One, overview

Direct shear apparatus for the determination of shear strength of soil, usually in four samples at different vertical pressure applied shear force of shear, shear stress at failure is obtained, and then determined according to Coulomb strength parameters, angle of internal friction and cohesion

Second, the main technical indicators

The maximum vertical load (KPa): 400
Pressure (KPa): 50,100,200,300,400
Weight weight (KPa): 1.275,2.55,5.1,7.65,10.2
Leverage ratio: 1:12
Sample: 30cm2 2cm
Maximum horizontal shear (KN): 1.2
Power type: manual
