DEVICE FOR STUDY OF PROCESSES OF WATER EROSION OF SOILS Russian patent published in 2023 - IPC G01M99/00 

FIELD: laboratory studies.

SUBSTANCE: invention relates to devices for modeling of processes of water erosion of soils in laboratory conditions. The device includes a support structure with a blower, a hydraulic tray, and an adjustable sprinkler equipped with pump (29), located on the structure. A bottom of the hydraulic tray is made in the form of a pyramid with a hole for removal of infiltrate at a lower point. The hydraulic tray is equipped with a system for removal of water outside of it, placed along a perimeter of the tray, as well as a drainpipe for removal of surface drain. At the same time, a layer of soil under study is laid on a draining layer, below which a removable mesh partition is located. The sprinkler contains injector (25) and flow meter (24). The support structure has four legs (17), wherein hydraulic jacks (18) are mounted in two legs from one side of the structure, and two opposite support legs are interconnected with a rotary structure in the form of cylindrical hinge (19).

EFFECT: study of processes of water erosion of soils in laboratory conditions.
