Title:
地中熱利用のための既製コンクリート杭及び地中熱利用システム
Document Type and Number:
Japanese Patent JP5895306
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a precast concrete pile for underground heat use and an underground heat using system which is improved in the thermal conductivity of a concrete pile and increased in heat exchange efficiency with ground.SOLUTION: A hollow precast concrete pile 1 having an annular metallic end plate 2 at an end part thereof includes a thermal conductor 10 which is extended in a pile axial direction in the inner periphery of a pile body 1a, and which is more excellent in thermal conductivity than concrete, and the end part is joined to the end plate 2. Thus, the transfer of heat between a heat exchange pipe 8 and a peripheral ground 11 disposed in the pile body can be accelerated, and heat exchange efficiency can be improved.
