Coarse-Grained Soil Direct Shear Compression Testing Machine

Product introduction

ZY50-2G coarse-grained soil direct shear testing machine conforms to the national standard GB/T 50123-2019 "Soil Test Regulations" of the People's Republic of China. Special equipment for the determination of shear strength and time-dependent deformation of coarse grained soil. Coarse-grained soil compression testing machine conforms to the national standard of the People's Republic of China "Soil Test Regulations" GB/T 50123-2019. Special equipment for measuring the relationship between deformation and pressure of coarse granular soil, the relationship between deformation and time, in order to calculate the compression coefficient, compression index, rebound index, volume compression coefficient, compression modulus, consolidation coefficient and pre-consolidation pressure of soil.

Main functions and characteristics

1. Comply with the group standard T/CHES 29-2019 "Coarse-grained Soil Test Rules" and the Ministry of Electric Power of the People's Republic of China DL/T5356-2006 "Coarse-grained Soil Test Rules for Hydropower Projects";

2. Mainly used for the study of engineering geology and geological disasters in the process of geotechnical materials engineering properties, landslide stability evaluation of high-end research equipment.

3. The equipment can do direct shear test and compression test at the same time, do not interfere with the data;

4. Coarse-grained soil direct shear testing machine adopts frame type, coarse-grained soil compression testing machine adopts two-column frame, direct shear box is two-layer circular shear box, opening height can be adjusted;

5. The high pressure oil source pump station provides loading force, and the pressure is stabilized by the special electro-hydraulic proportional valve and 10L accumulator during the shutdown of the pump station, so the high pressure oil source pump station does not need to run for a long time, the system is energy-saving and does not need to be equipped with cooling system;

6. Vertical load and horizontal thrust are measured by load sensor, vertical settlement and horizontal shear displacement measured by resistance ruler;

7. The equipment for microcomputer automatic control, supporting automatic data acquisition system; All test parameters are controlled, stored, measured, displayed, processed and printed by computer.
