Description

터널 변위측정용 타켓 및 그 설치방법{a target for measure the displacement in tunnel and method for installation thereof}Target for measuring tunnel displacement and its installation {a target for measure the displacement in tunnel and method for installation

본 발명은 터널의 내공 변위 및 천단 침하를 측정하기 위해 터널의 내부에 설치되는 타켓의 미 사용시 외부 돌출을 방지하여 발파 또는 버럭처리 작업시 타켓의 파손을 미연에 방지할 수 있도록 하는 터널 변위측정용 타켓 및 그 설치방법에 관한 것이다.The present invention is for tunnel displacement measurement to prevent the external protrusion when the target is not used in the interior of the tunnel to measure the internal displacement of the tunnel and the sinking of the tunnel to prevent the damage of the target during the blasting or bagging process It relates to a target and its installation method.

일반적으로, 기차나 차량 등의 운행을 원활하고 사회 간접 자본의 확충을 위해 터널의 시공이 활발히 이루어지고 있는 바, 터널의 시공 공법도 새로운 기술이 개발되어 나날이 발전하고 있는 추세이다.In general, the construction of tunnels is actively performed to smoothly operate trains and vehicles, and to expand social indirect capital. As a result, new technologies are being developed every day.

이러한 터널 시공에는 새로운 첨단 공법이 적용되더라도 여러 가지 불확실한 요소들이 많이 존재하게 되는데, 그 중에서도 지질학적인 불확실성이 가장 중요한 문제점으로서 대두 되고 있으며, 이미 시공된 터널의 경우에도 노후화로 인하여 터널 내공의 변위가 발생하게 되면 터널 구조물의 붕괴에 의해 대형사고가 발생할 가능성이 있다.In this tunnel construction, there are many uncertainties even though the new advanced construction method is applied. Among them, geological uncertainty is emerging as the most important problem, and in the case of tunnels that have already been constructed, displacement of tunnel interior occurs due to aging. In this case, there is a possibility that a major accident occurs due to the collapse of the tunnel structure.

이러한 문제점들을 미연에 방지하기 위해, 최근에는 터널 내공의 변위량을 측정하는 방법이 개발되고 있는데, 대표적인 방법으로서 터널 내공에 반사판을 갖춘 소형의 타겟 구조물을 부착하고, 기준지점에서 레이저 광선을 측정하고자 하는 타겟 구조물에 발사함에 의해, 반사되어 돌아오는 광선의 속도에 의해 길이를 파악하고, 소정의 기준 좌표점과 해당 터널의 측정점과의 각도 변위량을 측정함으로써, 길이와 각도 변위량에 근거한 터널 내부의 내공 변위량을 파악할 수 있도록 하고 있다.In order to prevent these problems, a method of measuring displacement of tunnel holes has recently been developed. As a representative method, a small target structure having a reflector is attached to a tunnel hole and a laser beam is measured at a reference point. By firing on the target structure, the length is determined by the speed of the reflected light and the amount of angular displacement in the tunnel based on the length and the angular displacement is measured by measuring the angular displacement between the predetermined reference coordinate point and the measured point of the tunnel. To understand.

이와 같은 기술과 관련되어 실용신안등록 제446441호에 폴더형 측량 타겟이 개시되어 있으며 그 구성은 도1에서와 같이, 터널면에 고정되는 지지 패널(10)과 타켓이 구비되는 반사판(16)이 볼트 및 너트(24)로서 회전가능하게 연결될 때 그 후면 소정 부위에는 스프링 고리(25,27)가 각각 형성되어 이에 탄성 스프링(29)의 양단이 고정적으로 연결되어 있는 바, 상기 탄성 스프링(29)은 상기 반사판(16)이 외력에 의한 충격으로 전방으로 이동되면 그 자체 복원력에 의해 전방으로 이동된 반사판(16)을 원래 위치로 회동시켜서 복원되도록 하는 역할을 수행하는 구성으로 이루어진다.In connection with such a technique, Utility Model Registration No. 444441 discloses a foldable survey target. The configuration thereof includes a support panel 10 fixed to a tunnel surface and a reflector 16 provided with a target. When it is rotatably connected as a bolt and nut 24, the spring ring (25, 27) is formed in a predetermined portion of the rear surface, so that both ends of the elastic spring 29 is fixedly connected, the elastic spring 29 When the reflecting plate 16 is moved forward by the impact of the external force is made of a configuration that serves to restore by rotating the reflecting plate 16 moved forward by its own restoring force to its original position.
