Abstract
Description
Claims (1)
- 터널 시공장소의 지반이나 암반의 거동을 알아내는데 사용되는 축력측정장치를 구성함에 있어서,중공의 락볼트 내부에 종방향으로 1∼4곳의 측정위치(POINT)를 설정하여서 각 측정위치에 설치되는 진동현을 얇은 판으로 형성하여 스프링과 결합한 후, 그 양단에 홀다를 일체로 형성하고 상기 홀다를 세트스크류로 고정하여 팽팽하게 유지시키고, 각각의 진동현 에는 트랜스퍼를 설치하여 진동현의 진동주파수를 감지하 하여서 케이블을 통하여 자동계측시스템 등의 계측장치로 전송하도록 구성함을 특징으로 하는 진동현식 다측점 락볼트축력계(VIBRATING WIRE ROCK BOLT STRESSMETER).
