PROBLEM TO BE SOLVED: To improve efficiency in an installation work of a heat exchanging pipe into a vertical hole.SOLUTION: In an installation jig 1, a cross-shaped attachment member 7 is fixed on an inner surface 3 of a wall panel of a rectangular cylinder 2 which vertically opens, and an insertion member 8 is fixed to the attachment member 7 in which an upper end of the insertion member 8 is projected upwardly from an upper end of the rectangular cylinder 2 (a). A pipe material 12 is bent to form a vertically-folded heat exchanging pipe 10, and a lower bent part 13 over which a reinforcement pipe 16 is covered is fixed to an outer surface 4 of the installation jig 1 (b, c). The insertion member 8 is inserted into a hollow hole at a lower end of a push-in rod 33. The push-in rod 33 is mounted on an auger of an excavator, in which the push-in rod 33 is positioned at an upper part of a vertical hole by pulling up the heat exchanging pipe 10 by a winch provided to the auger. The auger of the excavator is lowered to insert the heat exchanging pipe 10 with the installation jig 1 and the push-in rod 33 into the vertical hole, and then pull up the push-in rod 33 from the vertical hole.SELECTED DRAWING: Figure 1
