If the track is installed on the viaduct (3), it is difficult to exclude lightning from the viaduct (3) due to the side walls (3a) of the viaduct.
The electrostatic groove (7) is parallel to the elevated track (4) on the viaduct floor (3b).
), the excluded N(8) is deposited and stored in this monolithic groove (7), and this M(8) is connected to a heat pipe (9).
) is melted by the heat transport effect. In other words, when the temperature on the other side (9b) of the heat pipe (9) is lower than the temperature on one side (9&) of the heat pipe (9), heat transport occurs.For example, when the electrostatic groove (7) The temperature inside is about 0℃. On the other hand, the temperature during soil destruction (2) is about 13 to 15 degrees Celsius on average at a depth of about 10 meters underground, even in winter. The heat in this soil (2) causes heat pipes (9) to
) is heated, and the working fluid in the heat pipe (9) is vaporized and takes away the amount of heat in the soil (2) as latent heat of vaporization and passes through the heat pipe (9).
) to the other side (9b).

。The vapor of the working fluid that has moved to the other side (9b) of the heat pipe (9) is condensed and liquefied because the temperature on the electrostatic groove (7) side is lower than that on the soil (2) side, and is transferred to the electrostatic groove (7) side. releases latent heat of condensation. The liquefied working fluid flows along the inner wall surface of the heat pipe (9) and returns to one end (9a) of the heat pipe (9). By naturally repeating the above motion, the amount of heat held by the soil (2) is transported to the electrostatic groove (7) side, heating the inside of the electrostatic groove (7) to 0°C or higher. is possible,
The M (8) deposited in the electrostatic groove (7) is melted.

ないという課題もある。[Problem to be Solved by the Invention J] However, in the conventional device described above, the soil (2) is used as a heat source, so if the temperature of the heat source is low and the amount of snow accumulated in the storage groove (7) is large, the heat source is insufficient. Snow melting effect cannot be achieved. In addition, if the period of thawing treatment continues, soil (2
) is consumed in the melting process, so soil (2)
The problem is that the snow melting effect gradually decreases as the temperature in the area gradually decreases. Also, what (9a) is on one side of the heat pipe (9)?
) is buried in soil (2) to a depth of about 10 holes, making the burying work extremely troublesome. Further, the other side (9b) of the heat pipe (9) is provided with an electrostatic groove (7).
) Since the snow is buried in the concrete at the bottom of the bottom, the burying work is very troublesome, and the melting process for the snow in the neck groove (7) is carried out from the other side (9b) of the heat pipe (9) to the concrete. This resulted in poor heat transfer efficiency and poor snow melting performance. As a result, there is a problem that load response is poor and snow melting performance cannot be promptly demonstrated when necessary.
