Provided in the present invention is a rotationally inserted stake unit, which can be pressed into the ground in a rotational insertion method, and have superior excavating force to shorten the time required for ground insertion. The rotationally inserted stake unit according to the present invention comprises: a stake which can be inserted into the ground from a lower end portion; an excavating unit provided at a lower end portion of the stake so as to penetrate into the ground when the stake is rotated; and a spiral-shaped circular disk coupled to the stake so as to surround a middle portion of the stake. The excavating unit comprises: a support plate coupled to the stake so as to cover an end of the stake; and an excavating blade protruding in a semi-circular disk erected vertically to the support plate so as to be convex from the support plate to the downwards.
본 발명은 회전관입 방식으로 지반에 압입 가능하고, 굴착력이 우수하여 지반 관입 시간을 단축할 수 있는 회전관입 말뚝유닛을 제공하기 위한 것이다. 본 발명에 의한 회전관입 말뚝유닛은, 하단부로부터 지반 속으로 관입될 수 있는 말뚝과, 말뚝의 회전 시 지반을 뚫고 들어갈 수 있도록 말뚝의 하단부에 구비되는 굴착부와, 말뚝의 중간 부분을 감싸도록 말뚝에 결합되는 나선형원판을 포함한다. 굴착부는, 말뚝의 끝단을 덮도록 말뚝과 결합되는 지지판과, 지지판으로부터 하측으로 볼록하게 지지판에 대해 수직으로 세워진 반원판 형상으로 돌출되는 굴착날을 포함한다.
