Abstract
본 발명은 압축형 앵커의 구조에 관한 것이다. 즉, 압축형 앵커는 종래의 앵커를 사용하는데 가장 제약요소가 되었던 진행성 파괴의 영향, 방수처리기 기술의 미비로 인한 영구앵커로서의 문제점, 시간이 경과함에 따른 크리이프의 영향, 긴장력의 감소등과 같은 결점들을 모두 보완할 수 있고, 현장 작업자의 작업 능력의 차이에 구애 받지 않도록 고안되었으며, 앵커 긴장시에 그라우터의 초기 강도를 증진시키기 위해 그라우터 보강선을 사용했다. 그러나 표준관입시험(N)치가 50 이상의 풍화암 이상의 지반에서는 대단히 높은 인발력을 발휘하는 것을 실험을 통해 확인할 수 있었고, 앵커체 전체가 자유장의 역활을 수행함으로서 종래의 앵커에 비해 탄성회복능력이 월등이 높아 소성변위가 아주 작게 나타나는 특징이 있는 것이다.The present invention relates to a structure of a compression type anchor. In other words, the compression type anchor has the drawbacks such as the influence of the progressive failure which is the most important factor in using the conventional anchor, the problem as the permanent anchor due to the lack of the waterproofing technique, the influence of the creep as time passes, And it was designed not to be affected by the work capacity of the field worker and used the router reinforcement line to improve the initial strength of the router during anchor tension. However, it has been proved through experiment that the extrusion force is very high in the ground of more than 50 weathered rocks with the standard penetration test (N) value, and since the anchor body plays the role of free field, the elastic recovery ability is higher than that of the conventional anchor The plastic displacement is very small.
