The invention discloses an underground engineering tunneling construction method and an underground station. The underground engineering tunneling construction method includes the steps: longitudinally jacking a plurality of uniformly arranged and mutually engaged steel pipes with wing plates welded on the peripheries along the top and the peripheries of two sides of an underground engineering structure in a working pit on the outer side of an underground engineering; timely excavating soil in the steep pipes and within the range of the wing plates of the adjacent steel pipes in the jacking process and transversely connecting the adjacent steel pipes by connectors; closing two ends of each steel pipe and two ends of the range of the wing plates of the adjacent steel pipes, and pouring concrete into the steel pipes and the range of the wing plates of the adjacent steel pipes to form an integrally stressed siding wall by the mutually engaged steel pipes; excavating soil corresponding to beams and columns in the main underground engineering structure step by step and constructing a beam and column structure of the main structure after excavating the soil; and constructing siding wall structures of a soil structure while excavating the soil. By the construction method, ground settlement can be effectively controlled, and the construction process is high in safety and mechanization degree.
