CAST-IN-PLACE STEEL PIPE CONCRETE PILE
PROBLEM TO BE SOLVED: To provide a cast-in-place steel pipe concrete pile that enables utilization of underground heat and that enables construction of a pile with great bearing capacity.SOLUTION: A cast-in-place steel pipe concrete pile 1 includes a steel pipe concrete part 2 that is formed in an upper part, and a reinforced concrete part 3 that is formed in a lower part. A filling part 2a, in which concrete 4 continuing into the reinforced concrete part is infilled into a steel pipe, and a non-filling part 2b, in which the upper concrete is not infilled into the steel pipe, are formed in the reinforced concrete part. A heat exchange part 72 of a heat exchange pipe 7 is formed in the non-filling part.
【課題】地中熱利用が可能なうえに高支持力の杭を構築できる場所打ち鋼管コンクリート杭を提供する。【解決手段】上部に形成される鋼管コンクリート部２と下部に形成される鉄筋コンクリート部３とを備えた場所打ち鋼管コンクリート杭１である。そして、鋼管コンクリート部には、鉄筋コンクリート部に連続するコンクリート４が鋼管の内部に充填される充填部２ａと、その上方のコンクリートが鋼管の内部に充填されない非充填部２ｂとが形成され、非充填部には熱交換パイプ７の熱交換部７２が形成される。【選択図】図１
