Summary:In accordance with the present invention, a system for measuring the inside of a manhole through independent frequency radiation in accordance with selective arrangement includes: an external measuring unit formed in a longitudinal direction, having an internal space formed therein, and measuring the depth of a manhole through a scale provided on the outer circumference surface; an internal extension unit provided in the internal space of the external measuring unit, and extended from the inside of the external measuring unit to enable length adjustment; a detachable magnetized indication unit, selectively attached to or detached from the external measuring unit and protruding toward the inner circumference surface of the manhole; and a plurality of investigation units provided to the detachable indication unit to control the degree of light radiation in accordance with the horizontality and position of the external measuring unit. Therefore, the present invention is capable of preventing the detachable indication unit from being displaced due to an external force. 본 발명에 따른, 선택적 배치에 따른 독립적 주파수 조사를 통한 맨홀 내부 메저링 시스템은 장방향으로 형성되며 내부에 내부공간을 형성하고 외주면에 제공되는 스케일을 통해 맨홀의 깊이를 메저링하도록 하는 익스터널 메저링 유닛; 익스터널 메저링 유닛의 내부공간 내에 제공되며, 익스터널 메저링 유닛의 내부로부터 연장되어 길이 조절이 가능하도록 하는 인터널 익스텐션 유닛; 마그네틱 성질을 구비하며, 익스터널 메저링 유닛에 선택적으로 탈부착되며 맨홀의 내주면을 향해 돌출 형성되는 디테처블 인디케이트 유닛; 및 디테처블 인디케이트 유닛에 복수 개로 제공되어 익스터널 메저링 유닛의 위치와 수평에 따라 빛이 조사되는 정도를 조절하는 인베스티게이트 유닛을 포함하는 기술적 사상을 개시한다.
