This is an experimental device that simulates the horizontal flow of water in coarse-grained soil and measures soil deformation. It can simultaneously obtain permeability and mechanical deformation properties, providing important experimental data for water conservancy, roadbed, embankment, earth dam and foundation engineering.

Coarse Soil Horizontal Permeability Tester

Model:TGSYU-1

I. Introduction

This test conforms to GB/T 50123-2019 Geotechnical Testing Methods and ASTM D2434-22 Standard Test Methods for Measurement of Hydraulic Conductivity of Coarse-Grained Soils.The test method uses a seepage flow from left to right and is suitable for coarse-grained soils.It is used to determine parameters such as permeability coefficient,dry density,porosity,seepage gradient,and seepage velocity of coarse-grained soils.
