<p>According to characteristic of the present invention, a construction method of an underground heat exchanger comprises stages of: perforating an insertion hole to perforate an insertion hole into which a geothermal loop is inserted on a foundation ground to construct a construction structure thereon; installing a geothermal loop to install the geothermal loop into the insertion hole by insertion; and crushed rock water filling to fill the insertion hole with crushed rock water discharged from the insertion hole which was perforated in the insertion hole perforating stage. According to the present invention, underground thermal conduction rate of cooling, heating machinery facility may be improved using geothermal renewable energy, a grounding machine is not required, and a crushed rock water filling method for improving underground thermal conduction rate can be provided through simple construction and short construction period.</p> |
