FIELD: building, particularly building-and-engineering researches to investigate deformation ground properties.
SUBSTANCE: device has thrust structures including bearing plate connected with base by supports, mechanism for applying axial load to ground sample mounted on base and dynamo-metering structure. Dynamo-metering structure is made as frame formed by two longitudinal tie rods and two transversal beams. Cross-section of upper beam has the shape of horizontal H-bar along axis of plant symmetry. Strain gage transducers are arranged on working shoulders of H-bar, support part for sensing forces to be measured is connected to wall thereof.
EFFECT: increased measuring accuracy, reduced measuring time.
