FIELD: devices for measurement of ground cryosaltfluctuation displacement; applicable in measurement of ground deformation on slopes in regions of cryolite zones. SUBSTANCE: essence of the invention consists in installation of two bench marks into ground, hollow rods with plates and marks. Tubes are fitted on hollow rods to prevent freezing of rods together with overlaying heaving ground. Deformations are measured by means of rods and flexible cords attached to marks. EFFECT: higher accuracy of measurement of ground displacement values in depth in region of cryolite zone. 1 dwg
