Title:
DIGGING OF HEAT EXCHANGE WELL, UNDERGROUND HEAT EXCHANGE SYSTEM AND SETTING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3902515
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To improve working efficiency by using a digging rod as a heat-exchanging pipe too.
SOLUTION: By utilizing an underground heat exchange pipe wherein at least two pipe materials are disposed in parallel to each other, high-pressure water is passed through one steel pipe 3, and the high-pressure water is jetted from jetting ports 6 disposed in a lower part of the steel pipe 3 to dig the ground and to dig a heat-exchanging heat exchange well 1. When the digging is completed, the jetting ports 6 for jetting the high-pressure water are closed, and the steel pipe 3 and a polyethylene pipe 4 communicate with each other by opening an opening/closing valve 10 to form an underground heat-exchanging heat exchanger 2.
