Description

Technical Field

[0001] The utility model relates to the technical field of highway roadbed anti-settling, in particular to a highway roadbed anti-settling device. Background Art

[0002] Highways refer to public roads between cities, between urban and rural areas, and between villages that are approved by the transportation authorities and can be used by cars. The roadbed is the foundation of the road. The quality of the roadbed during construction will affect the quality of the upper base and surface layer. If the roadbed is subjected to a large amount of load or its own geological conditions and settles, it will cause the upper base to shift and the surface layer to crack. Therefore, when dealing with the roadbed for important traffic, anti-settling devices can be used to improve the stability of the roadbed.

[0003] Most of the existing highway roadbed anti-settling devices use piling to improve the compactness of the soil in the roadbed to prevent the soil from flowing. However, the pile foundation is generally circular and can only remain stable through the friction between the pile wall and the soil after being driven in. The pile is prone to sinking after being loaded for a long time, thereby affecting the reinforcement effect of the roadbed and reducing the practicability of the device. Therefore, a highway roadbed anti-settling device is proposed to address the above problems. Utility Model Content
