INSTALLATION METHOD AND INSTALLATION DEVICE FOR JOINED PILE
PROBLEM TO BE SOLVED: To provide an installation method and an installation device for a joined pile that reduces a number of processes performed on the joined pile.SOLUTION: An installation method for a joined pile is for installing a joined pile 20 in a vertical hole 101 for installation, and includes: a lower pile part supporting step in which a lower pile part 21 that forms a part of the joined pile 20 is hung and supported by a hanging member 7, while at least a part of the lower pile part 21 is inserted into the vertical hole 101; a pile connection step in which a short pile 27 is connected on top of the lower pile part 21 being supported in the lower pile part supporting step; and a hanging and lowering step in which the lower pile part 21 and the short pile 27 connected to each other in the pile connection step are hung and lowered into the vertical hole 101, by sending out the hanging member 7. A connection 13 is located inside the vertical hole 101 in the lower pile part supporting step and the hanging and lowering step, the connection being at a supported position of the lower pile part 21 via the hanging member 7.SELECTED DRAWING: Figure 1
【課題】継杭に施す加工処理を少なくする継杭の建込方法及び建込装置を提供する。【解決手段】建込用の縦孔１０１に継杭２０を建込む継杭の建込方法であって、継杭２０の一部をなす下杭部２１を、当該下杭部２１の少なくとも一部が縦孔１０１内に挿入された状態で、吊下部材７で吊り下げて支持する下杭部支持工程と、下杭部支持工程で支持された状態の下杭部２１の上に短尺杭２７を接続する杭接続工程と、杭接続工程で互いに接続された下杭部２１と短尺杭２７とを、吊下部材７を送り出して縦孔１０１内に吊降ろす吊降ろし工程と、を備え、下杭部支持工程と吊降ろし工程とにおいては、吊下部材７を介した下杭部２１の支持位置である接続部１３が縦孔１０１内に位置する。【選択図】図１
