Introduction

The geosynthetic material blockage test apparatus is used for the test of geosynthetic material filter layers. It employs the gradient ratio method to measure the permeability coefficient and permeability ratio of the soil and the geosynthetic fabric system as well as their interfaces under non-pressure conditions, and also measures the mud content of the geosynthetic fabric to determine whether an unacceptable blockage occurs when the geosynthetic material is used as a filter layer for a certain type of soil.

The features are as follows

It is applicable to various soil types and geotextiles.

Floor-standing model design, stable body structure, not prone to deformation;

The organic glass testing chamber enables a clear observation of the clogging process of the geotextile.

The device for holding the sample in the test cylinder has a good sealing performance, ensuring the feasibility of the test.

The height of the test cylinder is designed reasonably, leaving a certain space above the soil sample to ensure uniform and stable water flow.

Manually rotate the handwheel to drive and adjust the water level, which is efficient and smooth.

Six pressure measurement tubes facilitate pressure observation and have high measurement accuracy.

It is easy to install and convenient to operate.
