Description of the Related Art Conventionally, a synthetic resin pipe is buried in a road surface such as a road or a parking lot, a heat medium is passed through the synthetic resin pipe, and the heat emitted from the heat medium heats the road surface to cause snow accumulation on the road surface. A road surface heating method for preventing freezing is known. And since the road surface heating pipe used in this road surface heating method is a synthetic resin pipe, it is difficult for heat to be transferred, and therefore, the heat transfer resistance from the heat medium passing through the pipe to the snow on the road surface is large, There was a problem that the heat flux required for snow melting could not be obtained unless the temperature of the heating medium was raised. As one means to solve this, by forming the road surface heating pipe with a synthetic resin pipe with a metal wire embedded in the peripheral wall, the heat transfer resistance from the hot water flowing in the pipe to the snow on the road surface is reduced. Therefore, the hot water pipe type road surface snow melting structure that can obtain the heat flux necessary for snow melting even if the hot water temperature is low,
Is disclosed in JP-A-3-42808.
