Problems solved by technology

[0002] At present, freezing disasters are common in the construction of highways in Tibetan areas, Xinjiang and northern areas, especially the transition section from low altitude to high altitude. With the sharp increase in altitude, there is often frozen snow in winter and spring; Freezing damage often occurs, which affects the safety of the structure; and the road outside the tunnel is often covered with snow and freezes, which seriously affects road traffic safety

Abstract

The invention discloses a deicing and snow melting system utilizing terrestrial heat in a tunnel. The system comprises a heat pump unit, a heat supply pipe and heat exchange tubes, wherein the heat supply pipe and the heat exchange tubes are respectively communicated with the heat pump unit so as to form two circulating pipeline independent from each other; fluid in the heat supply pipe and the heat exchange tubes provides circulating power by virtue of the heat pump unit, and heat exchange is performed by virtue of the heat pump unit. According to the deicing and snow melting system utilizing terrestrial heat in the tunnel disclosed by the invention, rich geothermal resources in a high-temperature geothermal area can be utilized, and the terrestrial heat energy in the tunnel is transferred to the ground by virtue of the pipeline, so that the aims of actively melting snow and deicing are achieved. The snows and ice on the road surface in spring and winter can be eliminated, the road riding safety problem is improved, the asphalt pavement service quality is improved, the traffic accident rate and economic losses are reduced, the life and property safety of the masses can be protected, the service performance of the asphalt pavement can be maintained, the service life is prolonged, the environmental hazards caused by use of chlorine deicers are reduced, good economical benefits are achieved, and the renewable and sustainable energy, namely, the terrestrial heat energy is reasonably used.

Description

technical field [0001] The invention relates to a snow-melting and ice-melting system, in particular to a snow-melting and ice-melting system utilizing geothermal heat in a tunnel. Background technique [0002] At present, freezing disasters are common in the construction of highways in Tibetan areas, Xinjiang and northern areas, especially the transition section from low altitude to high altitude. With the sharp increase in altitude, there is often frozen snow in winter and spring; Freezing damage often occurs, which affects the safety of the structure; and the road outside the tunnel is often covered with snow and freezes, which seriously affects road traffic safety. [0003] Therefore, a snow melting and ice melting system is needed to solve the problem of tunnel freezing damage and reduce road traffic safety hazards. Contents of the invention [0004] In view of this, the object of the present invention is to provide a snow-melting and ice-melting system utilizing geo...
