Provide is a method for real-time deviation monitoring of miniature pipe-roofing jacking pipes of spiral soil-discharging. The method includes: welding a measurement auxiliary pipe to an outer wall of a pipe-roofing steel pipe, providing a laser pen inside a front end of the measurement auxiliary pipe, and the laser pen emits a beam propagating from the front end to a rear end of the measurement auxiliary pipe. After installation, a male lock buckle and a female lock buckle are symmetrically welded onto the pipe-roofing steel pipe, and form an integrated structure with the pipe-roofing steel pipe. A measurement plate is fixedly mounted on a housing of a pipe-roofing drilling machine. During jacking, a change of a position of the beam on the measurement plate is observed to determine a deviation of a drill bit of the pipe-roofing drilling machine and the pipe-roofing steel pipe in real-time.
