Bridge tower vertical rotating system and construction method thereof
The invention discloses a bridge tower vertical rotating system and a construction method thereof. The bridge tower vertical rotating system comprises a vertical rotating device, a traction device anda vertical twisting system. The vertical twisting system is installed on a bridge pier on the side of the tower root of the bridge tower and used for being hinged to the tower root end of the bridgetower. The top end of the vertical rotating device is erected in the middle of the bridge tower, and the bottom end of the vertical rotating device is erected on the traction device. The fixing part of the traction device is erected on the horizontal pier and can vertically support the bottom end of the vertical rotating device, and a movable part is horizontally connected to the bottom end of thevertical rotating device; when the traction device acts, the bottom end of the vertical rotating device can be driven to move horizontally, and then the height of the tower head end of the bridge tower is changed. The bridge tower vertical rotating system and the construction method thereof can be applied to arch bridge vertical rotation construction in the process of crossing canyons, existing highways and existing railway lines and vertical rotation of various special-shaped prefabricated bridge towers including vertical bridge towers, vertical rotation construction and temporary back buckling towers, and have good application and popularization prospects.
本发明公开一种桥塔竖转系统及其施工方法，包括竖转装置、牵引装置和竖绞系统；所述竖绞系统安装于桥塔的塔根侧桥墩上，用于铰接桥塔的塔根端；所述竖转装置顶端架设于桥塔的中部，底端架设于牵引装置上；所述牵引装置固定部件架设于水平桥墩上可竖直支撑起竖转装置的底端，活动部件水平连接在竖转装置的底端；当所述牵引装置动作时，可带动竖转装置的底端作水平运动，进而改变桥塔的塔头端的高度；本发明可运用于跨峡谷、既有公路、铁路线时拱桥竖转施工，各类异形预制桥塔，包括竖直桥塔，竖转施工以及临时扣背塔的竖转，具有良好的推广应用前景。
