Construction method for upper tower column of variable-cross-section special-shaped cable bent tower
The invention relates to a construction method for a tower column on a variable-cross-section special-shaped cable bent tower. The construction method comprises the steps that an accurate positioning auxiliary structure of an annular prestressed pipeline is constructed; mounting the circumferential prestressed pipeline; assembling a hoisting anti-deformation bracket of the stiff framework; constructing an accurate pre-splicing guide auxiliary structure of the stiff skeleton; mounting a stiff framework and binding reinforcing steel bars; mounting a steel corbel, a steel anchor box and a steel anchor beam; the adjustable assembly type truss steel membrane is installed; pouring and curing upper tower column concrete; tensioning the circumferential prestressed tendons; constructing a stay cable mounting structure; stay cables are installed and tensioned; and mounting the next section of upper tower column. The hoisting anti-deformation support has the beneficial effects that the hoisting anti-deformation support is ingenious in structural design, convenient to assemble and disassemble, recyclable, high in turnover efficiency and capable of adapting to hoisting of stiff skeletons with different section sizes, the hoisting problem of tower columns on variable-section special-shaped cable bent towers is solved, and the hoisting anti-deformation support has wide application prospects.
本发明涉及一种变截面异形索塔上塔柱的施工方法，包括步骤：环向预应力管道的精确定位辅助结构施工；环向预应力管道安装；劲性骨架的吊装防变形支架拼装；劲性骨架的精确预拼导向辅助结构施工；劲性骨架安装及钢筋绑扎；钢牛腿、钢锚箱及钢锚梁安装；可调装配式桁架钢膜安装；上塔柱混凝土浇筑及养生；环向预应力筋张拉；斜拉索安装结构施工；斜拉索安装及张拉；安装下一节上塔柱。本发明的有益效果是：采用吊装防变形支架，结构设计巧妙，装拆便捷，可循环利用，周转效率高，同时可以适应不同截面尺寸的劲性骨架的吊装，解决了变截面异形索塔上塔柱的吊装难题，具有广阔的应用前景。
