Refrigeration structure of power transmission tower foundation in permafrost region
The invention relates to a refrigeration structure of a power transmission tower foundation in a permafrost region. The refrigeration structure comprises a natural earth's surface, a tower foundation, a porous medium layer and geotechnical cloth. In a dug natural earth's surface pit, the porous medium layer is laid around the cast tower foundation; the geotechnical cloth is laid at the upper part of the porous medium layer; and the natural earth's surface is embedded above the geotechnical cloth. The refrigeration structure uses the porous medium layer for lowering the soil mass temperature to stop the water migration and the water discharge so as to prevent such damages as soil mass frost heaving and tower foundation thaw collapse and frost heaving; and in addition, as the porous medium layer is embedded around the tower foundation below the natural earth's surface, the thermal influence effect caused by the engineering disturbance can be quickly eliminated.
