Device for testing rock-soil thermophysical properties

The utility model relates to a device for testing rock-soil thermophysical properties. A valve (1), a flowmeter (2), a pressure gauge (3), a thermometer (4) and a U-shaped buried pipe (5) are connected at the output end of a water tank (10) in sequence; the other end of the U-shaped buried pipe (5) is connected with a thermometer (6), a pressure gauge (7), a water pump (8) and a valve (9) in sequence; the other end of the valve (9) is connected with the water tank (10); a heating pipe is arranged in the water tank, and the flowmeter (2), the pressure gauges (3 and 7), the thermometers (4 and 6) and a temperature sensor (12) are connected with a data processor (11) respectively. The device for testing the rock-soil thermophysical properties can be used for rapidly measuring and calculating the thermophysical properties of rock or soil, has higher accuracy and is convenient for people to perform scientific development and utilization to the terrestrial heat source.
