Abstract
The utility model discloses a frost heave factor for soil property, which comprises a tester box body formed by an upper portion and a lower portion. The lower portion of the tester box body is a Freon cooling chamber controlled by a power device, and the power device is connected with a controller through a wire. The upper portion of the tester box body is a measuring chamber, the Freon cooling chamber is connected with the measuring chamber through a temperature transmission plate which is provided with a soil sample test-piece mould, and the soil sample test-piece mould is provided with a displacement sensor which is connected with a display instrument. The frost heave factor tester for the soil property reduces other influencing factors, is capable of directly measuring frost heave state of soil samples under low temperature, has high detection accuracy, improves measurement efficiency, and provides quality guarantee for construction of buildings and roads.
