I. Overview

  TSZ series strain control triaxial instrument is one of the main products of our company, and it is the main conventional test instrument for the current geotechnical test. Over the years, we have continued to improve the product, the product performance has been continuously improved, and the product has been continuously updated to meet the requirements of SL 237 -1999 "Geotechnical Test Regulations", JTG E40-2007 "Highway Geotechnical Test Regulations", TB10102-2010 "Geotechnical Test Regulations for Railway Engineering", GB/T50123-2019 "Geotechnical Test Method Standard".

2. Main use

It is used to determine the shear strength, deformation characteristics and pore water pressure of soil samples under equal strain loading. The instrument can perform shear tests such as Unconsolidated Undrained Shears (UU) , Consolidated Undrained Shears (CU) and Consolidated Drained Shears (CD) . The strain control method is controlled by the single-chip microcomputer to realize stepless speed change; the surrounding pressure and back pressure are controlled by the single-chip microcomputer. The instrument has stable and reliable performance, simple operation and compact structure.
