GEOTHERMAL HEAT COLLECTION FUNCTION-INTEGRATED HYBRID SCREW PILE
PROBLEM TO BE SOLVED: To provide a geothermal heat collection function-integrated hybrid screw pile capable of efficiently collecting geothermal heat without deteriorating a function for being served by the screw pile.SOLUTION: A hollow tube 2 for heat exchange, which is buried into the ground to circulate a heat exchange liquid or groundwater thereinto, is formed in a spiral shape with the same radius and the same pitch, and its tip is formed in a sharp-pointed shape. Additionally, an interior tube 3, which is spirally formed to the vicinity of the tip along the hollow tube 2 for heat exchange, is provided within the hollow tube 2 for heat exchange, and a circulation port 31 enabling circulation into the hollow tube 2 for heat exchange can also be formed near the tip of the interior tube 3.
【課題】 螺旋杭としての機能を損なうことなく、効率よく地中熱を採熱することのできる地中熱採熱機能一体型ハイブリッド螺旋杭を提供する。【解決手段】 地中に埋設されてその内部に熱交換液または地下水を流通させる熱交換用中空管２であって、前記熱交換用中空管２を同一半径で同一ピッチの螺旋状に形成するとともにその先端を先鋭状に形成してなる。また、前記熱交換用中空管２の内部には、前記熱交換用中空管２に沿って先端近傍まで螺旋状に形成された内装管３が設けられており、当該内装管３の先端近傍には前記熱交換用中空管２の内部と流通可能な流通口３１が形成されていてもよい。【選択図】 図１
