| Abstract:The pit type static pressure steel tube pile is a technical method to solve soft soil foundation deformation of existing buildings due to subsidence. According to the foundation deformation and geological conditions of the inspection building of Beihuaguan Aluminum Chemical Company LTD. in Shanxi Province, a design was proposed for reinforcement by using pit type static pressure steel pipe piles with the construction schemes, construction processes and notes described. The problems encountered in the construction process are summarized with the monitoring data after construction analyzed. The results show that pit type static pressure steel tube piles are effective for soft foundation reinforcement and can successfully solve cracking of the foundation due to settlement of the soft soil layer. |
