ABSTRACT:
PCT No. PCT/US79/00495 Sec. 371 Date July 11, 1979 Sec. 102(e) Date July 11, 1979 PCT Filed July 11, 1979
A compacting apparatus (10) has an impact apparatus (17) and a compactor (19). The impact apparatus (17), such as, for example, a rock breaker, provides impacting forces on the compactor (19). The compacting apparatus (10) is positioned on, for example, a work structure (12,14,15) of a work vehicle (16). It is necessary to compact material in order to provide, for example, proper filling of a trench (74) after a pipe has been placed in the trench. Compaction, as done by the compacting apparatus (10), is provided by simultaneously compacting the material and applying a compressive force to the material and remolding the material. Therefore, satisfactory compaction can be provided in the trench (74) by the work vehicle (16) which is also usable to excavate and refill the trench (74).
