Description

  The present invention relates to a snow melting device that melts snow using collected geothermal heat.

  Conventionally, a snowmelting device generally uses a watering method of pumping up groundwater and spraying it, but this method is not suitable for an area with little groundwater because there is concern about ground subsidence due to the depletion of groundwater.

  Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 11-350411, there has been proposed a snow melting device (hereinafter, a conventional example) that melts snow by collecting geothermal heat.

  In this conventional example, as shown in FIG. 6, a heat collecting portion 32A of a long heat transfer body 32 (heat pipe) is disposed in a drilling hole 31 formed in the ground, and the heat collected by this heat collecting portion 32A. The heat dissipating part 32B that dissipates heat is disposed in the snow melting part 33 (pavement material) provided on the ground surface. The excavation hole 31 is filled with concrete or quartz sand as the heat transfer member 34 in order to satisfactorily transmit geothermal heat from the ground to the heat collecting section 32A.

  Therefore, if it is a prior art example, groundwater will not be consumed, but it can apply also to the area where ground subsidence due to the depletion of groundwater is concerned, or the area where there is little groundwater.

  However, the conventional example has a problem in repairing the buried object 20 such as a gas pipe or a water pipe buried under the snow melting portion 33 due to its structure.

Specifically, for example, when repairing the buried pipe 20 buried under the snow melting portion 33 as shown in FIGS. 6 and 7 (blocking operation of the leakage hole 20a), a pavement material constituting the snow melting portion 33 is used. breaking operation for removing is required, at the time broke paving material, of course since the heat radiating portion 32B of the heat pipe 32 is also damaged, adoption of the heat pipe 32 by removing the heat transfer member 34 that fills the wellbore 31 The work to remove the hot part 32A must also be carried out, so that the entire construction becomes large, and when reconstructing the conventional example, a pavement material constituting the snow melting part 33 is placed. There is a problem that it is not economical, for example, a new heat pipe 32 must be prepared.

  The present invention solves the above problems and provides an epoch-making snow melting device that exhibits unprecedented effects.

  The gist of the present invention will be described with reference to the accompanying drawings.
