INVERSE CASING FOR PERFORATING GROUND BORE AND INVERSE CASING MANUFACTURING METHOD THEREOF
According to an embodiment of the present invention, provided is a reverse casing for ground perforation, which comprises: a casing pipe part having a reverse casing groove in the longitudinal direction of a pipe so as to accurately and efficiently perform the post-ground perforation operation when a pre-ground perforation is formed in the ground, and then, a post-ground perforation is formed by overlapping the pre-ground perforation; and a reverse casing pipe part formed by bonding an arc-shaped plate member to the reverse casing groove so that a convex surface faces inward of the pipe.
본 발명의 일 실시예는, 지반에 선 지반천공을 형성한 후, 선 지반천공에 중첩하여 후 지반천공을 형성하는 경우, 후 지반천공 작업을 정확하고 효율적으로 수행할 수 있도록, 관의 길이 방향을 따라 역케이싱홈을 가지는 케이싱관부; 및 상기 역케이싱홈에, 볼록 면이 상기 관의 내측으로 향하도록 원호형 판상 부재가 접합되어 형성된 역케이싱관부;를 포함하여 구성되는 것을 특징으로 하는 지반천공용 역케이싱을 제공한다.
