ZJ Strain Controlled Direct Shear instrument (Manual)
简要描述： This instrument is used to measure the shear strength of soil. By using four samples, under different vertical pressures, apply horizontal shear force for shearing, and obtain the shear stress at failure.
产品介绍
I. Overview
ZJ-type strain-controlled direct shearing instrument is one of the main products of our company. It is the main conventional test instrument for the current geotechnical test..
2. Main use
This instrument is used to measure the shear strength of soil. By using four samples, under different vertical pressures, apply horizontal shear force for shearing, and obtain the shear stress at failure. Then the shear strength parameters, internal friction angle and cohesion of the soil are determined according to Coulomb's law.
3. Main technical parameters
1. Maximum vertical load: 400kPa
2. Pressure classification: 50, 100, 200, 300, 400kPa
3. Leverage ratio: 1:12
4. Number of cutting boxes: 1 set
5. Specimen area: 30cm2
6. Horizontal shear force: 1.2kN
7. Shearing rate: manual (the displacement of the push rod per revolution of the handwheel is 0.2mm )
4. Instrument configuration
