Cross construction structure of deep foundation pit of metro interchange station

The utility model discloses a cross construction structure of a deep foundation pit of a metro interchange station. An outer support of a node section foundation pit containment structure and an outer angle plate support of the node section foundation pit containment structure corresponding to the feeble position of the node section foundation pit containment structure are arranged in a standard section foundation pit; when crossly constructing the node section foundation pit and standard section foundation pit, the difference between the excavation elevations of the node section foundation pit and the standard section foundation pit is smaller than or equal to 5 meters. Through arranging the outer support and outer angle plate support of the node section foundation pit containment structure in the standard section foundation pit, the cross construction between the node section foundation pit and standard section foundation pit is realized, and the construction time and construction cost are greatly shortened.
