Consolidated Fast Shear Test Machine Drained Repeated Direct Shear Testing Apparatus Highway Geotechnical Direct Shear Tester
Description
Our company's fully automatic direct shear tester is used to determine the shear strength of soil. It features a high-resolution color screen display and intelligent microcomputer control, achieving automation, ease of operation, high precision, stable speed, reliable performance, and an attractive appearance. The instrument uses a high-performance stepper motor as the drive source, significantly reducing vibration. The electric shearing rate is selectable and can be quickly changed. It is easy to use, durable, and supports simultaneous shearing of four samples. It has an automatic stop mechanism upon returning to its starting position. Key features include: the transmission method has been changed from the original DC speed-regulating motor to a compact stepper motor; the motor power supply has been changed from 220V to 48V; and the lever force point has been improved from the original knife-edge type to a bearing type. This product comes standard with our fully automatic direct shear tester PC testing software, which automatically measures settlement deformation during testing, allows for manual graded loading, automatically calculates test results, displays various test curves, and outputs reports.
This instrument is mainly used to determine the shear strength of soil. Typically, four soil samples are used. Shear stress at failure was determined by applying horizontal forces under different vertical pressures (400 kPa, 300 kPa, 200 kPa, 100 kPa, and 50 kPa selectable). Then, the shear strength parameters, internal friction angle, and cohesion of the soil were determined according to Coulomb's law.
Product Design Standards
T0140-2019 Slow Shear Test, T0141 Consolidated Fast Shear Test, T0142 Fast Shear Test, and T0 176-2007 Drained Repeated Direct Shear Test, as specified in JTG 3430-2020 Highway Geotechnical Testing Standards.
Product Features
1. Direct selection of 5 speeds (0.02~2.4) mm/min or stepless speed adjustment
2. 10-inch LCD display, user-friendly and aesthetically pleasing interface.
3. Shear displacement has limit protection.
4. Equipped with a two-stage reducer and high-precision stepper motor driver, vibration-free at the lowest speed.
5. Horizontal pressure uses a high-precision pressure sensor, with small measurement error and high acquisition accuracy.
6. Horizontal deformation and axial settlement deformation are tested using a digital dial indicator, with high data stability.
7. The independently developed PC version of geotechnical testing software supports fully automated testing, data acquisition and recording, display of various parameter curves, automatic calculation of test results, and complete report output that meets standard requirements.
