The
frost heaving device of layered telescopic detecting soil and a detecting method thereof are disclosed. In
cold area engineering construction, due to the complicated geological condition of a construction site, the monitoring of frozen
soil frost heaving deformation is difficult, and
frost heaving data at different depths in one area is difficult to acquire at the same time. In the
frost heaving device, a plurality of casing-
pipe-type monomers are successively arranged on a
chassis from bottom to top, an anchor plate is arranged outside a tube body, a displacement sensor is arranged on theinner wall of the tube body, the top end of the tube body is processed with a boss, the bottom end of the tube body is processed with a groove, and the tube body of one casing-
pipe-type
monomer is slidably cooperated with the two adjacent casing-
pipe-type monomers through the boss and the groove. According to the frozen
soil type in a test area, the number of measuring points in the test area andthe distribution position of each measuring point are determined, the
frost heaving amount data of the
frost heaving layer of each measuring point in different time periods is obtained through the
frost heaving device, and according to frost heaving amount data gathering fed back by each measuring point, a frozen
soil frost heaving deformation condition in the test area is obtained. The device and the method are used for the monitoring of the frozen
soil frost heaving amount in a vertical or horizontal direction.
