Project name: The first part integrated buried pier of the hong kong-zhuhai-macao bridge
Brief introduction: On June 20th, 2013, at 12:00 am, the first integrated buried pier of the hong kong-zhuhai-macao bridge was successfully installed, marking the formal entry into the "maritime assembly" stage of the bridge project of the hongkong-zhuhai-macao bridge.
In order to make the pier more secure, stable and accurate to the base, we put the strain and steel strain gauge on the sling to monitor the force of the four cables when lifting. The installation of the pier is divided into lifting gear lifting, pier lifting, pier alignment, precision adjustment, lifting gear and removing.
After the whole-process monitoring, data comparison and analysis, the final installation of the pier was successful, and the verticality error was reached the design requirements between 0.014 and 0. 019.laying a foundation to ensure the future construction of the hong kong-zhuhai-macao bridge and the overall stability of the bridge.
