In the seasonal frozen soil area, the negative temperature in winter will cause the surface temperature to drop, forming a temperature gradient with the underground temperature. Under the induction of temperature gradient, the film water will migrate from the high temperature to the low temperature, and will be separated into ice in the soil, causing frost heaving. The heat stick technology is used to protect the frozen soil foundation in the prior art.

[0003] The heat stick technology is widely used in the railway, highway, bridge, culvert, tunnel, communication line tower, water conservancy project and port engineering in the permafrost area. In these foundation engineering, the heat stick is used to cool the foundation, prevent the foundation frost heaving and thawing deformation, and ensure the stability of the frozen soil foundation. The new energy resources are rich in the western region of China.
