To costlessly carry out a stabilizing repair for preventing settlement of a road or the like formed with an embankment on a soft ground in a short time without any traffic regulation of the road or the like on the upper face, by propulsively inserting a hollow embedding material from the external face of a soil structure on the soft ground to embed the hollow material in the soil structure.
A jacking device 30 for insertion of a hollow embedding pipe is arranged at a side location of a slope face 21 at the embankment side of an approach road 20 of a bridge which has settled or is expected to settle, to propulsively insert a hollow embedding pipe 40 into the slope face 21 of the embankment by the jacking device 30 and embed the pipe in the embankment. Soil penetrated in the hollow embedded pipe 40 at the same time with the embedment of the pipe is discharged to the outside of the pipe 40 to empty the hollow embedding pipe 40. In this way, many hollow embedding pipes 40 are embedded in rows at every nearly equal distance and also vertically embedded in several stages at every distance on the slope face 21 of the embankment to stabilize the soil structure on the soft ground, in the repair work for lightening the weight of an approach road 20.
