MEASURING APPARATUS OF FROST HEAVING PRESSURE FOR EARTH AND SAND

摘要

PURPOSE: A freezing test device for soil is provided to measure physical properties caused by freezing positively, variously, and continuously. CONSTITUTION: A freezing test device for soil includes a soil tub (10), a freezing unit (20), and a measuring unit. A specimen (2) is filled in the soil tub. The measuring unit is installed on either of the upper and lower sides of the soil tub and freezes the specimen. The measuring unit measures a frost heaving force of the specimen inside the soil tub. The measuring unit includes a transmission unit (32) which is installed on the upper or lower side of the soil tub and outputs signals; and a reception unit (34) which is installed on a side of the soil tub and receives the signals output from the transmission unit.
