REINFORCING ANCHOR, AND REINFORCING METHOD FOR EARTH RETAINING WALL
To provide a reinforcing anchor that can reduce influence of groundwater pressure and buoyancy and can be stably fixed into an anchor fixing hole formed in an earth retaining wall, and a reinforcing method for an earth retaining wall using the same.SOLUTION: A reinforcing anchor 1 comprises a plurality of resin fiber wires 2 inside a sheath 3, and a first end structure 4 at one end 2A and a second end structure 5 at the other end 2B of the resin fiber wires 2. The first end structure 4 includes: a first resin covering the outer periphery of the resin fiber wire 2 and filled between the strands of the resin fiber wire 2; an unbonded tube covering the resin fiber wire 2 via the first resin; and a first heat shrinkable member binding the unbonded tube. The second end structure 5 includes: a second resin covering the resin fiber wire 2 and filled between the strands of the resin fiber wire 2; a second heat shrinkable member binding the resin fiber wire 2 via the second resin; and a hardened portion made of filling material arranged on the outside of the second heat shrinkable member.SELECTED DRAWING: Figure 1
【課題】地下水による圧力や浮力の影響を軽減し安定して土留め壁に形成したアンカー固定穴に固定することができる補強アンカー及びそれを用いた土留め壁の補強方法の提供。【解決手段】複数の樹脂繊維ワイヤー２をシース３の内部に備え、樹脂繊維ワイヤー２の一端部２Ａの第１の端部構造４及び他端部２Ｂの第２の端部構造５とを備え、第１の端部構造４は樹脂繊維ワイヤー２の外周を覆い樹脂繊維ワイヤー２の素線同士の間に充填された第１の樹脂と、第１の樹脂を介して樹脂繊維ワイヤー２を覆うアンボンドチューブと、アンボンドチューブを束縛する第１の熱収縮部材とを有し、第２の端部構造５は樹脂繊維ワイヤー２を覆い樹脂繊維ワイヤー２の素線同士の間に充填された第２の樹脂と、第２の樹脂を介して樹脂繊維ワイヤー２を束縛する第２の熱収縮部材と、第２の熱収縮部材の外側に配置された充填材料からなる硬化部とを有する、補強アンカー１。【選択図】図１
