The phenomena caused by the freezing and thawing of seasonal frozen soil greatly affect the development of China's construction, transportation and other fields. The roadbed is an important part of the highway. The stability and strength of the roadbed directly affect the strength, flatness and stability of the road surface, and thus affect the quality of the entire road. Due to the frost heave of seasonal frozen soil, the thaw settlement of the soil forms mud pumping on the road, which seriously affects the highway operation safety.

However, in seasonal frozen soil areas, due to the particularity of the soil freeze-thaw cycle, the buried frost heave and thaw settlement sensors are prone to failure after long-term use, resulting in data distortion. Therefore, it is necessary to regularly inspect and maintain the buried sensors. Each time when maintaining the buried frost heave and thaw settlement sensors, it is necessary to dig out the sensors from the ground, and the maintenance cost is high. Utility Model Content
