Large-span arch bridge original shape resetting installation control method
The invention discloses a large-span arch bridge original shape reset installation control method, and relates to the technical field of bridges. Comprising the steps that S1, a three-dimensional laser scanner is used for collecting three-dimensional manufacturing linear postures of all arch rib sections in a pre-splicing factory; s2, the collected linear posture is converted into a bridge site installation posture, and therefore the target posture for installation of each arch rib section is obtained; s3, the arch bridge is installed according to the installation target postures of all the arch rib sections, whether all the arch rib sections reach the target postures or not is judged, if yes, installation is completed, and if not, the step S4 is executed; and S4, performing target posture adjustment on the arch rib sections which do not reach the target posture, reversely and accurately solving a three-way jack adjustment value by identifying a difference value between the current posture and the target posture, and completing installation after adjustment is completed. According to the invention, the three-dimensional attitude precision and the construction efficiency required by the installation of the large-span arch bridge are improved, the labor and safety management cost is saved, the construction quality is ensured, and the safety operation risk is reduced.
本发明公开了一种大跨度拱桥原形复位安装控制方法，涉及桥梁技术领域。包括：S1.利用三维激光扫描仪采集预拼厂内对各个拱肋节段的三维制造线形姿态；S2.将采集的线形姿态转换为桥位安装姿态，从而获取各个拱肋节段进行安装的目标姿态；S3.利用各个拱肋节段进行安装的目标姿态对拱桥进行安装，并判断各个拱肋节段是否达到目标姿态，若是则完成安装，若否则进入S4；S4.对于未达到目标姿态的拱肋节段进行目标姿态调整，通过识别现在姿态与目标姿态的差值，反向精确求出三向千斤顶调整值，调整完毕则完成安装。本发明提高了安装大跨拱桥所需的三维姿态精度及施工效率，节省了人工和安全管理成本，保证了施工质量，降低了安全操作风险。
