CIRCULAR PILE EXPANSION EXCAVATING APPARATUS
The present invention relates to an excavation apparatus for internal excavation of a circular tube that can be excavated by centrifugal force while extended wings are automatically deployed by friction with the ground. According to an embodiment of the present invention, the excavation apparatus for internal excavation of a circular tube comprises: an excavation shaft which is inserted into a circular tube penetrating into the ground and rotates; and at least one extension wing which is pivotally connected to one side of the excavation shaft and are deployed by friction with the ground while the excavation shaft is rotated.
본 발명은 원형관 중굴용 굴착장치에 관한 것으로, 본 발명의 실시예에 따른 원형관 중굴용 굴착장치는 지반에 관입되는 원형관에 삽입되어 회전하는 굴착샤프트와, 상기 굴착샤프트의 일측에 회동연결되며, 상기 굴착샤프트가 회전화면서 지반과의 마찰에 의해 전개되는 적어도 하나 이상의 확장날개를 포함한다.
