To develop a novel method and device for drilling slopes that can achieve a safe working environment and also reduce the weight of a drilling machine assembly itself by numerically setting the tension of a tension wire in consideration of safety, and setting the tension of the tension wire while actually measuring it.SOLUTION: Before a tension wire 6 is stretched to set a drilling machine assembly 2 in the upright position with respect to a slope S, by pulling the tension wire 6 tied to a support 5 with a predetermined tension, it is confirmed that the support 5 can withstand the load applied at the time of drilling. After that, the drilling machine assembly 2 is set in the upright position with respect to the slope S, and a drilling operation is performed.SELECTED DRAWING: Figure 1
【課題】 安全性を考慮したテンションワイヤの張力設定を数値的に把握し、このテンションワイヤの張力を実測しながら設定し、もって安全な作業環境を実現し、更に削孔機組立体自体の軽量化をも達成した新規な法面の削孔方法並びに装置の開発を技術課題とした。【解決手段】 テンションワイヤ６を張設して削孔機組立体２を法面Ｓに対して起立状態に設定する前に、支持体５に結ばれたテンションワイヤ６を所定の張力で引くことにより、支持体５が削孔時にかかる負荷に耐え得ることを確認し、その後、削孔機組立体２を法面Ｓに対して起立状態に設定して、削孔作業を行うことを特徴として成る。【選択図】図１
