EXPANDABLE CONSTRUCTION APPARATUS FOR FORMING INPROVED GROUND STRUCTURE
The present invention is to provide an expandable ground improvement construction apparatus having improved ground bearing capacity and a ground improvement method using the same. The present invention provides an expandable ground improvement construction apparatus comprising: a rod-shaped body extending long along a center axis; a drilling bit fixed to the leading end of the body; and a hole expansion module comprising a module base part coupled to the body and a hole expansion blade arranged on the outer circumference of the module base part, wherein the hole expansion blade extends in the circumferential direction of the center axis, one end of the hole expansion blade in the extending direction is rotatably coupled to the module base part by a hinge shaft, the other end thereof forms a free end. Moreover, the hinge shaft is arranged in parallel with the center axis, so that the hole expansion blade is folded or unfolded according to the axial rotation direction of the body.
본 발명에 의하면, 중심축선을 따라서 길게 연장되는 막대 형상의 몸체; 상기 몸체의 선단부에 고정되는 천공 비트; 및 상기 몸체에 결합되는 모듈 기초부와, 상기 모듈 기초부의 외주에 배치되는 확공 날개를 구비하는 확공 모듈을 포함하며, 상기 확공 날개는 상기 중심축선의 원주방향을 따라서 연장되며, 상기 확공 날개의 연장방향 일단부는 상기 모듈 기초부에 힌지축에 의해 회전 가능하게 결합되고, 타단부는 자유단을 형성하며, 상기 힌지축은 상기 중심축선과 평행하게 배치되어서, 상기 몸체의 축회전 방향에 따라 상기 확공 날개는 접히거나 펼쳐지는, 확장형 지반 개량체 시공 장치가 제공된다.
