Accurate butt-joint positioning method for anchor pull rods of inclined steel-concrete combined section
The invention discloses an accurate butt-joint positioning method for anchor pull rods of an inclined steel-concrete combined section. The method comprises the steps that S1, an embedded support is arranged on a lower tower column in an embedded mode; s2, an anchor beam positioning frame is welded to the embedded support; s3, assembling the anchor pull rod and the components of the anchor pull rod into anchor pull rod sheet bodies, and hoisting the anchor pull rod sheet bodies to an anchor beam positioning frame in a split manner for positioning; s4, the steel-concrete combined section is hoisted to be aligned and assembled with the anchor pull rod sheet body; s5, the anchor pull rod is pulled upwards to enable the upper end of the anchor pull rod to penetrate out of the top of the anchor box; and S6, after concrete is poured and formed, the anchor pull rods are tensioned in sequence to reach the designed tensioning force, and installation construction of the anchor pull rods of the steel-concrete combined section of the steel cable bridge is completed. According to the steel-concrete combined section and anchor pull rod assembly split positioning and mounting process method, the anchor pull rod assembly is hoisted in a split mode, the high requirement of overall hoisting for the hoisting capacity of equipment is avoided, and the process method is mainly suitable for the situation that the hoisting capacity of a tower crane is not enough to meet the overall hoisting of the steel-concrete combined section and the anchor pull rod assembly; and the use cost of hoisting equipment is effectively saved.
本发明公开一种倾斜式钢混结合段的锚拉杆精确对接定位方法，包括：S1，将预埋支架预埋设置在下塔柱上；S2，将锚梁定位架焊接在预埋支架上；S3，锚拉杆及其组件组装成锚拉杆片体并分片吊装至锚梁定位架上进行定位；S4，将钢混结合段吊装与锚拉杆片体对准装配；S5，将锚拉杆向上牵引使其上端穿出锚箱的顶部；S6，混泥土浇筑成型后，对锚拉杆进行依次进行张拉，使之达到设计张拉力，完成钢索桥钢混结合段锚拉杆安装施工。本发明是一种钢混结合段与锚拉杆组件分体定位安装工艺方法，锚拉杆组件分片吊装，避免了整体吊装对设备起重能力的高要求，主要适用于吊塔起重能力不足以满足钢混结合段与锚拉杆组件整体吊装的情况，有效节约了起重设备使用费用。
