CIRCULAR PILE EXPANSION EXCAVATING APPARATUS
The present invention relates to an excavator for heavy digging of a circular tube. The excavator for heavy digging of a circular tube according to an embodiment of the present invention comprises: an excavation shaft that is inserted into a circular tube penetrating into the ground and rotates; at least one first expansion blade coupled to the excavation shaft and rotating, and deployed outwardly by friction with the ground; and a connecting plate coupled to the first expansion blade and deployed together. An object of the present invention is to provide an excavator for heavy excavation of a circular tube that can perform excavation by using a centrifugal force while the expansion blade is automatically deployed by friction with the ground.
본 발명은 원형관 중굴용 굴착장치에 관한 것으로, 본 발명의 실시예에 따른 원형관 중굴용 굴착장치는 지반에 관입되는 원형관에 삽입되어 회전하는 굴착샤프트와, 상기 굴착샤프트에 결합되어 회동하며, 지반과의 마찰에 의해 외측으로 전개되는 적어도 하나 이상의 제1 확장날개와, 상기 제1 확장날개에 결합하여 함께 전개되는 연결판을 포함한다.
