Hangzhou Civit Instrument Equipment Co.,Ltd.
PRODUCT DETAILS
I. USE
It
is a fully automatic test equipment developed by electronic sensor technology,
stepper motor deceleration transmission technology, air pressure loading
technology and computer information processing technology for direct shear
friction and pull-out friction tests of geosynthetics.
The
geotextile direct shear friction test system adopts a ball screw, which is used
for the friction test of the pulling resistance of the geosynthetic material in
the soil and the surrounding soil and the direct shear friction test between
the geosynthetic material and the earth and stone to detect the direct shear of
the geotextile material. friction properties.
II. Feature
1.
adopt the ball screw, which is a precision linear module, with stable drawing
and low noise.
2.
The vertical loading adopts air pressure control, the pressure is stable and
easy to adjust
3. It has the characteristics of uniform tension and constant velocity, light appearance and easy operation.
