Introducing the use of synchronous hydraulic control system technology to achieve the overall lifting and sliding installation process of large tonnage steel structure modules, discussing the principle of hydraulic lifting control, and focusing on the key design methods and construction points of the installation process. Engineering practice has shown that the successful use of hydraulic synchronous control system technology for the overall lifting and sliding of large tonnage steel structure modules in one go has improved construction progress and engineering quality, achieving significant technical and economic benefits. Summarizing the aspects that need to be improved and paid attention to in the construction practice of the installation process, providing a reference for similar large tonnage overall installation projects.
