| description | To provide a rock bolt construction method capable of smoothly and accurately performing rock bolt driving work and preventing accidental dropping of a washer.SOLUTION: A rock bolt construction method comprises a washer holding means installation step of installing washer holding means 8 on a tip side of a guide 34 for holding a washer 9 attached to a rear end of a rock bolt 2, a washer holding step of holding the washer in washer holding means, a rock bolt positioning step of passing a tip end of the rock bolt through a central through hole 90 of the washer 9 held by the washer holding means, a rock bolt driving step of bringing the washer held by the washer holding means close to a wall surface W around a driving hole H, and driving the rock bolt into the driving hole, and a washer installation step of installing the washer so as to support the wall surface W of a tunnel cavity T by removing the washer from the washer holding means and leaving the washer at the rear end of the rock bolt after driving the rock bolt.SELECTED DRAWING: Figure 1
【課題】ロックボルトの打設作業をスムーズかつ正確に行え、かつ、座金の不測の落下を防止できるロックボルトの施工方法を提供する。【解決手段】ロックボルトの施工方法は、ロックボルト２の後端部に取付けられる座金９を保持するための座金保持手段８をガイド３４の先端側に設置する座金保持手段設置ステップと、座金保持手段に座金を保持させる座金保持ステップと、ロックボルトの先端側を座金保持手段に保持された座金９の中央貫通孔９０に通すロックボルト位置決めステップと、座金保持手段に保持された座金を打設用の孔Ｈの周囲の壁面Ｗに近接させるとともに、ロックボルトを打設用の孔に打設するロックボルト打設ステップと、ロックボルトを打設した後に、座金保持手段から座金を離脱させて、当該座金をロックボルトの後端部に残置させることにより、トンネル空洞部Ｔの壁面Ｗを支えるように座金を設置する座金設置ステップとを備えたことを特徴とする。【選択図】図１ |
