BENCH FOR SIMULATING SOIL DEFORMATION PROCESS WITH A SEALANT Russian patent published in 2020 - IPC G09B23/40 G01N3/10 E02D1/00 

FIELD: test technology.

SUBSTANCE: invention relates to investigation of process of solid media deformation. Stand includes two plates (1) and (2), between which test material (3) is placed. In order to inject sealing substance (5) into test material (3) in test bench there is hole (4), in which loading device is fixed. Hole is made so that its axis is parallel to surfaces of plates (1) and (2) adjoining to the tested material and equidistant from each of them. Test material (3) is laid in the form of strips perpendicular to hole (4) and has different properties in different strips. Loading device is made in form of tube (6) filled with sealing substance (5) with longitudinal slots (7) and piston (8) for displacement of sealing substance (5) from tube (6) into test material (3) through its longitudinal slots (8). One of plates (1) or (2) is transparent, and the bench is equipped with a video camera.

EFFECT: enabling modeling of the process of soil deformation with a sealant through a well, passed in a multilayer soil with different properties in different layers, possibility of simulating the process of displacement of the sealing substance from the well into the multilayer soil, including impact loads.
