The main steel structure of CDQ is a fully bolted frame structure that bears dynamic loads, and its construction requirements are much higher than that of conventional steel frame structures. Therefore, targeted process measures must be taken to achieve the construction goals of the main steel structure. Based on the construction characteristics of the main steel structure, the pre-construction planning, factory production, streamlined construction, etc. are discussed in this article, and the technological measures to ensure the accuracy of production and installation, improve construction efficiency, optimize construction costs, and ensure operational safety are summarized. Engineering practice shows that the construction goals of the main steel structure can be achieved through coordinated manufacturing and installation of technological means, laying the foundation for the safe and stable operation of the CDQ system.
