The invention relates to a drilling machine for road construction. The problem that an existing drilling machine cannot change directions and replace rods automatically is effectively solved. According to the technical scheme, the drilling machine comprises a workbench, a drill hole is formed in the workbench, the workbench is integrally connected with a locating circular ring by a supporting column located near the drill hole, and a locating circular ring thread is arranged on the inner wall of the locating circular ring in a tapping mode. A rotating rod is arranged in the locating circular ring, a rotating rod thread is arranged on the outer wall of the rotating rod in a tapping mode, the rotating rod meshes with the locating circular ring in a threaded mode, and a drill rod is connectedto the lower end of the rotating rod in a threaded mode. A driving screw is arranged next to the drill rod in a threaded and meshing mode, the rotating rod can drive the locating circular ring to move rotatably up and down i
