Key Construction Technology of Deep Foundation Excavation Engineering in Complex Environment Region
Based on a deep foundation excavation project in an urban area with a complex environment,the combined forward and reverse construction method of a deep foundation excavation is adopted.The construction technology of component nodes,such as precise construction of a"single pile single column"lattice column,outsourcing vertical column construction and vertical reinforcement connection of multi-layer structural columns,etc.,is innovated.And a suspension support system for beam and plate construction,which is both environmentally friendly and economical,is developed to ensure the overall support effect of foundation excavation engineering.
