工程とを連続して行う施工方法である．[Industrial Application Field] This invention relates to a method for constructing an in-well heat exchange non-sprinkling water lightning extinguishing facility for melting snow falling on roads in snowy and cold regions and also preventing road surfaces from freezing. A heat exchanger is lowered and installed along with a water pump to increase the efficiency of heat exchange with groundwater, and a circulation pump is used to circulate the antifreeze filled in the heat exchanger and heat radiation pipes buried in the road surface. , There is no heat exchange inside the well to evenly melt the snow that falls on the road surface and prevent freezing. Concerning construction methods for water sprinkler snow removal facilities. [Conventional technology] The conventional construction method for waterless snow removal facilities is to install only a pump in the pumping well, a heat exchanger above ground, and a separate injection pipe for returning used groundwater underground. It was led into a reinjection well that had been set up. In addition, heat dissipation pipes are buried in the road surface, and a circulation pump is interposed between them and the above-ground heat exchanger to circulate the antifreeze liquid filled in the pipes. They were melting falling snow and preventing freezing. [Problem to be solved by the invention] However, in the conventional construction method of waterless snow removal facilities, only a pump was installed in the pumping well and a heat exchanger was installed above ground. In winter, the heat exchanger is cooled by the cold outside air, resulting in large heat loss, resulting in poor heat exchange efficiency and low temperature of the antifreeze liquid, making it difficult to remove snow uniformly from the road surface. Therefore, in order to prevent heat loss due to the cold outside air, it was necessary to construct a special thermal insulation facility and an above-ground heat exchanger hangar, which made the construction process diverse and complicated, and the time required for the entire construction work was also extended. It had many drawbacks, including being expensive. In order to eliminate many of the above-mentioned drawbacks, the present invention installs a heat exchanger together with a water pump in the well, extremely minimizes heat loss during heat exchange, and increases heat exchange efficiency, thereby achieving uniform snow removal from the road surface. The purpose of this study is to provide a method for constructing an in-well heat exchange waterless snow removal facility that is inexpensive and easy to construct. [Means for Solving the Problems] In order to achieve the above object, the present invention includes a first step of excavating pumping wells and injection wells deep underground at appropriate intervals above the road surface, and a pumping pump installed in the pumping wells. The second step is to lower and install the in-well heat exchanger connected to the heat exchanger, and the heat exchanger is buried in the heat exchanger tube side and the paved road surface via a circulation pump on the inlet side or outlet side of the heat exchanger tube side. a third step of connecting a sending main pipe and a return main pipe so that the lift pump and the circulation pump are operated and stopped in response to a signal emitted by a snow detector installed on the ground; a fourth pipe, and a fourth pipe connecting the return main pipe and a heat dissipation pipe buried and fixed in the paved road surface to form a circulation pipe, and filling the inside of the circulation pipe with antifreeze.
This is a construction method in which the steps are performed consecutively.

Circulates the antifreeze filled inside. For this reason, warm antifreeze is smoothly sent inside the heat dissipation pipes buried and fixed in the road surface, and this heat is evenly transmitted and stored within the road surface, which uniformly melts snow falling on the road surface and prevents freezing. I do. Furthermore, when the snow removal is completed, the operation of the two pumps is automatically stopped by the signal emitted by the snowfall detector. [Example] Next, an example of the construction method according to the present invention will be described with reference to the drawings. (First Embodiment) FIGS. 1 to 3 show an embodiment in which the present invention is applied to a road surface. First, in the first step, 30m to 150m of ground is placed on the road surface 12.
Pumping well 1 and injection well 2 are drilled at appropriate intervals. Pumping well 1 has a completed upper diameter of 100 mm or more and a depth of 30 m.
The injection well 2 has a completed upper diameter of 100 m.
As mentioned above, the depth is shallower than the depth of the pumping well. In the second step, an in-well heat exchanger 4 with a groundwater pump 3 connected to its lower part is installed underground in the pumping well 1. As shown in FIG. 3, the heat exchanger 4 has a large number of small-diameter heat exchanger tubes 5 and one large-diameter heat exchanger tube 6 arranged at appropriate intervals, and the large-diameter heat exchanger tube 6 has a large number of small-diameter heat exchanger tubes 5 and one large-diameter heat exchanger tube 6 arranged at appropriate intervals. The warm antifreeze that has gained heat flows outside the pipe and gives it heat, and in order to prevent it from becoming cold due to the heat being taken away by the cold underground water, insulation material 7 is placed in the middle.
It is more effective to wrap the cloth around it to keep it warm. A large number of heat exchangers 4 can be connected in the vertical direction, and a header 8 is provided at the bottom so that the inside of the small-diameter heat exchanger tube 5 and the inside of the large-diameter heat exchanger tube 6 are communicated. Furthermore, by lowering the heat exchanger 4 into the well, the casing pipe 9 of the well serves to keep the body of the heat exchanger warm, allowing effective heat exchange and further improving thermal efficiency. An overflow pipe 1o is also provided at the top. Next, in the third step, a main feed pipe 13 buried in the heat exchanger tube side of the heat exchanger 4 and the paved road surface 12 is connected to the inlet side or the outlet side of the heat exchanger tube side of the heat exchanger 4 via the circulation pump 11. A pipe 15 for injecting cold water into the underground after supplying heat to the groundwater is connected to the return main pipe 14, and is led into the injection well 2, and the water pump 3 and the circulation pump 11 are connected to the ground. When the snowfall detector 17 installed at
It is also connected so that it will issue a signal and start operating when it snows. In the fourth step, the heat dissipation pipe 1 is inserted into the paved road surface 12 from the surface.
The depth to the center of 6 is 30l ~ IOCII1 depth,
The heat dissipation pipes 16 are buried with an interval of 10a1 to 2o, the material of the heat dissipation pipes 16 is steel pipe or polymer resin pipe, the inner diameter is 9m to 36m, and the buried form is meandering, bent or parallel. It is buried in an appropriate shape, such as a spiral or zigzag shape. It is also possible to fix an iron mesh on the upper or lower surface of the heat dissipation tube 16 to promote heat conduction. The heat radiation pipe 16 buried and fixed in this way, the main feed pipe 13, the heat exchanger 4 on the heat transfer tube side, and the main return pipe 1
4 are connected to form a circulation pipe, and the inside of the circulation pipe is filled with antifreeze, so when it snows, it is heated to over 12°C by receiving heat from groundwater at 15°C to 18°C. The flow rate of antifreeze is 0.3 m/sec to 1. It circulates in the pipe at a speed of 5 m/sec. The above-mentioned road surface 12 can be applied to, for example, roads, sidewalks, parking lots, bridges, railway platforms, airport runways, port wharves, etc., and can be appropriately installed and implemented on any road surface that requires snow removal. ．． (Second Embodiment) As shown in FIG. 4, the second embodiment differs from the first embodiment in that an injection well 2 for underground return of groundwater whose water temperature has been lowered by applying heat is excavated outside the road surface 12. This is a construction method for an in-well heat exchange waterless snow removal facility featuring the following features: (Third Embodiment) In the third embodiment, as shown in FIG. This is a construction method for an in-well heat exchange non-sprinkling snow melting facility characterized by drainage. (Fourth Example) As shown in FIG. 6, the fourth example differs from the first example in that a groundwater pumping well 1 is provided outside the road surface 12, and the groundwater whose water temperature has been lowered by providing heat is added to the groundwater. This is a method of constructing an in-well heat exchange non-sprinkling snow melting facility, characterized in that the reinjection injection well 2 is provided at a different position on the road surface 12. (Fifth Embodiment) As shown in FIG. 7, the fifth embodiment differs from the fourth embodiment in that the injection well 2 for underground return of groundwater whose water temperature has been lowered by providing heat is placed at a different location outside the road surface 12. This is a construction method for an in-well heat exchange non-sprinkling snow removal facility, which is characterized by being installed in a well. (Sixth Embodiment) As shown in FIG. 8, the sixth embodiment differs from the fourth and fifth embodiments in that the injection well 2 for underground return of groundwater whose water temperature has been lowered by providing heat is not provided, and the road surface 12 is This is a construction method for an in-well heat exchange non-sprinkling snow removal facility that is characterized by draining water to the outside. [Effects of the Invention] The construction method for the in-well heat exchange non-sprinkling snow removal facility according to the present invention has the following effects. This invention simplifies the construction procedure, shortens the construction period, and reduces construction costs.Furthermore, because the heat exchanger is not cooled by cold outside air due to the insulation effect of the earth, the heat exchanger expands. This has the effect of reducing shrinkage, extending the lifespan, and improving heat exchange efficiency since heat exchange takes place underground. In addition, by pumping up groundwater from a pumping well and exchanging heat with a heat exchanger inside the well, heat exchange efficiency is increased, and this heat is transferred to the antifreeze inside the heat transfer tube of the heat exchanger, allowing the antifreeze to be heated efficiently. By using a circulation pump to send heat into heat dissipation pipes buried in the road surface and storing it within the road surface, it is possible to evenly and efficiently melt snow falling on the road surface and prevent it from freezing. In addition, this invention installs an in-well heat exchanger together with a pump in a pumping well, and uses one well for multiple purposes, so there is no need for a special hangar on the ground, and the heat exchanger can be kept warm and insulated. No construction is required. Furthermore, snow detectors are installed on the ground, and water pumps and circulation pumps are operated only when it snows or freezes to remove snow from the road surface and prevent it from freezing, which eliminates mindless operation and reduces maintenance costs. has.
