VERTICAL FILTRATION-SUFFUSION DEVICE FOR TESTING LAYERS OF MACROFRAGMENTAL SOIL AND NON-SOIL CONSTRUCTION MATERIAL Russian patent published in 2022 - IPC G01N15/08 

FIELD: construction industry.

SUBSTANCE: invention relates to the field of construction and can be used in laboratory research. The vertical filtration-suffusion device for testing layers of macrofragmental soil and non-soil construction material consists of a filtration chamber (2), a sump (1), upper (14) and lower (21) nozzles for the release of filtered water, a movable load grid (6), a rod (13) transmitting the load, a clock-type indicator (9) to measure the compression deformation of the soil sample, pressure sensor (10). There are devices for air release (8), filtration chamber covers (7), tee taps (17) for regulating the flow of water into tubular piezometers (16) and the release of air from them. The movable support grid (3) is equipped with at least two lifting cables (15). The cables are made of metal of a flexible stranded structure. The movable grid can be removed by a winch (12) from the filtration chamber (2) together with the samples of macrofragmental soil laid on it (5). In this case, the movable support grid (3) is fastened to a sectional telescopic hollow cylindrical support (19), limiting the volume of the tested samples of macrofragmental soil (5). The sections of the sectional telescopic hollow cylindrical support (19) are fastened together with metal studs (22).

EFFECT: expansion of the range of solutions for the construction industry.
