GROUND ANCHOR AND INSTALLATION METHOD
PROBLEM TO BE SOLVED: To provide a ground anchor and an installation method thereof capable of extending the service life of the anchor without requiring any new anchor to be installed even when the ground around tendon restraint length has degraded.SOLUTION: Disclosed ground anchor (10) includes a first anchor body (1, anchor body of an old anchor) and a second anchor body (2, anchor body for service life extension), which are inserted in the same anchor hole (H). The first anchor body (1) is shorter than the second anchor body (2). The tendon restraint length (L1) of the first anchor body (1) is positioned closer to the upper part of the ground than the tendon restraint length (L2) of the second anchor body (2).SELECTED DRAWING: Figure 2
【課題】テンドン拘束長周囲の地盤が劣化しても新たにアンカーを打つ必要がなく、アンカーの延命化を行うことが出来るグラウンドアンカーとその施工方法の提供。【解決手段】本発明のグラウンドアンカー（１０）は、第１のアンカー体（１：先行使用アンカーのアンカー体）及び第２のアンカー体（２：延命用アンカーのアンカー体）が同一のアンカー孔（Ｈ）に挿入されており、第１のアンカー体（１）は第２のアンカー体（２）よりも短く、第１のアンカー体（１）のテンドン拘束長（Ｌ１）は第２のアンカー体（２）のテンドン拘束長（Ｌ２）よりも地上側に位置している。【選択図】図２
