Construction Technology of Foundation Pit Support and Foundation Treatment for Muddy Sites
Based on a large-scale foundation pit supporting project in a municipal reclamation area,in order to reduce the project cost and optimize the foundation pit supporting scheme,based on the topography,hydrogeology and surrounding environment conditions of the construction project site,according to the requirements of environmental protection and reducing the impact on underground pipelines and nearby subway construction,the"internal support and occlusion pile"supporting scheme is adopted.Three concrete internal supports are set to share the water and soil pressure outside the deep foundation pit.At the same time,in order to meet the changes of foundation pit strata and the requirements of excavation depth,the whole foundation pit is divided into 13 sections,and support construction is carried out according to the construction requirements.Finally,the deformation characteristics of foundation pit supporting structure in silt site are discussed by numerical simulation,and the key points of foundation pit supporting are clarified.
