[0026] Working principle: Highway roadbed is the foundation layer for supporting the road surface. When building a highway, it is necessary to carry out roadbed engineering first, that is, through excavation, filling and compaction, a roadbed of a certain thickness is constructed to support and distribute the traffic load, prevent the road surface from deforming and settling, and ensure the safety and durability of the highway. After the existing roadbed is paved, if the inner side collapses and causes the roadbed to tilt, it will be impossible to repair and adjust the roadbed in time, resulting in the road surface tilting and being unusable. In order to solve this problem, an adjustment mechanism and a filling mechanism are set up, and the cone 12 is inserted into the inner side of the rammed earth layer, and gravel is filled between the cone 1 and the chassis 8. At this time, the seat 22 can be cooperated to rotate the rotating rod 23, so that it pushes the piston 24 to rotate while sliding downward on the inside of the cylinder 21, and the foaming agent inside is discharged from the output hole 25, thereby filling the gaps in the gravel, so that it can support the roadbed structure. The rotating rod 23 pushes the lifting platform 14 to descend inside the cone cylinder 12. At this time, with the cooperation of the connecting seat 15, the connecting rod 17 and the straight rod 20 rotate around the connecting pin, thereby supporting the inside of the rammed earth layer and fixing the position of the cone cylinder 12, thereby preventing the cone cylinder 12 from falling off under force, making the roadbed structure more solid. After the roadbed is paved, if a collapse occurs, the hexagonal stud 5 at the depression is selected to rotate, so that it drives the threaded rod 4 to rotate, and through the cooperation of the thread groove 7, the threaded cylinder 6 is pushed to slide inside the limiting hole 10. At this time, the support plate 11 extends downward from the bottom side of the limiting hole 10 and presses on the rammed earth layer. At this time, the threaded rod 4 extends, thereby supporting the support plate 2 at the depression, so that the roadbed structure is restored to a horizontal level, thereby ensuring that when the roadbed collapses and tilts, it can be repaired in time. Finally, the concrete pavement is paved on the top side of the round table 1 and the reinforcing net 3, completing the construction of the roadbed structure, solving the problem that the existing roadbed cannot continue to repair the collapsed part.
