【課題】
【解決手段】 土中に掘削ホールを形成する回転可能なカッタを有する土中掘削ドリルビットを構成する。 切削エレメントの少なくとも一の外周列が、岩盤に余掘を作って、トラッキングを除去するように最適化されており、ここで選択されたピッチが数学的に決定した対を有し、選択されたピッチとその対間の絶対差が、その外周列の最大ピッチと最小ピッチ間の差の10%以上である。 更に、切削エレメントが、予め選択された母線に沿って、当該母線から変位された配置されており、この変位は前記切削エレメントによって占められている外周列の最大ピッチの半分以下である。 本発明は、従来の石油、ガス、およびショットホール掘削井戸用のローラカッタドリルビットに比べて、トラッキングを除去し、有害な軸上共鳴周波数振動を低減する一方で、タングステン−カーバイドインサートを含む切削エレメントの数を減らし、同時に掘削長さ、掘削速度および耐久性を上げる。 【選択図】 図8 |

PROBLEM TO BE SOLVED: To cut reinforcements buried to an existing pipe made of reinforced concrete efficiently and surely by forming the spiral type edge section of a spiral type roller cutter in a plurality of strips in a cutter head for a tunnel boring machine. SOLUTION: Cutter bits 4 are fixed onto a cutter head 1 for a tunnel boring machine while spiral type roller cutters 3, 3 and disk cutters 5, 5 are installed rotatably. The spiral type edge sections 3a of the spiral type roller cutters 3, 3 are formed in a plurality of strips at pitch angles of 20-80 deg., and the pitch angles are oppositely directed mutually as occasion calls. When one of the spiral type roller cutters 3 is replaced with a discoidal roller cutter and the discoidal roller cutter is mounted in the front in a fixed quantity, the concrete section of an existing pipe is crushed by the discoidal roller cutter, and projecting reinforcements are bent in the direction of rotation of the cutter head 1, and cut by the spiral type roller cutter 3. Accordingly, the reinforcements buried to the existing pipe are cut efficiently and surely by the spiral type roller cutters 3. | ||||||

PURPOSE: To improve efficiency by installing a rotary tool and a brush rotatably supported by a support body to be integrated with circumferential surfaces of plural cutting wheels which are rotated in the opposite directions to each other, and setting the axis of the rotary tool to be parallel to the rotation axis of the cutting wheel. CONSTITUTION: A rotary tool 14 and a brush 15 on which circular cutting edges 16 are rotatably installed by fork-shaped support bodies 7 are installed along the whole circumferences of cutting wheels 5, 7 which are rotated in the opposite directions to each other. Next, the cutting wheels 5, 7 are continuously rotated, and cutting is conducted by the cutting edges 16 having a roughly parallel rotation axis to the axis of the cutting wheels 5, 7. Crushed soil is taken into the cutting wheels 5, 7 by the brush 15 to be supplied to a suction device 17. Cutting by the cutting wheels 5, 7 can thus be efficiently realized.

PURPOSE: To enable the stable drilling of a well bore with a slight pressing force and to improve a cost/performance ratio. CONSTITUTION: A vertically long duct is arranged inside a drill main body 10 to be rotated about a vertical axis of rotation 20 for supplying a fluid to a well bore. At least one cutting discs 34, 36, and 38 are provided on the outside part of the main drill body 10. A plurality of cutting blades 35, 37, and 39 in a ring shape are arranged in each disc. The axis of rotation of each of the discs 34, 36, and 38 is disposed at a relatively acute angle of inclination to the main axis of rotation 20. In addition, the axis of rotation of each disc is slightly offset laterally in a rearward direction from the main axis of rotation 20 of the drill main body 10. These location relationships of the axes of rotation causes the entire drill to be placed in a non-equilibrium position with the rotation of the drill main body 10 and the cutting discs 34, 36, and 38 to be more effectively and actively moved in cutting the well bore. | ||||||
