Abstract
Description
터널내 탄성파 반사법 탐사를 수행함에 있어 국내에서는 모든 장비를 수입하여 사용하고 있다. 따라서 장비 자체도 상당히 고가이지만 센서를 터널 벽면에 설치하기 위한 소모품인 케이스조차 국내에 규격품이 없음으로 인해 수입하여 사용함으로써 외화낭비를 초래하고 있다. 따라서 시중에 흔히 구할 수 있는 시제품을 케이스로 쓰기 위해서는 센서와 케이스가 밀착되면 됨으로 이에 대한 기술을 개발하고자 한다.In the seismic reflection survey in tunnels, all equipment is imported and used in Korea. Therefore, the equipment itself is quite expensive, but even the case, which is a consumable for installing the sensor on the tunnel wall, is imported and used because there is no standard product in Korea, resulting in waste of foreign currency. Therefore, in order to use a commercially available prototype as a case, the sensor and the case need to be in close contact with each other.
지중에서 반사되어온 반사파를 센서가 감지하기 위해서는 필수적으로 케이스와 센서가 이격됨으로써 발생되는 에너지의 감소 영향을 최소한으로 줄여야 한다. 따라서 이러한 문제점을 해결하기 위해 탄성력이 뛰어난 판스프링을 사용하여 케이스에 센서를 삽입하기 전에는 센서 지지대에 설치된 코일스프링에 의하여 판스프링이 본래의 탄성력을 유지하도록 도와주며, 케이스에 센서를 삽입 시는 판스프링이 압축력을 받음으로써 센서가 케이스 상단과 밀착되는 장력이 발생하며, 동시에 센서 지지대에 설치된 코일스프링 또한 판스프링의 장력에 의해 압축되게 된다.In order for the sensor to detect the reflected wave reflected from the ground, it is essential to minimize the effect of energy reduction caused by the case and the sensor spaced apart. Therefore, in order to solve this problem, the plate spring helps to maintain the original elastic force by the coil spring installed on the sensor support before inserting the sensor into the case by using the plate spring with excellent elasticity. As the spring receives the compressive force, a tension is generated in which the sensor is in close contact with the top of the case, and at the same time, the coil spring installed on the sensor support is also compressed by the tension of the leaf spring.

도1은 본 발명에 대한 개략적인 입체도 및 센서부를 확대한 분해도이며, 도2는 센서를 케이스에 삽입하기 전과 삽입후의 판스프링과 코일스프링의 변화된 모습을 보여주고 있다.FIG. 1 is a schematic exploded view of the present invention and an enlarged exploded view of a sensor unit, and FIG. 2 shows a changed state of a leaf spring and a coil spring before and after insertion of a sensor into a case.
도1에서 판스프링(1)은 센서를 케이스에 삽입 시 압축됨으로써 센서를 케이스와 밀착시키는 역할을 수행한다. 코일스프링(2)는 센서와 연결된 지지대(5) 속에 내장됨으로써 평상시는 판스프링에 장력을 전달하여 판스프링이 탄성력을 유지하도록 도와주며, 케이스에 삽입 시는 판스프링에 의한 장력만큼 압축됐다가 다시 센서를 케이스에서 빼내면 본래의 탄성력을 유지하도록 하였다. 센서(3)는 가속도계라고도 칭하며 송신부에서 발생한 탄성파를 감지하는 역할을 한다. 코일스프링 가이드(4)는 센서 연결 지지대(5) 속에 코일스프링을 설치하기 위해 만든 것으로 코일의 가이드 역할을 한다. 센서 연결 지지대(5)는 센서(3)와 고정볼트(6)로 연결되며 판스프링이 장력에 의해 자유롭게 이동할 수 있는 통로를 제공한다.In FIG. 1, the leaf spring 1 compresses the sensor when the sensor is inserted into the case, thereby closely contacting the sensor with the case. The coil spring (2) is embedded in the support (5) connected to the sensor, so that the tension is normally transmitted to the leaf spring to help the leaf spring to maintain the elastic force, when inserted into the case is compressed by the tension of the leaf spring and then again When the sensor was removed from the case, the original elastic force was maintained. The sensor 3, also called an accelerometer, serves to sense the acoustic wave generated in the transmitter. The coil spring guide 4 is made to install the coil spring in the sensor connection support 5 and serves as a guide of the coil. The sensor connection support 5 is connected to the sensor 3 and the fixing bolt 6 and provides a passage through which the leaf spring can move freely by tension.
센서연결케이블통로(7)는 센서와 연결될 케이블을 위해 원통형으로 통로를 설치하였다. 지지대연결 파이프(8)은 지지대 사이를 연결해 주며 동시에 센서 케이블이 설치될 통로이기도 하다. 중간 처짐 방지 지지대(9)는 연결 파이프 자체의 자중에 의한 처짐을 방지하며 동시에 센서가 원활하게 케이스에 삽입될 수 있도록 도와준다.The sensor connection cable passage 7 is provided with a cylindrical passage for the cable to be connected to the sensor. The support connecting pipe 8 connects between the supports and at the same time, it is also a passage where the sensor cable is to be installed. The intermediate deflection prevention support 9 prevents deflection by self-weight of the connection pipe itself and at the same time helps the sensor to be smoothly inserted into the case.
끝단 처짐 방지 지지대(10)는 연결파이프(8)의 자중을 받아주며 센서를 삽입 및 인출 시 사용되는 손잡이(11) 및 케이블 연결 커넥터(12)의 고정대 역할을 한다.End deflection prevention support 10 receives the weight of the connection pipe 8 and serves as a holder of the handle 11 and the cable connection connector 12 used when inserting and withdrawing the sensor.
이상과 같은 본 발명에 의하면 센서에 정확히 맞는 케이스를 구입할 필요 없이 시제품 중에 적합한 것을 선택하여 판 스프링 및 코일 스프링의 장력을 조절하여 사용할 수 있음으로 수입대처 효과 및 장비의 원할 한 개발에 도움을 준다.According to the present invention as described above can be used to adjust the tension of the leaf spring and coil spring by selecting a suitable one from the prototype without the need to purchase a case that exactly fits the sensor, and helps in the effect of import countermeasures and the development of the equipment.
