ROLLING COMPACTOR OF BACK-FILLED SOIL FOR EMBEDDING PIPE LINE

摘要

PURPOSE: To securely compact the lower side of embedded pipes, by connecting a vibration motor and a compacting fork with a flexible hose and vibrating the back-filled soil of the embedded pipes by sticking the fork. ;CONSTITUTION: A rolling compactor 11 of back-filled soil is constituted of a portable small vibratory motor 12 and a flexible hose 14 with a compacting fork. The fork 15 is stuck in the back-filled soil 4 at the lower side of an embedded pipe 3 and the soil is compacted while vibrating by the motor 12. The rolling compaction can be carried out even in a narrow space where a rolling compactor vertically vibrating a compacting plate can not be used. In this way, the lower side of a pipe can be securely compacted.;COPYRIGHT: (C)1996,JPO
