C101 Coarse-grained soil vertical permeability deformation tester
Coarse-grained soil vertical seepage deformation tester, this instrument complies with SL237-056-1999 geotechnical test regulations (coarse-grained soil seepage and seepage deformation test) and DL / T5356-2006 hydropower and hydraulic engineering coarse-grained soil test procedures The seepage passage is the critical slope of the sample, and the critical slope of the fine particles gradually lost with the seepage and the failure slope of the soil as a whole. Applicable to coarse-grained soil, used to determine the permeability coefficient, dry density, porosity, seepage slope, seepage velocity and other parameters of coarse-grained soil.

6, constant force mining deformation, time section, force section can be set, the maximum force 0-30KN, deformation 0-50mm / 0.001mm
7. Hydraulic gradient loading device: range 1 ~ 100m (converted by pressure) can be arbitrarily set and loaded. Note this option
The instrument is divided into: automatic servo control test data acquisition and manual control test data acquisition.
Vertical osmosis deformation instrument: includes a barrel, a top cover, a base, a permeable plate and a bracket. The ratio of the inner diameter of the cylinder to the maximum particle size of the sample should not be less than 5, and the height of the sample should not be less than the diameter of the sample. The center of the top cover is a piston sleeve. The permeable board is divided into an upper permeable board and a lower permeable board, and the upper permeable board also plays a role of transmitting load. Below the lower permeable plate, an inclined permeable plate may be provided, and an exhaust hole is provided at the upper end of the inclined permeable plate.
