Intelligent control system and method for closure of large-span steel truss girder cable-stayed bridge
The invention relates to a large-span steel truss girder cable-stayed bridge closure intelligent control system and method, and the system employs a Beidou positioning instrument, a wireless inclinometer, an IMU sensor and the like to form the closure intelligent control system, reduces the difficulty of construction measurement, and improves the measurement efficiency. According to the method, the state of the closure gap is analyzed through data obtained by the automatic monitoring system, the construction adjustment control force is analyzed, the state of the closure gap is adjusted through the full-automatic hydraulic jack, and midspan closure of the large-span steel truss girder cable-stayed bridge is achieved in combination with fine adjustment measures. According to the method, the waiting operation time of large cantilever construction is shortened, the problems that the construction efficiency is low, and closure adjustment measures are not synchronous are solved, and accurate closure of the large-span steel truss girder cable-stayed bridge is achieved.
本发明涉及一种大跨度钢桁梁斜拉桥合龙智能控制系统及方法，采用北斗定位仪、无线倾角仪和IMU传感器等组成合龙智能控制系统，减小施工测量的难度，提高了测量效率。本发明通过自动化监测系统得到的数据分析合龙口状态并进行施工调整控制力分析，采用全自动液压千斤顶调整合龙口状态，结合微调措施实现大跨度钢桁梁斜拉桥的跨中合龙。该方法有助于减少大悬臂施工等待作业时间，解决施工效率较低，合龙调整措施不同步等问题，实现大跨度钢桁梁斜拉桥的精确合龙。
