The present invention relates to an underground wiring pipe position measurement system consisting of a GPS receiver that measures a position of a manhole on the ground and an underground insertion apparatus that identifies an inner diameter of an underground wiring pipe and a position thereof. The underground insertion apparatus comprises: a main body unit which comprises a main body, a first through-hole penetrating along an axis of the main body, a screw room, a screw disposed at a position spaced apart from the first through-hole in the screw room side by side with a longitudinal direction of the main body, a screw room cover, a sensor room, an encoder connected to one side of the screw, an inertial measurement unit installed inside the sensor room, a sensor room cover, a camera detachment unit to which a camera is mounted to be detachable, a towing unit installed with a rope to tow each underground insertion apparatus, and a plurality of fixed hinges installed on an outer surface of the main body; a sliding unit which has a cylindrical unit assembled to be movable along the outer surface of the main body, a protrusion unit coupled to a screw furrow of the screw, and a plurality of moving hinge units; a plurality of guide plates which have a plurality of link units with each one-side end connected to the fixed hinge unit and the moving hinge, respectively, and a connection hinge unit connecting the link units; a camera; and a plurality of first springs which are installed between the sliding unit and the main body unit to provide elastic force so that the guide plates are extended. The present invention has an effect of allowing various components of the underground insertion apparatus not to be easily contaminated. 지상에서 맨홀의 위치를 측정하는 GPS수신기와, 지중관로의 내경 및 위치를 파악하는 지중투입장치로 이루어진 지중관로 위치 측정시스템에 있어서, 상기 지중투입장치는, 본체와, 상기 본체의 축을 따라 관통하는 제 1 통공과, 스크류실과, 상기 스크류실 내에 상기 제 1 통공과 이격된 위치에 본체의 길이 방향과 나란히 배치되는 스크류와, 스크류실 덮개와, 센서실과, 스크류의 일측에 연결되는 엔코더와, 상기 센서실 내부에 설치되는 관성측정부와, 센서실 덮개와, 카메라가 탈착가능하게 장착되는 카메라 탈착부와, 지중투입장치를 각각 견인하기 위한 로프가 설치되는 견인부와, 상기 본체 외면에 설치된 복수 개의 고정 힌지부로 이루어진 본체부와; 상기 본체 외면을 따라 이동가능하게 조립된 원통부와, 상기 스크류의 나사골에 결합되는 돌출부와, 복수 개의 이동힌지부를 구비한 슬라이딩부와; 상기 고정 힌지부와 이동 힌지부에 일측단이 각각 연결되는 복수 개의 링크부와, 상기 상기 링크부를 연결되는 연결 힌지부를 구비한 복수 개의 가이드 플레이트와; 카메라와; 상기 슬라이딩부와 본체부 사이에 설치되어 상기 가이드 플레이트가 확장되도록 탄성력을 제공하는 복수 개의 제 1 스프링으로 이루어진 것을 특징으로 한다.
