C041-A Digital soil site four-bladed vane Shear apparatuS
-EndFragment-->
This Field Vane Test is used for the determination of soft clay soil, saturated clay natural shear strength.
Test:Press cross slab head equipped with four blades into depth of the reservation, And cross slab head rotation, measure The resistance of the cylindrical surface is required formed by Vane shear head.
Then put the equivalent resistance of shear resistance on the surface of the cylindrical units
It is very important to calculate force of friction of Cross plate drilling and rotating equipment, or friction will mistakenly think that is the strength of the soil
Cross plate drilling rod should have sufficient strength under the condition of full load , in order not to make the drilling rod distorted, or Torque Angle of rotation curve must be amended.
