摘要
PROBLEM TO BE SOLVED: To reliably insert a probe rod in soil even in soft ground or hard ground without damaging it, prevent soil collapse of an insertion hole, and highly accurately measure soil thermal resistance.;SOLUTION: The probe rod 51 is inserted in soil (s) to measure temperature changes when the probe rod 51 is heated by a thermal source for a prescribed time. Thermal resistance is determined on the basis of its temperature gradient. Guide bars 1 and 11 are driven or screwed in the soil (s) in measuring the soil thermal resistance to form the insertion hole 52 in a vertical direction, inject a fluidic body 4 in the insertion hole 52, and insert the probe rod 51 in the fluidic body 4.;COPYRIGHT: (C)2008,JPO&INPIT
