Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a road drilling device for highway maintenance. Background Art

[0002] During the maintenance of the roadbed construction process, when faced with problems such as foundation sinking, cement slurry and other reinforcement materials are injected into the foundation gaps through drilling, which can fill the voids and enhance the density of the soil, thereby effectively preventing the foundation from sinking further and improving the bearing capacity and stability of the roadbed.

[0003] When drilling holes in the roadbed, a rotary drilling rig is generally used to achieve drilling processing in the corresponding area of ​​the roadbed. For example, the Chinese utility model patent disclosed in the application with publication number CN215672023U is: a road drilling device for highway maintenance. The application has a plug-in nail installed in the right front of the moving wheel, and an equipment fixing device installed on the front side of the coolant tank. The geometric position of the drilling device is fixed by the plug-in nail and the front side fixing nail. At the same time, the staff pulls the lifting control handle to realize the lifting of the drilling head. When the drilling head contacts the road, the start button is pressed. At this time, the drilling head When drilling a hole into a highway, if the highway to be drilled is a dirt road surface, a spiral blade can be installed on the outside of the drilling shaft to effectively bring out the dirt on the road surface. Therefore, when drilling a hole in the roadbed, the cushion material of the roadbed will be discharged to the periphery of the borehole through the drilling of the spiral blade. When grouting and other construction operations are required in the borehole, the soil or cushion material around the borehole will affect the construction operation. At the same time, the soil or cushion material will fall into the borehole during the construction operation or cleaning, thereby affecting the subsequent grouting construction and causing the quality of the grouting construction to decline.
