Abstract

하나의 그리고 동일한 드릴 비트 또는 비트 조립체(2,3),(9,10)를 사용하여 바위 또는 점토와 같은 상이한 형태의 흙에 구멍 또는 터널을 만들기 위하여 만들기 위한 방법 및 드릴 장치이다. 비트의 원추형 구성에 의하여 연한 흙이 드릴되는 홀의 측부로 가입되고 비트 전면의 드릴링 요소(5) 수단에 의하여 접하게 되는 돌 바위 등이 비트 후방부를 통하여 제거 가능한 드릴 폐기물로 쪼개진다.Is a method and drilling device for making holes or tunnels in different types of soil such as rock or clay using one and the same drill bit or bit assembly (2,3), (9,10). The conical configuration of the bit joins the soft soil to the side of the hole to be drilled and the stone rock, etc., which is brought into contact by means of the drilling element (5) on the bit front, is broken into a drill waste which is removable through the bit rear part.
