2. Description of the Related Art Heretofore, this type is as follows. Conventional snow melting road methods include two methods: a snow melting method for artificial energy resources and a snow melting method for natural energy resources. The artificial energy resources snow melting method is an easy-to-understand one that has been developed and developed sequentially since ancient times, such as electrothermal snow melting, gas, and oil fuel snow melting. Currently, snow melting methods for natural energy resources include a watering method using groundwater and a waterless method.

[0003]

The above-mentioned prior art has the following problems. Artificial energy resources snow melting methods often require human resources. The water spraying method, which is a natural energy resource snow melting method, calls for the depletion of groundwater, and the non-sprinkling method generally makes it impossible to freeze for one season due to freezing of the snow melting medium liquid, and also points out the difficulty of management corresponding to the stoppage of power and oil engines. Have been. In other words, in the conventional snow melting technology, it is difficult to maintain and manage failure measures and the like in general household technology, so that the cost of electricity and oil is increased, and there is a concern that various pollution may sometimes occur. . Moreover, although the conventional technology is already a mature technology and has a high degree of perfection, it is difficult to solve pollution, etc., and new problems are increasing.

The present invention has been made in view of such problems of the prior art, and has as its object to provide an object which can achieve the following objectives. 1. The anthropogenic energy snow melting method utilizes the earth's preserving geothermal heat, which does not require the necessary electric heat, gas, or oil combustion heat. 2. The natural energy resource snow melting method generally uses a large amount of water as a snow melting medium liquid, but there is a need for development capable of operating snow melting with a certain appropriate amount of the snow melting medium liquid. 3. A configuration that requires as little human intervention as possible and has no breakdowns. 4. The operation and management of the snow melting facility can be continuously managed and maintained even with the technical knowledge of domestic people, and at the same time, even if there is a breakdown, it can be easily modified and repaired. 5. Eliminate the need for urban facilities such as sewage facilities. 6. Wherever snow melting is required, the required snow melting facilities can be created. 7. There should be no environmental pollution such as groundwater pollution, groundwater depletion, air pollution, and noise. 8. The operation and maintenance costs due to the operation of snowmelt are cheap and can be managed by anyone at the same time. 9. For example, snow can be reliably melted even during heavy snowfall of 25 cm or more day and night. 10. The left and right single heat storage tanks with reduction vertical holes that have water passages for infiltrating rainwater, sprinkling water, and snowmelt that accumulate on the snowmelt road surface and reducing them underground are connected to the connection of the snowmelt medium water convection circulation inlet and outlet. The convection circulation of the snow-melting medium water is alternately performed by the reverse exchange, and the snow-melting operation starts at the crossing. Note that there is no accumulated water on the snow melting disk due to the reduced vertical holes, and the snow melting road is free from water contamination. 11. Frequent use of heavy vehicles due to the synergistic effect of the convection circulating snow-melting device, as well as additional support columns, by mounting the appropriate number of vertical shaft holes for underground reduction of rainwater, sprinkling water, snow-melting water, etc. The convection circulating snow melting device is robust enough to withstand traffic and suitable for heavy vehicle traffic.

Thereby, the above-mentioned aims 1 and 2 can be achieved. 2. When the snow melting operation is performed by the present invention, a convection circulation naturally occurs due to a temperature difference between the cooling snow melting reducing liquid cooled and radiated on the snow melting road surface and the snow melting geothermal liquid collecting the geothermal heat from the geothermal collecting well.

3. Since the thing of this application is the use of only a certain amount of snow melting medium water, any place where snow melting is planned,
Further, even if there is no groundwater used for the snow-melting liquid in the underground formation at the place where snow melting is planned, the terrestrial geothermal energy is always preserved, so that a convection circulating snow melting apparatus can be provided. In addition, it is possible to eliminate the necessity of an urban-type auxiliary facility such as a sewerage facility for treating used snowmelt water, such as a sprinkling snowmelt apparatus using a large amount of groundwater. Thereby, the aim 5,6
Can be achieved. 4. The system is configured so that snow melting is performed by convective circulation operation of snow melting medium water, so there is no pumping of snow melting geothermal liquid and underground reduction of snow melting cooling and reducing liquid, so there is no groundwater shortage, land subsidence, groundwater contamination, and Since it does not melt snow by electric heating, gas and oil burning, it does not cause environmental pollution such as air pollution and noise, and its structure is simple, simple, and robust. It can be managed with common sense technology. As a result, the above objectives 7 and 8 can be achieved. 5. Since the first and second underwater heaters are provided, they can be operated only during heavy snowfall to warm the snowmelting medium water W and increase the snowmelting ability. Thereby, the aim 9 described above can be achieved. 6. If a group of reduction vertical holes is installed at an appropriate position of a single heat storage tank and a snowmelt case connected to the tank, rainwater, sprinkling water, and snowmelt water staying on the snowmelt flow down the group of reduction vertical holes and are returned underground. Thereby, the aim 10 described above can be achieved. 7.

Thereby, the aim 11 described above can be achieved.

Snow melting equipment can be installed at the desired location. 4. As mentioned above, groundwater is not used,
There is no groundwater contamination, and there is no need for urban facilities such as sewers and drains to treat used snowmelt medium. Since power operation is not required, so-called energy saving is achieved, and there is no pollution caused by fuel combustion and noise generation, and it is very economical. In addition, since it is a snow melting device using the convection circulation of natural science phenomena,
It is not technically complicated, has a configuration that can be understood by ordinary household technology, has a simple structure, is robust, and has no failure. By any chance,
Even if there is a breakdown, it is easy to repair, and it can be used as a useful snow melting device, as it can be maintained and managed with common household common sense technology and at the same time it is cheaper. 5.
