Technical Field

The utility model relates to a highway protection field especially relates to a prevent subsiding protection mechanism based on highway subgrade.

Background

The foundation settlement refers to the foundation surface subsidence caused by compaction of a foundation soil layer under the action of additional stress. Excessive settlement, especially uneven settlement, can cause the building to tilt and crack so that the building cannot be used normally. The existing foundation settlement prediction method is limited by the fact that the assumed conditions are not in accordance with the actual conditions, and the obtained settlement prediction result is often different from the actually measured settlement value. Research on the foundation settlement prediction method is in need of further development.

Chinese patent "CN 206607465U" a highway subgrade anti-settling device, the device has improved the whole compressive property of subgrade, reduced the probability that the subgrade pile appears breaking and the subgrade subsides, prolonged the life of subgrade pile, thereby prolonged the life of highway subgrade anti-settling device, but the device mainly mentions the whole protector of highway, but with regard to subgrade subsidence, the foundation settlement problem of bridgehead subgrade junction is more showing, because the construction material of road and bridge is different, cause the subside easily between highway and the bridge foundation, we have proposed a protection mechanism based on highway subgrade anti-settling for this reason.
