Title:

IN-SITU CONCRETE PILE AND GEOTHERMY UTILIZING METHOD USING THE SAME

Document Type and Number:

Japanese Patent JP3886469

Kind Code:

B

Abstract:

PROBLEM TO BE SOLVED: To provide an in-situ concrete pile having problem-free strength, allowing easy embedding of a heat medium circulation pipe deeply into a ground to utilize geothermy at low cost while saving construction cost.
SOLUTION: The heat medium circulation pipe 4 in which heat medium is circulated is formed into a cylindrically spiral shape. The heat medium circulation pipe 4 is arranged in a pile hole 1 and a steel pipe 3 is arranged on the outer periphery of the heat medium circulation pipe 4. Concrete is placed into the whole pile hole 1 to give strength as designed to the outer periphery side of the heat medium circulation pipe 4.
