PROBLEM TO BE SOLVED: To provide an installation method of an anchor device through a simple work step using one unit of excavation device.SOLUTION: A first installation method uses a bit system 9, and performs the following steps sequentially: a preparation step (S1) in which an outer bit 200 is fitted on an inner bit 100; an excavation step (S2) in which a casing 10 is pressed into an excavation hole 91 while forming the excavation hole 91; a lifting step (S3) in which an excavation hammer 300 is lifted to form a lower space 93; a holding step (S4) in which the casing 10 is held in a way that disables falling; a separation step (S5) in which the outer bit 200 is separated from the inner bit 100; a recovery step (S6) in which the inner bit 100 is pulled out from the casing 10; a filling step (S7) in which mortar 30 is filled in the lower space 93; and an installation step (S8) in which a part of a tension resisting body 20 is penetrated into the mortar 30 and a stopper 50 is pressed against a casing shoe 40.SELECTED DRAWING: Figure 7
【課題】１台の掘削装置を用いた簡素な作業工程によるアンカー装置の施工方法を提供する。【解決手段】第１の施工方法はビットシステム９を用いるものであって、インナービット１００にアウタービット２００を装着する準備工程（Ｓ１）、掘削孔９１を形成しながらケーシング１０を掘削孔９１に押し込む掘削工程（Ｓ２）、掘削ハンマ３００を引き上げて下部空間９３を形成する引き上げ工程（Ｓ３）、ケーシング１０を落下不可能に保持する保持工程（Ｓ４）、アウタービット２００をインナービット１００から切り離す切り離し工程（Ｓ５）、インナービット１００をケーシング１０から引き出す回収工程（Ｓ６）、下部空間９３にモルタル３０を充填する充填工程（Ｓ７）、引張抵抗体２０の一部をモルタル３０に侵入させ、かつ、ストッパー５０をケーシングシュー４０に押し当てる設置工程（Ｓ８）を順番に実行する。【選択図】図７
