Scope of application:

The method of gradient ratio is used to measure the permeability coefficient and permeability ratio of soil and geotextile system and its interface under no-pressure conditions, and the mud content of geotextile is measured to determine whether the geosynthetic material is used as a filter layer of some soil, and whether the blockage is not allowed.

Meet the standard:

ASTM D5101-2006JTG E50 T1145-2006,SL/T 235-33-2012, etc

Instrument features:

Suitable for all kinds of soil and geotextile;

Floor type design, stable fuselage structure, not easy to deformation:

Plexiglass test chamber can visually observe the silting process of geotextiles:

The seal of the specimen holding device in the test cylinder is good to ensure the feasibility of the test.

The height of the test cylinder is reasonable, and a certain space is reserved above the soil sample to make the water flow uniform and stable.

Manual rotary hand wheel drive, water level regulation, efficient and smooth:

6 pressure gauges for easy pressure observation and high measurement accuracy:

Easy to install, easy to operate.
