PROBLEM TO BE SOLVED: To provide a ground heat collection pipe wherein it can be laid in a narrow site with easy embedding work in the ground, and efficiency of heat delivery with the ground is excellent with easy maintenance, and further to provide a ground heat exchanger using the foregoing ground heat collection pipe, and a ground heat utilization heat exchange system.;SOLUTION: A ground heat collection pipe is embedded in the ground 52, and heat is delivered between the ground and a load through a peripheral wall of a bottomed straight pipe 62t via a heat medium 88 passing through the inside of the straight pipe. A screw-shaped fin 150 is wound around an outer peripheral surface of the straight pipe located in the vicinity of at least a bottom of the same to thread the pipe into the ground, and an excavating blade 144 is mounted at an outer bottom of the straight pipe and inserted into the ground with the rotation thereof. Further, a ground heat exchanger 60 equipped with the ground heat collection pipe is provided, and a ground heat utilization heat exchange system adapted to include the ground heat exchanger is provided.;COPYRIGHT: (C)2003,JPO
