System and method for adjusting posture of cable-stayed swivel bridge
The invention discloses a system and method for adjusting the posture of a cable-stayed swivel bridge. The system comprises a jacking device, an observation device and a beam end supporting device. When the posture of the cable-stayed swivel bridge is adjusted, the jacking device and the observation device are both arranged at the bottom of a lower rotating disc of the bridge body, and the posture of the bridge body is adjusted through jacking and observation; the beam end supporting devices are arranged below the two beam ends of the bridge body and abut against the beam ends of the bridge body to stabilize the beam ends. The method comprises the following steps of establishing a posture adjustment measurement control network, collecting initial data, installing a rotary table jacking and observing device, installing a beam end supporting device, adjusting the posture of a cable bent tower, temporarily fixing a rotary table, removing adjusting equipment, sealing an anchor through the rotary table, adjusting the posture of a beam end, constructing a beam end closure section and removing the adjusting equipment. The method has the beneficial effects that posture adjustment can be rapidly carried out after the cable-stayed bridge rotates in place, and the purpose that the posture of a bridge body meets the design precision requirement is achieved.
本申请公开了一种斜拉转体桥姿态调整系统及方法，其系统包括：顶升装置、观测装置以及梁端支撑装置；在进行斜拉转体桥姿态调整时，其中顶升装置以及观测装置均设置在桥体的下转盘底部，通过进行顶升以及观测，进行调整桥体姿态；其中梁端支撑装置设置在桥体的两梁端下方，将桥体的梁端顶住顶紧，进行稳定梁端。其方法包括如下步骤：建立姿态调整测量控制网、采集初始数据、安装转盘顶升及观测装置、安装梁端支撑装置、索塔姿态调整、转盘临时固定、撤除调整设备、转盘封锚、梁端姿态调整、梁端合拢段施工以及撤除调整设备。本申请的有益之处在于能够在斜拉桥转体就位后迅速实施姿态调整，实现桥体姿态达到设计精度要求。
