Embodiment
[0043]Permafrost is a special rock and soil with a temperature at or below 0°C and containing ice. It is very sensitive to temperature changes. Climate warming and engineering construction will cause temperature rise and degradation of permafrost, which will affect the stability of the upper road. The difference in the absorption of solar radiation by the slopes on both sides of the subgrade (also known as yin and yang slopes) will further aggravate the disease of the frozen soil subgrade, induce uneven deformation of the subgrade, longitudinal cracking, etc., and directly affect the service function of the road. The heat pipe 1000 is the active cooling technology with the most obvious cooling effect in permafrost subgrades, and has been widely used in the stability maintenance of permafrost subgrades in some major projects. However, the inventors found that the heat pipe 1000 in the frozen soil roadbed is mainly installed vertically or obliquely on both sides of the roadbed. ...
