Zusammenfassung:	The utility model discloses a cold region tunnel heat insulation water outlet structure with the advantages that the length is shorter, and the heat insulation requirement can be met. The cold region tunnel heat insulation water outlet structure comprises a tunnel water discharge pipe, a water outlet structure and a water discharge hole structure, wherein the water outlet structure comprises a water-pervious blind ditch layer, a piling layer and an outer heat insulation layer, the water-pervious blind ditch layer is arranged at an outlet of the tunnel water discharge pipe, the piling layer is arranged at the upper side of the water-pervious blind ditch layer, the water outlet structure also comprises a leveling layer and a heat insulation material layer, the leveling layer is arranged on the outer side surfaces of the water-pervious blind ditch layer and the piling layer in a covering way, the heat insulation material layer is arranged on the outer side surface of the leveling layer in a covering way, the outer side heat insulation layer is arranged on the outer side surface of the heat insulation material layer in a covering way, and the water discharge hole structure is arranged at the lower side of the water outlet structure and penetrates through the leveling layer, the heat insulation material layer and the outer side heat insulation layer so that the water-pervious blind ditch layer is communicated with the outside. Through the leveling layer and the heat insulation material layer, the lowest maintaining temperature of the heat insulation water outlet structure under the same conditions is higher, and the heat insulation requirement can still be met when the length is shorter.
