APPLICATION:
It is used to measure the direct shear friction and pull friction test of geosynthetics under dynamic (static) normal pressure.
STANDARDS:
1. Direct shear test:ISO12957.1, GB/T 17635.1, ASTM D5321, JTG E50 T1129, SL/T 235
2. Pull test: JTG E50 T1130, SL/T 235
INSTRUMENT CHARACTERISTICS:
1. The structure design is simple and practical, and the patented dynamic normal loading mechanism provides more than one time of simulated experimental conditions beyond the actual working conditions;
2. Equipped with a mobile device to make the work of replacing the cutting box, drawing the test box and sample fixture more labor-saving and quick;
3. The function conversion is convenient, and the exchange of direct shear test and pull test can be completed by simple operation;
4. The brand servo drive system makes the displacement accuracy higher and the speed more accurate;
5. Premium brand sensor for more accurate measurement;
6. The normal pressure adopts the pneumatic principle and is equipped with a precision control valve to make the pressure more accurate and stable;
7. The control panel is made of imported special aluminum profiles and equipped with metal buttons.
8. Premium brand color touch screen display;
9. Important parts are processed by special materials (such as test box, pulley, pressurizing mechanism, etc.).
