Ultrahigh-ground-temperature tunnel supporting structure

The invention provides an ultrahigh-ground-temperature tunnel supporting structure, and belongs to the technical field of tunnel supporting. A primary lining layer in a primary supporting structure isapplied to the surface of surrounding rock, a waterproof layer is applied to the primary lining layer, a heat exchange layer is arranged in the waterproof layer, and a steel pipe network is arrangedin the heat exchange layer; a heat insulation layer in a later supporting structure is applied to the waterproof layer, and a secondary lining layer is applied to the heat insulation layer; a heat energy recovery mechanism comprises a supporting assembly, a heat dissipation assembly and a recovery assembly; and a solar power generation mechanism is electrically connected with the heat energy recovery mechanism, a second mounting frame in the solar power generation mechanism is fixedly mounted on a mountain body provided with a tunnel, a solar cell panel is fixedly mounted on the second mounting frame, a solar controlle
