Abstract

The invention discloses a construction method of a cable bent tower stay cable installation system, and relates to the technical field of bridge engineering. The construction method comprises the following steps: 1, mounting a tower top embedded component; 2, mounting an upper bracket of a tower top lifting traction operation platform; 3, mounting a beam end pressure anchor traction operation platform; 4, carrying out tower top cable hanging; 5, performing beam end anchor pressing; and 6, disassembling the construction platform. The construction method solves the problem that large hoisting equipment cannot be installed due to limited tower top space, connects a support system of an operation platform through embedded components, and mounts a power device, thus solving lifting and tractionof stay cables; compared with hoisting measures such as mounting a tower crane or a bracket, the cost investment and the time cost are saved; and the two parallel rails are arranged on the beam faceand used for advancing of the operation platform traction frame, so that the position of the operation platform can be adjusted at any time, and the operation platform can be flexibly placed in place,and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a construction method for a cable-stayed cable installation system of a cable tower. Background technique [0002] The stay cable is a load-bearing component with one end hung on the top of the tower and the other end anchored on the bridge beam. Therefore, in the installation and construction of the stay cable, it mainly includes 1. Two parts of the anchorage construction of the stay cables on the bridge girder body. At present, tower ends of cable-stayed cables are mostly hung with large-scale mechanical equipment such as tower cranes. The usual practice is to install tower cranes or brackets next to the main tower to complete the hoisting of cable-stayed cables, the entry, assembly, and erection of brackets for mechanical equipment, etc. Both require a lot of time and are expensive. At the same time, if the main tower of the bridge is located in Hanoi ...
