Title:
ROAD SURFACE DRILLING EQUIPMENT AND ROAD SURFACE DRILLING METHOD
Document Type and Number:
Japanese Patent JP2009191492
Kind Code:
A
Abstract:

To provide road surface drilling equipment and a road surface drilling method, which enable the easy drilling of a hole capable of being controlled to a desired depth and excellent in reproducibility, which can inhibit dust, produced by the drilling, from being diffused around, and which can reduce labor for the drilling.

This road surface drilling equipment for drilling a road surface comprises: a bit 3 which drills the road surface by reciprocating in a direction almost orthogonal to the road surface while rotating; a driving means 4 for moving the bit 3 in rotational and reciprocating directions; and a wheel 31 which can freely change the direction of the movement of the road surface drilling equipment. The road surface drilling equipment enables the control of the amount of the movement of the bit 3 in the direction almost orthogonal to the road surface, and enables the manual drive of the movement of the bit 3 in at least one direction. In addition, the road surface drilling equipment can move by making the wheel 31 rotated by an operator's push.
