COMPACTING/REINFORCING METHOD FOR SEDIMENT AND FORMATION OF DITCH/DITCH BOTTOM SECTION

摘要

PROBLEM TO BE SOLVED: To strongly compact back-filled soil and crushed stones at a place narrow in width and form a ditch on the ground surface without generating waste soil. ;SOLUTION: A guide tube 10 having a shock reception section 11 at the bottom section is integrally erected at the center of the back face of a compacting plate 9 to form a compacting tool 8, and the crushing head 4 of a vibration crusher 3 fitted at the tip of the boom of a construction machine is inserted into the guide tube 10 of the compacting tool 8. The compacting tool 8 is suspended at the tip of the boom while a gap is left between the tip of the crushing head 4 and the shock reception section 11, the crushing head 4 is faced downward, the surface of the compacting tool 8 is brought into contact with the sediment surface, and the crushing head 4 is excited to compact the sediment or form a ditch. When the ditch or a ditch bottom section is to be formed via compaction, the finishing compacting tool 8 provided with the compacting plate 9 having the flat surface and a digging compacting tool provided with a compacting plate formed with V-shaped protruded stripes on the surface can be used in turn.;COPYRIGHT: (C)1997,JPO
