Title:
地中熱採熱機能一体型ハイブリッド螺旋杭
Document Type and Number:
Japanese Patent JP5584839
Kind Code:
B1
Abstract:
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.
