| Abstract: | In light of the existing problems in the development of soil-cement mixing piles, T-shaped bidirectional soil-cement deep mixing columns and their construction technology are introduced. Construction quality test results show that the quality of T-shaped bidirectional soil-cement deep mixing columns are better than conventional soil-cement mixing piles. Compared to conventional cement mixing piles composite foundation, the bearing capacity of the pile foundation and composite have improved greatly. Through the observation of the analysis of test site result, the engineering properties and economic benefits of the method that T-shaped bidirectional soil-cement deep mixing columns reinforces soft ground superior are demonstrated. |
