The Application of Full Reverse Construction Technology for One Column and One Pile in High-rise Buildings in Soft Soil Areas
This article mainly explores the application of one column,one pile full reverse construction technol ogy in a high-rise building in soft soil areas.The geological survey results indicate that the soft soil in the construc tion area is widely distributed and the groundwater level is high.Before the construction of steel pipe concrete piles,a dewatering well is used for dewatering.Then,the pile holes are excavated and after the quality inspection of the holes is passed,steel cages are placed and concrete is poured.Embed the steel column into the steel pipe concrete pile,and use the positioning shoe at the bottom of the column to fine tune the position and verticality of the steel column,ensuring accurate position and qualified verticality.In addition to properly treating the nodes between steel columns and reinforced concrete piles,the ring plate welding process is also used to reinforce the steel columns and beam slabs in the full reverse construction,ensuring the stability of the building foundation and providing experi ence and reference for the full reverse construction of one column and one pile.
