摘要： PROBLEM TO BE SOLVED: To facilitate a work to move a boring machine, and to facilitate boring in a narrow place and a test in various holes by providing a mobile means by an engine or motor driving and a freely collapsible scaffold. SOLUTION: A boring machine 11 has a mobile means using a crawler belt 18 or wheels to travel, a driving device 17 using an engine or a motor and a freely collapsible scaffold 20 supported by a support member 23. The mobile boring machine 11 traveling to a work place by driving the crawler belt 18 by the driving device 17, stabilizes a chassis 12 by extending support columns 19 of the four corners toward the ground surface. Next, the whole scaffold 20 is supported by the support member 23 by standing the scaffold 20 by extending the collapsible upper part 20b in the extending direction of the lower part 20a by being made vertical with a hinge 21a of the scaffold 20 as a fulcrum. Therefore, work is simplified by eliminating the necessity of separately using a scaffold and a ladder for positioning/installing fixing work of the boring machine, and boring in a narrow place and test work in various holes can be facilitated by facilitating a movement.
