Steel pipe arch construction method
The invention discloses a steel pipe arch construction method, which belongs to the technical field of arch bridge construction, and comprises the following steps of bracket erection, arch rib section size inspection, arch rib mounting and positioning, arch rib section welding, steel pipe arch outer surface anti-corrosion treatment and temporary bracket removal. A temporary support is built on a main bridge which is poured in advance to support arch rib sections, and an operation protection platform at the top of the support provides protection in the welding process to protect vehicles on an existing road below; meanwhile, before the arch rib sections are hoisted, the out-of-roundness adjusting device is used for correcting the arch rib sections subjected to size out-of-roundness inspection, the arch rib sections are located through the locating device after being hoisted to the support, the arch rib sections subjected to slab staggering are corrected through the slab staggering adjusting device, and the arch bridge installation precision and the construction quality are improved. The method is particularly suitable for arch bridge assembly above the existing road which is not cut off, normal operation of vehicles is not affected, and economic benefits are improved.
本发明公开了一种钢管拱施工方法，属于拱桥施工技术领域，包括以下步骤：支架搭设‑拱肋节段尺寸检查‑拱肋安装定位‑焊接拱肋节段‑钢管拱外表面防腐处理‑拆除临时支架。通过在预先浇筑完工的主桥上搭建临时支架支撑拱肋节段，支架顶部的操作防护平台在焊接过程中提供防护，保护下方既有道路上的车辆；同时，拱肋节段吊装前对检查尺寸失圆的利用失圆调整装置矫正，拱肋节段吊至支架上后通过定位装置定位，采用错台调整装置对出现错台的拱肋节段矫正，提高了拱桥安装精度及施工质量。本发明尤其适用于在未断交的既有道路上方进行拱桥拼装，不影响车辆正常运行，提高了经济效益。
