CONSTRUCTION METHOD OF EARTH RETAINING WALL, AND CONSTRUCTION DEVICE OF EARTH RETAINING WALL
To appropriately construct an earth retaining wall in a vertical shaft.SOLUTION: A construction device 20 includes: a plurality of winches 22 capable of feeding out and winding up a wire 23; and a plurality of position adjustment arms 24 provided below the winches 22 and contacting a cylindrical wall body 31 from the outside to adjust a vertical position. When constructing an earth retaining wall 30, the cylindrical wall body 31 is suspended by the wire 23 and held at a position adjusted by the position adjustment arm 24, and then a vertical shaft is excavated below the cylindrical wall body 31. Further, the cylindrical wall body 31 is lowered into the excavated vertical shaft by feeding out the wire 23 by the winch 22, and another cylindrical wall body 31 is connected to an upper side of the cylindrical wall body 31 with the wire removed. Each of these steps is then repeated until addition of the cylindrical wall body 31 is no longer necessary.SELECTED DRAWING: Figure 1
【課題】立坑内において土留壁の施工を適正に行わせる。【解決手段】施工装置２０は、ワイヤの２３繰り出し及び巻き取りを可能とする複数のウインチ２２と、ウインチ２２よりも下方に設けられ、筒状壁体３１に対して外側から接触し立て位置調整を行う複数の位置調整アーム２４と、を有している。土留壁３０の施工時には、筒状壁体３１を、ワイヤ２３により吊り下げ、かつ位置調整アーム２４により位置調整した状態で保持し、その後、筒状壁体３１の下方に立坑の掘削作業を行う。また、掘削された立坑内に、ウインチ２２によるワイヤ２３の繰り出しにより筒状壁体３１を降下させ、ワイヤ取り外し状態で筒状壁体３１の上側に別の筒状壁体３１を連結する。そして、これら各工程を、筒状壁体３１の追加が不要になるまで繰り返し実施する。【選択図】 図１
