The invention discloses a super-large pipe shed construction method, and relates to the technical field of foundation reinforcement under complex geological conditions such as shallow underground excavation and with special reinforcement requirements. The method comprises the following steps: 1, excavating; 2, drilling; 3, performing steel pipe jacking; 4, wiring; 5, mounting an injection pipe; 6, grouting; 7, repeating the steps 2 to 6 until the design section is fully spread; 8, injecting slurry through a reserved grouting pipe to form a continuous structure at a to-be-reinforced region and finishing pipe shed construction when the slurry reaches set strength in 24 hours. Under the condition that normal construction of the lower part structure is guaranteed, a grouting hole is reserved and the grouting pressure is tracked and adjusted from time to time according to the feedback information monitored on site so as to prevent and resist settlement influence caused by lower part construction without producing abnormal influence to the existing ground surface structure or affecting normal use function.
