Anchorage Reinforcement Cable Bolts and Anchorage Reinforcement Cable Bolts Method

The present invention relates to an anchorage reinforcement cable bolt. The anchorage reinforcement cable bolt comprises: a steel strand which is formed by a plurality of wound steel wires; a fore-end fixing tool which is coupled to a fore-end of the steel strand; an anchorage tool which is coupled to a rear end of the steel strand; and one or more extension units in which a space is formed as the plurality of steel wires are spaced apart from each other to extend at the middle of the steel strand. The anchorage reinforcement cable bolt of the present invention is provided with the extension units at the middle of the steel strand and increases a frictional force with an injection material filled and hardened in the extension units together, thereby greatly increasing an anchorage force. The anchorage reinforcement cable bolt includes the fore-end fixing tool including a wing unit, so that the fore-end of the steel strand is not unwound, thereby facilitating the insertion into an excavation hole. The anchorage reinforcement cable bolt has the steel strand not one-sided toward a wall surface of the excavation hole, has an enhanced anchorage force, and performs the fastening of the fore-end of the steel strand and the fixation of a pullout prevention spring at the same time, thereby increasing efficiency. 본 발명은 복수의 강선이 꼬여져 형성된 강연선; 상기 강연선의 선단부에 결합된 선단고정구; 상기 강연선의 후단부에 결합된 정착구; 및 상기 강연선의 중간에 상기 복수의 강선이 서로 이격되면서 확장되어 공간이 형성된 하나 이상의 확장부;를 포함하는 정착보강 케이블볼트이다. 본 발명은 강연선의 중간에 확장부를 구비하고 확장부 내부에 충진 경화된 주입재와 함께 마찰력을 증가시켜 정착력이 획기적으로 증가하고, 날개부를 포함한 선단고정구를 포함함으로써 강연선의 선단부가 풀리지 않게 하여 굴착공 내부로의 삽입을 용이하게 하고, 강연선이 굴착공의 벽면에 치우치지 아니할 뿐 아니라 정착력이 증가하며, 강연선 선단부의 결속과 뽑힘방지스프링의 고정을 동시에 수행함으로써 효율이 증가할 수 있다.
