| Abstract: | At present, there is no uniform standard for ultra-deep foundation pit, which has many difficult points in design and construction. Once a problem occurs, serious economic loss and safety accident will be caused. Through an engineering example, high-pressure spraying for sealing and dewatering well are put forward for seepage control. It is recommended to take the in the design and construction of ultra-deep foundation pit, provide reference for the similar engineering. shortest construction time as management objective and the experiences and lessons are summarized toprovide reference for the similar engineering. |
