Abstract
In order to explore how to improve the installation process of large submerged caissons,this article describes a method used in the starting project of Longqi Bay Port Area in Jinzhou Port In the aspects of work process and installation quality of the caissons,detail accounts are given for he entire process from the design to the installation of the caissons,including summaries of the problems found during construction and scheme optimization.The innovation of this article lies in the use of steel structure fences combined with steel templates to elevate the caisson,achieving the installation of steel templates and fences in stages,effectively reducing the lifting weight.Meanwhile,the enclosure can be reused,further reducing construction costs.This process not only improves construction efficiency,but also provides strong guarantees for the stability and quality of caisson installation.关键词
