Abstract

PURPOSE:To improve snow removing efficiency by setting a pumping-up pipe and a water returning pipe provided with pumps, vertically in two wells, to communicate the respective pipes with a solar heat collecting device and a snow-removing section radiating pipe, and by feeding the warmed water of a one-side well to the radiating pipe at the time of removing snow, to return cool water to the other side well. CONSTITUTION:Two wells 2a, 2b for storing underground water are excavated, and a pumping-up pipe 4a-provided with a pump 9a, and a pumping-up pipe 4b provided with a pump 9b, and a water returning pipe 11 are vertically set. Besides, the pumping-up pipes 4a, 4b, and the water returning pipe 11 are communicated with a solar heat collecting device (c) and a snow removing section (d), via changeover valves 7, 8, 10a, 10b, 14, 15. Then, in a summer time or the like, the water of the one-side well 2a is kept to be heated with solar heat, and at the time of removing snow, through no solar heat collecting device (c), warmed water is fed to the snow removing section (d), and the snow is removed, and cooling water is returned to the other-side well 2b. Besides, the snow removing section (d) is also served as a section for the preliminary heating of the solar heat collecting device (c) at the time of a fine weather. As a result, the snow can be efficiently removed.

2. Description of the Related Art Conventionally, a pipe installed on a road surface or a roof is used as a heat collector to obtain hot water in summer, and in winter, ground water or heating pumped from a deep well into the pipe is used. Attempts were made to use it to prevent freezing and to remove snow on the road through warm water.

However, these methods have some problems.

What to do when heat cannot be collected using the road surface or the roof due to location conditions or the like.

What to do when there is no pressurized aquifer having a heat retaining effect in the deep underground (40 to 200 m).

In some areas where ground subsidence has occurred, there are areas where the collection of groundwater in deep underground (for example, 20 m or less) is restricted.

In order to solve the above problems, the present invention requires a new idea, and the solar heat in summer is retained in and around the well by using a pavement or a dedicated solar heat collector installed at an appropriate place. The present invention has been completed in which heat is stored in a water layer and the stored groundwater in the well is used for effective snow melting during snowfall or freezing in winter.

In this case, a strainer 16 is provided on the peripheral wall of the well 2 to store the heat so that the surrounding groundwater 1a and 1b can also flow, and the well 2a is stored in order to secure this heat-stored groundwater 1 '.
A water shield wall 17 such as a grout is formed in the vicinity of the heat storage groundwater 1'to surround and protect the heat storage groundwater 1 ', and at the same time, does not affect the heat of other buried objects.

A pumping pipe 4a is suspended in the well 2a.

Two wells 2a and 2b that can store groundwater 1a and 1b are drilled.

A pumping pipe 4a is suspended in the well 2a.

The outlet end of the pumping pipe 4a is connected to the hot water outlet pipe 5 of the solar heat collecting apparatus c so as to communicate therewith.

Valves 7 and 8 are provided on both sides of the connection point 6.

A pumping pump 9a is provided on the pumping pipe 4a.

A return water pipe 11 provided with a valve 10a at the outlet of the pumping pipe 4a is vertically installed in the well 2a.

[0035]

Since the present invention is constructed as described above, the groundwater pumped from one well is collected by the solar heat collecting device in the summer to store the heat in the other well, which is stored in the winter. High-temperature groundwater is sent to the snow-melting section, for example, road snow-melting is performed and water is returned to the other well again, so warm groundwater can be obtained even in a shallow well, and snow is extremely economically and effectively removed. In addition, the two wells can be used alternately in summer and winter to enable both direct watering and indirect heating, and the method of always returning used groundwater to the wells will cause ground subsidence. Demonstrate excellent features such as mist.
