Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline lifting, and in particular relates to a construction method for integrally lifting integrated pipelines in a large space of a steel structure factory building. Background Art

[0002] With the rapid economic development and industrialization in my country, steel-structured factories, as a major form of modern industrial architecture, are increasingly being used. However, the large, elevated spaces of steel-structured factories also present challenges for the layout and management of integrated pipelines. How to comprehensively upgrade integrated pipelines within these large spaces and improve the efficiency and management of pipeline layout has become a pressing issue in the design and management of steel-structured factories in my country. Comprehensively upgrading integrated pipelines within these large spaces is an efficient, economical, and environmentally friendly method for pipeline installation, significantly improving space utilization, reducing installation costs, and enhancing work efficiency. First, comprehensively upgrading integrated pipelines within these large spaces improves space utilization. Traditional pipeline installation methods often require a significant amount of space, resulting in low space utilization. The comprehensive upgrading method, however, allows pipelines to be installed above the factory floor, saving significant space and increasing space utilization. Second, comprehensively upgrading integrated pipelines within these large spaces reduces installation costs. Traditional pipeline installation methods require numerous brackets, hangers, and other equipment, which not only increases installation costs but also takes up significant space. The integrated lifting method, however, reduces the use of these devices and lowers installation costs. Furthermore, the integrated lifting of pipelines within the large, high-ceiling steel structure plant can improve work efficiency. Traditional pipeline installation methods require multiple lifting and welding operations, which are not only time-consuming and labor-intensive but also prone to errors. The integrated lifting method, however, allows for the complete installation of pipelines in a single operation, improving work efficiency.

[0003] However, the pipeline will produce increased stress during the comprehensive lifting process, resulting in increased vibration frequency and increased installation risks. At the same time, the vibration will increase the noise of the pipeline during use. Summary of the Invention
