pre-adding device is installed between the first middle tower column and the second middle tower column, when the first middle tower column and the second middle tower column are in the separated state, the stability of the tower column structure is ensured, the construction quality is kept, the construction steps are simple, operation is convenient, and the construction efficiency is improved.
本发明公开了一种曲面异形索塔施工方法，包括：同时施作第一下塔柱和第二下塔柱。在所述第一下塔柱和所述第二下塔柱上分别逐节段施作形成第一中塔柱和第二中塔柱，在所述第一中塔柱和所述第二中塔柱之间安装临时支撑预加轴力装置，在所述第一中塔柱和所述第二中塔柱上分别逐节段施作形成第一上塔柱和第二上塔柱；分别锚固所述第一上塔柱和所述第二上塔柱，形成在横桥向的正投影呈人字形的曲面异形索塔。本发明通过在第一中塔柱和第二中塔柱之间安装临时支撑预加轴力装置，在第一中塔柱和第二中塔柱之间处于分离状态时，确保塔柱结构的稳定，保持施工质量，且施工步骤简单、作业方便，提高了施工效率。
