METALLIC GROUND ANCHOR STRUCTURE AND INSTALLATION METHOD THEREFOR
PROBLEM TO BE SOLVED: To provide a metallic ground anchor structure and an installation method therefor that eliminate the need on maintenance and management relating to the structure, that is, achieve so-called maintenance free and prolong the service life, by eliminating the need to supply a rustproof material for corrosion prevention after constructing the ground anchor on a sloped surface, thereby enhancing the anticorrosion property and long-term anchorage property.SOLUTION: A metallic ground anchor has an anchor body part 2, a tension part 3, and an anchor head part 4 formed by a stranded PC steel wire tendon 1 filled and covered with a polyethylene resin. A stainless steel restricting-type spiral spacer 5 is fitted on the anchor body part 2, and a tip of the spiral spacer is covered with a terminal cap 6. The tension part 3 is covered with a polyethylene sheath 7. A stainless steel or a zinc-plated tendon grip 8 is fitted on the anchor head part 4, and a filler 9 that anchors and adheres firmly on the tendon is filled and cured inside the tendon grip.
【課題】金属製グラウンドアンカーの構造及びその設置工法に関し、のり面にグラウンドアンカーを施工した後は、防食のための防錆材の補給を不要とし、耐食性及び長期定着性を図ることで、構造に関する維持管理を必要としないいわゆるメンテナンスフリー化と長寿命化を図る。【解決手段】ポリエチレン樹脂を充填・被覆したＰＣ鋼より線テンドン１でアンカー体部２、引張部３、アンカー頭部４を形成し、アンカー体部２にステンレス製拘束型のスパイラルスペーサー５を嵌合し、且つ当該スパイラルスペーサーの先端に端末キャップ６を被せ、引張部３にポリエチレンシース７を被覆し、アンカー頭部４にステンレス又は亜鉛メッキ製テンドングリップ８を嵌合し、そのテンドングリップ内にテンドンに対する高定着力・固着力を有する定着用充填材９を充填・硬化させることを特徴とする金属製グラウンドアンカー。【選択図】図１
