SOIL NAIL STRUCTURE WITH GEOTHERMAL HEAT EXCHANGE PIPE AND CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: A soil nail structure with a geothermal heat exchanger and a construction method thereof are provided to reduce costs and to prevent a supporting body and a protecting member from being in contact with a geothermal heat exchanger by equipping the supporting body and protecting member at the front end of the soil nail. CONSTITUTION: A soil nail structure with a geothermal heat exchanger comprises a soil nail(100), geothermal heat exchanger(200), a grouting groove, a spacer(300), and a supporting body(400). The supporting body supports a bending unit by preventing sagging. The protecting member prevents the geothermal heat exchanger from being damaged by being in contact with a projection unit. The construction method of a soil nail structure comprises the following steps: drilling a plurality of insertion holes(11) on the construction surface and subsequently inserting a soil nail structure to each insertion hole; closing the inlet of the insertion hole by injecting foaming medicinal fluid into a packer and subsequently grouting a filler inside the insertion hole; circulating refrigerant to the geothermal heat exchanger, curing the filler, and installing anchor plate to the inlet of the insertion hole; and interconnecting the geothermal heat exchanger which is inserted into the insertion holes and applying shotcrete on the construction surface.
