A method for installing a suspended flexible anchor ring at height

Abstract

The application provides a kind of high-altitude installation method of suspension type flexible anchor ring, comprising the following steps: placing flexible anchor ring on limiting support, lifting the limiting support so that the flexible anchor ring moves to the design position, and fixing the limiting support;Unscrew the bolt between the upper connecting plate and the corresponding end block, symmetrically install and tension the multiple tower ring cables close to the upper connecting plate, until the gap between the end blocks of the upper ends of the two half rings reaches the design gap, then lock the bolt between the upper connecting plate and the end block;Symmetrically install and tension the multiple tower ring cables close to the lower connecting plate, and unscrew the bolt between the lower connecting plate and the corresponding end block;Complete the installation and tension of the remaining tower beam cables and tower ring cables;After the completion of the bridge deck system construction, lock the bolt between the lower connecting plate and the end block.The application significantly improves the precision of high-altitude installation and the safety of construction process.
