DRILLING DEVICE FOR REINFORCED CONCRETE BORED PILE
A drilling device for a reinforced concrete bored pile includes drilling masts, a scalable drill rod, a rotary drill bit, a rectangular cutter and scalable cutter rods. A top end of the scalable drill rod is connected to the drilling masts, the rotary drill bit is disposed on a bottom end of the scalable drill rod, the rectangular cutter is disposed above the rotary drill bit and defines a first drill rod hole, the scalable drill rod is disposed to pass therethrough. Bottom ends of the scalable cutter rods are connected to the rectangular cutter, and top ends of the scalable cutter rods are connected to a horizontal constraint platform, on which an impact component is provided. The horizontal constraint platform is disposed below the top end of the scalable drill rod, and the scalable drill rod passes through the horizontal constraint platform and the impact component.
