CONSTRUCTION METHOD FOR LEANING EARTH RETAINING WALL
PROBLEM TO BE SOLVED: To provide a construction method for a leaning earth retaining wall that eliminates the need to erect a back form and therefore curtails a construction period and enhances construction safety.SOLUTION: A construction method comprises: a first step in which unit bodies 20 comprising lattice-form reinforcements 10, which have a plurality of bent vertical reinforcements 1 and a plurality of horizontal reinforcements 2 that links the plurality of vertical reinforcements 1, and a suction-proof material 4 fixed to the lattice-form reinforcements 10 are prepared and the unit bodies 20 are installed in front of a slope of cut earth or an embankment; a second step in which a backfill material 30 is spread and compacted in the space between the unit bodies 20 and the slope; and a third step in which a surface form 41 is installed in front of the unit bodies 20 and concrete is filled in the space between the surface form 41 and the unit bodies 20 used as a back form and hardened for constructing a leaning earth retaining wall 50.
【課題】もたれ擁壁の施工に際し、裏型枠の施工を不要とし、もって工期の短縮と施工安全性の向上を図ることのできるもたれ擁壁の施工方法を提供する。【解決手段】複数の屈曲した縦筋１と、複数の縦筋１を繋ぐ複数の横筋２と、から構成される格子状鉄筋１０と、格子状鉄筋１０に固定された吸出し防止材４と、からなるユニット体２０を用意し、切土もしくは盛土の法面の前方位置にユニット体２０を設置する第１のステップ、ユニット体２０と法面の間の空間に裏込め材３０を敷き固める第２のステップ、ユニット体２０の前方位置に表型枠４１を設置し、ユニット体２０を裏型枠として、表型枠４１と裏型枠の間の空間にコンクリートを充填し、硬化させてもたれ擁壁５０を施工する第３のステップからなる施工方法である。【選択図】図４
