Description

Hole Drilling Machine for Road Marker Construction The present invention relates to a hole drilling machine for installing road markers, and more specifically, to a hole drilling machine for installing road markers installed on road center lines or crosswalks, etc., to guide safe driving for drivers or safe passage for pedestrians, which allows the road markers to be installed in accurate locations by drilling holes at regular intervals while moving in a straight line or while stationary, and provides a dedicated machine to prevent dust scattering during hole drilling. Road markers are one of the marking means installed on roads to limit the driving range of moving vehicles, or are installed on center lines, lane boundaries, road safety zones, in front of crosswalks, speed limiting zones, etc., to promote safe driving. In particular, during night driving, they reflect the headlights of vehicles to alert drivers, or charge solar energy and supply power from batteries to guide safe driving and pedestrian movement. These road markers are provided and installed in various forms, and among these road markers, one hole is drilled at regular intervals or two holes are drilled at regular intervals in the required locations, and the road markers are installed in an exposed form on curbs or at various locations. In order to install the above road markers, the location to be drilled is marked, and then a hole is drilled in the ground using a general drill. Since the road markers are installed in the drilled holes, it is very difficult to install the holes for the road markers in the correct vertical position and to drill the depth accurately, so trained skilled workers are required. In addition, even if the drilling location is marked in advance and a hole is drilled at that location using a drill, there were drawbacks such as the hole positions being inaccurate and the spacing not matching precisely, making it difficult to easily install road markers, and the inability to maintain depth accuracy requiring rework. Due to these various defects, even after the road markers were installed, defects occurred in which various problems were exposed, such as easy separation and detachment due to a lack of accuracy and robustness. In particular, there was a drawback in that dust, dirt, and foreign substances were scattered in various directions and contaminated the surroundings during the work of forming two holes and various drilling operations for the construction of the excavated markers.
