The invention the tunnel inlet and outlet bouillon snow melting relates to a facility, is installed on a multiple formed in a longitudinal direction on the side lower portion of the tunnel so as to induce discharging the underground water flowing to the side along the upper surface of the tunnel, the heat absorbing tube for antifreeze flow from therein; Is buried in the lower portion of the inlet and outlet tunnels, it said heat pipe heat absorbing tube is in communication with said antifreeze fluid from the inside; And wherein the anti-freeze the heat absorbing tube and the pump unit that provides power to flow to the interior of the heat pipe; absorb heat from the ground water, including the anti-freeze in multiples wherein while the flow to the inside of the heat absorbing tube, and the while flowing the inside of the heat pipe is provided to discharge heat to the inlet and outlet portions.
By, according to the present invention, the anti-freeze is provided with a heat absorbing tube and the heat pipe to flow along the upper surface of the tunnel to absorb ground water column of a multiple for discharging induce ground water flowing through the side portion to release the inlet and outlet portion of the tunnel, a multiple and the heat of underground water can be used effectively used to remove the inlet and outlet parts of the snow or ice, also remove snow geothermal internal road lower by being anti-freeze auxiliary heat absorbing tube is provided to absorb the geothermal internal road lower portion of the tunnel additionally as well as to be used in, is provided for receiving the buffer Joe antifreeze that is heated by the heating element can be supplied stably to the column inlet and outlet section, even if a large amount of heat required for snow removal.
