RESEARCH ON CONSTRUCTION TECHNOLOGY OF DEEP FOUNDATION PIT SUPPORT STRUCTURE WITH PERMANENT PRESENCE
The impact on the surrounding environment and the safety of foundation pit support in the construction process should be considered when the support project is replaced.Because there are many crosses between the construction area and the inner support area of the project basement,the corresponding inner support cannot be removed at the end of the construction due to the interference of the progress of adjacent zones,which affects the flow construction of the basement structure and prolongates the construction period.Taking a project in Bao'an District as an example,by setting a cantilever support structure,the non-construction area is supported in advance,which solves the problem that the internal support cannot be removed due to the different progress of the zoning,and there is no need to remove it later,achieving the effect of combining permanent presence.
