VIBRATORY COMPACTION IN THE LABORATORY OF GRANULAR MATERIALS IN LONG COLUMNS

FOR A LABORATORY STUDY OF THE DRAINAGE OF LONG COLUMNS OF POROUS MEDIA, A MAXIMUM DENSITY, UNIFORMLY DISTRIBUTED THROUGHOUT THE COLUMN, WAS REQUIRED. RESEARCH RESULTED IN THE DEVELOPMENT OF A MECHANICAL TECHNIQUE FOR THE PACKING OF DRAINAGE COLUMNS, AS MUCH AS 60 IN. LONG, WITH GLASS BEADS AND NATURAL SANDS OF VARIOUS PARTICLE SIZES. A VIBRATORY PACKER USED TO PACK THESE COLUMNS, WHICH ARE 1 TO 8 IN. IN DIAMETER, PROVIDED GOOD REPRODUCIBILITY OF DRY UNIT WEIGHT AND POROSITY BETWEEN DUPLICATE COLUMNS AS WELL AS A VERTICAL UNIFORMITY OF THESE PROPERTIES WITHIN THE SAME OR DUPLICATE COLUMNS. TO DEVELOP THE STANDARD METHOD OF PACKING COLUMNS, A STUDY WAS MADE OF THE EFFECTS OF TIME, AMPLITUDE, AND SURCHARGE WEIGHT ON THE UNIFORMITY AND REPRODUCIBILITY OF RESULTS. THE TECHNIQUE WAS STANDARDIZED AT A PACKING PERIOD OF 10 S AND A VIBRATORY AMPLITUDE OF 0.09 CM. /AUTHOR/
