Large-span lifting basket arch bridge suspender installation construction method
The invention relates to the field of bridge suspender construction, and particularly discloses a large-span basket arch bridge suspender installation construction method which comprises the following steps: S1, carrying out preparation work before construction; step S2, mounting a suspender, which mainly comprises the following steps: step S21, hoisting the suspender to a corresponding position of an arch rib; s22, a hoisting machine penetrates through a preset hole in the arch rib to enable a hoisting rod to penetrate through a tower end embedded pipe, and a tower end nut is installed; s23, a pin shaft is installed at the lower end of the hanging rod; s3, arch end tensioning equipment is installed, debugged and checked, then symmetrical tensioning is conducted in batches according to requirements, and fastening nuts are tightened after the arch end tensioning equipment is tensioned to the designed cable force; and S4, the step S3 is repeated until tensioning of all the suspenders is completed. The hoisting rod is hoisted by the winch, so that the hoisting device is more convenient to mount and arrange; meanwhile, by adopting the hoisting mode of the winch, the cost is better reduced, and the economy is saved.
本发明涉及桥梁吊杆施工领域，具体地说，公开了一种大跨度提篮拱桥吊杆安装施工方法，其步骤如下：步骤S1、进行施工前的准备工作；步骤S2、进行吊杆的安装，其主要包括如下步骤：步骤S21、将吊杆吊运到拱肋相应位置；步骤S22、通过卷扬机穿过拱肋处的预设孔将吊杆穿过塔端预埋管，并安装塔端螺母；步骤S23、在吊杆的下端安装销轴；步骤S3、安装拱端张拉设备并调试检查，随后按照要求分批对称张拉，待张拉到设计索力后，打紧紧定螺母；步骤S4、重复步骤S3，直至完成对于所有吊杆的张拉。本发明采用卷扬机对吊杆进行吊装，不仅在安装设置时更为方便；同时，通过采用卷扬机的吊装方式，还较佳的降低了成本，节约了经济。
