EQUIPMENT TO STUDY THE PERFORMANCE OF SOIL SAMPLERS

AS PART OF A CURRENT RESEARCH PROGRAM INTO TECHNIQUES OF UNDISTURBED SOIL SAMPLING IT IS NECESSARY TO DETERMINE THE INFLUENCE OF A NUMBER OF VARIABLES OF THE SAMPLING OPERATIONS ON THE QUALITY OF THE SOIL SAMPLES OBTAINED. THIS REPORT DESCRIBES IN DETAIL EQUIPMENT WHICH HAS BEEN DEVELOPED AND ASSEMBLED FOR THIS PURPOSE, TOGETHER WITH THE PROCEDURES USED. TRANSDUCERS HAVE BEEN FITTED TO A MEDIUM- SIZED DRILLING MACHINE TO MEASURE THE TORQUE, THRUST, AXIAL DISPLACEMENT AND ROTATIONAL SPEED OF THE DRILL SHAFT. DATA ARE RECORDED IN THE FIELD BY PULSE FREQUENCY MODULATION ON A MAGNETIC TAPE WHICH IS LATER PROCESSED IN THE LABORATORY TO PRODUCE AUTOMATICALLY A PUNCHED PAPER TAPE SUITABLE FOR INPUT TO AN ELECTRONIC DIGITAL COMPUTER. /AUTHOR/
