STEEL PIPE PILE WITH EXCAVATION JIG, AND ROTARY PRESS-IN METHOD OF STEEL PIPE PILE USING THEREOF AND SEDIMENT DROP DEVICE
PROBLEM TO BE SOLVED: To provide a method to consecutively perform an installation of a mouth pipe and driving of a steel pipe pile.SOLUTION: A rotary press-in method of a steel pipe pile comprises: a first process (P1) to engage a half-split excavation jig, which have a first and a second half cylindrical member each provided with spiral blade members, to the steel pipe pile attached to a pile driver; a second process (P2) to attach the steel pipe pile engaged with the half-split excavation jig to a mouth pipe; a third process (P3) to rotary press-in the mouth pipe in synchronization with rotation of the steel pipe pile engaged with the half-split excavation jig; a fourth process (P4) to excavate soil in the mouth pipe with the steel pipe pile engaged with a half-split excavation jig; a fifth process (P5) to rake out soil deposited between the spiral blade members after lifting up the steel pipe pile engaged with the half-split excavation jig; and a sixth process (P6) to rotary press-in the steel pipe pile in a place where the mouth pipe is pressed-in after the half-split excavation jig is removed from the steel pipe pile.SELECTED DRAWING: Figure 1
【課題】口元管の設置と、鋼管杭の打設を連続して行う工法を提供する。【解決手段】鋼管杭を回転圧入する方法であって、杭打機に取り付けられる鋼管杭に、それぞれ螺旋状羽根部を有する第１、第２の半円筒形部材を有する半割掘削治具を締結する第１の工程（Ｐ１）と、前記半割掘削治具を締結した前記鋼管杭を口元管に取り付ける第２の工程（Ｐ２）と、前記半割掘削治具を締結した前記鋼管杭の回転に連動して、前記口元管を回転圧入する第３の工程（Ｐ３）と、前記半割掘削治具を締結した前記鋼管杭で口元管内を掘削する第４の工程（Ｐ４）と、前記半割掘削治具を締結した前記鋼管杭を引き上げ、前記半割掘削治具の螺旋状羽根間に堆積した土砂を、土砂落とし装置により掻き出す第５の工程（Ｐ５）と、前記半割掘削治具を前記鋼管杭から取り外し、前記鋼管杭を、前記口元管を圧入した箇所に回転圧入する第６の工程（Ｐ６）を有する。【選択図】図１
