Description

Technical Field

[0002] With the rise of my country's construction industry, some large-scale underground space structure designs emerge in an endless stream, most of which are underground multi-layer space structures. However, according to the geological conditions and the increase in depth, before the construction of the real underground space main structure, the design and construction of the preliminary temporary support system is also particularly important. However, in the final formation of the real underground space structure, the difficulty and disadvantages of the temporary support system in the process of demolition are also increasingly apparent. In the process of demolition, the demolition, division and erection and top support of the temporary support system before demolition are also particularly important. And often due to the huge body of the building itself, the obstacles to the demolition process are very obvious. The safety and stability work before demolition must be in place. In practice, the traditional top support using the pipe rack system as the support system for demolition is also pale and powerless, and there are safety hazards. A lot of manpower and material resources are required in the process of construction and erection, and the amount of material removal and pipe racking required is astonishing. The erection is cumbersome, which seriously affects the progress of the construction period. It needs to be erected one by one and then dismantled one by one, which seriously reduces the construction efficiency. Utility Model Content
