The utility model discloses a small excavation gas dragging pipe formwork device which comprises a bottom plate, two vertical rods perpendicular to the bottom plate and a detection part arranged between the vertical rods, and a plurality of through holes are formed in the bottom plate in the two vertical rods. A vertical sliding groove is formed in the vertical rod in the vertical direction. The detection component comprises a fixed descending mechanism and a probing mechanism, the probing mechanism is limited in the two vertical rods by the fixed descending mechanism, and the lower end of the probing mechanism enters the stratum through the through hole under the downward driving of the fixed descending mechanism along the vertical sliding groove; when the lower end of the probing mechanism is close to the gas dragging pipe, descending is stopped, and the trend of the gas dragging pipe is determined. The device only needs to excavate an existing road structure and broken stones, the excavation range is small
