Stay cable hanging method under tower, beam and cable synchronous construction condition of extradosed cable-stayed bridge
The invention provides a stay cable hanging method under the condition of tower, beam and cable synchronous construction of an extradosed cable-stayed bridge, and belongs to the technical field of building construction. The method comprises the steps that preparation work before cable hanging is conducted, sleeve hoisting work is conducted after preparation is completed, a circulating traction device is arranged to facilitate follow-up steel strand cable hanging, cable hanging work of the steel strands is conducted till cable hanging of all the steel strands is completed, and steel strand tensioning work and sleeve fixing are conducted after cable hanging is completed. Then temporary protection, cable force detection and cable force damping work are conducted through waterproof cloth and the like, and finally protection treatment of the stay cable is conducted; by means of the circulating traction system in the method, the steel strand is more stable and faster in the cable hanging process, the number of invested equipment and workers is small, the occupied space for hanging the single steel strand is small, the working procedure is simple, and the installation speed of the stay cable is higher.
本发明提出了一种矮塔斜拉桥塔梁索同步施工条件下斜拉索挂设方法，属于建筑施工技术领域；本方法包括在挂索前的准备工作，准备完成后进行套管的吊装工作，设置循环牵引装置方便后续钢绞线挂索，进行钢绞线的挂索工作直至所有钢绞线完成挂索，挂索完成后进行钢绞线张拉工作以及套管的固定，随后通过防水布等进行临时防护、索力检测以及索力减震工作，最后进行斜拉索的防护处理；通过该方法中循环牵引系统使得钢绞线在挂索过程中更为稳定快捷，且所投入的设备以及工作人员较少，单根钢绞线挂索占用场地较小，工序简单，使得斜拉索的安装速度更加快捷。
