Cable-stayed bridge old cable auxiliary tower top hanging bracket cable replacement construction method
The invention discloses a cable-stayed bridge old cable auxiliary tower top hanging bracket cable replacement construction method which comprises the following steps that S1, construction preparation is conducted, cable replacement equipment is installed, the state of the cable replacement equipment is checked, and a new cable is unfolded at the designated bridge floor position; s2, installing an in-tower traction rope and a sliding hoisting ring, and determining hoisting point positions of a tower top steel wire rope and a new rope; s3, the new cable is gradually lifted to the tower end under the traction effect; s4, tower end installation and temporary anchoring are conducted on the new cable; s5, bridge end installation and anchoring are conducted on the new cable; s6, the tower end is tensioned and anchored step by step; according to the construction method, the old cable on the upper portion is used for assisting the tower top hanging bracket to replace the cable, and the construction method is beneficial to preventing the new cable from slipping off in the hoisting process to injure construction workers or damage a beam plate; and meanwhile, a new cable installation tower end anchor head can be accurately positioned and quickly enter a cableway pipe, the construction safety is improved, and the construction efficiency is improved.
本发明公开了一种斜拉桥旧索辅助塔顶吊架换索施工方法，包括以下步骤:S1：进行施工准备，将换索设备安装好，并对换索设备状态进行检查，并将新索在指定桥面位置展开；S2：安装塔内牵引绳及滑动吊环，确定塔顶钢丝绳与新索的吊点位置；S3：新索在牵引作用下逐步提升至塔端；S4：对新索进行塔端安装并临时锚固；S5：再将新索进行桥端安装并锚固；S6：塔端逐步张拉并锚固；本发明利用上部旧索辅助塔顶吊架进行换索，该施工方法有利于防止新索吊运过程中发生滑落，砸伤施工工人或砸坏梁板；同时有利于新索安装塔端锚头准确定位快速进入索道管，提升施工的安全性，提高了施工工效。
