Slub lifting road
Roadway| Toll Road|
The work was carried out with constant laser monitoring of the lifting of the structures. The effectiveness of the work was established by the fact that the subsided structures were lifted to the design level. Maximum lifting of structures in the most subsided places.
Leveling and stabilizing the ring road
3 days
TECHNOLOGY APPLIED
The re-leveling structures involves the injection of a special expanding compound through small-diameter holes under the pavement structure. Expanding geopolymer injected between the soil and the structure gives the expansion coefficient by 20 to 1, capable of re-leveling the coating. In the process of injection, it is distributed under the road surface with simultaneous compaction of the week areas.
OUTCOME
The work was carried out under the constant laser monitoring of the lifting of the structures. The effectiveness of the foundation of the foundation was established by the actual lifting of the sagging structures to the design level. The maximum lift of structures in the most subsided places was 60 mm. The work time is 3 working days.
