The Design and Practice of Foundation Pit Support in the Early Stage of Building Translation Reconstruction
Due to its high social and economic benefits,the building overall translation underpinning technology is more and more widely used.The preliminary preparation engineering for building migration in complex environment directly affects the quality of engineering implementation,which is also the key and difficult point of building overall translation underpinning.Therefore,based on the foundation pit engineering in the early stage of a building translation reconstruction in Xiamen,this paper discusses the key and difficult problems in the design and practice of the deep and large foundation pit as the preliminary preparation engineering of building migration.By analyzing the engineering geological conditions of the foundation pit engineering in the early stage,the support forms for different areas are proposed,including soil nail wall,reinforced concrete row piles,etc.,and the construction process and precautions are described in detail,in order to provide some reference experience for the preparation work of the foundation pit engineering in the early stage of the subsequent building translation,and solve the conflict between the existing important buildings and the planning.
