4.8mm/min Soil Testing Equipments ZJ Quadruplex Direct Shear Apparatus
ZJ Quadruplex Strain Controlled Direct Shear Apparatus
Application:
ZJ Quadruplex Strain Controlled Direct Shear Apparatus is a kind of strain controlled direct shear apparatus used to test resisting shear strength of soil specimen, it usually adopts four specimens under the different vertical pressure, to exert horizontal force to the specimens, so as to obtain shearing stress while the specimen is damaged. According to Coulomb’ s rule, it is used to confirm the soil resisting shear strength coefficient, angle of internal friction and coagulable force

Features:
1. It usually adopts four specimens under the different vertical pressure (400kPa, 300kPa, 200kPa, 100kPa, 50kPa selectable)
2. It can do other functions: fast shear, slow shear, reciprocating shear
3. If use computer control, configure the collector and sensor, it can realize automatic collection and processing.
4. The instrument will automatically quickly return to the original point after the test is finished.
