This direct shear preloader is a specialized pre-consolidation apparatus designed to apply controlled vertical pressure to soil samples prior to fast direct shear testing, ensuring proper drainage and specimen stabilization.

Duodenary Direct Shear Pre-Pressing Apparatus

Model:TGSYL-2

I.Product Introduction

This instrument applies vertical pressure to soil samples and is a specialized pressure apparatus for providing specimens for consolidated rapid shear tests after soil samples have been drained and stabilized.Its features include:each container can hold three soil samples,high utilization rate,small footprint,and unique design.Compliant Standards:GB/T50123-2019"Standard for Geotechnical Testing Methods"and ISO 17892-10:2018—Geotechnical investigation and testing—Laboratory testing of soil—Part 10:Direct shear tests.

II.Product Features

1.Employs the lever principle,equipped with a complete set of weights,with a lever-to-lever ratio of 1:12,for pre-compression and consolidation of the specimen.

2.Equipped with a standard pre-compression container,providing a saturated air environment throughout the soil sample pre-compression process,improving data accuracy.

3.Standard configuration includes 12 sets of pre-compression devices,allowing for the pre-compression of up to 36 specimens at a time.
