Precise positioning method for first steel tower section of ultrahigh multi-limb steel-concrete combined tower column
The invention discloses a method for accurately positioning a first steel tower section suitable for an ultrahigh multi-limb steel-concrete combined tower column. Arranging a measurement working base point corresponding to each tower limb; respectively rotating a group of tower cranes in four directions, and measuring the influence quantity of each tower crane on the tower column by the total station; all the tower limbs are synchronously constructed to the steel-concrete combined section, and all the tower limbs are connected into an integral structure through a locking structure; an automatic axial force monitoring instrument is mounted on the locking structure; arranging temperature monitoring points, establishing a tower limb overall temperature field, and monitoring tower limb top displacement caused by temperature change; establishing models of different hoisting weights and directions of the tower crane, internal and external temperature fields of a tower limb and offset of the tower limb, and raising neutral free positions of a single tower limb and an integral structure; building a tower limb top control reference; and the first section steel tower is positioned. According to the method, the mounting and positioning precision of the first steel tower section of each tower limb at the steel-concrete combined section is effectively improved.
本发明公开了一种该适用于超高多肢钢混组合塔柱的首个钢塔节段精确定位方法，包括以下步骤；对应每个塔肢布置测量工作基点；将一组塔机分别旋转四个方向，全站仪测定各塔机对塔柱的影响量；所有塔肢同步施工到钢混结合段处，采用锁定结构将所有塔肢连成一个整体结构；在锁定结构上安装轴力自动化监测仪器；布置温度监测点，建立塔肢整体温度场，实施温变引起塔肢顶部位移监测；建立塔机不同吊重和方位、塔肢内外温度场与塔肢偏移量模型，提高单独塔肢和整体结构的中性自由位置；塔肢顶部控制基准建立；定位首节段钢塔。本发明有效提高钢混结合段处每个塔肢的首个钢塔节段安装定位精度。
