Abstract

The invention relates to the technical field of pavement ice melting, in particular to an ice melting system of a tunnel pavement. The ice melting system involves a geothermal heat exchange pipeline,a tunnel pavement pipeline, a heat pump system, a water inlet main pipe and a water outlet main pipe, wherein a water outlet of the geothermal heat exchange pipeline communicates with a water inlet ofthe tunnel pavement pipeline through the water outlet main pipe, and a water outlet of the tunnel pavement pipeline communicates with a water inlet of the geothermal heat exchange pipeline through the water inlet main pipe; and the geothermal heat exchange pipeline, the water outlet main pipe, the tunnel pavement pipeline and the water inlet main pipe sequentially communicate to form a first-stage circulation water channel, and the heat pump system exchanges heat with the water outlet main pipe. According to the ice melting system of the tunnel pavement, the heat obtaining of the geothermal heat exchange pipeline and the heat supply of the heat pump system are combined to melt accumulated snow or accumulated ice on the tunnel pavement together, so that the running safety of a vehicle in atunnel can be ensured; and a large amount of heat can be obtained by the geothermal heat exchange pipeline, so that the geothermal utilization rate is improved, and then the accumulated snow or the accumulated ice on the tunnel pavement is melted.

Description

technical field [0001] The invention relates to the technical field of road surface ice melting, in particular to an ice melting system for tunnel road surfaces. Background technique [0002] Roads in cold regions tend to accumulate snow and freeze in winter, especially dark ice forms at tunnel entrances and other road sections, which can easily induce traffic accidents and bring serious harm to traffic. The traditional method is to sprinkle snow-melting and ice-melting agents, which is costly, will cause corrosion to the road surface, and will also pollute the environment. The electric snow and ice melting system consumes a lot of energy, and most of the sunny weather also needs to be heated, wasting a lot of energy. High operating costs. [0003] In the existing road surface ice-melting devices, multiple heat pipes are used to transfer the underground temperature to the surface for snow melting, but this solution has many disadvantages, such as: the heat pipes are diffic...
