ANCHOR CONSTRUCTION METHOD, ROPE LYING METHOD AND ANCHOR STRUCTURE BODY
To provide an anchor construction method, a rope lying method and an anchor structure body that can ensure fixing strength of stones and anchor.SOLUTION: An anchor construction method is a method of driving the anchor into stones 30 and includes a process of drilling a hole 32 through the stones 30 at a planned insertion part of the anchor, a process of forming a foam body 40 inside the hole 32 and in an external space 31 adjacent to the hole 32 by injecting a polyurethane foam raw material into the hole 32 and making it foam, a process of removing the foam body 40 inside the hole 32 so that the anchor can be inserted and a process of inserting the anchor into the hole 32 from which the foam body 40 has been removed.SELECTED DRAWING: Figure 4
【課題】石とアンカーの固定強度を確保できるアンカー施工方法、ロープ伏せ工法、及びアンカー構造体を提供する。【解決手段】アンカー施工方法は、石３０にアンカーを打ち込むアンカー施工方法であって、アンカーの挿入予定部位に、石３０を貫通する穴３２を開ける工程と、穴３２にポリウレタンフォーム原料を注入して、発泡させることで、穴３２の内部と、穴３２に隣接した外部空間３１に発泡体４０を形成する工程と、穴３２の内部の発泡体４０を、アンカーが挿入可能となるように取り除く工程と、発泡体４０が取り除かれた穴３２にアンカーを挿入する工程と、を備えている。【選択図】図４
