Description

Technical Field

[0001] The invention relates to the technical field of highway construction, and in particular to a highway subgrade reinforcement device. Background Art

[0002] The roadbed is the foundation of the track or road surface. It is a geotechnical structure formed by excavation or filling. Due to geographical location and environmental factors, the roadbed of the highway will have different problems, such as silty soil, collapsible loess, expansive soil and frozen soil. Therefore, the roadbed needs to be reinforced to improve the roadbed and enhance its stability.

[0003] At present, for the reinforcement of highway subgrade, it is necessary to first turn up the road surface to a certain depth, and then spray a proper amount of soil solidifier evenly on the turned-up soil to mix them. When the soil solidifier is evenly mixed with the turned-up soil, it is flattened to obtain the reinforced roadbed. However, the sequential operation process of turning up the soil, spraying the soil solidifier, and then mixing them is relatively cumbersome, and different equipment needs to be used in sequence, which is inefficient and costly. For this reason, the present application proposes a highway subgrade reinforcement device. Summary of the invention
