<p><P>PROBLEM TO BE SOLVED: To solve problems wherein the concrete can not be sufficiently deposited to a part where the heat exchanging pipes are placed among main reinforcements in a state of being internally kept into contact with a hoop reinforcement of a reinforcement cage, when the heat exchanging pipes are placed in a cast-in-place foundation pile, and the cost is increased in accompany with the increase of materials and man-hours when a method of installing the heat exchange pipes in the reinforcement cage of a small diameter concentrically mounted inside the main reinforcement cage, is applied. <P>SOLUTION: In this heat exchanging pipe installing mechanism, supporting reinforcing bars 5 are arranged among a plurality of sets of main reinforcements 3 placed oppositely to each other on a plurality of parts at intervals in the longitudinal direction, of the reinforcement cage 2 constructing the cast-in-place foundation pile, the heat exchanging pipes 7 are supported at their intersecting parts as supporting parts, and a tremie pipe is inserted through a space part formed at a center side. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
