PURPOSE: A construction method of a geothermal heat exchanger is provided to conveniently construct a geothermal heat exchanger in a deep excavated hole. CONSTITUTION: A construction method of a geothermal heat exchanger is as follows. A reinforcing material is split into upper and lower reinforcements(100,200) in the longitudinal direction of an excavated hole. A holder(30) is installed in the lower reinforcement to hold an underground heat exchanger when pulling up a rope member(10). The rope member is hung on the holder and the lower reinforcement is inserted in the excavated hole. The bottom of the upper reinforcement is fixed to the top of the lower reinforcement. The U-shaped end of the underground heat exchanger is fixed to one end of the rope member. The rope member is hung on the holder and the joined reinforcing material is inserted in the excavated hole together with the roper member and the underground heat exchanger. The rope member is pulled up until the U-shaped end of the underground heat exchanger is caught by the holder. |
