Description
Claims (1)
- 【特許請求の範囲】 1. 掘削が進むとき穴に取り付けられる保護チューブ装置が結合され、穴の外 円を掘削するためのリング形状の掘削ビット(2)と、少なくとも回転運動を前 記外ビット(2)に伝達し、穴の中心部を掘削するための円筒内ビット(1)と を有するビット組立体によって土に穴を掘削する方法において、所望位置で前記 外ビット(2)を前記内ビット(1)から取り外すことによって、前記外ビット (2)による掘削と前記保護チューブ(4)の引出しを止めて、その後前記内ビ ット(1)だけで掘削を続けることを特徴とする掘削方法。 2. 差し込みジョイント内の突出部分(3)によって内ビット(1)が衝撃を 外ビット(2)に伝達しなから、ビット(1、2)を打ち込むことによって、掘 削を行う請求の範囲1に記載の方法。 3. 前記内ビット(1)を各方向に前記外ビット(2)の中に押し込み、必要 なときに外ビットを内ビットに係止することができる請求の範囲1及び2に記載 の方法。 4. 穴の第1部分及び第2部分をそれぞれ完備したビット組立体(1、2)及 び前記内ビット(1)によって掘削し、前記内ビットを単独或いはリングビット (2)及び略チューブ(4)といっしょのいずれかで前記穴から取り除く請求の 範囲1乃至3のいずれかに記載の方法。 5. 穴の中心を掘削する内ビット(1)と、穴の外円を掘削するリングビット (2)と、前記ビット間の少なくとも回転伝達用ジョイントと、掘削中にボア内 に取り付けられ、前記外ビット(2)に結合される保護チューブとを有するビッ ト組立体において、前記内ビット(1)を各方向から前記外ビット(2)にネジ 込み、両ビットの相互回転によって前記外ビット(2)に係止させ、この係止に よって少なくとも1つのビット(2)が他のビット(1)とともに回転し、且つ 移動することを特徴とするビット組立体。 6. 前記ビット(1、2)の間に1つ或いは複数の一連の差し込みジョイント があり、これらのジョイントの突出部分(3)は、回転運動及び掘削力である衝 撃を前記外ビット(2)に伝達する請求の範囲5に記載のビット組立体。 7. ビット(1)又は(2)のうちの1つの前記差し込みジョイントの軸方向 溝(6)は、フラッシング用媒体の流路でもある請求の範囲5及び6に記載のビ ット組立体。 8. 穴或いはトンネルを掘削するためのユニット型合ビット組立体は、内ビッ ト(1)の円筒シェル上に軸方向に対して直交する溝(8)があり、該溝の側面 は内ビット(1)の半径方向に突出し、衝撃及び/又は回転をリングビット(2 )に伝達することを特徴とする、穴の外円を掘削するリングビット(2)ととも に形成する内ビット。 9. 前記シェルに1つ或いは複数の軸方向溝(6)がある請求の範囲8に記載 の内ビット。 10.前記シェルに、軸方向に順に配置された数個のリング形状溝(8)があり 、該溝は壁(9)で終わる請求の範囲8及び9に記載の内ビット。
