Compaction methods and artificial barrier of the granulation product

摘要

PROBLEM TO BE SOLVED: To provide a method for compacting an agglomerated material capable of efficiently and densely compacting the same.;SOLUTION: A method for compacting an agglomerated material comprises: a spreading process to construct an agglomerated material layer 1 by spreading an agglomerated material 2; a first density increasing process to increase density of a superficial portion of the first agglomerated material layer 1; a second density increasing process to increase the density of the remaining portion of the agglomerated material layer 1; and a compaction process to compress the agglomerated material 2. In the method for compacting an agglomerated material, an artificial barrier is constructed by: applying vibration with a first compaction machine 10 having small ground contact pressure in the first density increasing process; applying the vibration with a second compaction machine 10 having larger ground contact pressure than the first compaction machine 10 in the second density increasing process; and compacting the agglomerated material 2 with a third compacting machine having larger ground contact pressure than the second compaction machine in the compaction process.;COPYRIGHT: (C)2014,JPO&INPIT
