Title:
熱交換用配管、鉄筋籠及び地中熱利用システム
Document Type and Number:
Japanese Patent JP5834873
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide piping for heat exchange which hardly causes occurrence of damage or malfunction even when mounted to a reinforcement cage inserted into a drilling hole for constructing a cast-in-place pile and when contacting with the inner wall surface of the drilling hole during the insertion and which can be arranged at a position closer to the inner wall surface or the inner wall surface side of the drilling hole from the side of the reinforcement cage inserted into the drilling hole, a reinforcement cage equipped with the piping for heat exchange, and a geothermal heat utilization system using a cast-in-place pile constructed by the reinforcement cage.SOLUTION: Piping 6 for heat exchange which performs heat exchange with the underground is mounted to the outer periphery or outer peripheral side of a reinforcement cage 2 inserted into a drilling hole 1 when constructing a cast-in-place pile and is movable from the inner wall surface of the drilling hole 1 to the reinforcement cage 2 side.
