DEVICE AND METHOD FOR INSTALLING PILE ON BEDROCK
PROBLEM TO BE SOLVED: To provide a device and a method for installing a pile in a bedrock by which a pile is installed while removing rock crushed by an impact from the pile installation with water jet, thereby preventing clogging by sediment of a tip nozzle on an introduction pipe from which the water jet is injected.SOLUTION: A pile 6 is installed in a bedrock R by driving with a vibration pile installation machine, the pile 6 having an introduction pipe 4 disposed adjacently and being installed by crushing the bedrock R with a tip of the pile 6 struck on the bedrock R by the vibration pile installation machine, while removing the crushed rock by water W injected from a tip nozzle 5 fitted at a tip of the introduction pipe 4. A cover body 2 is fitted on the pile 6 for closing an injection port 5a of the tip nozzle 5, and the pile 6 is installed in a sediment layer S above the bedrock R with the cover body 2 covering the injection port 5a of the tip nozzle 5. When installing the pile 6 in the bedrock R, the tip nozzle 5 is removed from the cover body 2 and the water W is injected from the tip nozzle 5 for removing the crushed rock.SELECTED DRAWING: Figure 4
【課題】打設杭の打撃により破砕された破砕岩を噴射水で排除しながら杭を打設する際に、噴射水を噴射する導入パイプの先端ノズルの土砂による目詰まりを防止できる岩盤への杭打設装置および工法を提供する。【解決手段】振動杭打設機により打設される杭６に導入パイプ４を隣接配置し、杭６の先端を振動杭打設機により岩盤Ｒに打ち付けて岩盤Ｒを破砕し、破砕した岩石を導入パイプ４の先端に設けられた先端ノズル５から噴射する水Ｗで排除しながら岩盤Ｒ中に杭６を打ち込む際に、杭６に先端ノズル５の噴射口５ａを塞ぐカバー体２を取り付け、カバー体２により先端ノズル５の噴射口５ａを塞いだ状態で岩盤Ｒの上方に存在する土砂層Ｓに杭６を打設し、岩盤Ｒに杭６を打設する際には先端ノズル５をカバー体２から取り外した状態にして、先端ノズル５から水Ｗを噴射し、破砕岩を排除する。【選択図】図４
