The present invention relates to a method to perform reaming from a start hole in an excavation method, comprising: a step of performing a shooting work at a start hole and performing first excavation to a first excavation section just before an arrival hole; a recovery step of recovering all rods to the start hole; a reaming step of mounting a reamer capable of performing reaming while moving forward from the start hole, so as to perform a reaming work to the first excavation section while moving towards the arrival hole from the start hole; and a step of performing a pulling work simultaneously performing second excavation and reaming works to the arrival hole from the first excavation section. According to the present invention, excavation is performed from the start hole up to only the first excavation section just before the arrival hole, and excavation and reaming are performed from the first excavation section to the arrival hole at the same time with a reamer, which performs reaming while moving forward with a high speed mud motor, so as to reduce human power, equipment, and the like required for the arrival hole, thereby providing an effect capable of reducing a construction period and providing remarkable economic efficiency.
본발명은 굴착공법에서의 시작구로부터 확공을 하는 방법에 관한 것으로, 시작구에서 슈팅작업을 실시하되 도달구 직전인 1차 굴착 구간까지 1차굴착하는 단계; 로드를 모두 시작구까지 회수하는 회수단계; 시작구에서 전진하며 확공이 가능한 확공기를 장착하여 시작구에서 도달구 방향으로 전진하면서 상기 1차굴착 구간까지 확공작업을 하는 확공단계; 1차굴착 구간부터 도달구까지를 2차 굴착 및 확공작업을 동시에 하는 풀링 작업을 하는 단계; 를 포함하는 것으로, 본발명은 시작구에서 도달구 직전인 1차 굴착 구간까지만 굴착을 하고, 1차 굴착 구간부터 도달구까지는 고속의 머드모터와 전진하며 확공이 가능한 확공기를 이용하여 굴착과 확공을 동시에 하면 도달구에 필요한 인력, 장비 등이 절감되어 공사기간을 줄이고 경제적인 현저한 효과가 있다.
