The core function of this instrument is to apply a vertical load to the frozen soil without disturbing its original structure and stress state in order to determine its key mechanical parameters such as compressibility and deformation modulus.

In-situ Frozen Soil Compression Tester

Model:TGSYB-1

I. Product Introduction

The TGSYB-1 In-situ Frozen Soil Thaw Compression Tester is developed and manufactured by our company according to the test requirements of Section 39, "In-situ Frozen Soil Thaw Compression Test," in the national standard GB/T 50123-2019 "Geotechnical Testing Methods." It is mainly used for indoor determination of the volumetric sedimentation coefficient and thaw compressibility coefficient of undisturbed frozen soil. It is used for calculating the thawing and compression settlement of frozen soil foundations. This instrument is suitable for frozen soil strata formed from various types of soil except for boulders.

Meets the following test standards:

GB/T50123 "Standard for Geotechnical Testing Methods";

TB10102-2010 "Railway Geotechnical Testing Procedures";

ASTM D5520 — Laboratory determination of creep properties of frozen soil by uniaxial compression

ASTM D7300 — Laboratory determination of strength properties of frozen soil at a constant rate of strain
