PROBE FOR MEASURING UNDERGROUND THERMAL CONDUCTIVITY, UNDERGROUND THERMAL CONDUCTIVITY MEASURING DEVICE, AND UNDERGROUND THERMAL CONDUCTIVITY MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a probe for measuring an underground thermal conductivity capable of improving work efficiency in measurement of the underground thermal conductivity, and preventing damage of both a hole bored in the ground G to be measured and a measuring device.;SOLUTION: This probe is equipped with a heating body sensor 10 and a support 20 insertable into the hole bored in the ground to be measured. The heating body sensor 10 is equipped with a heating casing 11 having an outer surface closely attachable to the soil, a heater 12 for supplying heat to the soil, and a temperature measuring device 13 for measuring a soil temperature. The support 20 is equipped with a support casing 21 connected to the heating casing 10. The support casing 21 is equipped with a storage means 22 for storing the temperature measured by the temperature measuring device 13; a control means 23 for controlling the heater 12, the temperature measuring device 13 or the like; a power supply means 24 for supplying the power to the heater 12 or the like; and an external output terminal 25 for outputting a measured value stored in the storage means 22 to an external information processing device 2.;COPYRIGHT: (C)2009,JPO&INPIT
