Title:
METHOD AND APPARATUS FOR INSTALLING GEOTHERMAL HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2020098089
Kind Code:
A
Abstract:
To provide an installation method of a geothermal heat exchanger free from delay in a construction work around a borehole.SOLUTION: A geothermal borehole is bored to a target depth at a construction site and then a geothermal heat exchanger is inserted into and then secured in the geothermal borehole at a desired depth. The geothermal heat exchanger has a distal closed end and a proximal opened end, and has at least one fluid path between the distal closed end and the proximal opened end, and a working fluid is supplied to each fluid path of the geothermal heat exchanger. After securing the geothermal heat exchanger in the geothermal borehole and before excavating a geothermal borehole peripheral portion, at least one internal seal material is disposed in each fluid path from the proximal opened end, so that the geothermal heat exchanger is temporarily sealed. For each fluid path, the internal seal material is disposed below a planned ground depth position, and excavation work of the geothermal borehole peripheral portion at the construction site is executed.SELECTED DRAWING: None
