The reporter learned from China Railway Eleventh Bureau Group Co., Ltd., that on the 25th, the No. 2 bridge on the Guilin Outer Ring Expressway successfully completed swivel construction and successfully crossed the two main railway lines of the Xianggui Railway and the Hengliu Railway, laying a solid foundation for the completion and opening of the entire line to traffic as scheduled. Wufu Bridge No. 2 Bridge is a full-line control project of the Guilin Outer Ring Expressway. Its swivel section is 160 meters long, 32.2 meters wide, and has a rotating weight of 25,000 tons. In order to ensure the normal operation of the Xianggui and Hengliu railways, the construction team built the bridge parallel to the railway, and then made full use of the method of rotating the bridge during the “sunroof” time when trains were not running for the time being to rotate the construction. In the rotation operation, the builder uses an intelligent synchronous traction system and a multi-dimensional real-time monitoring system to monitor core parameters such as beam stress, displacement, speed, and traction force in real time, and dynamically adjust construction parameters to achieve “millimeter-level” accurate docking.
