Claims (2)
- 捨石層が存在する水中地面に対して、適宜なケーシングパイプ内に、先方を細径とし基方をケーシングパイプ内径に近い外径を有するスパイラル拡幅部を備えた掘削ロッドを先端に設けた掘削装置を使用し、掘削ビットの先方がケーシングパイプ先端より突出し、スパイラル拡幅部の大径部分がケーシングバイプの下端開口部の近傍に位置させた状態で、ケーシングパイプ上部を密閉し、高圧空気をケーシング内に圧入して、パイプ内海水をパイプ先端から吐き出しながらケーシングパイプと掘削ロッドを回転させて捨石層に押入し、ケーシングパイプが捨石層を貫通したら掘削ロッドを引き抜き、しかる後ケーシングパイプ内に砂を投入し、ケーシングパイプを引き抜いて杭打ち箇所の捨石層を砂層に置換し、当該箇所に所定の杭打ちを行なうことを特徴とする水中構造物用杭打ち工法。
- 掘削ロッドのスパイラル拡幅部に掘削用ビット部を設け、ケーシングパイプ下端面にも掘削用ビット部を設け、捨石層及び捨石層下の地面を掘削しながらケーシングパイプを圧入する請求項1記載の水中構造物用杭打ち工法。
