FIELD: construction.;SUBSTANCE: invention relates to construction, namely, to soil deformation measuring devices. Device for measuring shear deformations of soil relative to surface of concrete structure includes bench in form of pipe with side longitudinal through slot, sensitive element connected to transfer rod, bushing, meter of linear displacements. To provide axial movement of the transfer rod is located in bushings, one of which is made in form of detachable cover, and other is fixedly installed in internal cavity of reference point above side longitudinal through slot, and in lower part is pivotally connected along its axis with sensitive element in its middle part, and transmission rod upper part is equipped with linear displacement meter. One end of the sensitive element is pivotally connected to the reference mark and the other end is inserted into the side longitudinal through slot of the reference mark in order to enable its displacement into the ground beyond the outer surface of the reference mark of not less than 15 mm in the initial position perpendicular to the axis of the transfer rod, or for partial exit from soil in turned position, or for complete entry into reference cavity through side longitudinal through slot in extreme turned position.;EFFECT: technical result consists in improvement of accuracy and reliability of measurement results of shear deformations of soil relative to surface of concrete structure.;1 cl, 4 dwg
