Geosynthetic Direct Shear Drawing Friction Tester - China

The friction characteristics of the interface of sand/geotextile were determined by testing the contact surface of standard sand/geotextile.

This instrument is suitable for all geotextiles and related products.

The instrument adopts high-precision servo motor.

By testing the pull-out friction resistance of the geosynthetic material and the surrounding soil, the pull-out resistance characteristics of the geosynthetic material were determined.

It is suitable for soil of various soil properties and states and various types of geotextiles, geomembranes, geotextiles and geogrids.

Specification:

For direct shear test, adopt detachable drive unit, which can be moved from one shear box to another, allowing the testing of one sample while another sample is being prepared in a separate box.

For pullout test, the box is removable of a constant rate controlled by the servo motor; it is as same as moving box in direct shear test.

The direct shear test machine consists of servo motor, load cell, control panel, transducer, readouts for the sensors, etc.

The drive system is mounted on a wheeled frame to allow for easy separation from the sample box.

The box has low friction linear bearings when moving.

Digital readout for each test and can be connected to PC for data analysis.

Meet the standard: Direct shear test : IS0 12957.1 - GB/T 17635.1-1998 - JTG E50 T1129 - SL/T 235 - ASTMD5321 - etc Pull test : JTG E50 T1130 - SL/T 235 - etc.

Features:

Direct shear drawing test system is an integrated machine with two functions of direct cutting and drawing, as long as by changing a small amount of tooling fixtures, two test functions can be achieved: Computer upper computer software controls the test process, direct shear and drawing interface friction integration into one, software autonomy is strong, can independently set the experimental conditions of mainstream standards at home and abroad, applicable to mainstream national standards, and can independently complete data processing, to achieve full data export, easy to study the relationship between shear stress and displacement of samples and time, is a comprehensive interface friction test system; The horizontal loading device adopts servo electric cylinder to realize full digital speed closed-loop control, which has the advantages of stable speed, wide speed range and high positioning accuracy, and the stretching speed can be set arbitrarily.

The normal loading device is realized by manual hydraulic or automatic electric cylinder, which is convenient and reliable, and the pressure is stable.

The pin connection technology can quickly and simply change the clamp required for testing; It has a variety of hardware and software protection measures such as overload and over-travel to ensure the safe and reliable operation of the equipment.
