In general, fossil fuels such as coal, petroleum and natural gas are used as energy sources for domestic and industrial use. These fossil fuels are rapidly increasing in cost due to depletion of the reserves, and various pollutants Polluting water quality and the atmospheric environment. In recent years, attempts have been made to utilize geothermal energy as an environmentally friendly alternative energy capable of replacing fossil fuels. In the case of the cooling / heating apparatus using the geothermal heat, the energy saving can be maximized by 40% or more compared to the conventional heating / cooling apparatus, and stable operation can be achieved without deteriorating the cooling / heating performance due to the geothermal characteristic that maintains a constant temperature during the year.

1 is a view for explaining a state where a conventional geothermal heat exchange pipe is inserted into a bore hole. 2 is a view for explaining a state in which a band feed roll device for transporting a geothermal heat exchange pipe is disposed close to a bore hole.

As shown in the figure, the geothermal heat exchange pipe B is composed of a first pipe B1 through which a heating medium flows and a second pipe B2 through which a heating medium flows, in connection with a heat pump and performing cooling and heating. In order to apply the heat exchange pipe B to the boreholes H drilled at a depth of about 100 to 300 m from the ground, the heat exchange pipe B is first inserted to the bottom of the bore hole H, A tremie pipe for supplying the grouting G is inserted to the bottom of the hole H and then the grouting G is supplied while gradually discharging the tube from the hole H by bending. Through this process, the interior of the borehole H is filled with the grouting G to complete the construction of the geothermal heat exchange pipe B.

With this structure, the heat medium flowing into the first pipe B 1 and then flowing out to the second pipe B 2 is heat-exchanged with the geothermal heat transferred through the grouting G, and the heat medium is heat- ), And is used for cooling and heating.

The first pipe B1 and the second pipe B2 inserted into the borehole H are formed in the shape of a triangle, Irregularly shaped or irregularly oriented. In this case, it was difficult to insert the bridge pipe to the bottom of the bore hole (B), and the grouting work was delayed.
