<P>PROBLEM TO BE SOLVED: To provide a heat exchange pile in which pile bodies can be sank by a method similar to a general pile construction, a space for disposing heat exchange pipe materials between the pile body and the wall of an excavated hole is secured by setting folding parts of the heat exchange pipe materials at an upper part of a lower pile increased in the diameter, the structure is formed receiving no large resistance even at the rotary sinking, and no short circuit is caused by providing a positioning member allowing separate setting of the pipes for feeding a heat exchange medium and pipes for taking out the heat exchange medium, and to provide an installation method of the heat exchange pile. <P>SOLUTION: In the heat exchange pile, a plurality sets of U-tubes 4 extendedly set in the pile longitudinal direction for allowing vertical circulation of the heat exchange medium like an antifreeze are juxtaposedly attached in the pile circumferential direction around an outer periphery of the shaft part 3 of the pile body 1 having an increased diameter part 2 near the end. <P>COPYRIGHT: (C)2012,JPO&INPIT |
