The invention relates to the technical field of gas pipeline first-aid repair, in particular to a drainage device for gas pipeline first-aid repair and a using method, and the drainage device comprises a gas pipeline buried underground and a dug first-aid repair groove. According to the drainage device for gas pipeline first-aid repair and the using method, the drainage rods are flexibly connected in parallel through the beam plates and the lantern rings, all the drainage rods are inserted into the first-aid repair groove and laid along the groove wall of the first-aid repair groove, after all the drainage rods are attached to the groove wall of the first-aid repair groove, the rotating ring is loosened, and the torsion spring pushes the rotating ring to return and move downwards; the conical openings on the inner sides of the drainage rods extrude the elastic teeth to be bent inwards and locked in the annular grooves, so that the drainage rods are locked through the lantern rings and the beam plates, the gro
