Problems solved by technology

In the construction of long-span cable-stayed bridges, the length of a single cable-stayed cable can reach hundreds of meters, and the weight can reach tens of tons. If the environment is dangerous and the water level drop is large, it will bring great difficulties to the construction of the cable-stayed bridge, especially It is the installation and construction of cable stays, which increases the difficulty, resulting in a longer construction period

Abstract

The invention provides a stay cable tensioning construction method. The stay cable tensioning construction method comprises the following steps that a tower inner construction platform is built at a hollow portion inside a cable tower, and a tower outer construction device is arranged at the top of the cable tower; a tensioning assembly is arranged on the cable tower by utilizing the tower inner construction platform and the tower outer construction device, the tensioning assembly is enabled to correspond to the mounting positions of stay cables on the cable tower, the tensioning assembly is connected with one stay cable which is temporarily anchored so as to tension the corresponding stay cable; when the internal space of the cable tower is larger than the occupied space of the tensioning assembly, the stay cables on the two sides, in the direction of a bridge, of the cable tower are synchronously tensioned from the tower end. The stay cable tensioning construction method has the advantage that corresponding tensioning methods can be adapted to the stay cables of the different cable towers so as to shorten the construction period.

Description

technical field [0001] The application relates to bridge construction, in particular to a cable-stayed tensioning construction method. Background technique [0002] The installation of cable-stayed cables is an important part of the construction of cable-stayed bridges. Due to the influence of terrain and environmental factors, the installation and construction of cable-stayed cables also have certain differences. In the construction of long-span cable-stayed bridges, the length of a single cable-stayed cable can reach hundreds of meters, and the weight can reach tens of tons. If the environment is dangerous and the water level drop is large, it will bring great difficulties to the construction of the cable-stayed bridge, especially It is the installation and construction of the stay cables, which increases the difficulty, resulting in a longer construction period. In the prior art, in order to ensure the stability and reliability of the cable-stayed bridge, one end of the ...
