CIRCULAR PILE EXPANSION EXCAVATING APPARATUS
The present invention relates to an apparatus for installation of a circular pipe by inner excavation that can excavate using centrifugal force while the expansion blades are automatically deployed by friction with the ground. According to an embodiment of the present invention, an apparatus for installation of a circular pipe by inner excavation comprises: an excavation shaft which is inserted into a circular pile penetrating into the ground and rotates; at least one first expansion blade coupled to the excavation shaft to rotate; and a connecting plate coupled to the first expansion blade and supporting the first expansion blade in close contact with the excavation shaft when the first expansion blade is deployed.
본 발명은 원형관 중굴용 굴착장치에 관한 것으로, 본 발명의 실시예에 따른 원형관 중굴용 굴착장치는 지반에 관입되는 원형관에 삽입되어 회전하는 굴착샤프트와, 상기 굴착샤프트에 결합되어 회동하는 적어도 하나 이상의 제1 확장날개와, 상기 제1 확장날개에 결합하며, 상기 제1 확장날개의 전개시 상기 굴착샤프트에 밀착하여 상기 제1 확장날개를 지지하는 연결판을 포함한다.
