| Abstract: | The application of bored secant piles in deep excavation pits is gradually used widely. Combining the case of excavation construction of Mozhou Road Station in Nanjin metro line No.3, this paper introduces the construction technique of bored secant pile, and analysis the influence of super retarded concrete quality to the construction. At last, this paper concludes the common accidents in such construction process and the relevant treatment measures. |
