Study on the preservation of"one body,two generations and three types"historical wall and the connection between old and new prefabricated structures in the whole block
In order to protect the important historical interface of the city,there is an increasing demand for new internal structures to preserve the feature wall along the street,and how to realize the connection between the temporary support of the wall and the old and new structures has become a difficult problem to be broken through.Based on the research on the method of retaining feature wall and connecting old and new structures of a whole road section,the construction methods of joint replacement of deep and shallow foundation,temporary support transformation of steel structure,cast-in-place combined with prefabricated frame are put forward to realize the"one body,two generations and three types"feature wall preservation and structural renewal,which can provide relevant experience for the implementation of similar historical feature preservation projects in the later period.
