SLOPED FACE STABILIZATION METHOD
To provide a sloped face stabilization method which can suppress looseness of natural ground with less number of work steps.SOLUTION: A sloped face stabilization method reinforces natural ground 2 and discharges ground water in the natural ground 2 to the outside using a perforated pipe 4 whose tip portion is fastened to the natural ground 2 and whose rear end portion is fixed to a sloped face 2a of the natural ground 2. The method includes: a step of disposing an excavation screw 10 having a rod 11, an excavation head 12 and a screw 13 inside the perforated pipe 4 that is disposed substantially horizontally and inserting the excavation screw 10 and the perforated pipe 4 into the natural ground 2 while rotating the excavation screw 10 (Fig. 2 (A)); a step of injecting grout into the natural ground 2 around the tip portion of the perforated pipe 4 via the excavation screw 10 and fastening the tip of the perforated pipe 4 to the natural ground 2 (Fig. 2 (B)); a step of pulling out the excavation screw 10 out of the perforated pipe 4 (Fig. 2 (C)); and a step of fixing the rear end portion of the perforated pipe 4 to the sloped face (Fig. 2 (D)).SELECTED DRAWING: Figure 2
【課題】作業工数が少なく、地山の緩みを抑制できるのり面安定化工法を提供する。【解決手段】先端部が地山２に定着され、後端部が地山２ののり面２ａに固定される有孔管４によって地山２を補強すると共に地山２中の地下水を外部に排出するのり面安定化工法は、ロッド１１、掘削ヘッド１２及びスクリュ１３を有する掘削スクリュ１０を概ね水平に配置された有孔管４の内部に配置し、掘削スクリュ１０を回転させながら掘削スクリュ１０及び有孔管４を地山２に挿入するステップ（図２（Ａ））と、有孔管４の先端部周辺の地山２に掘削スクリュ１０を介してグラウトを注入し、有孔管４の先端を地山２に定着するステップ（図２（Ｂ））と、有孔管４から掘削スクリュ１０を引き抜くステップ（図２（Ｃ））と、有孔管４の後端部をのり面に固定するステップ（図２（Ｄ））とを含む。【選択図】図２
