Steel plate hinged type segmented prefabricated assembled arch bridge and intelligent construction control method
The invention discloses a steel plate hinged type segmented prefabricated assembled arch bridge and an intelligent construction control method. The structure has two skewbacks, wherein a sliding inclined surface is formed on the mounting side of the skewback; a plurality of section arch rings are arranged in parallel, wherein the two ends of the segment arch ring are attached to the two sliding slopes correspondingly and are fixed in a pouring mode. The section arch ring comprises a plurality of segments of prefabricated wedge blocks; wherein a steel plate connecting piece is fixed on the top surface of the prefabricated wedge-shaped block through a bolt; hinge buckles are formed at the two ends of the steel plate connecting pieces, and the adjacent steel plate connecting pieces are connected through the hinge buckles. During construction, sensor monitoring data is collected, and calculation result is simulated and calculated according to an established arch bridge digital twinborn model and an arch construction load numerical value; then, the prefabricated arch ring is tensioned in a graded and segmented mode according to the arch construction load through intelligent numerical control tensioning equipment, and the linear shape and the internal force of the prefabricated arch ring are adjusted to be consistent with the design. Therefore, the problem that the bridge forming line shape is not matched with the designed line shape is solved.
本发明公开了一种钢板铰接式分段预制拼装拱桥及智能施工控制方法，拱座的数量为两个；拱座的安装侧形成有滑动斜面；节段拱圈的数量为多个，且并列布置；节段拱圈的两端分别与两个滑动斜面贴合，且浇筑固定；节段拱圈包括多段预制楔形块；预制楔形块顶面通过螺栓固定有钢板连接件；钢板连接件两端形成有铰接扣，相邻的钢板连接件通过铰接扣连接。在施工时，本发明通过采集传感器监测数据，根据建立的拱桥数字孪生模型和拱上施工荷载数值模拟计算的结果，通过智能数控张拉设备，根据拱上施工荷载分级分段张拉预制拱圈，调整其线形和内力与设计保持一致，解决成桥线形与设计线形不吻合的问题。
