Abstract: For Taiyuan Redstar projects of underground structure by surrounding foundation pit top-down construction method, the “vertical stratification, horizontal section excavation”, a vertical structure in reinforcing bars in the construction process, structure type steel column inverted construction technology, top-down hierarchical, level segmentation step precipitation and other key technology not only can guarantee quality and safety of the project, but also can get good economic benefit and social benefit, which can provide reference for similar projects in the northern region.
Keywords: foundation pit; reverse method; step precipitation; section of a type of insert; insert method
