Abstract:
PROBLEM TO BE SOLVED: To provide an excavation and rolling machine in which by using one excavation machine, there is not need to mount or dismount a compaction roller and excavated and backfilled sand and earth can be laid and compacted by the mechanical operation on the ground so that noises can be greatly reduced and a pipe burying work can be performed safely and efficiently and rolling can be carried out uniformly and strongly.
SOLUTION: An upper revolving body 4 is mounted on a lower running body 2 through a revolving device 3 and an articulated arm 5 is mounted to the body 4.
