Soil Testing System - Direct/Residual Shear Apparatus. 10-2560

DIN 18137 • EN 17892/10 • BS 1377 • ASTM D 3080 for determining the shearing strength of soil.

Soil Testing System - Direct/Residual Shear Apparatus

The apparatus consists of a stable frame with stepper motor drive agitating the carriage with the bottom part of the shear box.

Shearing force, displacement and settlement are measured by means of electronic transducers. The machine is controlle by PC and software, PROPRESS including data aquisition.

Normal load is applied with a loading beam ratio 9:1 and 10:1 and surcharge weights (automatically controlled with option 10-25650).

To ensure that the force is led centrally into the sample, the loading piston is guided in by ball elements. Guiding of the two shear box halves prevents the top part from tilting up during shearing.

The shearing joint between the two shear boxes can simply be set between 0 and approximatelt 1 mm at the water carriage.

The machine is supplied with user programmable operations software "PROPRESS ".

A PC with monitor, keyboard and windows operating system has to be provided. Shear box assembly and load weights are to be ordered in addition.
