Discussion of Different Hanging Shotcrete Applications Between Pile Foundation Pits

Three protective structure practice between retaining piles about building construction excavation structure are described on page 30,31 in the national Building Standard Design Atlas 11SG814.Several application examples are introduced to compare and analyze the problem of which is the best way.It is concluded that retaining structure design and construction should be selected according to the actual needs both economically feasible and economically reasonable approach,so that the cost savings and good yields effects will be realized to ensure the construction quality and safety conditions.
