CONSTRUCTION METHOD OF FRICTION CUTTING IN GROUND, AND CONSTRUCTION DEVICE FOR FRICTION CUTTING IN GROUND
To provide a construction method of friction cutting in the ground capable of efficiently pulling a steel member out of the ground and burying it into the ground.SOLUTION: A construction method of friction cutting in the ground comprises: a voltage application step of applying direct voltage between an object member which is an object to be pulled out of the ground or to be buried in the ground and an anode member of which at least a part is buried in the ground at a position spaced apart from an installation position of the object member so as to make the object member a cathode and the anode member an anode; and an installation step of starting either of installations of pulling the object member out of the ground or burying it into the ground, during the direct voltage is applied within five minutes after applying the direct current voltage at the voltage application step.SELECTED DRAWING: Figure 1
【課題】鋼部材の地中からの引き抜きや地中への埋設をより効率的に行うことが可能な地中フリクションカット施工方法を提供する。【解決手段】地中フリクションカット施工方法は、地中からの引き抜き対象または前記地中への埋設対象となる対象部材と、前記対象部材の設置位置から離間した位置において少なくとも一部が前記地中に埋設された陽極部材との間に、前記対象部材が陰極、前記陽極部材が陽極となるように直流電圧を印加する電圧印加ステップと、前記電圧印加ステップによる前記直流電圧の印加後の５分以内であって前記直流電圧が印加されている時に、前記対象部材の前記地中からの引き抜き、または、前記対象部材の前記地中への打ち込み、のいずれかの施工を開始する施工ステップと、を備える。【選択図】 図１
