Device for determining the forces of frost heaving of the soil

摘要

The invention relates to the construction, in particular to the technique for determining the tangential forces of frost heaving of the soil, and can be used in surveys, design and construction of buildings and structures. The device includes a hollow metal pipe (2) immersed in the ground (1) with sections (3) installed on it, each of which is made - shaped, interconnected protrusions (4) and grooves (5) through the layer of antifreeze substance (6), anchored below the depth of seasonal soil freezing, and brackets (7) rigidly attached to it (8) ), between which a compression dynamometer (10) is placed, the zero reading of which is displayed before the tests with fastening nuts (11), fixing the immobility of the upper support plate (9). 1 hp f-ly, 3 ill.
