At this time, the incoming earth and sand (S) presses the U-shaped tube which is the underground loop tube 40, so there is a high risk of deformation such as the U-shaped underground loop tube 40 is shrunk. .

On the other hand, on the outer circumferential surface of the sedimentation-side leader casing 130, which is the leader casing 100, two pairs of long side projection jaw 131 and a pair of short side projection jaw 132 for earth guides protrude. 7B and 7C, by the protrusion height of each protruding jaw 131 and 132 and the protruding height of each protruding jaw 131 and 132, the earth and sand S which is pushed in when the leader casing 100 is drawn out is the underground loop pipe 40. By deviating from the U-shaped tube, that is, by inducing the first to be pushed away from the space portion, it minimizes the deformation of the U-shaped tube type underground loop tube 40.

For this reason, it is not necessary to provide the loop protector 30 during the embedding process of the underground loop pipe provided in the conventional vertical geothermal heat exchanger, and the U-shaped tube type underground during the penetration and drawing process of the leader casing 100.

The process of embedding the U-shaped underground loop pipe 40 of the U-shaped pipe type by using the underground roof pipe embedding device using the underground loop pipe embedding guide member provided in the vertical geothermal heat exchange device of the present invention configured as described above. The explanation is as follows.

First, the buried vehicle 200 is moved to the buried area of the U-shaped tube type underground roof pipe 40 in which a heat exchange medium is accommodated so that the underground heat can be recovered by the vertical geothermal heat exchanger. Through the open bottom of the leader casing 100 connected to the reader 300 of the 200, the underground loop tube 40 of the U-shaped tube type provided in the vertical geothermal heat exchange device is put in the receiving space 110 Insert to receive (see FIG. 8).

In addition, the ring 121 is installed on the inner side of the mandrel shoe 120 after inserting the U-shaped tube type underground loop pipe 40 provided in the vertical geothermal heat exchanger to the open lower end of the leader casing 100. In the state in which the cable tie 122 is inserted into the U-shaped tube-type underground loop pipe 40 is fixed.
