The invention belongs to the technical field of tunnel tunneling construction and particularly relates to a construction method of a pipe shed work room of a soil layer tunnel. Modeling is conducted through a building information modeling (BIM) technology, and pipe shed steel pipe construction is small in deviation and high in precision. Pipe shed advance supporting is adopted, the pre-supportingcycle frequency is greatly decreased, a large amount of procedure connection and preparation time is saved, the construction efficiency is remarkably improved, the reasonable supporting distance and excavation step pitch are determined, and the ground subsidence amount is small. The difficult problems that the urban shallow-buried tunnel with the soft soil layer geological condition is low in construction speed and high in construction cost are solved, and the economic and social benefits are remarkable.
