Therefore, when some holes on the road are opened, when the staff drills other parts of the road, the previously opened holes are not blocked, which will cause debris and other impurities on the road to enter the previously opened holes, making it inconvenient for the staff to clean up the debris and other impurities in the holes, reducing the installation efficiency of the guardrail and affecting the normal installation of the subsequent guardrail. In severe cases, it may even cause the guardrail to be installed loosely. Utility Model Content

[0003] The utility model discloses a drilling device for road construction, which solves the problem that after the holes opened on the road are not covered, debris and other impurities may enter the holes, affecting the normal installation of subsequent guardrails, and even causing the guardrails to be installed loosely in severe cases.

[0004] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:
