WASTE VOLUME REDUCTION DISPOSAL METHOD ON WASTE DISPOSAL SITE AND EXCAVATION BODY

摘要

PROBLEM TO BE SOLVED: To enable an efficient execution of compaction hole formation (hole drilling) for waste volume reduction disposal by forming a compaction hole (non-discharge excavation drilling hole) on a disposal site with a high level of ground water such as a landfill disposal site.SOLUTION: An excavation apparatus equipped with an excavation mechanism that uses an excavation body 1, having an opening and closing puncture part 114 provided at the bottom end to turn into a reverse conical shape when closed, a plurality of compaction plates 113 provided downward to press excavated matters, a casing 12 of suitable length, and an airtight lid plate 13 provided at an upward opening part, to excavate under rotation by gripping the casing of an airtight excavation body (while supplying high air of predetermined pressure as needed) is configured by repeating excavation for forming an excavation hole of desired depth with no discharge and reclamation for casting wastes from the upper opening part of the casing with the airtight lid plate opened after the excavation, and for removing the casing with the opening and closing puncture part opened to fill an excavation hole with cast wastes.SELECTED DRAWING: Figure 1
